Parameters and advantages of thermostats from Ballu. Mechanical thermostat: types, principle of operation, installation. Thermostats for heating boilers Features of connecting the thermostat to an infrared heater

With the onset of cold weather, many begin to think about additional heating of their homes. Since with the beginning heating season, as a rule, begin renovation work in places where heating mains break. Or do you have thoughts of switching to electric heating, as an additional alternative for country house. In this article we will talk about a temperature-controlling device - a thermostat, namely, we will talk about how to install and connect the thermostat to infrared heater.

Installation nuances

We will not go into the types and types of regulators, or arrange comparisons and tournaments. All of them are good in their own way and will fulfill their purpose, serving faithfully. The first thing you want to pay attention to is the installation location. Doesn’t depend on what type of heaters you have: infrared, panel, convection.

Installation of a thermostat with an air temperature sensor is prohibited in the following places:

in close proximity to heaters;
in places where there is a draft;
in the heating zone of infrared emitters.

All these places are unsuitable for placing a thermostat, since when located near the heater, the air next to it will heat up to the desired temperature earlier, which will lead to false operation, as a result of which the room will not heat up to a comfortable temperature.

If you install the thermostat in the heating zone of the IR heater, its body will heat up earlier and distort the sensor readings. In places where there is a draft, the sensor will not show desired temperature and heaters will overheat the room, consuming excess electricity. The height of the temperature sensor should be placed in the comfort zone, at a level of 1.5 meters from the floor.

Connection diagrams

Always, before installing and connecting the thermostat, read the instructions and passport data for the device. Since the manufacturer indicates the required cable cross-section and provides a connection diagram for its products. If you deviate from the requirements and save on wires and thermostats, there is a high probability of equipment failure or fire hazard.

Connection diagram of the thermostat to an infrared heater with a power of up to 3.5 kW:

If the room is heated by a group of heaters up to 3.5 kW, then the connection diagram will look like this:

If you are the owner of a three-phase network and heating is carried out by a group of heaters with a total power of more than 3.5 kW, then a magnetic starter is added to the control circuit, which is controlled by a thermostat:

This is the principle used to install a temperature controller. As you can see, there are some features in installing and connecting the thermostat, so it is important to first read the instructions from the manufacturer and then proceed with the main process.

Thermostat Ballu BMT 1 — special device, with the help of which the amount of heat transfer from the infrared heater is regulated. Its connection allows you to significantly reduce energy consumption when operating the heating device.

In addition, having the function of setting a certain temperature in the room, The thermostat provides comfortable temperature under changing external conditions.

The advantages of such a device include the possibility of its operation without power supply, and the disadvantages are that the temperature is controlled within 0.5-1°C.

1.4 Electronic devices

Such devices are equipped with a temperature sensor, the operation of which is based on reading certain frequencies electromagnetic waves. In this case, you can obtain temperature data external environment and directly in a heated room.

The control unit, having received data from the temperature sensor, regulates the operation of the heater in accordance with the program using a specific algorithm. The signal processing circuit is provided by the manufacturer and may have many control options depending on the parameters specified by the user.

To the advantages electronic device relate:

high accuracy— 0.1°С;
autonomy - the ability to program for a long time without further user intervention.

As a disadvantage, we can highlight dependence on a third party.

2 Connecting the thermostat to the infrared heater

Exact connection diagram for models different types included with the device being sold.

And the installation itself is carried out in accordance with the following principles:

Separate wiring is laid to the location of the thermostat, which is connected to the “zero” and “phase” terminals;
the installed thermostat is connected to the infrared heater by a separate line;
in the presence of external sensors that determine the temperature environment, they are connected to the controller via a dedicated line or wireless connection.

2.1 Gas infrared heater BIGH-55 (Galaxy)

The BIGH-55 gas heater is an autonomous heating device that can be installed anywhere, as it does not require a permanent connection to the electrical network. It does not use electricity at all.

BIGH-55 is used for heating both premises (country house, dacha) and open spaces(open areas of cafes, restaurants, hotels).

Main characteristics:

propane (propane-butane) is used as a coolant when burned, heat is released;
thermal power at maximum heating - 4.2 kW;
The heater is designed to heat rooms up to 60 square meters. meters;
gas consumption depending on operating mode - 110, 207, 305 grams per hour.

At overall dimensions 420×720x360 mm gas heater BIGH-55 weighs only 8.4 kg.

One of the features that distinguishes the BIGH-55 gas heater is the ability to use two types of heat transfer - infrared and convective. The direct source of heat is a special panel made of high-quality durable ceramics, which is located in the front of the heater.

Convective heating occurs due to the release of air heated in the housing through the perforation in its upper part.

The BIGH-55 gas heater can operate in three main fixed modes, in which a sufficient amount of heat is released with a reduced or increased amount of gas consumed.

Gas heater BIGH-55 equipped with a reliable multi-level security system during operation. Flame control is carried out by a protective thermocouple. Individual sensors react by turning off the system when the quantity is exceeded carbon dioxide in the surrounding atmosphere and overturning. The gas cylinder is secured with a special lock that prevents it from falling out when moving the heating device.

During operation, the gas infrared heater does not produce any noise. Its installation and connection do not present any difficulties, since the gas pressure reducer and hose connecting to the cylinder are already included in the delivery set. The heating device itself is equipped with a special chassis that allows it to be easily moved along a horizontal surface.

The BIGH-55 gas heater can be connected to a cylinder with a capacity of up to 27 liters, which at maximum load will allow the device to operate for 38 hours. In this case, the most will be spent a large number of gas But since the device has two more modes (more economical in consumption), Then the heating time can be increased from 3 to 5 times.

The BIGH-55 infrared heater, unfortunately, burns oxygen during its operation. Therefore, when installing such equipment in enclosed spaces, regular ventilation is required to avoid oversaturation of the air with carbon dioxide.

Domestic gas cylinders are suitable for this heater model. The minimum volume (size) of one cylinder can be 5 liters (2.5 kg of liquid gas). The largest cylinder that can be connected to the heater is 50 liters (21.2 kg of liquefied gas). In the first case, at maximum heat transfer, the device can operate uninterruptedly for 8.5 hours, in the second - 70.5 hours. When periodically changing operating modes, the heating time increases significantly.

Operation of modern climate control equipment cannot do without the use of thermostats. These are small devices thanks to which the user can control microclimate parameters. In particular, such devices are used in sets of underfloor heating systems, air conditioners, boiler stations, etc. Today you can find a variety of device versions on the market of accessories for heating systems, but a mechanical thermostat is considered the most affordable, simple and reliable solution in this segment.

How the device works

Classical models of this type work on the principle of changes in the structure of certain substances against the background of an increase or decrease in temperature. In this case we're talking about O gas mixtures, enclosed within the structure. Under the influence of temperature fluctuations, the filling volume of the section containing the active substance expands or contracts. These processes act on the sensitive membrane, making appropriate adjustments to the readings. At the same time, the mechanical one serves not only to reflect the current temperature regime, but also allows the user to configure the device to a certain work program. Advanced control relays, for example, can be programmed, although this operating principle still applies mostly to electronic models.

Varieties

The main feature of the separation of models of this type is the installation method, although it is not the most important from the point of view of operational nuances. Nevertheless, the manufacturers themselves distinguish between wall-mounted and hanging devices. That is, the first ones are integrated into a wall niche and practically merge with the surface, while the wall-mounted ones can be mounted in a rack or a special load-bearing structure. Again, in terms of operation, the presence or absence of a sensor for monitoring microclimate parameters is more significant. A typical mechanical thermostat contains the very substance that determines the temperature regime directly in its housing. However, in modern models Even the mechanical type is becoming more and more common and a remote method of monitoring microclimate parameters. This means that the thermostat is divided into two components: a sensor that records the temperature readings at the location where it is installed, and a control relay.

Features of models for boilers

Household appliances are considered one of the most complex units in the heating equipment category. Consequently, the thermostat must work with a wide range of operating parameters. Moreover, it is in boiler maintenance that two- and three-channel models are often used. They allow separate control not only different parameters, but, in fact, also devices. An illustration of this approach can be a device that simultaneously controls the functions of the boiler itself in the form of a combustion chamber, and in separately- boiler room water heating installation. In addition, thermostats for heating boilers are often produced with remote sensors and programming capabilities.

Main characteristics

There are several characteristics to consider when evaluating the appropriate thermostat settings for a particular application. The base will be the maximum load power, but the same thermostats for heating boilers with an indicator of 3.5 kW are quite suitable for the most powerful household unit, so there are no particular difficulties in this choice.

It is much more important to calculate the optimal temperature ranges with which a particular modification can work. For example, most indoor units have a scale from 0 to 40 °C. But if necessary, you can also find versions that cover the negative range by an average of 10-15 degrees. Another important parameter- This is the material of the body. Typically, a mechanical thermostat is made of plastic, but for harsh operating conditions it is worth considering the possibility of using a metal model, although it is heavier and, as a rule, more expensive.

Thermostat manufacturers

The market offers enough solutions for any need, including boiler control requirements. In particular, the mechanical thermostat TDC 1 from the manufacturer Ballu has proven itself with the best side thanks to functionality, reliability and high-quality assembly. True, this model has a rather narrow range of operating temperatures from 10 to 30 °C, so it may not be suitable for every boiler.

More ample opportunities Temperature control is offered by Electrolux in its Basic ETB line. It is also worth paying attention to offers from the companies DEVI, HEAT-PRO, TIMBERK with TMS modifications, etc. But, if we discard the temperature scale, the standard Ballu mechanical thermostat will outperform its competitors due to its low price tag of 700 rubles.

How to install the device?

First of all, they are produced preparatory activities, which may involve creating a niche in the wall like a rosette. Next, the cable wiring is laid. It is important to consider that, in addition to connecting the main power line, the device must be interfaced with the equipment. Another thing is that the same wiring can be avoided by purchasing a wireless model. For example, modern convectors with a mechanical thermostat are already equipped with radio devices in basic configurations, relieving the user of unnecessary hassle with installation. But not all units support the wireless principle of interaction with control equipment, and this nuance must be taken into account in advance. The same applies to the method of installing the remote sensor, which will also require careful preparation of a special point for fixation. Another thing is that the sensor will not require intervention in the wall. For it, it is enough to prepare a mounting bracket on which a small case will be mounted. All necessary fittings this kind is usually included in basic thermostat kits.

How to use a mechanical thermostat?

Immediately after installation, it is necessary to turn on the equipment at the optimal temperature for the medium range. You should not expect to quickly achieve the required parameters - for a boiler, for example, this may take several hours, depending on the version. Further operation will depend on the capabilities of the device itself. For example, the simplest mechanical room thermostat only assumes the ability to turn on/off with the desired setting this moment mode. More technologically advanced models can be configured for a week or even a month of operation with automatic changes in performance indicators depending on the weather outside or time of day. This technique works like “smart home” components.

Conclusion

Given the general transition to digital technology, it may seem strange to purchase a mechanical device. But there may be serious reasons. First of all, the very independence of the device from the electronic operating principle adds to its reliability. In addition, models of this type are cheaper and are not as sensitive to electrical faults. The same convectors with a mechanical thermostat will not suffer in the event of a power surge or network overload. But it should also be taken into account negative factors such a choice. Among the disadvantages of mechanics, experts include an error of 2-3 degrees and the sensitivity of the filling to physical influences. For example, even a slight blow can affect the accuracy of readings in the future. But for the sake of fairness, we should also note the desire of manufacturers to minimize these disadvantages. This is evidenced by the increase in accuracy due to the use of modern element base, and the supply of housings with additional protective coatings with water-repellent and shockproof materials.

What is a thermostat and what is it for?
A thermostat is a device with which you can set the required temperature in a room. The thermostat has a built-in air temperature sensor. That is, when the set temperature is reached, the thermostat turns off the device, and when the temperature drops, it turns it on. This allows you to maintain a comfortable temperature automatically.

How to disassemble the Ballu BMT-1 thermostat?
Disassembly is very simple. Unscrew the connecting screw from the end of the thermostat housing and disassemble it into two parts. Next, connect the thermostat to the network and the heater according to the diagram.

Where and how is the Ballu BMT-1 thermostat installed?
The Ballu BMT-1 thermostat is installed on the wall, at a height of 1.2 - 1.5 meters from the floor level. The thermostat is overhead, so it is screwed to the wall with simple self-tapping screws. The thermostat should be installed in a place where there are no drafts or direct sunlight. This is necessary for the correct operation of the temperature sensor installed in the thermostat.

How to connect a heater to a thermostat?
To connect the thermostat, minimal electrical knowledge is required. The Ballu thermostat is connected according to the diagram that is included in the instructions for the heater or thermostat.

How many heaters can be connected to the Ballu BMT-1 thermostat?
The Ballu BMT-1 thermostat has a maximum permissible current of 16 A. This means that it can withstand a total power connected to the thermostat of 3500 W. For example, you have 3 1000 W heaters in the room, which means you will need 1 Ballu BMT-1 thermostat.

The temperature in my room does not match the temperature set on the thermostat. Why?
This can happen for various reasons.
If the room temperature is significantly lower than the set temperature after the heaters have been running for a long time, this may mean that you do not have enough power installed heaters. It is necessary to change the heater to a more powerful one or add another heater.
Another reason for such a temperature discrepancy may be that the thermostat is exposed to direct sunlight or currents warm air. The temperature inside the thermostat turns out to be higher than the air temperature in the room, which leads to incorrect operation.
If the room temperature is higher than the set temperature, the reason may be drafts in the area where the thermostat is installed, or a cold, frozen wall on which it is installed.
Also, do not install the thermostat at an angle to the left or right. The ventilation openings must be strictly at the bottom and top and must not be blocked by anything. Otherwise, errors in the set temperature may occur, both higher and lower.

I want to put heaters on the balcony and control the temperature on the balcony from the room. How to do it?
To solve this problem, you should use a thermostat with an external temperature sensor. Ballu BMT-1 has a built-in temperature sensor and therefore this model of thermostat must be installed in the room where it is necessary to regulate the temperature.

The Ballu BMT-1 thermostat does not have an “on/off” key, what should I do if I want to completely turn off the heater?
In this case, there are several options. One of them is to make a plug at the end of the wire and turn the heater on or off from the outlet. You can also place a separate switch next to the thermostat or make a connection from a separate circuit breaker so that you can turn off the heater regardless of the temperature in the room.

Which thermostat is better, mechanical or electronic?
Electronic and mechanical thermostats have their pros and cons.
The electronic one has a built-in thermometer, which allows you to measure the temperature in the room. A mechanical thermostat does not have a thermometer. It only contains a regulator that turns the heater on and off depending on the set temperature. Therefore, if accurate temperature measurement is necessary, it is better to use an electronic thermostat.
A mechanical thermostat is more resistant to voltage surges. Therefore, in rooms where there are power surges, it is better to use a mechanical thermostat.

My heaters are in different rooms, can they be connected to one Ballu BMT-1 thermostat?
Technically, there are no obstacles to such a connection, but since the temperature sensor is installed inside the thermostat, it will be correctly regulated only in the room where the thermostat is installed. The other room may either be too cold or too hot.

If I have large room, and I want to connect heaters to one Ballu BMT-1 thermostat, and the total current of the heaters is more than 16A, what should I do?
If the total current of the heaters is more than 16A, then it is necessary to use a magnetic starter (contactor). The magnetic starter is selected based on the power of all heaters that you want to connect.

What is a magnetic starter and how is it connected?
An electromagnetic starter is a relay (contactor), which is designed to control high currents. The connection goes from the heater to the magnetic starter, and from the starter to the thermostat. It is necessary to connect according to the diagram that is included in the instructions for the heater.

Does the thermostat make any sounds when operating?
When the set temperature is reached, the Ballu BMT-1 thermostat produces a characteristic soft click, which indicates that the thermostat is turned on or off.

The thermostat for an infrared heater calibrates the heat output of the heat-generating device, reducing the consumption of expensive electricity to the lowest possible level.

And such a regulator also sets the level of heating of the room, providing the opportunity to obtain the most comfortable temperature. Therefore, not a single infrared heating system can do without such a detail.

Mechanical thermostat Ballu BMT-1 for infrared heater

How does a thermostat work?

Such a regulator consists of two main components:

Temperature sensor installed near a heat source and/or in a heated room.
Control unit , which processes the signals from the temperature sensor.

These structural elements interact with each other according to the following scheme:

The control unit receives the heater operating program, which indicates the temperature in the room or the degree of heating of the heating element.
The temperature sensor reads the “degrees” in the room and/or at the heating element, transmitting this information to the control unit.
The control unit includes a heating element in the event that the temperature transmitted by the sensor is less than the programmed value. And turns off the infrared panel if the temperature in the room or at the heating plate exceeds the programmed parameter.

As a result, ceiling and wall infrared heaters with a thermostat consume only the required “volume” of electricity, warming the room only to the desired temperature. In this case, calibration of heat transfer and temperature is carried out in steps of 0.1-1.0 °C

Typical types of thermostats

Modern manufacturers produce two types of thermostats:

Mechanical devices. Such regulators use a special plate or diaphragm made of a temperature-sensitive material as a temperature sensor. Therefore, thermomechanical regulators, in fact, do not have a control unit. The plate closes or opens the contacts of the electrical circuit powering the infrared heater, under the “influence” of the actual temperature in the house. And all regulation consists of fixing the set temperature using a mechanical lever, with the help of which the elements of the plate temperature sensor are positioned.

The main advantage of such a regulator – the ability to work without supplying electricity to the device.
Main disadvantage – low calibration accuracy – from 0.5 to 1 °C.

Connection diagram of an infrared heater to a thermostat

Electronic devices. The temperature sensor of such a device detects thermal radiation by reading electromagnetic waves of a certain frequency. At the same time, both the temperature “overboard” and the degrees in the house are controlled. The control unit of such a controller receives signals from the sensor and processes them according to a built-in algorithm (program). Electronic devices have only digital controls. The algorithm for processing signals from the sensor is set using factory programs or buttons on the case. Information about temperature and operating modes is displayed.

The main advantage of such a device – high accuracy – calibration is carried out in steps of 0.1 °C. In addition, there is some control autonomy. For example, infrared heaters with a thermostat for a summer residence can be programmed to operate for a week based on the air temperature outside the house and not even leave the country to monitor and adjust the operation of the heating system. Mechanical regulators cannot do this - the user will have to “turn the adjustment wheel” almost every day.
Main disadvantage – work only when there is voltage in the network.

When installing a thermostat, you need to follow the following generally accepted rules:

A separate regulator is installed in each heated room.
Between temperature sensor and supporting surface you need to install a heat-reflecting screen.
Infrared ceiling heaters with a thermostat cannot be more powerful than 3 kW.
The recommended placement height is 1.5 meters from the floor level.

The installation of the device itself is carried out as follows:

A separate line is “pulled” from the central panel to the regulator, which ends at the incoming “zero” and “phase” terminals.
A power supply line is drawn from the regulator to the heater, starting from the outgoing “zero” and “phase” terminals.
External temperature sensors are connected to the corresponding connectors of the thermostat, connected to the regulator using separate lines or wireless communication protocols.

Exact installation diagrams are given in the data sheets for specific models of control devices.

Thermostats for infrared heaters are necessary for control and automatic maintenance set temperature in the room. It’s hard to imagine without this device effective work modern heating equipment.

The thermostat controls and maintains the set room temperature

The principle of operation of the thermostat

The thermostat works cyclically, using the opening and closing of the electrical network: it turns on and off depending on the signals that the temperature sensor or biomechanical plate sends to it.

As the temperature rises, the resistance of the sensor decreases. As soon as the resistance reaches the desired level (equal to a certain temperature), the thermostat turns on and opens the circuit. Next, the sensor gradually cools down, its resistance increases, which again leads to the operation of the thermostat and the closure of the circuit, i.e. connecting an IR heater. This principle of operation applies to all types of thermostats, regardless of their filling.

Types of thermostats

Thermostats are divided according to the installation method: open or hidden. Another criterion for classifying devices is the design of the working fluid: solid, liquid or air.

Also, regulators differ in the temperature regime of operation. There are the following types of thermostats:

high temperature - 300-1200 ºC;
medium temperature - 60-500 ºC;
low temperature - less than 60 ºC.

In terms of design, regulators are of two types:

Simple - mechanical and electromechanical models, which differ low cost and limited ability to accurately control temperature conditions. Switching in electromechanical models is carried out using a button, and adjustments are made using a lever. There is also a scale with the necessary parameters.

Adjustment in electromechanical models is carried out using a wheel

Complex - electronic devices that may or may not be programmable. Switching modes in such devices is carried out using buttons or via touch screens.

Below we will dwell in a little more detail on the polar opposite types of regulators: mechanical and electronic.

Mechanical thermostats

Such devices are used much less frequently than electronic ones. They will not be connected to the mains, and the temperature is controlled by heating or cooling a special membrane.

Externally, a mechanical regulator is a small plastic box with a lever for adjusting the temperature. The device is equipped with a scale with divisions in the form of marks.

Inside the device there is an element responsive to temperature changes. On average, such an element allows an error of no more than half a degree. Temperature limits are usually within 5-30 ºC. The operating principle of the device is mechanical, so no power supply is needed.

Electronic thermostats

One of the distinctive external features electronic regulators - a display that displays the processes occurring in the heating system. Such devices are much more accurate than mechanical ones. The most expensive are programmable models, in which it is possible to set time parameters for heating operation, and the device can be programmed with an accuracy of the minute for a week in advance. Thermostats can be integrated into Smart Home systems.

An electronic thermostat is much more accurate than a mechanical one

There are regulators with infrared sensors. The principle of their operation is based on the perception of electromagnetic waves emanating from heated objects. The information received by the device is analyzed and on this basis the device “makes a decision” - turn off the heating or turn it on again.

Intelligent systems are capable of self-control. For example, if the sensor breaks heating system automatically switches to operating at a third of its power. This, on the one hand, does not allow the air in the room to cool too much, and on the other hand, it avoids overheating of the air.

Most thermostats are versatile. For example, instead of an IR heater, you can connect a heated floor system, which only requires reconfiguring the temperature sensors.

Note! Thermostats should not be placed in direct sunlight, in drafts or in external wall building.

Features of connecting a thermostat to an IR heater

The power of an IR ceiling heater for a city apartment should not exceed 3 kilowatts. The regulator you purchase must match the power of the heater.

height up to 1.5 meters;
location - wall;
Insulation is placed under the thermostat (this is necessary to avoid false alarms of the sensor on a cold wall);
only one regulator is used for one room;
To ensure safety, the device must not be covered with interior items (for example, curtains).

Connection diagram of the thermostat to the IR heater

Installation diagrams

The infrared heater is connected according to the same standards as other electrical appliances - using an outlet or a dedicated line from a separate circuit breaker on the electrical panel. Thus, neutral and phase wires are used.

The regulator is installed between the machine and the heating equipment. The thermostat is mounted in the network between the machine and the heating device.

Simple scheme

The thermostat has 4 terminals: two at the input (neutral and phase) and two at the output (plus and minus).

If one heater is installed:

two wires are routed from the electrical panel to the thermostat terminals;
two wires are connected to the output terminals in accordance with the polarity - they are connected to the infrared heating equipment (series connection).

If a pair of heaters is installed:

4 wires are removed from the thermostat (two each for neutral and phase) and directed to the IR heaters (parallel connection);
2 wires are led from the regulator to one, and then to the second heater (series connection).

Sometimes it may be necessary to connect the phase from the machine to the heating device (directly), and connect the neutrals through the machine. The downside of this option is the possibility of the thermostat not functioning properly.

Complicated scheme

A slightly more complex scheme for several heating devices provides the following:

the thermostat is connected to the machine on the electrical panel;
the output terminals are connected to a magnetic starter;
The starter contacts at the output are connected to the heating equipment.

The described connection option is ideal for powerful industrial systems or several infrared heaters. The magnetic starter here operates in automatic mode.

Particularly noteworthy is the need to pay attention to security issues. In particular, we are talking about grounding. The grounding loop of heating equipment must have conductors of the required thickness and low resistance. The security system must guarantee the removal of electricity, since the life and health of the residents of the house directly depends on this.

Connecting a thermostat is not an easy task. Special knowledge, skills and tools are required. Even if you installed the thermostat yourself, it is recommended to call a professional who can competently check the work done.

Features of connecting a thermostat to an infrared heater

If you have an infrared heater at home, then a thermostat is a must. The thermostat for an infrared heater is capable of controlling and maintaining set temperature values for a long time. In addition, it will allow you to warm up the rooms in advance, reduce the risk of fire and make the atmosphere in your home as comfortable as possible. To understand the intricacies of connecting a thermostat to an infrared heater, we will first look at the principle of its operation, the mechanism of operation and highlight the main types of thermostats.

How it works

Typically, the thermostat operates cyclically. In this case, the electrical network opens and closes. At this time, the temperature sensor sends signals and thereby regulates the temperature.

If the temperature rises, the resistance of the internal sensor decreases. If the resistance rises again, the desired temperature is reached, the thermostat starts and the electrical circuit opens. When the temperature drops and the sensor cools down, the reverse process occurs: the resistance increases, the thermostat turns on again, but this time the circuit shorts. Next, the thermostat is connected directly to the infrared heater and the room temperature is set automatically .

The thermostat controls the climate in the room and the main heat source. It turns itself on and off when necessary.

As you know, infrared micathermic heaters do not heat the surrounding space, but the objects in it. The thermostat does the same this process more convenient and thoughtful.

Types of thermostats

Almost all thermostats operate according to the cyclic principle described above. At the same time, there are many differences between them, which affect the connection algorithm, control mode and configuration:

Mechanical thermostats

They are not used so often, but they are reliable and easy to operate. Essentially, a mechanical thermostat is a small plastic box. having a lever to control the temperature regime. For ease of use, such a thermostat has a special scale with divisions (standard step is 1 degree).

A mechanical thermostat is not entirely suitable for a modern IR heater, but connecting it is not difficult at all.

The fact is that the connection in this case does not require power supply. the process is completely mechanized. Climate control occurs through heating or cooling of the membrane inside the thermostat structure. As a rule, in addition to the temperature switch lever, there is a button and a power indicator light on the thermostat body.

Why is mechanics popular? The connection diagram of a thermostat with a mechanical principle is easy to understand even for a beginner, and its simple design ensures long service life. In addition, such a device costs much less than its electronic counterparts.

Electronic thermostats

One of the main features of these devices is availability of display. on which all necessary information about the settings and processes occurring in the heater and the surrounding area. They require a mandatory connection to the electrical network. Such models are more expensive than mechanical ones. The control panel can be either push-button or touch-sensitive. Some programmable models allow you to set parameters such as heating for the day or week.

Such devices can also be controlled remotely, for example, using mobile applications.

In addition, to such a thermostat you can connect not only an infrared heater, but also a heated floor system. To do this, you only need to slightly change the temperature settings.

A micathermic heater equipped with an electronic thermostat should not be installed under the UV rays of the sun or in a draft area, then it will last much longer and avoid breakdowns.

Thermostat connection options

Now you need to figure out how to connect the thermostat to an infrared heater if you do not have any experience in such work:

A micathermic heater for a home should not have a power of more than 3 kW.
It is not recommended to install the thermostat directly next to the device.
Avoid getting hit sun rays to the thermostat housing.
It is not advisable to connect an infrared heater to a thermostat in rooms with high humidity.

Connection diagram of the thermostat to the IR heater

Let's consider standard scheme connecting a household infrared heater via a thermostat:

As a rule, a micathermic heater is connected to a standard outlet or using a dedicated line from a machine on the electrical panel. The thermostat is built into the network between the heater and the machine.
Pay attention to the design of the thermostat. It has four terminals: two at the input and, accordingly, the same number at the output.
If one heater is connected, then two wires extend from the electrical panel to the terminals of the device. Two wires are connected to the terminals located at the output (positive and negative). It is important to consider polarity. The terminals are connected directly to the micathermic heater.
If two heaters are installed, then a pair of wires are again connected from the machine to the regulator: neutral and phase, and the wiring from the regulator is already made to a pair of heaters. The connection type is parallel.

Sometimes infrared heaters with a thermostat require more complex connection. To perform each step correctly, it is better to follow the recommendations of the video, where everything is clearly shown and supplemented with comments. It all depends on the design of the thermostat and the IR heater itself:

The thermostat is connected to the machine on the electrical panel.
The output terminals (+ and -) are connected to the magnetic starter.
The contacts of the starter are connected directly to the infrared heating device.

Connecting two heaters to a thermostat

It is worth noting that this algorithm is also suitable for the controller of industrial heating devices.

Infrared heaters with a thermostat require compliance with safety rules. When working with a thermostat, you must remember about grounding. Ground loop of your climate control device must have conductors of a certain thickness and with low resistance.

It is best to place thermostats on the wall. One regulator is enough for one room. It is not advisable to cover the device with anything: fabric, curtains, interior items.

Conclusion

Why are infrared heaters with a thermostat so good? They greatly facilitate the process of controlling the climate in the room, save energy and preheat the room even if you are far from home. There are a lot of advantages, the only difficulty is to correctly connect the thermostat to the heating equipment. Therefore, it is important to follow the instructions in the manual step by step and observe safety precautions.

NVT, I understand that you are having difficulty inserting this thermostat into a break in the heater’s power supply circuit, in a word - into a break in the cable. I think this is what you need to do:
1. the first cable core from the socket side - to terminal 6, from it - to one of the heater terminals;
2. the second cable core from the socket side - to terminal 1;
3. the second cable core from the heater side - to terminal 3;
4. Connect terminals 3 and 5 to each other
5. everything.))

I bought myself an infrared heater for my country house. After some time, I bought this BALLU BMT-1 thermostat. It does its job and is not expensive.

For a pro, I think installing such a thing is a matter of minutes, but I didn’t figure it out right away. And a friend who bought one also didn’t understand how to install it. I set it up and sketched out the diagram “on my fingers.” And, of course, it is better to use a 4-wire cable right away.

Why the hell would you throw another bare wire in the presence of a three-core normal num cable? in houses must be double-shelled.

How to connect a thermostat to an infrared heater?

With the onset of cold weather, many begin to think about additional heating of their homes. Since with the beginning of the heating season, as a rule, repair work begins at the sites of heating main breaks. Or thoughts arise to switch to electric heating as an additional alternative for a country house. In this article we will talk about a temperature-controlling device - a thermostat, and we will talk about how to install and connect a thermostat to an infrared heater.

Installation nuances

We will not go into the types and types of regulators, or arrange comparisons and tournaments. All of them are good in their own way and will fulfill their purpose, serving faithfully. The first thing you want to pay attention to is the installation location. It doesn’t depend on what type of heaters you have: infrared, panel, or heated floors. convection

Installation of a thermostat with an air temperature sensor is prohibited in the following places:

in close proximity to heaters;
in places where there is a draft;
in the heating zone of infrared emitters.

If you install the thermostat in the heating zone of the IR heater, its body will heat up earlier and distort the sensor readings. In places where there is a draft, the sensor will not show the desired temperature and the heaters will overheat the room, consuming excess electricity. The height of the temperature sensor should be placed in the comfort zone, at a level of 1.5 meters from the floor.

Connection diagrams

Rising prices for electricity supplies are forcing many to save different ways. This is especially necessary in the cold season, when various air heaters are used as an additional source of heat. To maintain comfortable indoor conditions, it is best to use a thermostat.

How to choose a suitable thermostat

Thermal sensors allow you to control household electric heaters and maintain the required indoor microclimate. These devices are divided into two main types.

Types of thermostats:

Mechanical;
Programmable.

Currently, the simplest models, and the most frequently used, are mechanical devices. It is worth noting that while they are similar in principle of operation and design, these thermostats may differ in the quality of the materials used for their manufacture.

Mechanical thermostats are used for wall installation. At the same time, they may differ in the type of installation (mortise and overhead models). It follows that these thermostats can be connected to any type of electrical wiring.

Operating temperature range for mechanical thermostats, varies from +5 to + 30 0 C. The control elements in these devices are a mechanical regulator, through which the required air temperature level is set, and a button for turning the thermostat on and off.

Note! The dimensions of mechanical regulators do not exceed the dimensions of sockets or switches, which allows them to fit perfectly into the interior.

The most advanced type of temperature controllers are programmable models. An extended temperature control range allows you to expand the possibilities of using this device.

Programmable models are able to monitor both the room temperature and the temperature heating device, which additionally provides fire protection.

Connecting a thermostat to an infrared heater

For high-quality and long-term operation of various electrical devices, it is necessary not only to select them correctly, but also to make the correct connection.

Connection features:

Do not install the regulator close to the heater;
Installation in a drafty room is not permitted;

First of all, when implementing electrical installation work, you need to read the instructions, which describe in detail which conductors are best to use for connections and circuits.

Note! In most cases, to connect thermostats, a PVA cable with 2.5 mm 2 cores is used.

It is worth noting that it is best to connect a device for heating indoor air and a thermostat using a separate cable, which is powered directly in the distribution panel.

The connection diagram is as follows. The phase and neutral conductors of the supply cable are connected to terminals marked (L - phase, N - zero). The wire coming from the thermostat to the device is connected to the terminals marked (L - 1 and N - 1).

When connecting the heater, it is important to correctly connect the grounding conductor, which is connected directly to the heater. The PUE rules state that breaking the grounding circuit is unacceptable. Therefore, the grounding wires of the device and the power cable are connected with a special terminal block.

Thermostat Ballu BMT 1: how to connect

The most common and well-known to many is a thermostat with an air temperature sensor Ballu BMT 1. It has proven itself in operation.

Sequence of work:

Installation and connection of the device.

First of all, you need to choose a place to install the heater. After this, you can start laying the wires. To provide fire safety, you should choose a wire with a cross-section of at least 2.5 mm 2.

Note! This thermostat is suitable for connection to open and hidden wiring.

Having laid the cables, we install the thermostat. Next, we connect the device. To do this, you need to understand the circuit, since many people are completely unclear how to connect the device correctly.

From left to right, the regulator terminals are labeled (3, 4, 1, 5, 6). We connect the supply phase wire to the terminal numbered (1). The neutral wires are connected using the terminal numbered (6). The working zero and the device zero are connected to one terminal.

After this, from the terminal numbered (3), you need to make a jumper to terminal (5). With this jumper, the device indication is connected. The phase wire leading to the heating device is connected to terminal (4).

In order not to get confused when connecting, you need to know the color marking of the wires. Phase wire (white or brown), neutral (blue), ground (yellow - green). It is worth noting that this scheme suitable for connecting the F2000 thermostat.

Mechanical thermostat TDC 1: operating instructions

This device is designed to control the operation of electrical heating equipment. The regulator is used for commercial and domestic use.

Rules of use:

Correct installation;
Exploitation;
Service.

The device is intended for wall mounting. The recommended installation height is at least 1.5 meters from the floor surface. To correctly regulate the air temperature in the room, it is not recommended to install the device in close proximity to doors and windows.

Installation of the device must only be carried out by a qualified electrician. This will allow you to connect the regulator correctly, which will not lead to failure of expensive electrical equipment.

Note! Install and connect the regulator in compliance with safety regulations.

Maintenance of the regulator must be performed only when there is no voltage in the electrical network. It is worth noting that the quality of connections between conductors and terminals is carried out at least once a year.

It is important to understand that before installing the device, it is necessary to inspect the thermostat for chips or cracks on the device body. It is recommended to use the regulator only with working equipment.
