About Danfoss regulators
Why install a thermostat? To maintain a certain indoor air temperature.
The product consists of two parts that complement each other:
- Thermostat.
- Thermostatic valve.
The Danfoss thermostat valve is connected directly to the radiator, and a thermostat is already mounted on it.
The main thing is a thermostatic element that senses temperature changes and sends a signal to a valve that shuts off the flow of coolant.
Inside the thermal head is a bellows (a corrugated chamber that can change sizes) with gas. At a certain temperature, a gas changes its state (it condenses when cooled). This affects the change in volume and pressure in the chamber, which becomes smaller in size and pulls the spool rod, which in turn opens a gap in the valve for the circulation of the coolant.
When heating occurs, it starts reverse process expansion and the lumen is blocked (the standard is considered to be 2 V °C of temperature exceeding the specified value).
When the optimal degree is set on the instrument scale, a certain compression of the tuning spring appears inside, which is associated with a specific gas pressure.
Danfoss produces gas and liquid bellows (more inert, slower to react to temperature fluctuations).
Types and symbols
The abbreviations by which Danfoss heating thermostats are distinguished indicate the type of filler and the purpose of the device:
- RTS is a liquid bellows;
- RTD-G – gas-powered, suitable for one- and two-pipe systems without a pump;
- RTD-N is a gas device for one- and two-pipe pump systems.
Danfoss RTR/RTD thermostatic service element with built-in temperature sensor
There are modifications that perform not only their main functions, but also many additional ones. Let's say there is an option to protect against reconfiguration of set indicators. This is convenient when children are constantly in the room. The number of modes and variety of functions in each model is individual.
Popular models of Danfoss thermostats
IN product range The company has a variety of different Danfoss thermostats for batteries. The following are popular:
- RTD regulator marked 3640. It is used on 2-pipe classical type heating systems. Equipped with an option that prevents the line from freezing in cool weather. The Danfoss RTD thermostat is used in domestic and industrial environments and has four divisions with marks in the form of Roman numerals.
- The designation RAX, as a rule, is for products with liquid that are used for installation on unusual batteries or on heated towel rails. Externally they are very attractive and fit well into the design. The case has only divisions with Roman and Arabic numerals.
- The Danfoss RA-299 thermostat operates on gas, has automatic temperature control, and is produced in different colors. Reacts quickly to temperature fluctuations. Can only be used for installation on classic heating systems.
- The Living ECO device has the option of indoor climate control. It can be safely installed in various administrative buildings and residential buildings. The product is distinguished by the presence of an LCD screen, which displays all the necessary data about the thermal fluid. In addition, the case has main buttons for mode settings.
- There are also series with many functions; they are suitable for heated towel rails and for different areas of heating equipment. Can be right- or left-handed.
Danfoss Living Connect thermostat
All Danfoss thermostats for heating radiators are supplied with parts that simplify the installation of the device and its future use.
Installation of Danfoss thermal head
The device is mounted precisely on the pipe of the hot water supply circuit. Installation does not involve anything complicated, even in the case of designer options, installation follows the same principle. The work is carried out in stages:
- Markings are made on the supply pipe to indicate the area that needs to be cut. It is worth considering the dimensions of the valve body. The threaded element is removed, which will fit directly into the pipe.
- The heating is turned off and the liquid is drained to prevent a flood in the house.
- The excess section of the pipe is cut off according to the marks, and a thread is made with a die on the outer part of the cut.
- The joint is treated with a special paste for plumbing work(manufacturer is not important).
- The valve is screwed onto the thread made with a die and tightened tightly with a washer. There is no need to further secure the connection for tightness. The actions performed are sufficient for a reliable connection.
- The fuse is removed, the maximum value of “five” is set on the regulator, and a housing with a scale is put on top.
- All joints are checked and the heating device is connected to the entire heating system.
If the Danfoss thermostat was connected correctly, then there should be no problems. It is worth checking the operation of the device before opening and closing the valve for the first time.
Setting up the thermostat
All the manufacturer’s devices differ in appearance and technical characteristics, but they are still configured in the same way. To implement it, you need to look at the operating instructions and familiarize yourself with the designation of the modes that are indicated on the device body. Indicators may vary, depending on the model.
Next, to adjust the Danfoss thermostat, set it to the required temperature. This can be done by moving the torque element in a certain direction. If you have installed a device with buttons, all you need to do is press the plus or minus.
It is possible to specify intermediate values when they the best way suitable for creating a specific temperature regime in room. A couple of minutes will pass, and the heating system will have time to adapt to the specified parameters and will heat until the optimal microclimate is achieved. The same applies to refrigeration equipment.
Operation of the regulator in a heated floor system
The Danfoss heated floor thermostat is an important thing for the entire heating system. The device has the responsible function of adjusting the temperature to a comfortable 25 °C.
Flow meters will not help if the pressure is unstable, the air is heated, for example, by the sun's rays, and residents are trying to save on heating while they are not at home.
Experts advise installing a mechanical regulator in small rooms of approximately 10 m².
In large rooms, Danfoss room thermostats with heated floor temperature sensors are used.
The Danfoss thermostatic head deservedly has many positive reviews. This is an easy-to-use item that does not require special attention from the owner after installation and adjustment. As a result, a favorable microclimate is provided in the house, and in some cases, significant savings in money.

Technical characteristics of thermostatic elements of the RA 2000 series
The main device of the thermostatic element is a bellows, which provides proportional control. The thermocouple sensor senses changes in ambient temperature. The bellows and sensor are filled with an easily evaporating liquid and its vapor. The adjusted pressure in the bellows corresponds to its charging temperature. This pressure is balanced by the compression force of the tuning spring. As the air temperature around the sensor increases, some of the liquid evaporates and the vapor pressure in the bellows increases. At the same time, the bellows increases in volume, moving the valve spool towards closing the hole for the flow of coolant into the heating device until an equilibrium is achieved between the spring force and the vapor pressure. When the air temperature drops, the vapors condense and the pressure in the bellows drops, which leads to a decrease in its volume and movement of the valve spool towards the opening to a position at which equilibrium of the system is again established. The vapor fill will always condense in the coldest part of the sensor, usually furthest from the valve body. Therefore, the radiator thermostat will always respond to changes in room temperature without sensing the temperature of the coolant in the supply pipe. However, when the air around the valve does become heated by the heat given off by the piping, the sensor may register a higher temperature than the room temperature. Therefore, to eliminate such influence, it is recommended to install thermostatic elements, usually in a horizontal position. Otherwise, it is necessary to use thermocouples with a remote sensor.
Selecting the thermostatic element type
Thermostatic elements with built-in sensor
When choosing a thermostatic element, you should be guided by the rule: the sensor must always respond to the air temperature in the room.
Thermostatic elements with integrated sensor must always be positioned horizontally so that ambient air can circulate freely around the sensor. They should not be installed in a vertical position, since the thermal effect on the sensor from the valve body and heating system pipe will lead to improper functioning of the thermostat.
Thermostatic elements with remote sensor
Thermostatic elements with a remote sensor should be used if: o the thermoelements are covered with a blind curtain; o the heat flow from the heating system pipelines affects the built-in temperature sensor; o the thermoelement is located in the draft zone; o Vertical installation of the thermoelement is required. The remote sensor of the thermostatic element must be installed on a wall free from furniture and curtains or on a baseboard under a heating device if there are no heating system pipelines there. When installing the sensor, the capillary tube should be pulled out to the required length (maximum 2 m) and secured to the wall using the supplied brackets or a special gun.
RAW series thermostatic elements
Thermostatic elements of the RAW series are automatic temperature control devices designed to complete radiator thermostats of the RA type. The radiator thermostat is a direct-acting proportional air temperature controller with a small proportional band, which is currently equipped in heating systems of buildings for various purposes. The thermostat type RA consists of two parts: a universal thermostatic element of the RAW series and a control valve with pre-set capacity RA-N (for two-pipe heating systems) or RA-G (for a single-pipe system).
The production program for thermostatic elements of the RAW series includes:
Thermostatic elements of the RAW series are equipped with devices for protecting the system from freezing, fixing and limiting the temperature setting. The RAW 5012 is equipped with an ultra-thin 2 m long capillary tube, which is wound inside the sensor housing and connects the remote sensor to the thermostatic element. During installation, the pipe is pulled to the required length. The clip connection allows for simple and precise attachment of the thermocouple to the valve.
Technical characteristics of radiator thermostats with RAW series thermoelements comply with European standards EN 215-1 and Russian GOST 30815-2002.
To prevent unauthorized dismantling, the thermoelement can be fixed to the valve using a special lock (see Accessories).
Technical characteristics of RAW series thermostatic elements
The main device of the thermostatic element is a bellows, which provides proportional control. The thermocouple sensor senses changes in ambient temperature. The bellows and sensor are filled with a special heat-sensitive liquid. The adjusted pressure in the bellows corresponds to its charging temperature. This pressure is balanced by the compression force of the tuning spring. As the air temperature around the sensor increases, the liquid expands and the pressure in the bellows increases. At the same time, the bellows increases in volume, moving the valve spool towards closing the hole for the flow of coolant into the heating device until an equilibrium is achieved between the spring force and the liquid pressure. As the air temperature drops, the liquid begins to compress and the pressure in the bellows drops, which leads to a decrease in its volume and movement of the valve spool towards the opening to a position at which equilibrium of the system is again established. To eliminate the influence warm air It is recommended to install thermostatic elements from the heating pipe of the heating device, usually in a horizontal position. Otherwise, it is necessary to use thermocouples with a remote sensor.
Thermostatic elements of the RAW-K series
Thermostatic elements of the RAW-K series are automatic temperature controllers with a small proportional band. RAW-K are designed for installation on thermostat valves from Heimeier, Oventrop or MNG, built into a steel structure panel radiators type Biasi, Delta, DiaNorm, Diatherm, Ferroli, Henrad, Kaimann, Kermi, Korado, Purmo, Radson, Superia, Stelrad, Veha, Zehnder-Completto Fix. The thermostatic element of the RAW-K series has a liquid sensor with a temperature setting range of 8-28 ° C and is equipped with a device for protecting the heating system from freezing.
The Danfoss company produces 3 modifications of RAW-K series thermoelements:
The RAW-K 5032 is equipped with an ultra-thin 2 m long capillary tube, which is wound inside the remote sensor housing, connecting it to the working bellows of the thermostatic element. During installation, the tube is pulled to the required length. Thermostatic elements of the RAW-K series comply with European standards EN 215-1 and Russian GOST 30815-2002.
Electronic radiator thermostat Living eco
Electronic radiator thermostat Living eco® is a programmable microprocessor controller for maintaining a given air temperature, mainly in residential buildings served by a water heating system. The thermostat is designed for installation on the valves of radiator thermostats instead of traditional thermostatic elements.

The P0 program maintains a constant air temperature throughout the day. Programs P1 and P2, in order to save energy, can reduce the temperature in the room at certain periods of time, which allows you to adapt the operation of the heating system to the lifestyle of the people living in it.
The Living eco® thermostat is supplied complete with adapters for installation on the valves of Danfoss thermostats, as well as most other manufacturers. Installing and configuring the Living eco® thermostat is easy; there are only three buttons on the panel.
The Living eco® thermostat is equipped with an open window function, which turns off the coolant supply to the heating device when the room temperature drops sharply, which reduces heat loss and thereby increases the efficiency of the heating system.
Main characteristics of the thermostat:
Pre-installed programs
The "long absence" function allows you to reduce the temperature in the room when it is not in use. The period of absence and temperature are customizable by the consumer.
The selection of programs and their settings are made in accordance with the instructions supplied with the thermoelement.
TWA series thermoelectric actuators
Thermoelectric mini-actuators of the TWA series are designed for on-off control of various control valves in heating and heating and cooling systems of local ventilation units.
The actuator is equipped with a visual travel indicator that shows whether the valve is in closed or open position.
TWA actuators, depending on the modification, can be used with valves of the RA, RAV8 and VMT series manufactured by Danfoss, as well as with valves from Heimeier, MNG and Oventrop, which have a thread for mounting the actuator M 30 x 1.5. If the actuator is used with other types of valves, the valve must be checked to ensure compatible geometry and proper closure. The supply voltage of the electric drive is 24 or 230 V. The valves can be normally closed in the absence of voltage (NC) and normally open (NO). In addition, the normally closed actuator with 24 V supply voltage is supplied with a limit switch (NC/S).
Thermostat valves with pre-setting RA-N and RA-NCX DN = 15 mm (chrome plated)
Control valves RA-N and RA-NCX are intended for use in two-pipe pump water heating systems.
RA-N is equipped with a built-in device for pre-setting (installation) its throughput within the following ranges:
Valves RA-N and RA-NCX can be combined with all thermostatic elements of the RA, RAW and RAX series, as well as with the TWA-A thermoelectric actuator.
To identify the RA-N and RA-NCX valves, their protective caps are painted red. The protective cap must not be used to block the flow of coolant through the heating appliance. Therefore, the handle (code no. 013G3300) must be used.
Valve bodies are made of pure brass, nickel plated (RA-N) or chrome plated (RA-NCX).
The technical characteristics of the RA-N and RA-NCX valves in combination with thermostatic elements of the RA, RAW and RAX series comply with the European standards EN 215-1 and the Russian GOST 30815-2002, and the connecting thread size complies with the HD 1215 standard (BS 6284 1984). All radiator thermostats manufactured by Danfoss are manufactured in factories certified to ISO 9000 (BS 5750).
To prevent deposits and corrosion, the valves of the RA-N and RA-NCX thermostats should be used in water heating systems where the coolant meets the requirements of the Rules for the technical operation of power plants and networks Russian Federation. In other cases, you must contact Danfoss. It is not recommended to use compositions containing petroleum products (mineral oils) to lubricate valve parts.
Adjustment to the calculated value is carried out easily and accurately without the use of special tools. To do this, perform the following operations:
Pre-setting can be made in the range from "1" to "7" at intervals of 0.5. In position "N" the valve is fully open. Installation on the dark area of the scale should be avoided.
When the thermostatic element is installed, the pre-setting is hidden and thus protected from unauthorized changes.
Thermostat valve with presetting RA-N with press fitting
The RA-N valve is intended for use in two-pipe water heating pump systems with copper or of stainless steel. Special crimping tools are required to connect the valve connection to the pipeline. Valve body appearance and technical characteristics are identical to standard valves RA-N DN = 15 mm. RA-N can be used with all types of thermostatic elements from the RA or RAW series, as well as with specially designed thermostatic elements such as RAX and TWA-A thermoelectric actuator.
The RA-N control valve is equipped with a built-in device for pre-setting (installation) its flow capacity Kv in the range from 0.04 to 0.73 m3/h.
To identify the valves, the protective cap is painted red. The cap should not be used to block the regulated medium. For these purposes, a special metal handle (code number 013G3300) should be used. The valve body is made of nickel-plated DZR brass and the pressure pin is made of stainless steel. The pin does not require lubrication during the entire life of the valve. The gland seal can be replaced without draining the piping system. RA-N should be used in water heating systems where the coolant meets the requirements of the Rules for the technical operation of power plants and networks of the Russian Federation. In other cases, you must contact Danfoss. It is not recommended to use compositions containing petroleum products (mineral oils) to lubricate valve parts.
High capacity thermostat valve RA-G
The thermostatic valve with increased flow rate RA-G is intended for use, as a rule, in single-pipe water heating systems with pump circulation of coolant that meets the requirements of the Rules for the technical operation of power plants and heating networks of the Russian Federation. The valve is not recommended to be used if the coolant contains mineral oil impurities.
The RA-G is equipped with a seal that can be replaced without draining the heating system. The pressure pin in the stuffing box is made of chrome-plated steel and does not require lubrication throughout the life of the valve. All versions of RA-G valves can be combined with any thermostatic elements of the RA series.
RA-G valves are supplied with gray (to identify them) protective caps, which should not be used to block the flow of coolant. Therefore, a special metal service locking handle (code no. 013G3300) must be used.
Set of thermostatic fittings X-traTM for heated towel rails and design radiators.
The X-tra™ thermostatic kit is specially designed for heated towel rails. It consists of a thermostat valve, a thermostatic element and a shut-off valve with drainage function. The innovative self-sealing connection of the valves to the radiator is made using one-half inch threads. The valves and thermoelement are available in white, chrome and steel versions and are suitable for most heated towel rails. This set is the perfect complement to a heated towel rail. Attractive and compact design allows you to install the thermostat under the heated towel rail parallel to the wall, eliminating accidental impacts on it.
The range includes two types of thermostats with different control principles:
- RAX, which regulates the room temperature;
- RTX, which detects and regulates the temperature of the water leaving the heated towel rail. Used on heated towel rails and adjustable 5-10°C above room temperature, the RTX thermostat provides a constant temperature for drying towels.
The valve assembly is a body with a double-sided self-sealing fitting, which has two sealing rings: one to seal the connection between the fitting and the heated towel rail, and the second to seal the connection between the fitting and the valve body. The Allen screw serves to provide a seal between the valve body and the fitting. If the O-rings do not fit into the fittings of the heated towel rail, a traditional sealing material is used.
Danfoss thermostat is a device that is widely used in various home and industrial heating systems. Such samples are distinguished by high quality, accuracy and ease of use.
Let's study their features in more detail so that you can also use these advanced mechanisms for your systems.
Description and purpose
Danfoss regulator is a device that is used to regulate the air temperature in a room. Such a device can be used in various heating systems, including those where the heat carrier is water.
The regulator allows you to manually control the operation of such a system, use heat economically, and also turn the entire heating system on and off. The thermostat is used both in home networks and in closed ecosystems such as greenhouses, or in industries. It is also used to operate refrigerators, air conditioners and other systems in which it is important to maintain temperature conditions.
1.1 Design of Danfoss thermostats
Danfoss regulator, regardless of its design. It is a small chamber filled with gas or liquid. This liquid or gas expands when exposed to temperature, pressing on the shut-off valve, which stops the flow of heating fluid into the radiator, causing the system to increase the temperature.
When the room cools, the liquid contracts and a reverse reaction occurs. This operating system is valid for all types of radiators, including products for refrigerators. Almost all products from this manufacturer work according to this principle, including Danfoss RTD and the Danfoss RA line, as well as many others.
2 Model range of Danfoss thermostats
Danfoss has a fairly wide range of thermostats. Currently, its products include the following types of devices:
- thermostats for controller design model range 013G4001- 013G4009. Applicable for heated towel rails, as well as various sections of heating networks. Available in versions for right- and left-hand installation;
- Danfoss RTD 3640 is a type of model for heating systems. Designed for a two-pipe standard system. They have an RTD function to protect against freezing for the winter. This variety is suitable for home and industrial heating systems, but not for refrigerators. It has only 4 divisions, indicated by both Arabic and Roman numerals;
- RAX models with liquid filler. This series is also intended for heated towel rails and design radiators. The model is applicable to most modern versions of design radiators; it has divisions with both Arabic and Roman numerals;
All presented versions of thermostats are accompanied by a whole series of special accessories that simplify their installation, as well as further use.
Almost all thermostats released in this series are available in three various options: golden, white, silver. You can choose the type that suits your system, the valve and temperature jack work in almost the same way.
2.1 How to install a Danfoss thermostat?
The Danfoss regulator is mounted directly on the hot supply pipe of your heating system. Installation of any model, including the RTD 3640, RA, is easy. To work in in this case you will have to do this:
- We disconnect the system from the general power, cut off the pipe the right size for installing a thermostat. Without this step, the installation will not proceed.
- Using special tools, we make a thread on the existing pipe onto which the thermostat will be installed.
- We treat the area with plumbing paste, and then attach the RTD 3640, RA or any other valve body to it.
- We connect the device itself to the valve, tightening the connection with a washer. Additional sealing is not needed here.
- We remove the fuse, set the thermostat to the maximum value of 5, then put a cap with a scale on it. It is important to install it until it clicks for the tightest and highest quality fit.
- We check the sealing of the system again, after which we can connect it back to common system supplies. Let the valve open and close once and you will be sure that the equipment is working correctly.
Installation of RTD, RA or other model is complete. Now you can use the device freely.
2.2 How to set up a Danfoss thermostat?
Setting up a device such as the Danfoss RTD regulator, RA is quite simple and accessible to all users. In order to do this, you need to study the temperature scale available at the end of the device (it may differ slightly depending on which version you are using). Then set the temperature you are interested in by simply moving the pointer on the device to the parameter you need.
You can also choose intermediate values if they suit you. Within a few minutes the valve will adjust to the desired position, and the temperature in the apartment will reach the required parameter, and you will be able to enjoy the most comfortable microclimate for you. The valve is adjusted in the same way for models for refrigerators.
2.3 Danfoss thermostat and its types (video)
In many countries, up to 40% of energy resources are spent on the needs of ventilation and heating of buildings. This is several times more compared to advanced European countries.
Need for use
The issue of energy saving is especially acute; this is relevant against the backdrop of a constant increase in energy prices. One of the devices that allows you to save thermal energy, is a thermostat for radiators; its installation reduces heat consumption by 20%. To do this, the consumer needs to choose the right design for the heating system, as well as carry out installation, you can find out about this by reading below.
Principle of operation
The Danfoss thermostat is designed to maintain a constant indoor temperature. Such devices were first used back in 1943. The mentioned company is a market leader in the production and sale of such units. Structurally, the devices consist of 2 main elements, namely a thermal head and a valve, which are connected by a locking mechanism. The purpose of the thermal head is to determine the temperature environment In order to regulate the impact on the actuator, the latter acts as a valve. It is designed to cover the flow of water that enters the radiator. This method of regulation is called quantitative, since the device can affect the flow of water that passes into the battery. There is another method, called qualitative, with its help the temperature of the water changes in the system. This is done through namely This element must be located in or the boiler room. The Danfoss thermostat has a bellows inside, which is filled with a heat-sensitive medium. It can be gas or liquid. The latter type of bellows is easier to manufacture, but does not operate as quickly as its gas counterparts, which is why the latter have become so widespread. When the air temperature level increases, the substance that is in a confined space acquires a more impressive volume; the bellows, stretching, affects the valve stem. The latter is moved downwards by a cone, which is designed to reduce the flow area. This allows you to effectively reduce water consumption. When the air temperature drops, this process occurs in the reverse order, and the volume of coolant increases to the optimal limit, which is how the Danfoss thermostat works.
Consumer Reviews
Depending on what type of heating system is used, as well as what the installation technology is, thermal heads and valves can be used in different combinations to control the flow of water. If we are talking about single pipe system, then you should use a valve that is characterized by increased throughput and insignificant As users say, the same recommendation can be used in the case of a two-pipe gravity system, where water circulates naturally and is not affected by forced stimulation. If you decide to choose a Danfoss thermostat, you can install it on two-pipe system, which is equipped with a circulation pump. Moreover, according to reviews, the valve should be able to adjust the capacity. It is done quite simply, and there is no need to use a special tool for this. Once you have decided which valve to use, you should decide on the type of thermal head.
If you are interested in a Danfoss thermostat, the installation instructions for which will be presented below, you can purchase it at an affordable price. When determining the type of thermal head, you should know that it is offered for sale in some varieties. Thus, there may be a thermocouple inside. Among other things, it can be portable. Sometimes the regulator is external. Devices can also be programmable, in which case they are electronic. You can also choose a vandal-proof thermal head. According to users who have chosen a regulator with an internal sensor, this device should only be installed if it is possible to position it horizontally. Then the air in the room will flow freely to the body of the device.
For reference
After you have purchased a Danfoss radiator thermostat, you should familiarize yourself in more detail with the features of its installation. Thus, it is completely unacceptable to install it on a radiator in a vertical position. In this case, the heat flow will constantly rise upward, and increased temperatures from the supply pipeline and housing will affect the bellows. Ultimately, you will encounter the device not working correctly.
Customer reviews on choosing a thermostat
Home craftsmen especially emphasize that in some cases it is not possible to install the device horizontally. Then it is recommended to buy a remote one that comes complete with a capillary tube. The length of the device is 2 meters. It is recommended to place the device at this distance from the battery by installing it on the wall. Buyers emphasize that the inability to install the regulator horizontally does not always indicate the need to purchase a remote sensor. There may be others to this objective reasons. The Danfoss thermostat, the operating principle of which was described above, cannot be installed behind thick curtains; in this case, of course, the best solution would be to purchase a remote sensor. Among other things, such a need arises when there is a heat source near the thermal head or hot water supply pipes pass. You can resort to this solution even when the radiator is located under a sufficiently wide window sill. In this case, the thermoelement may fall into the draft zone. Buyers claim that if at least one of the above conditions is met, then it is best to purchase a remote sensor.
Installation instructions
The Danfoss thermostat, reviews of which are presented in the article, must be installed using a certain technology. The first recommendation is to avoid installing the thermal head on the heater within sight. Batteries whose total power is equal to 50 percent or more of all that are in the same room should be regulated. Thus, when there are two in a room heating devices, the thermostat should be on one battery, whose power is more impressive. If you are interested in Danfoss - a thermostat, the setup of which is quite simple, you can purchase and install it. The first part of the device, which acts as a valve, should be installed on the supply pipeline. If it needs to be inserted into an already assembled system, the supply line must be dismantled. This work may involve some difficulties if the connection is made using steel pipes. The master will have to stock up on tools for cutting the material.
Conclusion
Danfoss is a fairly popular company on the market for relevant products today. The thermostat (how to regulate it is indicated in the instructions) must be installed on the radiator. The thermal head is then mounted without using additional tool. This is very easy to do at home, in addition, you will be able to save on purchasing consumables.
