Check the price and buy heating equipment And you can have accompanying goods. Write, call and come to one of the shops in your city. Delivery throughout the Russian Federation and CIS countries.

The production technology based on a gas-filled bellows has a patent and is used on its own company plants. If you are leying for the purchase of the Danfoss thermostat, then be sure to read the instruction manual.

About Danfoss regulators

Why are the thermostat set? To maintain a certain air temperature in the premises.

It consists of a product of two parts that complement each other:

  1. Thermostat.
  2. Thermoregulation valve.

The Danfoss thermostat valve is connected directly to the radiator, and the thermostat is already mounted on it.

The main thing is a thermostatic element that catches the temperature changes and gives a signal to the valve overlapping the heat carrier stream.

Inside the thermal heads - the bellows (corrugated chamber that can change dimensions) with gas. The gas at a certain temperature changes its state (when cooled condenses). This affects the change in the volume and pressure in the chamber, which becomes smaller in size and pulls the range of the spool, which turns out in turn in the lumen valve for circulating the heat carrier.

When heating occurs, the reverse expansion process starts and the lumen is overlapped (the standard is considered to be 2 in ° C of the temperature indicator above the specified).

When putting an optimal degree on the scale of the device, a certain compression of the setting spring appears inside, which is associated with a specific gas pressure.

Danfoss produces gas bellows and liquid (more inert, slower react to temperature fluctuations).

Types and symbols

Abbreviations, according to which the heating thermostators Danfoss differ, mean the type of filler and the appointment of the device:

  • RTS is a liquid bellows;
  • RTD-G - gas operating, suitable for single and two-pipe system without pump;
  • RTD-N is a gas device for single and two-pipe pump system.

  5. There are also a series with a multitude of functions, they are also suitable for heated towel rails, and for different sections of equipment under heating. There may be right and left-sided type.

Danfoss Living Connect thermostat

All Danfoss thermostators for heating radiators have parts that simplify the device fastening and its future use.

Installation of the thermal head Danfoss.

The device is mounted on the hot water circuit pipe. Installation does not imply anything complicated, even in the case of designer optionsMounting occurs according to one principle. The work is carried out in stages:

  1. Placement on the feed pipe to designate the area, which will be required to cut. It is worth considering the size of the valve body. The threaded element takes place, which will come directly into the pipe.
  2. The heating is turned off and the liquid descends, to eliminate the flood in the house.
  3. At the marks, the extra section of the pipe is cut, and the cutting is made on the outer part of the cut.
  4. The joke is processed special paste For plumbing works (the manufacturer is not important).
  5. The valve is screwed on the thread made and is tightened with a washer. Additionally, the connection for tightness is not required. Action performed enough for a reliable junction.
  6. The fuse is removed, the maximum "five" parameter is installed on the regulator and the body with a scale is put on top.
  7. All joints are checked and a thermal device connects to the entire heating system.

If the DANFOSS thermostat is connected correctly, there should be no problems. It is worth checking the operation of the device to the first opening and closing of the valve.

Setting the thermostat

All manufacturer's devices differ in externally and technicians, but still their setup is made equally. To implement it, it is necessary to look into the instructions for use and familiarize yourself with the designation of the modes, which are indicated on the instrument housing. Indicators may differ, it all depends on the model.

Next, to adjust the Danfoss thermostator, put the required temperature on it. This can be done using the movement of the torque element in a specific side. If you installed the device with the buttons, everything you need is to click on the "plus" or "minus".

It is possible to specify intermediate values \u200b\u200bwhen they the best way are suitable for creating a certain temperature mode in room. Will pass a couple of minutes, and the heating system will have time to adapt to the specified parameters and will warm until it turns out optimal microclimate. Also tuning and for refrigeration equipment.

Operation of the regulator in a warm floor system

Danfoss warm floor thermostat is an important thing for the entire heating system. The device lies a responsible function to adjust the temperature to a comfortable 25 ° C.

Flow meters will not help if the pressure is unstable, the air heats up, let's say sunny raysAnd the tenants seek to save on heating while they are not at home.

Mechanical regulator Specialists advise to put in small rooms by about 10 m².

In large rooms apply indoor thermostators Danfoss with heat heating temperature sensors.

Thermostatic head Danfoss deservedly has a lot positive feedback. This is an easy-to-use element that does not require special attention from the owner after installation and adjustment. As a result, a favorable microclimate is ensured in the house, and in some cases, and tangible cash savings.

In many countries, up to 40% of energy resources goes to the needs of ventilation and heating of buildings. It is several times more compared to advanced European states.

The need for use

The issue of energy saving is especially acute, it is relevant against the background of a constant increase in energy prices. One of the devices that saves thermal energy- This is a thermostat for radiators, its installation reduces heat consumption by 20%. To do this, the consumer needs to be correctly selected to the design to the heating system, as well as make installation, you can find out if you read below.

Principle of operation

The Danfoss thermostat is designed to support the constant temperature indoor. For the first time such devices began to be used in 1943. The company mentioned is the market leader in the production and sale of such aggregates. Constructively, the devices are in composition 2 of the main element, namely the thermal head and the valve, which are connected by the locking mechanism. The purpose of the thermal head is to determine the ambient temperature to adjust the impact on the actuator, the valve protrudes as the latter. It is designed to cover the flow of water that enters the radiator. Such a regulation method is called quantitative, as the device can affect water consumption that goes into the battery. There is another method called high-quality, with its help the water temperature changes in the system. This is done by name, namely, this element must be in or boiler. The Danfoss thermostat has inside the bellows, which is filled with a heat sensitive medium. It can be gas or liquid. The last variety of bellows is easier in manufacture, but does not show such speed as gas analogues, so the latter have gained so widespread. At the time of increasing the level of air temperature, the substance that is in a closed space acquires a more impressive volume, the bellows, stretching, has an impact on the valve stem. The latter move down the cone, which is designed to reduce the passage section. This allows you to effectively reduce water consumption. With low air temperature this process proceeds in reverse orderAnd the volume of the coolant increases to the optimal limit, and the Danfoss thermostat works.

Consumer reviews

Depending on which type of heating system is used, as well as the installation technology, thermal heads and valves can be used to control water flow. of different combinations. If a we are talking About the single-pipe system, the valve should be applied, which is characterized by increased bandwidth and insignificant, according to users, the same recommendation can be used in the case of a two-pipe samotane system where the water circulates naturally and does not affect the forced motivation. If you decide to choose the Danfoss thermostat, then you can install it on a two-pipe system, which is equipped with a circulation pump. In this case, according to the reviews, the valve must have the ability to adjust the bandwidth. It is fairly simple, and it is not necessary to apply a special tool for this. After you decide what valve to use, it is necessary to determine the type of thermal head.

If you are interested in Danfoss - the thermostat, the installation instructions for which will be presented below, - you can purchase it at an affordable cost. Determining the type of thermal heads, you should know that it is proposed for sale in some varieties. Thus, inside may be a thermoelement. Among other things can be remote. Sometimes the regulator is external. The devices are also programmable, in this case they are electronic. You can choose and anti-vandal thermal head. According to users who chose a regulator with an internal sensor, this device should be installed only if it is possible to arrange it horizontally. Then the air in the room will freely go to the instrument housing.

For reference

After you were purchased radiator thermostat Danfoss, it is worth familiar with the features of its installation. Thus, it is completely unacceptable to install it on the radiator in a vertical position. In this case, the heat flux will constantly rise upwards, and elevated temperatures from the feed pipeline and the housing will influence the bellows. In the end, you will come across that the device will work incorrectly.

Customer Reviews on the choice of thermostat

Homemade masters especially emphasize that in some cases there is no possibility to install the device horizontally. Then it is recommended to buy a remote one that comes with a capillary tube. The length of the device is 2 meters. At such a distance from the battery, it is recommended to have a device by installing it on the wall. Buyers emphasize that not always the absence of the installation of the regulator horizontally indicates the need to purchase a remote sensor. This may be other objective reasons. Danfoss thermostat, the principle of which was described above, cannot be installed in any way behind the dense curtains, in this case, of course, better decision It will be the purchase of a remote sensor. Among other things, such a need arises in the case when there is any source of heat next to the thermal head or the hot water pipes pass. You can resort to such a solution, and when the radiator is under a sufficiently wide window sill. In this case, the thermoelement can fall into the area of \u200b\u200bthe draft. Buyers claim that if at least one of the above conditions is observed, it is best to get a remote sensor.

Installation Instructions

The Danfoss Temperature Regulator, the reviews about which are presented in the article should be installed according to a specific technology. As the first recommendation, it is an elimination of the installation of the thermal heads on the heater within visibility. Regulation should be subject to battery whose general power equal to 50 percent and more from all that are in the same room. Thus, when there are two heating instruments in the room, the thermostat should be on the same battery, whose power is more impressive. If you are interested in Danfoss - a thermostat, the setting of which is simply made enough, it can be purchased and installed. The first part of the device whose role is the valve, should be installed on the feed pipeline. If it is necessary to embed it to the already assembled system, the feed liner must be dismantled. These works may assume some difficulties if the connection is made using steel pipes. The master will have to stock material tool.

Conclusion

A fairly popular company today in the market of relevant goods is Danfoss. The thermostat (how to adjust it is indicated in the instructions) must be installed on the radiator. The thermal head after that is mounted without using additional tool. It is very easy to do at home, in addition, it will be possible to save on the purchase of consumables.

Danfoss Temperature Management - Operating Instructions

Installation on the thermostat radiator is the ability to reduce the cost of heating, improving the microclimate in the house, as well as the maintenance of Earth energy resources.

The motives can be different, but the decision is incarnated in life more and more.

Many, choosing equipment manufacturer, stop at Danfoss.

And not surprisingly products famous brand Easy to meet on the shelves of many stores.

The production technology of their thermostats based on a gas-filled bellows is patented and applied at its own company plants. If you also decided to purchase a Danfoss thermostat, the installation and operation instruction will be by the way.

The goal of the installation of the thermostat is maintaining the selected by the consumer, the air temperature in the house.

The design of the thermostator for radiators includes two elements, complementary by each other:

  1. Thermostat (or thermostatic element).
  2. Danfoss thermostat valve.

The valve is connected directly to the battery, and the thermostatic element is installed on it.

Basis base is a thermostat. It is he who reacts to a change in the ambient temperature and affects the valve that overlaps the coolant stream.


Temperature regulator Danfoss.

Inside the thermostat head - a bellows (corrugated chamber capable of changing the size), filled with gas. Gas, depending on the temperature, changes its aggregate state (chilled it condensed). This leads to a change in volume and pressure in the chamber. The camera decreases in size, pulls the stem of the spool, which opens a greater clearance in the valve for the receipt of the coolant.

When heated, the reverse process of expanding and overlaping the lumen occurs (adopted standard - 2 V ° C of excess air temperature over specified).

When a comfortable temperature is displayed on the regulator scale, a certain compression of a tuning spring is established inside, which is interconnected with a certain gas pressure.

Danfoss produces gas bellows inside, as well as liquid. The latter are more inert, react to a change in temperature slower.

Types and symbols:

  • RTS - liquid bellows;
  • RTD-G is a gas beam for a single-tube system, or two-pipeless without pump;
  • RTD-N is a gas beam for a two-pipe system, and systems with a circulation pump.

Danfoss Radiator Regulators RA 2991

There are also modifications of thermoelements in which:

  • Protection from reconfiguration with random persons (a great option for public institutions and children's rooms).
  • there is remote thermal catcherconnected by a two-meter capillary tube, which can be installed away from the radiator, blown in a niche or forced furniture, which gives a more accurate measurement result.
  • With a range of temperatures, slightly less than ordinary sensorsFor integration into the system where payments are made on standards.

Heating system of floors

Thermostators are used for the heating system of floors. The thermostat for warm floors is simply necessary!

After all, driving fluid into the floor circuit, you need to lower its temperature from 60 to 90 in ° C, to a comfortable 35 - 40 V ° C (while the surface of the floor itself will be about 25 in ° C).

Flow meters are powerless if the pressure is jumping in the system if the air heats up, for example, from the Sun, and even if the tenants want to save on heating during their absence.

Thermomechanical regulator is better to apply for small rooms, about 10 m2.

For large areas, indoor temperature regulators use with a warm floor temperature sensors.

First of all, the valve on the radiator is mounted. For this, the flow of the coolant is overlap.

  1. There is a markup on the feed pipe. The site that will need to cut out should be in length correspond to the size of the valve body minus threaded connections.
  2. The heating pipe is cut, superfluous cuts.
  3. Using the layer, or dice, on outside Cutting pipe is made thread.
  4. The compound is processed by plumbing paste and fum-ribbon.
  5. The body of the valve hills the resulting thread.
  6. Since it is impossible to twist the pipe, from the opposite side of the valve, a cape-nut-American woman twists, and then screwed (hexagoned key) into a slice of the radiator.
  7. The body of the device is screwed into its own naked nut through the rubber washer. This connection is not necessary to somehow seal, the main thing is that it is clean.
  8. After the valve is installed on the radiator, the protective cap is removed from it (located perpendicular to the pipe).

The thermal head is set to the maximum temperature value, after which it dresses on the valve with pressing (before clicking).

Installation of the sensor

As already mentioned, the remote sensor is needed if the battery is built into the wall or something closed (furniture, screen, dense curtains).

In one case of this item, a sensor and a tuning node are combined.

  1. It is best to place the device on the open (but without drafts) of the wall, at an altitude of about 1.4 m. From the floor. Avoid places near instruments that can change the temperature of the medium - air conditioners. kitchen plates etc.
  2. Included in the device there is a small mounting panelwhich is fixed to the selected place with a pair of self-tales.
  3. Inside the sensor, the capillary tube is mixed. It is pulled into the desired length so that the device reaches the fixed plank.
  4. The capillary tube is neatly fixed on back side valve.
  5. The sensor is placed on the bar by simply snatching.

Installation of restriction

At the heart of the work of thermostators - physical laws. Therefore, you need to remember that the conditions in which the device is located can be made some adjustments (for example, remoteness from the heat source). There are approximate tables of compliance of the regulator scale and temperature, which can be taken beyond the landmark when installed. However, after the main setting it will be necessary to "understand" its thermostat.

For this:

  1. Exhibit the temperature on the handle with the labels.
  2. An hour later, control measurements are conducted by a room thermometer at several points of the room.
  3. If the temperature is greater or less, the testimony is adjusted on the handle.

The proportionality zone is 2 ° C. If you set a temperature of 20 °, the device will hold the indicators ranging from 20 to 22 ° C.


Sensor after installation on the radiator

Two pin, which are included in the sensor, help set limitations of the minimum and maximum position of the thermoelement.

They are at the bottom of the device:

  1. To set a limit on a mark, for example "3", you need to pull the limiter and set the sensor readings at the "3" mark. The pin is then inserted into that hole, which in this position turns out to be under the rhombus icon.
  2. The second restrictive threshold is exhibited in the same way. The handle turns to the desired indicator, only the pin is inserted into the hole, which appears under the triangle icon.
You can block the regulator at a certain temperature (protects from the inadvertent failure or children's pranks).

For this:

  1. Both pins are removed.
  2. The handle is put on the desired indicator.
  3. In this position, the first pin is inserted into the hole located under the rhombus.
  4. The second pin is in the hole under the triangle.

Danfoss thermostators have many positive feedback. This is a very easy-to-use device that does not require any attention after the initial installation and settings. But the result will be more comfortable temperatures in the apartment, as well as in some cases, significant savings budget funds.

Selection of thermostators for heating radiators

The thermostators installed on heating radiators allow you to increase the comfort of indoors, and also significantly save on heating, if it comes to a private house.

There are several types of devices on the market: electronic, mechanical, gas-filled, liquid, as well as remote or built-in thermal sensors. Our material is dedicated to how to choose and install thermostators to pay attention to first.

Types of regulating elements


Electronic Automatic Danfoss Temperature Management

Installation of a shut-off-regulating crane or a valve in front of the heating radiator - a measure that serves not only to adjust the flow of water into the battery, but also a question of emergency safety, because it becomes possible to turn off the battery from a common riser if necessary. Such a simple and important function was previously not always provided for in heating systems, by the way, not in all new houses installed locking valves on batteries.

As locking and regulating elements are used:

  1. ball crane
  2. cone valve
  3. automatic thermostat.

Ball crane

This is the most minimal measure aimed at creating the ability to disable radiators. This element only performs a locking function, since only two positions are provided with the design - "open" or "closed".

Adjust the heating of the battery with the help of a ball crane is an inefficient practice, since the crane that stands in the middle position is vulnerable to the destructive action of solid particles. The coolant circulating in the system contains suspension, rust particles and other foreign minor elements (especially this is characteristic of heating systems of apartment buildings).

Gradually, the surface of the crane will be collapsed, removal remains on the shut-off ball, and it means sooner or later it will become not suitable for performing its main function - locking, because the tightness will be broken.

Cone valve

Allows you to adjust the receipt of the coolant into the radiator, so it can be adjusted to the temperature. In general, the installation of a manual cone valve in front of the batteries is inexpensive and functional solution.

The disadvantage in this case will be the complete absence of any marking for adjustment, you will have to determine how to change the position of the valve, do not forget to return it to the original position and so on.

Temperature regulators with thermostat

The most modern and comfortable solution is to install in front of the thermostat radiator with a thermostat that allows you to accurately adjust the degree of heating of the battery, which means that the air temperature is indoors.

Types of thermostators

To date, two types of thermostators are applied:

  1. Liquid
  2. Gas-filled

Thermostat design


Device and main thermostat nodes

Thermostat for the radiator has two parts:

  1. Valve
  2. Thermostatic element

The thermostatic element is a hollow cylinder, the walls of which are corrugated, this cylinder is called a bellows. The bellows is filled with substance (water or gas), which can react to air temperature fluctuations in the room.

When the temperature rises, the volume of the working substance increases, presses on the walls of the bellows. The bellows moves the rod that shifts the valve. The valve controls the amount of coolant incoming to the battery. When the valve rod moves, the receipt of the coolant decreases.

Connecting radiators - detailed schemes and practical recommendations


The photo shows the types of thermostat

If the air temperature indoors decreases, the volume of the working substance decreases, it no longer stretches the bellows, thereby opening the valve and increasing the flow of the coolant.

The bellows have a large margin of strength and working resource, they can withstand hundreds of thousands of compression cycles for decades. (The Danfoss company cites the data that their bellows are able to work up to 100 years, passing 1 million cycles).

Gas-filled thermostators

Gas-filled thermostators are produced by the Danfoss Danfoss (Danfoss) company, it is a reliable equipment that has more than 20 years of service. The bellows system of the gas-filled thermostatic element, as indicated above, is filled with gas, it allows you to smoothly adjust the air temperature in the room.

The sensor determines the ambient temperature. Each temperature corresponds to a certain level of gas pressure in the bellows, which is backed by the compression of the adjusting spring.

With an increase in the room in the room, the gas pressure in the bellows grows, and the valve cone is shifted towards the closure. This process is due to the gas pressure in the bellows and the springs compression, the balance will not be restored. When the air temperature drops in the room, the gas pressure decreases, as a result of this, the bellows is compressed, and the valve cone is shifted towards the opening until the equilibrium is reached.

Danfoss devices


Examples of models of automatic thermostators Danfoss

RTD series thermostators from Danfoss is gas-filled devices.

Such technical execution gives two serious advantages at once:

  1. Gas is condensed in the cold half of the sensor, which is further from the control valve. In this case, the radiator thermostat will always determine the temperature fluctuations in the room, and the effect of water temperature in the pipe will be excluded.
  2. The thermostat is very sensitive and is capable of extremely quickly responding to a change in temperature, so the most effectively controls the flow of heat into the room.

Danfoss company produces two types of thermostators for radiators:

In addition, they can be in a straight or corner performance.

The type of regulator is selected based on the type of heating system in the house, and the valve size is the magnitude of the diameter of the pipe, supplying the coolant or by the diameter of the hole in the heating instrument's tube.

RTD-G valves in thermostats are used:

RTD-N valves in thermostats are used:

  • For two-pipe heating systems in the new building;
  • For two-pipe heating systems of cottages in which circulation pumps are installed.

Installation of regulator

The process of installing thermostators on the radiator in the house is not complicated, if desired, it can be done with your own hands. If there is no experience or desire, you can always turn to professional installers.

Video Instructions for installing the thermostat for the radiator on the example of the automatic electronic regulator Danfoss Living ECO:

The sequence of actions will be the same, regardless of metal, from which the batteries are made, the principle one and for aluminum and for bimetallic radiators.



Removing the old collar

Installing a new collar

It is necessary to install a new set of metal collar and a deaf nut on copper pipe, old are dismantled. If the collar cannot be removed, then its parts are neatly cut out with a small screwdriver, after which they can be torn apart from each other. Since it is necessary to work with a screwdriver and hacksaw directly and the pipes should be kept attentiveness.


After completing the installation, adjust the desired temperature on the thermostat.

Usually for living rooms or passing premises, the regulator is left completely open, for sleeping rooms you can half-handed it. If in different rooms At home - different settings of thermostators, then you should keep the door to the rooms with closed, otherwise the device will incorrectly determine the air temperature in the room and try to align it.

What to choose: gas or liquid?

This question is perhaps one of the most frequently discussed among consumers and installers. Technically, the bellows filled with gas faster react to fluctuations in air temperature fluctuations. In this case, liquid devices are more accurate when transmitting the internal pressure of the bellows on the movable mechanism.

Thus, it is difficult to answer unequivocally which bellows are better. When choosing, first of all, it is necessary to focus on the quality of manufacture, warranty and service life. This means choose from products of proven manufacturers, technical solution It may be secondary in importance.

Advantages of Danfoss thermostatic regulators

  • Danfoss thermostats for radiators have a number of benefits:
  • The body of the device has a modern ergonomic design;
  • A high-quality and concise appearance will allow them to fit into any interior;
  • Thermostats can be installed on existing heating systems;
  • Do not need prevention or maintenance;
  • Not whimsical, can work in the conditions of domestic heating systems;
  • Has a long service life;
  • Provide accurate temperature adjustment in rooms (6-26 degrees);

Benefit from installing thermostats


Electric thermostat for heating radiator

When installing thermostators on radiators in a private house or cottage, saving on heating up to 20% is achieved. This is due to the reduction of excess heat consumption during the periods, when it is not necessary - warm and sunny days, with the operation of electrical appliances, and so on.

The thermostat allows you to maintain a healthy microclimate in the rooms, since the air does not overheat. It provides comfort in the house, protects against sinking wooden furniture and extends the service life of sensitive technology.

For some types of fuels used in private homes and cottages (for example, diesel fuel), the cost of installation of thermostators will be compensated for one heating season.

Save the owners of apartments is unlikely to succeed. But an important profit will be a comfortable environment in the rooms.

Types of thermostatic elements

There are two types of thermostatic elements:

  1. Thermostatic element with built-in sensor
  2. Thermostatic element with remote sensor

Built-in temperature sensor


Remote temperature sensor

Built-in sensor requires free air circulation around itself. This is necessary to prevent heat from the pipe. To avoid unwanted heating, the sensor is installed horizontally.

Remote sensor

  • Remote temperature sensor is used in the following cases:
  • If the radiator (respectively, the thermostat is set to niche;
  • If the regulator is located less than 10 cm from a wide window sill (more than 22 cm);
  • With the radiator depth of over 16 cm;
  • If the axis of the thermostatic element is in a vertical position;
  • If the radiator is closed with dense curtains.

In these and some other cases, a remote sensor should be installed, since the built-in will not be able to work correctly.

The sensor must be installed perpendicular to the radiator body. Since in the case of a parallel installation, its testimony will be shot down by the action of warm air raising from the radiator.

Conclusion

When choosing radiators, thermostators and in general, the heating system should be referred to specialists. It is preferable to deal with professional companies, as they bear legal responsibility for the quality of the work performed and the equipment sold.

Not a small role is also played by the warranty and warranty service.

Savings, when using individuals' services, often increasingly comes out of all works, and the cost of eliminating the consequences of the accident in the heating system may be very impressive.

Thermal heads Temperature controls for danfoss heating batteries

The heating system is one of the most important details Any house. Unfortunately, it is for her who goes and the greatest costs during the payment of utility payments, and independently of the established autonomous or centralized heating. Get a comfortable temperature and significantly reduce the costs of paying bills for the consumed heat energy help thermostats installed on each radiator battery. Effect can be obtained by installing temperature regulators for Danfoss heating batteries capable of 1 degree to maintain the required temperature in the room.

Principle of operation and design

Danfoss thermostats are necessary to maintain the room temperature. In the process of operation, thermostators track the temperature change in the room using the built-in heat sensors. When the temperature drops, the thermocontrol system opens the fence of the coolant, increasing its volume and circulation inside the battery. After reaching set temperature, Danfoss thermostat reduces the flow of the coolant, thereby reducing the heating temperature and energy consumption in the heating device. Equipment consists of two main components:
  1. Thermostatic element is responsible for controlling the device.
  2. Valve regulating the return of the coolant into the radiator. Performing element.
A small corrugated cylinder is installed in the thermostatic element filled with a liquid or gaseous component reacting to the slightest change in air temperature. In some models, as a thermostat, a metal plate made made of heat-driven material is used, but thermostators for Danfoss heating radiators with gas filling of the bellows are considered the most accurate. The temperature control system can be mechanical or electronic. Temperature controllers for danfoss heating batteries with electronic setup are equipped with a small display to display information about the entered program.

Differences of some models

Depending on the model, the installed thermostat can be divided according to the principle of operation and constructive features.
  • Supported temperature ranges from 5 to 30.
  • Option of temperature measurement sensor - it can be built-in, remotely controlled and programmable.
  • Different in the installation type - angular, straight, for the lower or top-type connection.
Live heat regulators are most popular battery Danfoss.Their design allows you to connect batteries from the bottom, top and side liner. The only thing to take into account is the length of the shut-off valve and, accordingly, select the length mounting pipes. The possibility of implementing any type of connection is carried out due to the rod located along the shank axis. Model designation of such equipment RTD-N UK. The wide range of valve installations of the UK model, allow them to be used in conjunction with Danfoss convectors built into the floor. Harl thermostators are attached directly to the point of fence of the coolant radiator and require minimum of additional installation work, do not occupy an excess place. Such sensors are labeled as RTD - N or RTD - G, depending on the model. Increased bandwidth It gives the opportunity to use thermoclap in closed and open heating systems. Another type of temperature regulators for Danfoss heating batteries is an embodiment in the radiator. Such equipment is widely used in compact devices located in niches, close to side surfaces. Often embedded valves are equipped with remote thermostators.

Installing and Setting the Sensor

Installing automatic thermostators for Danfoss radiators, instructions should be clearly followed. It is not recommended to place the head of the regulator for bulk objects, behind the curtains or inside the niche. This will lead to distorted measurements, as a result of creating obstacles to uniform air flow around the sensor. If the installation of the thermal heads for Danfoss RTD 3640 radiators or other similar models is impossible due to the hidden battery location, it is necessary to take care of an external remote sensor.

Despite the possibility of mounting thermostators, in almost any heating system, jointly use them with cast-iron batteries Do not bring the expected results due to slow cooling and slow heating of the battery.

The installation of the thermostat should be carried out only by professionals, in order to avoid further problems and improper functioning. The setting of temperature regulators for Danfoss heating batteries is carried out once, at the beginning of each heating season. For proper setting It is necessary to reduce the heat loss of the room as much as possible, for which the windows and doors are closed. Then a regular room thermometer is installed in the center and opens as much as possible. stop valve Temperature regulator. After the room temperature will be somewhat exceeding the one you consider the most comfortable for yourself, the valve must be completely closed. In the process of gradual cooling air, the temperature will begin to decline and as soon as it reaches the thermostat you need to be gradually open until the coolant is in the system. Usually, just audible as water or other liquid coolant begins to circulate inside the radiator. For sensors equipped with electronic adjustment, it is sufficient to simply select the desired heating temperature and fix it in the program. If necessary, the temperature is easily changed directly during the work. After the completion of the heating season, the radiator temperature regulators of heating radiator Danfoss is recommended to be left in the maximum open position, for circulation inside the valve and reducing the possibility of a blockage.

The cost of heating and ventilation averages 30-50% of the family budget. And the problem is not in the function itself, but in poor-quality energy spending. Convenient solution Offered Danfoss - thermostat to control the temperature in the house and the operation of the heating system. This device can be applied in combination with almost all boilers, including heating devices with a liquid coolant.

The thermal head of the house, in the apartment, industrial premises, warehouses, closed greenhouses and greenhouses, in a word, wherever relatively constant temperature regime is required. Moreover, this applies not only heating, but also air conditioning. So, the thermal head is equally successfully interacting with air conditioning, refrigerated equipment and other aggregates responsible for temperature.

Constructive features

The main purpose of the Danfoss thermostat is to long-term maintaining the temperature-selected temperature regime. The design of the device includes two main details:

  • the thermostatic element or how else is called - thermostat;
  • valve.

The valve is first mounted on the battery and only the thermostat is already installed on it. It is the second element that is the main thing in the design of the device. It seals the ambient temperature, after which it gives the required signal to the valve, which in turn opens or covers the coolant stream.

In the inner region of the Danfoss thermostat, there is a bellows - a corrugated container filled with gas or liquid. When exposed to temperature, the filler begins to change the dimensions and apply to the shut-off valve. When overlapping the coolant flow in heating units, the temperature indicator begins to increase.

If the room is highly cooled, the filler is compressed and the reverse reaction is formed - the chamber pulls the spool rod, which in turn opens in the valve element the clearance for the receipt of the coolant in the valve element.

The company produces two varieties of thermostat - on gas and liquid. But the second option is considered more inert, it significantly slowly gives a signal to change the temperature regime.

Varieties and conditional designations of devices

The type of filler and purpose is determined by the following abbreviation:

  • RTS - Liquid Silphon

  • RTD-G - gas device for a single-tube or two-pipe system in which there is no pump

  • RTD-N - gas device For a single-tube, two-pipe pumping system

In some models, in addition to the main function, there are a number of additional options. For example, an interference protection program in the set settings by random persons. The option will be convenient for installation in public institutions or children's institutions. The number of modes and varieties of functions differ depending on the selected modification.

Model range of devices

The company produces a wide enough the lineup Danfoss heating temperature regulators.

The most popular variations are considered:

  1. Danfoss RDT marking 3640 - the device is designed to use on the heating systems of a two-pipe standard type. It is equipped with an RTD option, excluding the line of highway in the cold season. Used in domestic, industrial conditions. It has four divisions with the designations in the form of Roman numbers.
  2. The Danfoss RAX regulator is a liquid type of appliances that is used for installation on designer-type radiators or towel rails. It has attractive external parameters and minimalistic style. Only divisions with Roman or Arabic figures are present on the housing.
  3. Living Eco with microclimate tracking function in the house. This is an improved series, which is successfully applied in commercial institutions and residential buildings. The peculiarity of the thermostat for the heating radiator is that it has a liquid crystal screen that reports all the necessary information about the coolant. Also on the case there are three main modes setting keys.
  4. The Danfoss RA-299 gas device with automated temperature control is produced in several color solutions. It quickly reacts to temperature change. It is used exclusively for equipping traditional heating systems.
  5. 013 G4 001-013 G4 009 - Multifunctional series of devices, suitable for both heated towel rails and various sections of the heating device. There are left and right-hand type.

Each of the presented options is completed with the details that simplify the mounting of the device and its subsequent use.

Installation of thermal heads

The Danfoss thermostat is installed directly on the hot tube, which supplies heat carrier to the household heating system. Mounting work Do not have any difficulties, even if it concerns design variations, the principle of installation in all the same.

It is necessary to follow the following steps:

  1. Marking on the feed pipe to determine the area you want to cut. At the same time, take into account the dimensions of the valve body and take the threaded element to enter directly into the pipe.
  2. Disconnect the heating and lower the water so that in the process of work do not flood the house.
  3. By markers, cut the unnecessary pipe of the pipe and make a thread with a dice on the outer part of the cut.
  4. The connecting part is treated with a special plumbing paste of any manufacturer and waist.
  5. On the thread, which was made by a rash, screw the valve element, after which tighten the washer well. Additionally, sealing the area of \u200b\u200bthe joint is no longer required, this compound will be enough for the pipe to not leakage.
  6. Remove the fuse, set the maximum "5" maximum indicator on the thermostat and above the end of the housing with the scale. The cap is put on to the stop, the decisive signal service a ringing click, it indicates a dense contact of the parts.
  7. Check all connections and connect the thermal device back to the overall heating system.

Check the functioning of the Danfos regulator to the first opening and closing the valve device. If the installation was carried out according to the rules, there should be no problems.

How to adjust the device

Although all modifications danfoss thermostators and have differences on external parameters, technical characteristicsThe device setting is done by the same method. To make it necessary to refer to the instruction manual and study the designations of the modes indicated on the device case. Indicators may have differences, depending on which model is used.

Next, install the desired temperature mode on the machine. To do this, move the torque to the desired mode. If a device with a button control was installed, all manipulations are carried out by pressing the "Add" or "down" keys to the "Add" keys.

You can also select an intermediate parameter if it is more suitable for creating a specific microclimate in the house. After a few minutes, the heating system is adjusted for selected values \u200b\u200band will reproduce the heating of the room until the desired microclimate is obtained. The valve and refrigeration units are configured in the same way.
