What is a thermostat and what is it for?
A thermostat is a device with which you can set the desired temperature in the 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 support comfortable temperature automatically.

How is the Ballu BMT-1 thermostat disassembled?
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 scheme.

Where and how is the Ballu BMT-1 thermostat installed?
The Ballu BMT-1 temperature controller 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. You need to install the thermostat in a place where there are no drafts and direct sunlight. This is necessary for the correct operation of the temperature sensor installed in the thermostat.

How to connect the heater to the thermostat?
To connect the thermostat, minimal knowledge in electrics is required. The Ballu thermostat is connected according to the diagram that goes in the instructions to the heater or to the thermostat.

How many heaters can be connected to the Ballu BMT-1 thermostat?
The Ballu BMT-1 thermostat has a maximum allowable current of 16 A. This means that it can withstand a total power connected to the thermostat, 3500 watts. For example, you have 3 heaters of 1000 W in your 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 temperature in the room is significantly lower than the temperature set after the heaters have been operating for a long time, this may mean that you do not have enough power from the installed heaters. It is required to change the heater to a more powerful one or add another heater.
Another reason for this temperature discrepancy may be that the thermostat is exposed to direct sunlight or streams. warm air. The temperature inside the thermostat is higher than the air temperature in the room, which leads to incorrect operation.
If the room temperature is higher than the set temperature, then the cause may be drafts in the area where the thermostat is installed, or a cold, freezing wall on which it is installed.
Also, do not install the thermostat at an angle to the left or right. Ventilation holes must be strictly below and above and must not be closed by anything. Otherwise, errors may occur. set temperature both large and small side.

I want to put heaters on the balcony and regulate 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 you want to control the temperature.

There is no “on / off” button in the Ballu BMT-1 thermostat, what if I want to turn off the heater completely?
In this case, there are several options. One of them is to make a plug on the end of the wire and turn the heater on or off from the outlet. You can also put a separate switch next to the thermostat or make a connection from a separate machine 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.
Electronic has a built-in thermometer, which allows you to measure the temperature in the room. There is no thermometer in the mechanical thermostat. It only has a regulator that turns the heater on and off depending on the set temperature. Therefore, if you need an accurate temperature measurement, then it is better to use an electronic temperature controller.
A mechanical thermostat is more resistant to voltage drops. 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 be either too cold or too hot.

If I have a 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). A magnetic starter is selected based on the power of all the heaters that you want to connect.

What is a magnetic starter and how is it connected?
An electromagnetic starter is called 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 scheme that goes in the instructions for the heater.

Does the thermostat make any sounds during operation?
When the set temperature is reached, the Ballu BMT-1 thermostat makes 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 a heat generating device, reducing the consumption of expensive electricity to the lowest possible level.

Moreover, such a regulator sets the level of heating of the room, providing the opportunity to obtain the most comfortable temperature. Therefore, no 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 nodes:

  • temperature sensor installed near a heat source and / or in a heated room.
  • control unit , which processes the signals of the temperature sensor.

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

  • The control unit receives the heater operation program, which indicates the temperature regime 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 turns on the heating element if 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, heating the room only to the desired temperature. In this case, the 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. For such regulators, a special plate or diaphragm made of a material sensitive to temperature deformations is used as a temperature sensor. Therefore, the control unit for the thermo mechanical regulators, in fact, no. The plate closes or opens the contacts of the electrical circuit that feeds the infrared heater, under the "influence" of the actual temperature in the house. And all the regulation consists in fixing the set temperature with the help of a mechanical lever, with 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.

Scheme of connecting an infrared heater to a thermostat

Electronic devices. The temperature sensor of such a device captures 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 the embedded algorithm (program). Electronic instruments have only digital controls. The signal processing algorithm from the sensor is set using factory programs or buttons on the case. Information about the 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 autonomy of control. For example, infrared heaters with a thermostat for summer cottages can be programmed for a week of work on the air temperature outside the house and not even go out of town to control and adjust the operation of the heating system. Mechanical regulators cannot do this - the user will have to “turn the wheel” of the settings almost daily.
  • Main disadvantage – work only in the presence of voltage in the network.

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

  • A separate regulator is installed in each heated room.
  • A heat-reflecting screen must be installed between the temperature sensor and the supporting surface.
  • Ceiling infrared 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 shield to the regulator, which ends at the incoming “zero” and “phase” terminals.
  • A power supply line is pulled from the regulator to the heater, starting from the outgoing terminals of "zero" and "phase".
  • External temperature sensors are connected to the corresponding connectors of the temperature controller, connected to the controller using separate lines or wireless communication protocols.

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

Thermoregulators for infrared heaters are necessary to control and automatically maintain the set temperature in the room. Without this device it is difficult to imagine efficient work modern heating equipment.

The thermostat controls and maintains the set temperature in the room

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. Further, the sensor gradually cools down, its resistance increases, which again leads to the operation of the thermostat and the circuit is closed, i.e. connecting an IR heater. This principle of activity applies to all types of thermostats, regardless of their filling.

Types of thermostats

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

Also, regulators differ in the temperature regime of activity. There are such types of thermostats:

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

In terms of design, there are two types of regulators:

  1. Simple - mechanical and electromechanical models, which are characterized by low cost and limited possibilities for precise control over temperature regime. Switching in electromechanical models is carried out using a button, and adjustment is carried out with 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 by buttons or through touch screens.
  • Below, we will dwell in more detail on the polar opposite types of regulators: mechanical and electronic.

    Mechanical thermostats

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

    Externally, the 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 scratches.

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

    Electronic thermostats

    One of the distinguishing 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 the time parameters for the operation of heating, and the device can be programmed to the nearest 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 work is based on the perception of electromagnetic waves coming from heated objects. The information received by the device is analyzed and on this basis the device “makes a decision” whether to 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 work at a third of its capacity. This, on the one hand, does not allow excessive cooling of the air in the room, and on the other hand, it helps to avoid overheating of the air.

    Most thermostats are versatile. For example, instead of an IR heater, you can connect a system of underfloor heating, for which you only need to reconfigure the temperature sensors.

    Note! Thermostats must not be placed in direct sunlight, in drafts or outer wall building.

    Features of connecting a thermostat to an IR heater

    The power of the ceiling infrared heater for a city apartment should not exceed 3 kilowatts. The purchased regulator must match the power of the heater.

    • height up to 1.5 meters;
    • location - wall;
    • a heater is placed under the thermostat (this is necessary to avoid false alarms of the sensor on a cold wall);
    • for one room, only one regulator is activated;
    • To ensure safety, the appliance must not be covered by interior items (e.g. curtains).


    Scheme of connecting the thermostat to the IR heater

    Mounting 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 machine 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 heater.

    simple circuit

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

    If a pair of heaters is installed:

    • 4 wires are removed from the thermostat (two for neutral and phase) and sent to 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 heater (directly), and connect the neutrals through the machine. The disadvantage of this option is the possibility of improper functioning of the thermostat.

    Complicated scheme

    A slightly more complicated scheme for several heating appliances provides for the following:

    • the thermostat is connected to the machine on the electrical panel;
    • terminals at the output are connected with a magnetic starter;
    • the contacts of the starter 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 works in automatic mode.

    Of particular note is the need to pay attention to security issues. In particular, we are talking about grounding. The ground loop of the heating equipment must have conductors of the required thickness and low resistance. The security system must guarantee the diversion of electricity, since the life and health of the residents of the house directly depend on it.

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

    Features of connecting the thermostat to infrared heater

    If you have an infrared heater at home, then a thermostat is a must for it. The thermostat for an infrared heater is able to control and maintain the 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 first consider the principle of its operation, the mechanism of operation and highlight the main types of thermostats.

    How it works

    Normally, the thermostat works cyclically. when this occurs, the opening and closing of the electrical network. At this time, the temperature sensor sends signals and thus controls 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 circuit opens. When the temperature drops and the sensor cools down, the reverse process occurs: the resistance rises, the thermostat turns on again, but this time there is a circuit closure. Next, the thermostat is connected directly to the infrared heater and the temperature in the room is set automatically .

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

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

    Types of thermostats

    According to the cyclical principle described above, almost all thermostats function. 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 distinguished by reliability and ease of operation. In fact, a mechanical thermostat is a small plastic box. with a lever for temperature control. For ease of use, such a thermostat has a special scale with divisions (the standard step is 1 degree).

    A mechanical thermostat is not quite suitable for a modern IR heater, but its connection is not difficult at all.


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

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

    Electronic thermostats

    One of the main features of these devices is the presence of a display. which contains all the necessary information about the settings and processes occurring in the heater and the surrounding space. They require an electrical connection. Such models are more expensive than mechanical ones. The control panel can be both push-button and touch. In some programmable models, you can set parameters such as heating for a day or a week.

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


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

    A mikathermal heater equipped with an electronic thermostat should not be installed under the UV rays of the sun or in a draft zone, 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:

    1. Micathermal heater for the home should not be more than 3 kW.
    2. The thermostat is not recommended to be installed directly next to the device.
    3. Avoid direct sunlight on the thermostat housing.
    4. It is undesirable to connect an infrared heater to a thermostat in rooms with high humidity.


    Scheme of connecting a thermostat to an IR heater

    Consider standard scheme connecting a household infrared heater through a thermostat:

    1. As a rule, a mikathermic heater is connected to a standard socket or using a dedicated line from the machine on the electrical panel. The thermostat is built into the network between the heater and the machine.
    2. Pay attention to the design of the thermostat. It has four terminals: two at the input and, accordingly, the same number at the output.
    3. If one heater is connected, then two wires go from the electrical panel to the terminals of the device. Two wires are connected to the terminals that are located at the output (positive and negative). In this case, it is important to consider polarity. The terminals are connected directly to the mikathermic heater.
    4. If two heaters are installed, then a pair of wires is again connected from the machine to the regulator: neutral and phase, and wiring is already being done from the regulator to a pair of heaters. The type of connection in this case is parallel.

    Sometimes infrared heaters with a thermostat require a more complex connection. To correctly complete each step, 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:

    1. The thermostat is connected to the machine on the electrical panel.
    2. The output terminals (+ and -) are connected to the magnetic starter.
    3. The starter contacts are connected directly to the infrared heater.


    Connecting two heaters to a thermostat

    It should be noted 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, remember about grounding. The ground loop of your climate control device must have conductors of a certain thickness and with little resistance.

    It is best to place the thermostats on the wall. One controller is enough for one room. It is undesirable to cover the device with something: cloth, curtains, interior items.


    Conclusion

    Why are infrared heaters with a thermostat so good? They greatly facilitate the process of climate control 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 cable break. I think this is how it should be:
    1. the first cable core from the side of the socket - to terminal 6, from it - to one of the heater terminals;
    2. the second cable core from the side of the socket - to terminal 1;
    3. the second core of the cable from the side of the heater - to terminal 3;
    4. connect terminals 3 and 5 to each other
    5. everything.))

    Bought for myself country house infrared heater. After some time, I bought this BALLU BMT-1 thermostat. 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 did not understand how to install it. Put and threw the scheme "on the fingers." And, of course, it is better to use a 4-wire cable right away.

    why the hell did you throw another bare wire in the presence of a three-core normal num cable? in houses should be in a double shell.

    How to connect a thermostat to an infrared heater?

    With the onset of cold weather, many begin to think about additional heating your dwelling. Since with the beginning of the heating season, as a rule, repair work begins at the sites of gusts of heating mains. Or there are thoughts 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, namely, we will talk about how the thermostat is installed and connected to an infrared heater.

    Installation nuances

    We will not go into the types and types of regulators, 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 does not depend on what type of heaters you have - infrared, panel, warm floor. convection.


    The 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, because when located near a heater, the air next to it will heat up to the desired temperature earlier, which will lead to false alarms, as a result of which the room will not heat up to a comfortable temperature.

    If you install a 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 placement of the temperature sensor in height should be done in the comfort zone, at a level of 1.5 meters from the floor.

    Wiring 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 gives a connection diagram for their products. In case of deviation from the requirements and savings on wire and thermostats, there is a high probability of equipment failure or a fire hazard.

    Scheme of connecting the thermostat to an infrared heater with a power of up to 3.5 kW:


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

    In the event that 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 how the temperature controller is installed. As you can see, there are some peculiarities in the installation and connection of the thermostat, so it is important to first read the instructions from the manufacturer, and then proceed to the main process.

    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 conditions in the room, it is best to use a thermostat.

    How to choose the right thermostat

    Temperature sensors allow you to control household electric heaters and maintain the necessary microclimate in the room. These devices are divided into two main types.

    Types of thermostats:

    • Mechanical;
    • Programmable.

    Currently, the simplest models, and the most commonly used, are mechanical devices. It is worth noting that, despite the similarity in principle of operation and device, these thermostats may differ in the quality of the materials used for their manufacture.

    Mechanical thermostats are used for wall mounting. 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.


    The operating temperature range for mechanical thermostats varies from +5 to + 30 0 C. The controls in these devices are a mechanical regulator, through which the required level of air temperature is set and a button to turn 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. Extended range of temperature adjustment, allows you to expand the possibilities of using this device.

    Programmable models are able to monitor both the air temperature in the room and the temperature of the heating device, which is additionally fire protection.

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

    Connection Features:

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

    First of all, when carrying out electrical work, you need to read the instructions, which describe in detail which conductors are best used for connection and circuit.

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

    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 switchboard.


    The connection diagram is as follows. The phase and neutral conductors of the supply cable are connected to the terminals marked (L - phase, N - zero). The wire going 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 ground conductor, which is connected directly to the heater. The rules of the PUE state that a break in the ground circuit is unacceptable. Therefore, the ground wires of the device and the power cable are connected with a special terminal block.

    Ballu BMT 1 thermostat: how to connect

    The most common and well-known to many is the temperature controller with the Ballu BMT 1 air temperature sensor. 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 that, you can start laying wires. To ensure 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 concealed wiring.

    After laying the cables, install the thermostat. Next, we connect the device. To do this, you need to understand the circuit, since many do not understand how to connect the device correctly.

    From left to right, the controller terminals are labeled (3, 4, 1, 5, 6). To the terminal numbered (1), we connect the supply phase wire. Connections of neutral wires are carried out by means of the terminal numbered (6). Working zero and zero of the device are connected to one terminal.


    After that, from the terminal numbered (3), it is necessary to make a jumper to the terminal (5). This jumper connects the device indication. To terminal (4), a phase wire is connected to the heating device.

    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.

    Using this information, you can easily not only select a thermostat and connect your electric heater to the mains, but also ensure the correct use and maintenance of the device.

    Unlike radiators, infrared heaters help to heat a larger area at a much lower temperature. This allows economical heating modern houses. Controls should be used to ensure thermal comfort for users and controlled operation of floor standing equipment. Below is information on how to connect the Ballu BMT 1 and BMT 2 thermostat, the features and benefits of these devices.

    Control via TDC thermostat

    Thermal comfort is a subjective feeling of each person. This is the condition under which people perform the usual homework without excessive overheating or hypothermia. Thermostats are needed to regulate the temperature, they help infrared heaters to function properly. TDC is a modern electronic feedback device that maintains an accurate set temperature.

    Its control system is very simple and at the same time effective - you should set the value that you want to achieve in the selected room. Sensors detect the temperature and then turn on the device to reach the desired value. The heaters then turn off automatically. The next switch on occurs when the temperature starts to drop. Such a control system saves energy - heaters operate only about 4-6 hours a day.

    Before answering the question, TDC 1 thermostat: how to connect, you should know that the temperature in the apartment largely depends on the location of the heater. It is recommended to install it in an accessible place, away from drafts (windows, doors).

    Key Benefits

    The main advantages of TDC thermostats include:

    • ease of use (just use the dial to set the desired temperature in the room);
    • low purchase and maintenance costs.

    Thus, controlling the temperature inside the house allows you to maintain sufficient thermal comfort and reduce heating costs.

    Before installation

    You should know that the answer to the question: thermostat TDC 2 - how to connect, is directly related to the installation of Ballu BMT 1. To install them safely, it is recommended to follow the precautions:

    • before starting work, turn off the heater from the mains;
    • use wires with standard colors and appropriate cross section.

    Meaning of wire colors:

    • brown phase - control cable;
    • blue phase - neutral wire N ("zero");
    • red or black - phase conductor.

    Installing a thermostat

    A few words about how to connect the Ballu TDC thermostat 1. The device must be installed in sequence:

    1. Move the thermostat cover aside and remove the screws and plugs.
