Temperature sensor in a warm field. Installation of a heated floor sensor. How does the principle of temperature control work?

Warm floors are responsible for creating a comfortable atmosphere that has a beneficial effect on well-being. The recommended temperature at the feet is 25°C, and in the head area - 21. It is this mode, which is optimal according to experts, that creates rising heat from the heated floor.

An integral attribute is a thermostat with a temperature sensor built into it - a device at the end of the cable that monitors the degree of heating. When the set values ​​are reached, the heated floor automatically turns off, and when the indicator drops by half a degree, the system starts working again. This ensures a constant climate in the room. In addition, energy consumption is significantly reduced.

Types of sensors

These devices come complete with thermostats, which are divided into:

1. Mechanical. Their operating principle is reminiscent of regulating the degree of heating on irons. The advantage is the cost. Disadvantages: manual mode setting, inability to monitor the temperature due to the lack of a monitor. Examples: BAXI KHG 714086910, Natural NTL-2000, TE 07.

2. Electronic. The presence of a liquid crystal display is the main difference from the previous type of thermostats. On construction market represented by such brands as DEVI Devireg D-131, Electrolux ETB-16.

3. Programmable. Modern devices, automatically maintaining the set mode for a certain period. Characterized by high cost. Similar regulators include models such as Grand Meyer PST-2, Electrolux ETA-16, Caleo UTH-10E.

4. Sensory. They differ from those mentioned above in the way they are controlled.

5. “Smart” thermostat, equipped with or without WI-FI. The most expensive option with many features and settings. It allows you to control the heating via mobile devices. Often built into the wall, and therefore practically invisible.

A “smart” regulator transmits data to the owner’s computer, can monitor the weather forecast, and is often equipped with a built-in calendar. Representatives of the latest developments are able to determine whether there are people in the room. Examples of devices: MCS 300, Nest Learning Thermostat.

The sensors themselves for heated floors are classified according to two bases:

• installation location (internal and external);
• operating principle (digital and analogue).

It is better to place the external one in a dark place, away from heat sources. It is important to exclude the possibility of falling on it sun rays. The mounting height of the thermostat is approximately 1.5 meters from the floor. Devices for indoor installation mounted in a screed or under a film, close to the heating cable. To facilitate their replacement in the event of a malfunction, it is recommended to place the sensors in a pre-laid corrugated hose. They can be connected directly to the thermostat or through a junction box.

The difference between digital temperature sensors and analog ones is that they are more durable. In addition, they are less susceptible to information distortion when exposed to interference of various types. Depending on the model, thermostats can be responsible for the temperature of the floor heating, the air, or both at the same time. In the latter case, they are two-level and equipped with two types of sensors. Such thermostats are more effective at saving energy because they receive information about both the state heating elements, and about the ambient temperature. They turn off the system when any of the sensors reaches the required values.

Thermostats are also controlled by infrared devices. Their advantage lies in the installation method. Such temperature sensors can be mounted at a considerable distance from the regulators and used to control the entire heating system.

Connecting such devices is advisable in bathrooms, saunas and similar rooms with high humidity. In this case, the heated floor sensor will be located inside, and the thermostat, to avoid damage, will be located in a dry place.

Tips for choosing

The use of internal sensors is justified in situations where underfloor heating systems are not the only source of heating. Otherwise, it will be necessary to install an additional external device.

Before purchasing a thermostat, you should:

1. Focus on power. Check the compatibility of the regulator with a particular type of floor. It happens that the parameters of the latter are higher than the capabilities of thermostats offered by stores. In such situations, it is necessary to connect a magnetic starter, which protects the device from overloads.

2. Decide on the set of desired functions. They will allow you to more effectively configure your floor heating system and increase efficiency.

3. Pay attention to the clarity and simplicity of the interface if there are children and elderly family members in the house.

4. Check the connection method. There are thermostats that are attached directly to the wall or mounted in a panel. It is recommended to give preference to the model that fits better into the interior of the room.

5. Ask the seller about additional features of the regulator. For example, if you have heated floors in several rooms, you can use a dual-zone device that can provide temperature control in both systems.

6. Determine the feasibility of purchasing a programmable model if there are small children in the house. Such a thermostat is a technically complex device. Mechanical type much stronger and does not cause much interest among children.

7. If the floor covering is laminate, it is better to buy a digital controller. It will allow you to more accurately set the temperature and protect the material from overheating.

Installation nuances

The future location of the thermostat is determined based on the power of the floor and the device. If it is connected directly to the panel, you will need a two-kilowatt circuit breaker. However, more often the device is connected to a power outlet. At the same time, the number of devices that it services is calculated. As a rule, the thermostat is placed at a height of 80-90 cm. When using air sensors, installation must be carried out in accordance with the attached instructions. Or read the recommendations on the manufacturer's website.

A floor sensor, previously placed in a hose, is installed 50-60 cm from the place where the thermostat is located. This will protect the device from damage and make it easy to replace it in case of failure. There are ways to check the temperature sensor for a heated floor to ensure it is working properly. First, you can use a multimeter for active resistance. In addition, many digital thermostats display information about sensor failure on monitors.

Installation procedure:

1. Assemble the junction box (if there is a non-mounted thermostat).

2. The floor and wall are being chipped.

3. Electrical wires are connected to the box, and the voltage supply is checked using a tester.

4. Then a cable is connected to the regulator through a corrugated hose and a groove.

5. Following the diagram above, the wires are connected.

6. The thermostat is installed in place.

7. Secured outer panel and regulator cover.

Before starting operation, it is necessary to check the operation of the heated floor. This requires:

• set the temperature to minimum;
• turn on the power supply;
• using the toggle switch, start the heating;
• Smoothly changing modes, make sure there is a click accompanying the connection of the heating elements.

As can be seen from the description, installation of the system is simple. Many people can do it. However, to be more confident that the installation is correct, it is better to entrust the connection to specialists.

Prices

To help you navigate the prices of thermostats, an overview table is provided below.

If you are planning to install a heated floor with your own hands, then you need to get all the necessary information about temperature sensors first.

The temperature sensor is a mandatory element for optimal performance electric heated floor. In addition to temperature control, it helps reduce energy costs.

Product Description

A heated floor sensor is a copper wire protected by a special bulb that detects the temperature of the air or floor and then transmits this data to the thermostat. A plus is that the length of the wire can be adjusted - it is possible to reduce the wire or increase it to a maximum of 50 meters.

As the floor temperature increases, the sensor resistance becomes less. The thermostat, having received information from the temperature sensor, begins to react and either turns on or turns off the heated floor, taking into account the set temperature. Maintaining a certain temperature occurs as follows: when the desired setpoint is reached, the system turns off, and as soon as a drop of half a degree occurs, the heating starts working again.

If the sensor breaks down, it should be completely replaced. The main thing is that the replacement process occurs without errors, otherwise the system’s response to a drop in temperature deteriorates, and the interval before the floor turns on can reach 5 degrees.

Sensor selection

When choosing a heated floor sensor, which can be sold separately or complete with a thermostat, it is worth considering some factors:

1. Sensor type. It is necessary to select a sensor specifically for heated floors. There are other types, the readings of which are greatly influenced by drafts and direct sunlight. As a result, the device will record the temperature of the air, not the floor. There are options for measuring both;
2. Installation method.

There are only a few types of sensors:

• The limiter sensor mainly works for maximum or minimum temperature, that is, it does not allow the surface to cool or heat up to a certain level. It is usually used when installing cable electric underfloor heating. The limit sensor is installed in the insulating pipe.
• Sensors with thermostats are standard and programmable and are sold together with an underfloor heating system.

Many people believe that installing a thermostat and a heat sensor is not at all necessary. But unfortunately, in the absence of such devices, it will be impossible to control the heating level. Besides long work underfloor heating leads to excessive energy consumption. In addition, there are a number of floor coverings that cannot withstand overheating. For example, the temperature of carpet and laminate should not exceed 30 °C. Otherwise, the material will deform and begin to release substances harmful to human health.

A graph clearly illustrating the operation of a heated floor. As soon as the floor temperature drops to the set point, the sensor gives a signal to the thermostat, which turns on the heating. Having reached the upper temperature setpoint, the sensor-thermostat-heated floor chain is triggered again and the heating is turned off

An important point is that manufacturers of “warm floor” systems do not provide a guarantee for their products if a temperature sensor and temperature controller are not used.

How to install?

The temperature sensor is mounted next to the thermostat at a distance of 50 cm from the nearest wall. It records temperature changes, sends a signal to the thermostat, and it then adjusts the temperature of the underfloor heating. Therefore, it is very important to correctly install and connect the sensor, because the entire chain of further actions of the device is determined from it. The installation of a temperature sensor depends on the type of floor covering.

Sensor and thermostat installation diagram

The sensor for linoleum, parquet, laminate or carpet is a small cylinder that is attached to the end of the cable. It is placed in a corrugated tube with a plug at the end, which is fixed in the floor.

Sensors for hard surfaces, such as tiles, are protected by a special gel shell. It softens mechanical shocks.

The sensor can be installed in a groove or on the floor surface; it is placed strictly between the heating conductors of underfloor heating cables

The sensor for a warm floor must be installed between the heating cores. You can secure it with mounting tape. It is placed in a corrugation and sealed. One end should be near the heating core, and the other should be directed towards the thermostat. After which you can proceed to the connection.

How to connect?

There are two ways to connect a heated floor:

1. Straight. The thermostat and heating cable are combined.
2. Using a junction box. The cable runs to this box, and then to the heating circuit.

Automatic switches are installed in the electrical panel, and a distribution box is attached to the wall, to which the wires from the panel are supplied. A groove is laid from the box to the floor, two tubes will be located in it: in one there is a heating cable line, in the other there is a temperature sensor. After this, you can test the entire system by measuring the resistance. If the system is working properly, the floor covering or screed is laid.

Connection diagram for a heated floor through a distribution box

The main reason for the failure of a “warm floor” system is a breakdown of the thermostat. For diagnostics, it is necessary to measure the resistance between the cable cores. The exact resistance value is indicated in the thermostat instructions, but usually it is in the range of 5-30 kOhm. If the resistance values ​​differ greatly from the nameplate values, then there is no point in repairing the thermostat and it is better to completely replace it. To do this, you need to write down the model and contact a specialized organization for the sale and repair of such products. It is advisable that the sensor and thermostat be from the same manufacturer. Self-replacement only possible if the temperature sensor can be removed. If it is built in tightly, then you will have to resort to the help of specialists.

Do not forget that working with a heated floor sensor implies compliance with safety precautions. Before proceeding with the installation and connection of the sensor and temperature controller, the apartment should be de-energized. In addition, you need to know the basic basics of electrical engineering. If you are not confident in your abilities, it is better to entrust such an important matter to a professional.

Heated floor sensor - instructions for installing a temperature sensor for a heated floor

Heated floor temperature sensor: principle of operation, how to choose, step-by-step instructions for installing and connecting a heated floor sensor.

How to install a heated floor temperature sensor?

Design and purpose of a temperature sensor

So, the temperature sensor for a heated floor system is a thermistor protected by a glass bulb, and also has a copper conductor about 3 meters long for connection to the thermostat. In addition to the glass bulb for tile floors, the temperature sensor itself is also protected by a gel shell. The conductor is insulated with high-quality PVC (polyvinyl chloride) to protect against external influence and damage. The length of the conductor can be increased, and naturally, reduced, up to 50 meters, the main thing is that there is an undamaged sensor at the end of the conductor.

To easily replace it in the future, it is recommended to place this design into a metal-plastic tube, even if the manufacturer included a plastic corrugation with a diameter of 16 mm. The metal-plastic pipe has a smoother inner surface therefore, it is much easier to remove and install, as well as connect a new temperature sensor in case of failure. These types of temperature sensors are installed in solid floor coverings(under tiles or porcelain stoneware).

The principle of operation of the temperature sensor is very simple; when the temperature changes, its resistance changes, thereby giving a signal to the thermostat to turn on or off the heated floor system from 220 V, the most common network in everyday life.

Installation sequence

Let's move on directly to the installation of the heated floor and temperature sensor. First you need to determine the location of the thermostat, which will be located outside. It is most often located at a height of about 1 meter from the floor. Its mounting is similar to a regular socket.

Then you need to make grooves or grooves for laying two plastic pipes. One for the power wire leading to the heating element, the other for the electrical wiring of the sensor. The tube for the temperature sensor will be located on the floor. Such a gasket will make it possible to carry out renovation work, at least by replacing control elements. It is not possible to completely replace the heating element if it is installed in a screed. It is important that when laying a pipe or cable corrugation there are as few bends and turns as possible. This will simplify the replacement of a failed temperature sensor in the future.

The next step is thermal insulation, it is performed for different types heating elements individually, for example, for a heating cable it is used as a damper tape or other insulation, the thickness of which is at least 1.5–2 cm. After this, the heating element is installed and fastened with the wires connected to the thermostat box.

Installing and connecting a heated floor temperature sensor has its own subtleties. In order to prevent solution from getting inside the tube where the sensor is located, its end on the floor is securely sealed with electrical tape or tape. It is not recommended to connect the entire system through an outlet; it is better to supply power from a circuit breaker and through a contactor (starter).

The temperature sensor should be installed at a distance of 0.5 to 1 meter from the wall on which the thermostat is installed, and also exactly in the middle between two adjacent turns of the heating cable. After installation, it is recommended to secure the temperature sensor with mounting tape or foil tape.

If a film heated floor is being laid, the temperature sensor must be installed under the heater sheet, as shown in the photo below. Please note that thermal insulation must be laid under the temperature sensor, otherwise the heating system will not be effective.

Important point! The location of the temperature sensor should be selected so that it is away from other heating sources. Otherwise, errors will occur and the warm floor will not work as it should.

The connection diagram for the heated floor temperature sensor is as follows:

Before making a screed, you need to check the functionality of the heated floor and the temperature sensor itself. As a rule, the resistance of both elements is measured. The system is considered operational if the resistance differs by no more than 10% from the passport data.

In order for the assembled circuit to be as safe as possible, it is recommended that in rooms where electric floor heating is carried out, protective shutdown devices are installed, which, in the event of a breakdown, will disconnect the circuit from the voltage, thereby protecting a person from falling under electrical potential. In damp areas this can be deadly.

Selecting a thermostat

I would also like to touch upon the thermostat itself, which plays a very important key role in this heating system. There are the following types of temperature controllers for heated floors:

• Electromechanical. The clarity of such adjustment is approximate, so achieving a specific set temperature is quite problematic. The main advantage of such a device is its low price.
• Electronic. The set value is set using touch buttons and has fairly clear settings and the ability to set the temperature limit down to one degree.
• Programmable electronic. By installing such an element, you can not only regulate the temperature in the room, but also turn on the heating according to a schedule, or only when there is a person in the room.

By the way, some thermostats already have a built-in sensor, which makes it possible to control not only the temperature of the floor, but also the air in the room as a whole.

As a result, I would like to remind you about the rules for working with electrical equipment; all connection work is carried out with the power turned off. At the same time, it is necessary to ensure that no one, except the person performing this work, accidentally supplies voltage dangerous to human health and life. This is where our technology for installing a heated floor temperature sensor with your own hands ends. We hope the information provided was useful to you!

Installing a heated floor temperature sensor

How to install a heated floor temperature sensor. Diagram for connecting the temperature sensor to the network. Installation errors, which are demonstrated in the video example.

Installation and connection of a heated floor temperature sensor

A warm floor sensor is a plate or rod, the body of which is soldered from two metals. A distinctive property of such bimetallic conductors is their unique abilities - some produce electrical signals, the magnitude of which depends on the temperature of the environment in which the conductors are placed; others are able to take a certain shape under different temperature conditions.

The features of bimetals are used by industry to create various thermostats - devices that allow you to automate the operation of electric heating systems.

Features and benefits of use

The operating principle of each of these devices forms the basis for the creation of thermostats - mechanisms that turn on and off an electrical circuit depending on the state of the sensor.

In systems that heat floors to a given temperature, sensors are used that are distinguished by many parameters. But the biggest difference between them is the operating principle.

The first type of devices are electromechanical switches that physically close and open circuit contacts. Their working element is a bimetallic curved plate, the curvature of which depends on temperature. When the circuit is disconnected, the plate bends until it touches the opposite contact. When heated, the conductor straightens and the connection is interrupted.

The advantages of a thermostat that uses an electromechanical temperature sensor are simplicity, reliability and affordable cost. Such a device is easy to replace or repair with your own hands. In addition, electromechanical sensors are universal - they depend little on the model of the heating circuit.

The disadvantage of such a device is that adjustment must be done manually. The system is not able to respond to ambient temperature.

The second type of temperature sensor for underfloor heating uses an element capable of generating an electrical signal. The signal power depends on the temperature of the medium in which the bimetallic rod is placed. The pulse is sent to the electronic thermostat unit, which regulates the supply of electricity.

The thermostat is equipped sensory system control, its interface contains a digital screen on which information about operating parameters is displayed. Sensors of this type make it possible to set precise temperature values, and the unit maintains the required level independently.

The most complex thermostats are programmable. This class of devices provides advanced control capabilities for the temperature regime at home: with their help, you can set climate parameters - from the screen of a computer or smartphone, change them remotely using wireless communication, program the operating mode depending on the presence of people in the house, and so on.

The advantages of different thermoregulatory systems are manifested in different conditions. The use of devices with an electromechanical operating principle is justified in isolated rooms in which a person spends a short time but visits them regularly, for example, a bathroom or kitchen. Programmers are best placed in residential areas - bedrooms and living rooms.

Types and types of devices with sensors

Temperature regulators of the electromechanical type are often overhead - they can be built into electrical distribution panels. The advantage of this scheme is that the devices can be easily connected to residual current devices.

The sensor for a warm floor can be mounted directly in the heating circuit - as part of a water or electrical cable circuit. Temperature sensor - device small size, equipped with a cable for transmitting an electrical signal - can be remote or stationary. The remote device is simply placed between the heating wires.

Installation of the device in a concrete screed is carried out using additional protective covers made from a piece of corrugated pipe. The device must be placed in such a way as to ensure access to it. If the floor heating circuit is film type, the sensor is placed in a more rigid metal-plastic housing. In this case rational decision During installation, the walls and floors will be grooved.

When choosing systems that control space heating mechanisms, they often focus on devices that control temperature atmospheric air. They allow you to create a stable microclimate in the apartment and maintain it at a given level without human intervention. Temperature regulators of this type can work with several sensors installed in different rooms.

For thermoregulation to be effective, the temperature sensor must be located at an optimal height away from heating devices and devices that produce heat. If possible, the device should be protected from sunlight and drafts.

Disadvantages of using atmospheric sensors:

1. This method of regulation is irrational if the floors are covered with linoleum or parquet - materials that should not be subject to significant thermal effects.
2. The heat exchange in the room must be completely balanced, otherwise the heating elements will operate in a delayed mode, for example, a sudden entry of cold air into the room will lead to an overload of an already heated circuit.

Installation of temperature sensors

The installation of a heated floor sensor is carried out taking into account safety rules. Unauthorized access to it should be limited, first of all, for young children. The recommended installation height is 1.7 m. The manufacturer supplies thermostats that are designed for hidden and open wiring. Devices of the first type must be buried in the wall when installed.

1. A half-hole is made in the wall partition: its depth should be sufficient to install the mounting box;
2. From the recess downwards and in the floor screed, a channel (groove) is punched for laying cables and signal wires;
3. A channel for input wires is made from the seat up to the switchboard.
4. The signal wires and power cable are packaged in a plastic protective hose: its diameter is chosen so that the device can be removed if necessary. The bend of the tube should be sufficiently rounded (from 5 cm) - over time it should not become an obstacle to the possible advancement of the device and cable.
5. The sensor is placed at an equidistant distance from all thermal elements and no closer than 0.5 m from the wall partition.

Connecting a temperature sensor

Connecting a heated floor sensor is a multi-operational process, the observance of which requires care. Before connecting the sensor to the power supply, it is necessary to perform the following preparatory work:

1. Disconnect the network;
2. In the distribution box on the DIN rail, secure an additional protective disconnecting device and a circuit breaker. Externally, the devices are similar, but their operating principles are different. The first device is designed to turn off the voltage in the event of damage to the insulation and the appearance of a “breakdown” on the walls. The second is necessary to disconnect the network in case of a short circuit;
3. Lay a three-core cable from the junction box to the sensor installation site.

How to connect a heated floor sensor? Connect the wires in the junction box as follows:

• black: to the intermediate circuit breaker (bottom), from it to the RCD (bottom), then to the input circuit breaker;
• light blue (blue): to the RCD (bottom), then to the block with neutral wires;
• yellow with a green stripe - to the earth bus.

In the wiring box you need to connect the wires to the thermostat in accordance with the diagram. The connection procedure and diagram are determined by the instructions.

All devices are equipped with a standard block with six terminals, which are marked accordingly. Each connector has a mark that indicates:

• L: “phase wire” from the network;
• N: “neutral” wire from the network;
• L1: “phase wire” to the thermal circuit;
• N1: “zero” wire to the thermal circuit;
• PE: grounding bus.

Please note:

1. The blocks of some thermostats may not have a terminal for connecting the “ground wire”. In this case, the corresponding wires are connected directly - using a suitable connector or bolted connection;
2. The marking of the wires that are connected to the working elements of the heater may have a different form, for example: “L” and “N” are connected by a jumper with a resistor icon (rectangle).

Replacing the temperature sensor

Repair of electric cable-type underfloor heating is often associated with failure of the temperature sensor, thermostat or connecting devices. There are times when heater elements stop functioning. To find the cause, it is necessary to conduct a diagnosis.

Experts say there are only two faults electrical devices: there is no contact where there should be, and there is contact where there should not be. Both faults are detected using a tester.

Before starting work, the power is disconnected from the network.

Testing begins with the input wires. Before the “dialing” begins, the thermostat housing is disassembled. In most cases, this requires prying off the adjusting gear with two screwdrivers to free access to the screw connection. However, there are other options - clips or latches.

After removing the thermostat cover, access to the contact group opens.

The general connection diagram for the sensor is as follows: it is connected in series with the power and control units.

First, it is determined whether the input circuit is working. To do this, turn on the power and use a tester to check the presence of voltage between the wires connected to the “L” and “N” terminals. If there is no power signal, it means that some switch is not working, in which case the functionality of all devices that are located in the circuit upstream of the thermostat is sequentially checked. It may be necessary to repair another device - a block or a breaker.

If there is potential at the input contacts, you need to check the presence of voltage at the output. To do this, disconnect the wires from the thermostat (with the devices de-energized) from the thermal circuit. If, when the supply is turned on, there is no signal at the output contacts of the thermostat, it means that the sensor or control unit is broken.

Then the resistance of the sensor is checked - its value should be in the range of 5-45 kOhm. To measure this value you need an ohmmeter. The exact parameters that the sensor characteristics must correspond to are determined by the instructions. The temperature sensor cannot be repaired; if it malfunctions, it must be replaced. Installation of a new sensor is possible only with the purchase of a new thermostat. Repair of the thermostat assembly is carried out in specialized workshops.

The possibility of replacing the temperature sensor depends on compliance with the rules for its installation. If it is not possible to remove the device, the entire floor heating circuit may need to be repaired. With a careful approach to the work and patience, it is quite possible to change the sensors that regulate the temperature, even with your own hands.

Heated floor sensor: how to check, install and connect

The heated floor sensor allows you to flexibly adjust the temperature in rooms with heated floors. Its installation and connections are quite simple if you have even a little knowledge of electronics.

How to install a heated floor sensor and thermostat

A sensor for a warm floor and a thermostat allow you to control the entire heating process. It is with their help that the optimal thermal regime for the heated floor covering is created.

Installing these items is easy. We will tell you how to do this below. But first, let's briefly describe these products. This will help to do right choice when purchasing them.

Thermostat and sensor

Sensors and thermostats for heated floors

Selecting a thermostat

To make the right purchase, you will have to take into account the features of different types of such devices.

They, in turn, are as follows:

• Electronic-mechanical - similar to those installed in irons. With their help it is impossible to set a specific temperature value. By turning the wheel, its approximate value is set here, which is then maintained. The advantages of such a product are its simplicity and affordable price;

• Electronic - in their principle of operation they are similar to the previous ones. The difference is that they can be used to set the exact temperature degree. In addition, their design does not use a wheel, but buttons or a touch screen;

Pictured is an electronic regulator.

• Programmable - can not only maintain a given temperature, but also perform other actions. For example, they are able to turn off the heating in the absence of people. Or, turn on at a certain time and heat the room when the residents arrive. Despite their high cost, thanks to energy savings, these devices pay for themselves quite quickly.

Do not install programmable controls in small rooms such as a bathroom or closet.

After all, they have to be heated quickly and at unplanned times.

For such premises it is better to use electronic-mechanical devices.

Sensor selection

Typically, floor heating sensors are sold complete with thermostats. This is very convenient because it eliminates the need self-selection suitable elements.

In general, it should be noted that these devices can be internal or external. In the first case, the sensor is built into the heated surface and measures its temperature. The second sample is installed outside the coating and measures the heating of the surrounding air.

It is also possible that both types of devices are used. This is usually found in programmable devices, such as the SE 200 thermostat from the Teplolux company.

Thermostat SE 200 with two temperature sensors

If an electric heating system is used, it would be a good idea to install a water sensor on the floor.

If a water main breaks, it will cut off the liquid supply.

This will not only save your home from the threat of flooding, but will also prevent possible failure of the floor heating structure.

Installation of sensor and thermostat

General installation diagram

Warm electric floors can be installed in the following ways:

• using a junction box - in this case the cable is connected to the regulator through a junction box;
• direct connection - in this case, the heating cable is connected directly to the thermostat. We will now consider this option.

Installation of elements begins with preparing recesses in the wall for laying corrugated pipes and installing the regulator. For this we use a hammer drill.

A mounting box should be placed in the recess for installing the thermostat. If for its operation the voltage is supplied not from batteries, but from a 220V network, then you will have to connect the appropriate wires to it.

The second stage of our work is the installation of a heated floor sensor. It is carried out as follows. We take the sensor and place it in the corrugated pipe that comes with the floor.

Place the device in the pipe

In this case, we place the device near the end of the tube. On the other side there will be a connecting wire coming out.

The first end of the pipe must be tightly sealed to prevent cement mortar from getting into it.

You can do this in the following ways:

• wrap with electrical tape;
• flatten with pliers and attach to the floor using a self-tapping screw;
• use heat shrink tubing and a hair dryer.

After this, we continue installing the heated floor sensor. I put the phone down on the floor. Moreover, we do this in such a way that the radius of its bend is at least 5 cm. The distance from the wall to the place where the sensor is located should be 50-60 cm.

Maintain the required distance

The device should be placed in the tube so that it is freely located there.

This will allow you to easily replace it if necessary.

After this, using mounting tape we secure the tube between the turns of the cable. We place it so that it is at an equidistant distance from the turns of the wire.

We place the second end of the corrugated pipe in a pre-prepared channel and bring it out into the thermostat installation box. Then, the groove with corrugation can be covered with cement mortar.

Insert the tube into the mounting block

Now you need to connect the cable and sensor leads to the thermostat. The instructions included with the kit will tell you how to do this correctly.

Typically it looks like this:

• a temperature sensor is connected to terminals No. 1 and No. 2;
• the heating cable leads are connected to connectors No. 3 and No. 4;
• terminals No. 5 and No. 6 are used to connect home electrical wiring wires.

Upon completion of the above work, it is necessary to check the entire system for operability. To do this, turn it on for about 1 minute. If everything is in order and connected correctly, the LED on the thermostat will light up and the heating cable will become warm.

The power can now be turned off. Installation is complete. After it, you should do the filling yourself cement-sand screed. After 28 days you can start using the underfloor heating system.

Draw the layout of the cable and sensors.

It must indicate the specific location of their location, indicating the distances from the walls.

This may be useful in the future when carrying out repair work.

Sensors for heated floors together with a thermostat will help ensure the appropriate thermal conditions in the room. In addition, they will make the process of controlling heating more convenient.

You can install an electronic-mechanical, electronic or programmable thermostat. The choice of one type or another will depend on the area of ​​the room and the volume of tasks that this device must solve. In most cases, you won’t have to select a sensor, since it usually comes complete with a thermostat.

Connecting a heated floor sensor and a thermostat is not very difficult and can be done on your own. You could read about this in detail above.

Thermal elements of a heated floor do not come into contact with the air they heat, so the temperature in the room is controlled by an external device - a thermostat. The amount of electricity consumption depends on its functionality. Agree, for an informed purchase it is worth understanding the characteristics and capabilities of the device.

We will tell you how to buy the most suitable thermostat for your underfloor heating. The article we have presented describes its varieties, which differ in the type of control, the type of temperature-fixing device and the method of installation. Tips to make your choice easier optimal model.

The thermostat is designed to control the operation of the underfloor heating system (WHS). It consists of a control device and one or more sensors. Information from them is taken into account when turning heat mats on and off.

Thanks to the operation of the device, an even temperature is maintained in the rooms and energy consumption is minimized.

The rhythmic switching on of heated floor heating mats allows you to save half of the electricity, which pays for the cost of the thermostat in a few months

Thermostats are easy to use and even teenagers can use them. In this case, the operating mode of the STP can be changed several times a day without fear of breakdown or premature failure of the equipment.

Minimum temperature can be configured separately for each room. In addition, some models allow programming of the device’s operating mode during the day.

Types of devices by type of control

The operation of the STP is regulated by a special device, which is usually hung on the wall. It has standard dimensions key switch and can be equipped with a mechanical, electronic or programmable interface.

Mechanical without electronics

A mechanical thermostat does not include electronic components in its design. Electric wires they go to the STP directly through the device, which adds problems during its installation.

Mechanically, the thermostat usually has a limit switch. It allows you to quickly turn on/off the device without having to change temperature settings

The function of a temperature sensor in a mechanical regulator is usually performed by a bimetallic plate, which, when cold, closes the contacts of the heating mats. As the temperature in the room increases, it bends and disconnects the electrical circuit, as a result, heat generation stops.

The regulation interface is represented by a wheel, by rotating which you can adjust the temperature in the room.

This device design has its advantages:

1. Low price.
2. Easy to use.
3. Ability to work at low temperatures.
4. Reliability.
5. Independence from voltage surges.
6. Long service life.
7. Automatic switching on after a power outage.

The simplicity of a mechanical thermostat also causes its disadvantages, which can be critical:

1. Minimal functionality.
2. Lack of remote control capability.
3. Large error.
4. The presence of clicks when bending the bimetallic plate.

Despite their simplicity, mechanical thermostats have a strong hold on the consumer market due to their high reliability, simplicity and interchangeability.

With electronic mechanism

The appearance of electronic thermostats may not differ from mechanical devices. The main difference lies in the internal filling of the device.

Mobile thermostat units are usually battery-powered, so their displays are not backlit. Setting up such devices in a dark room is difficult.

Electronic floor heating controllers consist of the following components:

1. Frame.
2. Control microcircuit.
3. Built-in or external temperature sensor.
4. Electronic key for turning on and off the power supply to heating mats.

Setting the temperature in electronic thermostats can be done using the touch screen, buttons, adjustment wheel, or a combination of these methods.

Some models support multi-zone temperature control, in which several isolated heated floor zones with their own sensors are independently connected to the control microcircuit.

The advantages of electronic devices include:

1. Possibility of installing a remote temperature sensor in any location in the room.
2. Availability of a display showing the current and set temperature.
3. Possibility of multi-zone heating control.
4. Temperature sensor accuracy up to fractions of a degree.
5. Indication in case of error or breakdown.
6. Possibility of completing with an external remote control unit.

The disadvantages of an electronic thermostat are mainly due to the presence of a microcircuit.

Thermostat models are not tied to specific manufacturers. During installation, the devices can be combined with heating mats and sensors from various companies

The disadvantages include the following characteristics:

1. Dependence of the stability of the control microcircuit on voltage drops.
2. Failures in settings during a short-term power outage.
3. Higher price than mechanical devices.

Mechanical thermostats are only 15-25% cheaper than their electronic counterparts, therefore, in the absence of voltage drops in the network, the choice between these two types of devices is determined mainly by their appearance.

Great looking luminous displays are often the main motivating factor when purchasing a particular thermostat model.

Programmable electronic devices

The main difference between programmable thermostats and conventional electronic devices is the expanded functionality of the control microcircuit. This type of device allows you to set different temperatures in the rooms depending on the time of day.

As a result, users benefit greatly from energy savings by reducing the heating of the air in an empty home.

The cost of a programmable thermostat directly depends on the quality of the display and the number of parameters that the device operates in its operation.

Programmable thermostats may also have a remote control function from a smartphone via Wi-Fi.

The disadvantages of such devices include the high cost and difficulty of setting up in the absence of skills in handling the equipment. Otherwise, the pros and cons of programmable thermostats are the same as conventional electronic ones.

With remote control unit

In electronic and programmable thermostats, internal components can be divided into two blocks: main and mobile. Electrical cables are connected to the main box and wired temperature sensors are connected. It can be located in any remote location of the room, which facilitates installation work.

Some manufacturers of programmable thermostats produce their own applications for smartphones, by installing which you can configure the equipment from your gadget

A battery-powered mobile unit is used as a control panel. It can lie on a table or hang on the wall. Additionally, the consoles can be equipped with external temperature sensors that measure the ambient air temperature. Such devices are convenient because they allow you to hide the adjustment mechanism from small children.

Types of temperature sensors for underfloor heating systems

The operating mode of STP heating elements directly depends on the correct temperature measurement by temperature sensors. They can be built into the body of the control box or placed remotely.

Thermal sensors come in four types:

1. To determine air temperature.
2. Infrared, measuring the heating of the floor surface from a distance.
3. To determine the temperature of the floor surface by contact method.
4. Combined.

The air heating sensor is usually built into the thermostat or its mobile unit. It is used when the heated floor is the main heating system. The main requirement for its location is the presence of natural air circulation around the device.

The tips of temperature sensors should be made of materials that conduct heat well, then the speed of the thermostat’s response to excess heat will be higher

Infrared floor temperature meters can be built into the thermostat housing or placed as a separate unit. The main requirement for their installation is that there are no obstacles between the sensor and the floor. The distance between the device and the surface to be analyzed must be at least 30 cm.

Contact-type temperature sensors look like a long wire with a thickening at the end. On the one hand, they are connected to the thermostat unit, and on the other, they are placed in a special long corrugated pipe under the floor. This installation feature makes it easy to replace a broken sensor with a new one.

The advantage of underground placement is the possibility of multi-zone control of floor temperature within one room. Typically, such sensors are installed as part of an additional heating system.

Several sensors can be connected to the thermostat, but this scheme is used mainly within the framework of an integral set of equipment.

Rules for installing a thermostat

Electrical cables and wiring from temperature sensors must be connected to the thermostat hung on the wall. To do this, appropriate grooves are made in the slab - grooves. In them the wires are laid to electrical panel and to the floor.

The floor temperature sensor must be as far from each other as possible from adjacent heating elements, otherwise when they are turned on, it will immediately trigger and disconnect the electrical circuit

If the equipment is installed in a room with high-quality interior decoration, then you can use overhead devices and run cables over the walls in boxes.

1. It is better to place the adjusting device at a distance of 40-170 cm from the floor, unless otherwise provided in the instructions. If you have a mobile control panel, the main box can be installed in any convenient place.
2. The main functions of the floor temperature sensor are to prevent overheating of the floor covering and foot comfort, but not to control the temperature of the air in the room.
3. In damp rooms It is allowed to use thermostats with appropriate protection against water ingress.
4. When the device is built into a wall, a mounting box made of non-combustible materials is used.
5. Wires from the regulator to underfloor heating heaters with a power of more than 1 kW must be routed in hollow heat-resistant tubes.
6. The floor temperature sensor should be located between the heating elements and at least 50 cm from the walls.
7. When turning on the device for the first time, it is necessary to take into account the minimum operating temperature specified in the instructions.
8. Wire connections to the thermostat terminals must be made exclusively according to the diagram specified in the manual.
9. Installation of the thermostat begins only after the heating elements are finally laid on the floor in order to correctly calculate the length of the wires.
10. When filling the floor with solution, it is necessary to well insulate the end of the tube with the temperature sensor.
11. Before pouring the solution onto the floor, it is necessary to check the functionality of all elements of the system.
12. Heating mats must be grounded, and an RCD is installed in front of the thermostat.

Compliance with these rules will protect residents from electric shock, the house from fire, and equipment from premature failure.

When purchasing a thermostat, you need to know certain nuances in order to pay only for required functions and ensure the longevity of the operation and the device itself.

When choosing a thermostat, you should pay attention to the quality of the plastic case. If the manufacturer saves on this, then it is worth thinking about the reliability of internal components

These selection features include the following rules:

1. For heating small rooms, an inexpensive mechanical or electronic thermostat with an internal air temperature sensor is suitable.
2. It makes sense to buy a programmable thermostat if you need multi-zone temperature control, as well as to save energy when there are no residents at home during the daytime.
3. The thermostat must correspond to the maximum power of the heating elements with a margin of 25-30% in case of operation at reduced voltage.
4. For houses with wooden interior decoration, only overhead thermostat boxes are suitable.

Also, when choosing a device, it is necessary to take into account its design.

Existing the lineup allows you to buy not only reliable equipment, but also a thermostat that will fit perfectly into the interior of the room.

Video #3. Installation of a temperature sensor in the floor:

Analysis of various thermostats allows us to say that their maximum functionality is not always justified from both a financial and operational point of view. Therefore, this equipment must be selected for each STP separately.

How did you choose, attach and connect the thermostat for the underfloor heating system? Share what became the decisive landmark for you? Please leave comments in the block below, ask questions, publish useful recommendations and photos related to the topic of the article.

Underfloor heating systems are very popular, and this is understandable, because they significantly improve indoor comfort and make the home more cozy. And in order to maintain and optimally regulate this comfort, you need to be able to adjust the temperature of the floors. For this, a thermostat is used, which must be installed when installing a heated floor.

The warm floor begins to perform its main function immediately after connecting to the power supply. However, working at full power, it will not last long and will significantly hit your pocket, spending too much energy. In addition, it will be too hot, which may not be very comfortable. To avoid all the troubles and ensure the most pleasant operating conditions for the heated floor, you need a temperature regulator.

Classification of thermostats

According to the operating principle

This classification is the most understandable and accessible. There are several types of thermostats:

It works on the same principle as the heating regulator of a regular iron. It is impossible to set any specific temperature value. The principle of operation of a mechanical regulator is as follows: its wheel rotates, being set to the desired position, the temperature of the floors changes and is maintained. Based on your feelings, you can lower or increase the temperature, setting it a little more precisely - in general, like in the shower. This type of regulator is the cheapest and simplest.

In its essence it is similar to mechanical, only regulation is carried out using keys or a touch screen. Another difference is the ability to set the exact temperature with an accuracy of up to tenths of a degree.

The most technologically advanced type. As the name implies, it allows you to store certain programs in the device’s memory that regulate the temperature as conditions require. For example, when there is no one at home, the regulator turns off the heating, turns it down at night, warms up the floor in advance before the owners arrive, etc.

By location

Based on this feature, there are only two obvious groups: regulators located inside the heated room or outside it, for example, in an electrical panel. Standard practice is to locate the floor heating thermostat in any place that is convenient for access, with the exception of bathrooms - electronic devices should not be installed in them.

Another limitation is power. A standard thermostat is designed for no more than 3 kW. As a result, you need to carefully correlate the number of sensors and their type with installed system heating If it exceeds the permissible power, you will have to install a dual-zone thermostat or two regulators for separate areas of the room.

Such two-zone regulators can also be used to adjust the temperature in two rooms at once, if the total power of floor heating systems does not exceed permissible limits.

By sensor type

It is worth noting that thermostats are compatible with different types of sensors. As standard, the device has only one temperature sensor that measures the temperature of the heated floor, which may often not be enough. In conditions where underfloor heating is the only heating system, a sophisticated room temperature control scheme may be required.

In this particular case, you can regulate the overall temperature, and not just the degree of heating of the heated floor, and then an air heating sensor will come in handy, which can also be connected to the thermostat.

There are cases when, on the contrary, precise adjustment of the temperature of the floor covering is necessary - for example, if flammable materials are used as finishing materials: wooden or laminated parquet, or linoleum. In this case, it is extremely dangerous to allow the coating to overheat above 26 degrees.

Thus, there are two types of thermostats:

• with built-in temperature sensor;
• compatible with outdoor sensors.

Installation of temperature sensors and regulators

The installation diagram of devices depends on the selected type. Usually you will need a niche in the wall into which the thermostat will fit. The heated floor system will be connected to it according to the instructions provided by the manufacturer.

Power can be provided either by connecting to a wall outlet or by connecting directly to the mains using a special wire.

Sensor installation

This issue should be treated with special attention, since it is through the sensors that the thermostat receives information about the temperature, and errors in their installation can lead to both incorrect readings, which will lead to a decrease in the efficiency of the system, and to complete inoperability of temperature regulation.

The basic underfloor heating system usually consists of the heating element itself, although there are options with a thermostat included.

The sensor and wires for the thermostat are passed through the corrugation and placed in a groove punched in the wall. This is necessary so that in the event of a malfunction, parts of the system can be replaced without breaking the wall. This tube will allow you to pull out all the wires even from completely filled concrete floors.

The temperature sensor should be located no further than one meter from the regulator, between the heating elements of the system.

There are no other requirements for the sensors, so the control device can be used with any type of heated floors, including those based on hot water heating.

It is important to keep in mind that heated floors and devices for regulating their temperature are complementary components of a single system, and only by working together will they ensure real comfort of living in the room and long-term, impeccable heating service. Thermostats cannot be neglected, especially since the variety of their types will allow you to choose suitable option for any person.

Thermal sensor for heated floors: classification and installation

It is through the temperature sensor that the thermostat receives information about the temperature, and errors in their installation can lead to incorrect readings.

Warm floors are gaining growing popularity as additional or main heating for apartments and private houses. Even if the owner does not have the opportunity to provide this useful system your entire home, you can heat only a small area, for example, in the bathroom. In this case, the costs will not be so high, and comfort during water procedures will increase noticeably. It is much more pleasant to stand barefoot on warm tiles than on cold tiles.

In addition, the bathroom, which is usually not included in the home heating system, will receive an additional source of air heating. Self-installation - great way reduce costs, but it is important to do all the work correctly. Special attention requires a thermostat for underfloor heating. It is not difficult to install it yourself, but you will need to carefully study the instructions.

How does a thermostat work?

The thermostat, as the name suggests, regulates the heating temperature of the heated floor. This electrical appliance, which needs to be connected, firstly, to the heating system and a temperature sensor, secondly, to the power supply. If the thermostat is connected correctly, it operates as follows:

• receives data from the temperature sensor about the current heating temperature;
• compares them with the specified value specified in the settings;
• turns off heating when the set temperature value is exceeded;
• turns on heating if the floor temperature is lower than specified in the settings.

The cycle is constantly repeated, which ensures uniform heating of the floor and room, as well as optimal consumption of thermal energy.

For residential premises, the floor heating temperature is usually set at about 26 degrees, and in kindergartens and other similar institutions 24 degrees is sufficient. The heating temperature readings are also affected by the type of floor covering.

Electrical systems laid under laminate usually operate at 27 degrees, but heated floors placed under parquet can heat up to 30 degrees. Excessive heating of the elements can lead to deformation of the floor covering and system failure.

What types of thermostats are there?

There are several types of modern thermostats designed specifically to work with electric floor heating systems. It is worth noting that underfloor heating is not always installed with water systems.

Sometimes owners prefer to adjust the heating manually. But for mats, cables or other electrical systems, a thermostat is required, since it is an effective way to save energy, as well as an opportunity to significantly increase the safety of using a heated floor. A water-heated floor rarely overheats, but electrical systems require a high degree of control.

There are both extremely simple models of thermostats and devices equipped with one or more additional functions. Among them it should be noted:

• The presence of a programmable timer that allows you to set different temperature conditions for different times of the day. As a result, the intensity of thermal energy consumption can be reduced for specific periods of time and full operation of the system can be restored the rest of the time.
• Built-in energy saving mode, which provides a significant reduction in heating temperature during periods of absence of residents in the house, which makes it possible to significantly reduce electricity bills.
• The presence of a limit sensor that allows you to pre-set heating temperature limit values ​​for specific air temperatures in the room, which prevents accidental overheating of system elements, as well as the floor surface.
• An intelligent programming function that allows you to almost arbitrarily, depending on the situation in a particular home, set the duration and mode of changing periods of saving and intensive heating.

It should be borne in mind that to install a heated floor in a small bathroom there is no need to purchase an expensive programmable model. In small areas, the simplest models successfully cope with the task of regulating the operation of a heated floor: electronic or even mechanical.

But on a large footage, i.e. in a spacious bathroom, it may make sense to install a more “advanced” thermostat to reduce electricity costs.

When choosing a thermostat, you should focus on the power and size of the heating system to which it will be connected. The power of a household thermostat for heated floors, as a rule, does not exceed three kilowatts. Although thermostats can vary significantly in type and feature set, the way they are connected usually does not differ significantly. Typically, thermal sensors are used with underfloor heating systems, which are located under the floor covering.

The thermostat can also be adjusted to read the air temperature in the room, but for this you need to carefully choose the location of the sensors, since their data can be distorted by a variety of factors: drafts, furniture position, household electrical appliances, etc.

Installation and connection procedure

For an experienced electrician, installing any thermostat is not particularly difficult. Regardless of the model, the manufacturer usually supplies the device detailed instructions. In addition, the connection diagram is usually located directly on the panel of the device.

But for a home craftsman who has difficulty understanding the specifics of an electrician’s work, the task may prove difficult to complete. Knowing the details and important nuances when installing a thermostat will help you avoid mistakes and the need to redo the entire job.

Preparing the device and installation site

The first thing you need to do before installing a thermostat is to study the instructions and recommendations provided by the manufacturer. It will usually tell you how to remove the front panel to make the connection. Remove the control panel carefully so as not to damage the device.

Then you need to prepare a place to install the thermostat. It is usually chosen when designing a heated floor system. It is recommended to place the device at a height of approximately 0.6-1.0 m from the floor. It is advisable to have electrical outlets nearby, which will make connecting the power supply much easier.

In a suitable place, you should make a niche in the wall, the dimensions of which allow you to install a mounting box for the thermostat into it. Alternative option is to mount the mounting box directly on the wall, but this solution does not look very good in the interior.

Connecting power supply and temperature sensor

First, power wires must be connected to the device. It is necessary to determine the wire with the phase. It is usually dark: black or brown. You can check the presence of voltage using a tester. The working wire with zero voltage is usually of blue color. The difference between zero and phase should be 220 V.

Color coding of cables greatly simplifies the process of installing the thermostat. Here are some useful information about this marking:

• phase wire is usually white, black or Brown and is marked with the letter L;
• the neutral wire is designated by the letter N, most often it is a blue wire;
• The ground wire is usually yellow or green (optionally yellow-green).

The process of connecting the thermostat to the electrical network and heating cable can be viewed more clearly using the diagram:

First you need to connect the power cable to the appropriate sockets. A phase wire, designated as L, is connected to contact 1. Wire N is connected to socket 2, i.e. zero. Then connect the contacts of the heating cable to sockets 3 and 4. The neutral wire (N) is connected to socket 3, and the phase wire (L) is connected to socket 4.

After this, connect the temperature sensor to the thermostat through sockets 6 and 7. At this stage, there is no need to observe any polarity.

After this, connect the temperature sensor. The sensor itself must be housed in a length of corrugated pipe and laid out in such a way as to transmit adequate temperature data. The temperature sensor wires are brought to the thermostat housing and connected to it.

Features of connecting a heating cable

The heating cable for underfloor heating can be two-core or single-core. In the first case, under the insulation there are two wires through which current flows, as well as another wire intended for grounding the device. The diagram below shows how to connect such a heating cable.

Brown and blue wires are conductive. The brown wire has voltage (phase), the blue wire has zero. The green color indicates the ground wire. The brown, blue and green wires are connected to sockets 3, 4, and 5 respectively.

When installing a thermostat of this type, you will need a special terminal for the ground wire. It is not always included in the delivery package, so you should check the availability of the terminal in advance or purchase required part before installing the device.

It is believed that connecting a two-core heating cable to a thermostat is easier than a single-core one, since the latter must be connected to the device on both sides.

Under the sheath of a single-core cable there are two wires. According to one of them comes electricity, the second is necessary for grounding the device. Typically the live wire is white and the ground wire is green. In the diagram you can see how to connect such a cable to the thermostat. A live wire is connected to sockets 3 and 4, and grounding is connected to socket 5.

The connection diagrams described above allow you to get a general idea of ​​how to connect the thermostat to the heated floor, temperature sensor and electrical network. However, when performing installation work in each specific case, you should pay attention to the design of the selected device and the features of the heated floor heating element.

In addition, it is necessary not only to follow the instructions of the device manufacturer, but also to adhere to safety regulations when carrying out electrical installation work.

Installing the device into the box

After this, the thermostat is installed in the installation box. You should act carefully so as not to damage individual elements of the device. The thermostat should fit into the box freely; it is not recommended to use force to install it.

Checking and setting

After this, all that remains is to check the correct position of the device using a level so that it stands level. If all operations are performed correctly, you can hang and secure the front panel with the control unit with screws.

After the thermostat is closed with the lid, you should turn on the machine and apply power to the device. Then check the power indicator on the control panel. If the thermostat is equipped with an LCD screen, the corresponding values ​​will appear on it.

IN simple models the presence of power supply can be indicated by a conventional diode indicator.

Another way to check the serviceability of a programmable thermostat and that it is connected correctly is to set the device to the minimum possible heating temperature, and then turn it on. Then you should set the maximum possible temperature and check that the heating circuit is closed, which will be indicated by a characteristic click.

The device must then be adjusted to the appropriate temperature data. If by this time the work on laying the heated floor is completely completed, and the concrete screed has already dried (in the case where its installation is provided for by the technology), you can test the operation of the heated floor and make sure that the thermostat is working correctly.

• set the time to turn the device on and off;
• set suitable temperature data;
• run the heated floor and monitor its operation throughout the day.

Modern thermostats, equipped with a large number of electronic components, must be installed very carefully and carefully. Such devices are very sensitive to voltage surges, and if the wires are connected incorrectly, the device can simply burn out. Therefore, if in any doubt, a novice electrician should consult a more experienced specialist.

To control modern heating systems capable of maintaining constant comfortable temperature, a thermostat is used for heated floors. Together with an external temperature sensor, it monitors and regulates not only the heating of the floors themselves, but also the air in a given space. Thermostats can be installed in each room where there are heated floors and regulate the degree of heating in each of them. Some models are equipped with touch controls, additional temperature sensors, and can be programmed for different temperature values ​​at certain times of the day or days of the week.

How to choose a thermostat for a heated floor

Normal operation of a heated floor is impossible without a thermostat, which allows you to save a significant amount of energy and Money. When performing the assigned tasks, this device only turns the heating on and off at a set period of time or in accordance with the readings of the thermometer. When choosing a thermostat, it is necessary to take into account its power, which must correspond to the power of the heated floor.

The creation of the most comfortable conditions in the room, as well as the safety of the floor covering, largely depends on the operation of the thermostat. If the temperature is too high, the floor covering may become deformed, crack and lose its quality. Therefore, which thermostat is best to choose for a heated floor is an important issue when installing heating systems.

Among the huge number of models and designs of thermostats, experts distinguish several main groups:

• Devices that provide an economical mode of operation, allowing to reduce energy consumption in the absence of owners. At this time, the heating power decreases by several degrees.
• Models with a programmable timer that allows you to set any time intervals during which the room will be heated at a given intensity. All commands from the timer are transmitted to the thermostat, which, in turn, maintains the required temperature level.
• There are highly intelligent designs where entire operating modes can be programmed and set, in which periods of heating and saving alternate. The command from the device goes directly to the heating element at a set time, depending on external factors and specified settings.
• Thermostats using a built-in limiter, which is a special sensor that protects the floor covering and the heating element itself from overheating. Such devices are most effective for laminate, which should not heat above 260C. Otherwise, the release of harmful toxic substances will begin.

The choice of thermostat for a particular room depends on its area. For a small room, a regular device without programming or installation will be sufficient. The use of more complex programmable devices is best suited for larger spaces. Most often in such cases, electronic thermostats with temperature sensors installed inside the floor are used.

Mechanical thermostat for heated floors

The simplest devices include room mechanical thermostats equipped with a panel manual control. This panel in most models is made in the form of a rotary regulator, around which there is a temperature scale. The device is turned on and off using a special key.

When deciding which thermostat to choose for a heated floor, it is necessary to take into account the lack of mechanical devices any electronics. These devices do not require electrical energy to operate, although many models have indicator lights on the panels that indicate the status of the heating process. Some designs are equipped with a mechanical timer that sets the operating time of heated floors at a certain time.

The air temperature in the room is measured by a special built-in temperature sensor for a heated floor thermostat, the operation of which is based on the properties of gases or bimetallic elements. Under the influence of the environment, they are able to change volume or shape. That is, when the desired temperature is reached, the electrical circuit begins to close or open. In this case, the temperature of the heating elements themselves is not controlled.

Thus, the mechanical regulating device is capable of maintaining desired temperature until it is turned off. If necessary, just turn on the thermostat again and wait for the heated floor elements to heat up.

Electronic thermostat for heated floors

The most widely used are non-programmable electronic thermostats, which allow you to control the temperature level with an accuracy of 0.5 degrees.

The liquid crystal display of the device displays the current and set floor temperature, as well as the room temperature. In addition, a special symbol appears on the screen when the heating system is on. Displayed periodically different kinds technical messages, symbols indicating malfunctions in the underfloor heating system. This function allows you to perform diagnostics in electronic thermostats. Direct control of the device is carried out by three small keys located on the external panel.

Power is supplied to the heating elements in the same way as with mechanical thermostats. It must be taken into account that electronic device can constantly change on and off cycles, saving about 30%. Its work will continue until the warm floors are forcibly turned off by the owners.

Programmable thermostat for heated floors

When heating large areas Energy savings are of great importance, especially when using heated floors. This problem is easily solved with the help of a programmable thermostat, used not only with cable, but also with film systems.

The operation of programmable thermostats is carried out according to the same schemes as in conventional electronic devices. The fundamental difference is the ability to configure operating modes in accordance with the calendar. In this case, all necessary time intervals and temperature values ​​are set for each day of the week, which leads to a reduction in electricity consumption by up to 70%.

To do this, periods are assigned when the heated floors must operate at full capacity or, conversely, be turned off for a certain time. All adjustment processes occur automatically, after all the necessary settings. For example, days from Monday to Friday and Saturday and Sunday are configured separately. The cycle will be repeated continuously until the settings are changed.

Thermostat for electric heated floors

Thermostats or thermostats are equipped with a temperature sensor, which allows you to maintain a set temperature by periodically turning the circuit on and off. The thermostat for infrared heated floors operating from the electrical network works in exactly the same way.

In most cases, heated floors are initially equipped with thermostats. If such devices are not included in the kit, they can be selected individually, since they are all standardized and suitable for all electrical systems warm floors.

Standard room devices have a power of 3-3.5 kW and are designed for a current of 16 amperes. If the power of the floors is higher than the power of the thermostat, the connection should only be made using a contactor. Each device is equipped with two temperature sensors - internal and external. The first measures the temperature of the floors, and the second measures the air temperature in the room.

In order to choose the best thermostat for a heated floor, you must be guided by certain criteria. First of all, the maximum power of the floor should be taken into account. Otherwise, the lack of power will cause the heating temperature of the cable to drop. If necessary, the devices are connected to a single network and freely provide a total power of over 3 kilowatts. They are installed separately at different ends of the room.

Another factor is the type of installation, that is, the regulators can be surface-mounted or built into the wall. Installation features of each device are reflected in the instruction manual. When choosing, you should also take into account the type of control. For example, devices that are simultaneously equipped with built-in and remote sensors are considered the most accurate. Great importance given functionality and ease of use.

How to install a thermostat for a heated floor

Before installing the device, be sure to read the attached operating instructions. It indicates the procedure for removing the front panel, that is, the control panel. This procedure must be carried out correctly, otherwise the device will become unusable. For built-in models, a recess is prepared into which the mounting box is inserted. It is recommended to place the thermostat close to outlets at a height of 0.6-1.0 m from the floor. Before starting work, the home network must be de-energized.

Installation of a heated floor thermostat begins with connecting the power wires to the installation box. Next, a temperature sensor is connected between the thermostat and the heating element, which is placed in a corrugated pipe.

The connection of wires to the thermostat must be carried out according to the established connection diagram. The phase and neutral wires are connected to the corresponding terminals, and the wires from the sensor are connected to separate sockets labeled sensor. The device itself fits neatly into the mounting box. If there is interference in the form of wires or corrugated tubes, they must be eliminated. The thermostat is located exactly level. After this, the control panel is installed in its place and secured with screws.

Setting the floor heating thermostat

Various models of thermostats can operate in manual and automatic mode. This factor must be taken into account when choosing a thermostat for a heated floor. All necessary adjustments depend on this. The hours and days of the week are set, and in-depth setup and calibration is also performed. If necessary, one of the temperature sensors can be disabled.

All adjustment steps are described in detail in the instruction manual. Separately, there is a lock against children, who may accidentally change the settings out of curiosity. To do this, press the “up” and “down” keys simultaneously. You need to unlock the thermostat using the same keys.

How to install a heated floor temperature sensor?

Design and purpose of a temperature sensor

So, the temperature sensor for a heated floor system is a thermistor protected by a glass bulb, and also has a copper conductor about 3 meters long for connection to the thermostat. In addition to the glass bulb for tile floors, the temperature sensor itself is also protected by a gel shell. The conductor is insulated with high-quality PVC (polyvinyl chloride) to protect it from external influences and damage. The length of the conductor can be increased, and naturally, reduced, up to 50 meters, the main thing is that there is an undamaged sensor at the end of the conductor.

To easily replace it in the future, it is recommended to place this structure in a metal-plastic tube, even if the manufacturer included a plastic corrugation with a diameter of 16 mm. The metal-plastic pipe has a smoother inner surface, so it is much easier to remove and install, as well as connect a new temperature sensor in case of failure. These types of temperature sensors are installed in hard floor coverings (under tiles or porcelain stoneware).

The principle of operation of the temperature sensor is very simple; when the temperature changes, its resistance changes, thereby giving a signal to the thermostat to turn on or off the heated floor system from 220 V, the most common network in everyday life.

Installation sequence

Let's move on directly to the installation of the heated floor and temperature sensor. First you need to determine the location of the thermostat, which will be located outside. It is most often located at a height of about 1 meter from the floor. Its mounting is similar to a regular socket.

Then you need to make grooves or grooves for laying two plastic pipes. One for the power wire leading to the heating element, the other for the electrical wiring of the sensor. The tube for the temperature sensor will be located on the floor. Such a gasket will make it possible to carry out repair work without removing the tiles, at least to replace control elements. It is not possible to completely replace the heating element if it is installed in a screed. It is important that when laying a pipe or cable corrugation there are as few bends and turns as possible. This will simplify the replacement of a failed temperature sensor in the future.

The next step is thermal insulation, it is carried out individually for different types of heating elements, for example, for a heating cable it is a damper tape or other insulation, the thickness of which is at least 1.5–2 cm. After this, the heating element is installed and secured with supply wires to the thermostat box.

Installing and connecting a heated floor temperature sensor has its own subtleties. In order to prevent solution from getting inside the tube where the sensor is located, its end on the floor is securely sealed with electrical tape or tape. It is not recommended to connect the entire system through an outlet; it is better to supply power from a circuit breaker and through a contactor (starter).

The temperature sensor should be installed at a distance of 0.5 to 1 meter from the wall on which the thermostat is installed, and also exactly in the middle between two adjacent turns of the heating cable. After installation, it is recommended to secure the temperature sensor with mounting tape or foil tape.

If a film heated floor is being laid, the temperature sensor must be installed under the heater sheet, as shown in the photo below. Please note that thermal insulation must be laid under the temperature sensor, otherwise the heating system will not be effective.

Important point! The location of the temperature sensor should be selected so that it is away from other heating sources. Otherwise, errors will occur and the warm floor will not work as it should.

The connection diagram for the heated floor temperature sensor is as follows:

Before making a screed, you need to check the functionality of the heated floor and the temperature sensor itself. As a rule, the resistance of both elements is measured. The system is considered operational if the resistance differs by no more than 10% from the passport data.

In order for the assembled circuit to be as safe as possible, it is recommended that in rooms where electric floor heating is carried out, protective shutdown devices are installed, which, in the event of a breakdown, will disconnect the circuit from the voltage, thereby protecting a person from falling under electrical potential. In damp areas this can be deadly.

Selecting a thermostat

I would also like to touch upon the thermostat itself, which plays a very important key role in this heating system. There are the following types of temperature controllers for heated floors:

• Electromechanical. The clarity of such adjustment is approximate, so achieving a specific set temperature is quite problematic. The main advantage of such a device is its low price.
• Electronic. The set value is set using touch buttons and has fairly clear settings and the ability to set the temperature limit down to one degree.
• Programmable electronic. By installing such an element, you can not only regulate the temperature in the room, but also turn on the heating according to a schedule, or only when there is a person in the room.

By the way, some thermostats already have a built-in sensor, which makes it possible to control not only the temperature of the floor, but also the air in the room as a whole.

As a result, I would like to remind you about the rules for working with electrical equipment; all connection work is carried out with the power turned off. At the same time, it is necessary to ensure that no one, except the person performing this work, accidentally supplies voltage dangerous to human health and life. This is where our technology for installing a heated floor temperature sensor with your own hands ends. We hope the information provided was useful to you!

Installing a heated floor temperature sensor

How to install a heated floor temperature sensor. Diagram for connecting the temperature sensor to the network. Installation errors, which are demonstrated in the video example.

Additional heating of the house, in many cases, is a necessary measure. And varying the intensity of heat supply becomes an urgent need. To do this, a heated floor temperature sensor is installed, which will allow maintaining an optimal microclimate in the home without active human participation in the control process.

Heated floor temperature sensor - purpose and types

Monitoring the condition of the underfloor heating system, electric or water, is required during its operation. And it's not just regulation temperature regime, but also supervision of the operating functions of the system.

The temperature sensor for heated floors, a remote version of the product, is manufactured based on the operating principle of a thermocouple. The main design element of the device is a bimetallic rod, the electrical resistance of which changes under the influence of ambient temperature. The control device is a thermostat, equipped with a built-in thermal converter of metal resistance values ​​into conventional thermal units.

Features of temperature sensors for heated floors

The temperature sensor for a heated floor is selected based on the following parameters:

• type of top covering;
• installation method;
• performing additional functions.

Under tiles, porcelain stoneware or boards, it is recommended to install a heated floor sensor with a reinforced protective housing so that massive materials do not deform the device. For lightweight flooring options, carpet or laminate, plastic covers are sufficient to protect the device.

Installation of the heated floor sensor can be done in the adhesive layer or in concrete screed. Additional functionality can be provided by signaling problems or monitoring limit temperatures.

Thus, the sensor for the heated floor thermostat performs several functions:

• saves energy by maintaining the set temperature within the specified limits;
• notifies about problems in the system;
• possesses self-sufficiency, carrying out a given program.

Selecting a thermostat for an additional heating system

Thermostats or system control units differ not only in brands and prices, but also in functionality and installation methods.

According to installation conditions, thermostats are produced:

• overhead mounted on a wall, for example – Caleo UTH-130;
• in a mounting box, for installation in a wall niche flush with the partition - Thermoreg TI 950 Design.

Based on functionality, floor temperature control units are divided into classic and programmable thermostats. IN classic version The device assumes the use of only a floor heating sensor. Programmable home heating control devices:

The range of capabilities of programmable floor heating control devices is quite wide and these are:

• stable operation of the device even with significant voltage drops;
• floor temperature adjustment from +1°C to +45°C;
• setting heating parameters for a day and a week;
• programming up to 5 different daily schedules in different days weeks;
• operation of the control unit in different modes during the day: “morning”, “night”, “at home”, “absence”;
• maintaining room and floor temperature within specified limits;
• saving specified parameters in cases of emergency power outage;
• self-learning function.

A significant role in choosing a thermostat is played by its power; it must correspond to the maximum power of the heated floor. It is not recommended to use sensors and thermostats from different manufacturers in the floor heating control system.

Installation of a temperature sensor for heated floors

For productive work control system, you need to know how to install a heated floor temperature sensor so that its readings are correct. First of all, the cable with the measuring device is placed in a strong but flexible tube with smooth inner walls. This will make it easier to remove it in case of replacement or repair. Additionally, to reduce possible injury to the sensor when removing it, the bending radius of the tube is taken to be at least 4-5 cm.

When installing heated tiled floors, a groove is cut into the concrete substrate to accommodate a tube with a sensor. It should be located between the turns of the heating cable or rods, and under no circumstances should it come into contact with the heating elements.

The temperature sensor is installed under lightweight materials by simply fixing it with construction tape. In the installation of film floors, the installation of a heated floor temperature sensor is carried out directly under the film, but with mandatory thermal insulation.

On the wall, where the tube with the temperature sensor approaches, a place for attaching the thermostat is installed. A starter or automatic circuit breaker (RCD - residual current device) is placed in front of the control unit, this is especially true for rooms with high humidity. The end of the tube, with the sensor placed in it, is tightly closed and effectively isolated from the penetration of liquid concrete or glue. The location of the sensor and thermostat should not be exposed to air flows that distort the real heating picture.

Connecting a heated floor temperature sensor

The instructions for the thermostat always indicate how to connect the heated floor sensor, usually these are the outer terminals on the left or right side control unit. After connecting the cables according to the diagram, the operation of the heating system is checked. The test can be carried out by measuring the resistance at the terminals of the sensor and heating elements or by turning on the system from the minimum temperature value to the value recommended by SNIP, that is, 30°C.

Only after making sure that the assembly is safe can you begin finishing work. It is worth remembering that the heating power of such systems can reach 6 kW. Therefore, a heated floor without a temperature sensor can become a dangerous device. This is especially true for thin coatings that are easy to heat and ignite, such as laminate or linoleum. In these cases, the question of whether it is possible to connect a heated floor without a temperature sensor should not even confront the consumer.

If malfunctions are detected in the heating floor temperature control system, it is not recommended to operate it until the heating device is fully operational.
