How to connect a room thermostat to a boiler. We study the room thermostat for the Baxi gas boiler

So that the microclimate does not depend on the weather, and the rooms have a stable temperature, you need to install a room thermostat for the gas boiler. What types of devices that regulate the operation of boiler equipment do manufacturers offer, how do such thermostats work and how do they communicate with gas heat generators? You will learn about everything by reading the article.

The practical use of a remote regulator - is it possible to do without it

Many private homeowners and people living in apartments with individual heating are familiar with the situation when they have to adjust the intensity of the boiler to constantly changing weather conditions. It is easier to maintain a heat-generating gas appliance in an apartment, at least in terms of the compactness of living quarters. The owners of private houses, who part-time have to be operators of boiler equipment, sometimes have to run short distances if the boiler house is not in the main building.

All modern gas units are equipped with automation that regulates the intensity of the gas burner or the frequency of its on / off. The automatic control system clearly responds to changes in the temperature of the circulating fluid, maintaining the thermal regime in a certain corridor set by the owner. But the temperature sensor that sends signals to the electronic "brains" is installed in the boiler's heat exchanger, so it cannot respond to weather changes. As a result, we have the following situation:

• it has become sharply cold outside, and the household is beginning to freeze slightly;
• there is a sudden thaw outside the window, and the windows are wide open, because in rooms with temperature pluses there is a clear bust.

It is useful to ventilate the premises intensively, but along with kilojoules, savings fly away through the window, which will have to be paid on bills for the consumed energy carrier. Shaking with unusual coolness is also good for the body, but still a constant comfortable air temperature is more pleasant and natural for housing that claims to be called modern.

To maintain the temperature regime within comfortable limits, it is not necessary to hire a stoker or run to the boiler every hour. It is enough to install a thermostat for the boiler, which would read information about the actual temperature within the living space and transfer the data to the control system that regulates the operational activity of the heating equipment. Such a move will allow you to "kill several birds with one stone":

• maintaining a constant comfortable temperature within the housing;
• significant energy savings (gas);
• reduced load on the boiler and circulation pump (they work optimally, without overloads), which prolongs their service life.

And these are not miracles, but the result of the work of a room temperature sensor - an inexpensive, but very useful device, which in European houses and apartments (and they know how to save on a "communal apartment") is an indispensable addition to heating equipment. Even the most expensive remote thermostat with a liquid crystal touch display and many functionalities easily pays for itself during the heating season.

How a room thermostat works - a simple system

The remote thermostat is a compact device that contains a temperature sensor integrated with a system of contacts that open / close when the temperature changes. On the outside of the device there are devices for controlling the operation of the device. This can be a rotary knob with graduation (in the simplest models), a keypad or an LCD display that responds to touch (touch).

Using the thermostat control system, the homeowner sets the desired temperature regime, which is maintained automatically, regardless of the weather situation outside the window. The temperature corridor for various devices is from 0.3 to 1.0 degrees. This means that if the mode is set to 20 degrees, then the temperature fluctuations will be approximately in the range of 19.7-20.7 degrees.. Such changes in temperature regimes are not noticeable to our body, so the temperature in the rooms can be considered stable. A remote thermostat for a gas boiler is installed in one of the living rooms with the most constant temperature on the wall.

How does the “brains” of the boiler, which regulate the intensity of heat production, learn about the mode in which the gas burner should operate? For this, the regulator is interconnected with the boiler controller. It is carried out by wire using electrical signals or by means of the ether (radio signal). When the temperature in the control room (where the temperature sensor is installed) drops to the lower limit (according to the set mode and temperature corridor), the burner turns on and increases the degrees of the coolant in the heating circuit. When the upper temperature threshold is reached, the room thermostat sends a signal to turn off the gas supply to the burner.

This is how it is easy to understand how the temperature regime is analyzed by the sensor in the living room, the signal is transmitted to the boiler control system and the gas boiler burner is turned off / on if necessary. Often, a circulation pump is integrated into the operation of the remote temperature sensor / boiler complex, which works only if it is necessary to "drive" a portion of the heated coolant. All this makes the heating system as economical as possible, increases the durability of the equipment and provides thermal comfort within the living space.

Types of thermostatic devices - which one to choose

Remote temperature controllers, despite their simplicity and compactness, have several varieties, so that the consumer will have something to choose from. Manufacturers endow the devices they have developed and manufactured with sensors of various sensitivities, which affects the size of the temperature gap. But these differences are of least interest to consumers, in the top of their attention are the following device parameters:

• method of interconnection between the thermostat and the boiler (wired or wireless);
• functionality of the temperature control device (basic and additional features, ease of control of the device);
• device cost.

The method of connecting the thermostat to the heat generator control unit using a cable is less convenient, but more reliable. The downside is that you need to figure out how to hide the wires. Ideally, if a complex repair is carried out along with additional devices that optimize its operation. In such a situation, it will not be difficult to hide the wiring (in a strobe or at), including the cable connecting the room regulator to the boiler control unit. Plus - in a more reliable contact of the interacting devices and the power supply received by the temperature controller through the same wires.

Remote temperature sensors with wireless communication with a heat generator are convenient for their portability (they are not tied to a cable, so the installation location can be easily changed if desired). Minus - in the possible presence of interference in the path of radio waves and powered by batteries that need to be changed periodically. So that the consumer does not forget to replace current sources in time, such devices are endowed with the ability to give sound signals when the battery life is coming to an end.

The main task of a room thermostat is to maintain a stable temperature regime in a given corridor. The simplest devices are only capable of this. They are simple in appearance - a plastic case and a rotary thermostat knob. More advanced models make it possible to program the temperature regime for a day or even a week. They are equipped with a functional button or touch external control and look much more presentable. The cost of room thermostats directly depends on the functional complexity of the model and a little on the brand name.

The most inexpensive will be some simple device compatible with all models of boilers, made in the countries of Southeast Asia. Much more will have to be paid for a multifunctional model of an advanced European brand that is compatible with their own boilers. Although there are many universal models of thermostats on the market, experts recommend choosing devices from the same manufacturers that produced the boiler you installed. In such a combination, the boiler control unit and the remote thermostat will interact as efficiently as possible.

Installation and connection - do it yourself or hire a master

Now manufacturers of gas boilers offer consumers equipment in three configurations:

• minimum, when it is possible to connect an interaction unit with a remote temperature sensor to the heat generator;
• intermediate, which provides for a built-in block for connecting a room thermostat;
• full, if the unit is installed, and the thermostat is included in the kit.

The first option allows the consumer to purchase a gas boiler at an affordable cost and complete the equipment during operation. A complete set is rare, only in cases where the boiler control unit is designed to "cooperate" only with temperature sensors produced by the same manufacturer. The second option is most common, when the connection unit is mounted, but the manufacturer allows the consumer to choose the model of the remote temperature controller that he likes.

To connect a temperature-regulating device, if it comes with the boiler, you can do without the help of a specialist. It is enough to install the heating equipment and connect it (including to the power supply), after which, according to the recommendations in the operating instructions, deal with the thermostat.

It will not be difficult with the built-in adaptive block. The purchased device should also have detailed instructions with the rules for connecting and configuring. If the instruction did not help, or for some reason it does not exist, you will always find the necessary information on the worldwide web. A specialist will be needed only in case of minimal equipment or a desire to equip an old-style gas boiler with a remote thermostat. First you will need to purchase all the necessary components, after which the master will install them and prepare them for work.

At the end, a few words about the rules for installing the thermostat itself. It is advisable to mount the device in spacious rooms with good air exchange (entrance hall, living room, hall), but not in the kitchen or bathroom. The thermostat is installed at about half the distance between the floor and the ceiling (1.25 m with a wall height of 2.50). The thermostat should not be placed near or other sources of kilojoules, blocked by bulky furniture. Avoid exposing the device to direct sunlight.

Installation and connection of the thermostat

Modern manufacturers of boilers and various heating systems complete their products with wireless ports or connectors for additional connection of temperature sensors.

There are two fundamental options for connecting a temperature sensor:

• through the cable of the regulator;
• using the terminal located on the heating equipment itself.

You can easily find out how to connect the thermostat to the boiler from the instruction manual that came with the device by finding the appropriate section with a detailed description of the installation diagram.

There are some general rules of thumb and requirements on how to install a temperature controller regardless of its functionality. It should be clearly remembered that the correct operation of the entire heating system directly depends on the cooling and / or heating of the thermoelement itself.

The speed of its response is directly dependent on the rate of temperature changes. Therefore, it becomes obvious that if the temperature sensor is blocked by any objects, then it will react with a delay to changes in the temperature parameters in the room, and its indicators will become unreliable.

As practice shows, the thermostat should be installed:

• away from any electrical appliances to minimize the effect on the sensor of the heat fluxes emanating from them;
• ensure free air access to the device itself
• avoid unwanted closing of the thermostat heavy curtains or pieces of furniture;
• in the coolest places, especially in those where people spend most of their time;
• in places where no direct sunlight;
• at the points inaccessible to drafts;
• at a height of one and a half meters from the floor, since cold air is always concentrated at the bottom, and warm air invariably rises up the room, this rule is especially true if underfloor heating is installed.

Adjustments

After it was possible to connect the thermostat to the heating boiler, it is necessary to carry out the appropriate settings for the installed equipment. Each product comes with an instruction manual that details the set-up plan and steps that must be followed carefully.

This is the only way to organize the correct setting of the thermostat, thereby creating a comfortable and favorable temperature regime in the room. On the outer panels of most devices, there are various relays and buttons with which you can make the appropriate adjustments.

The thermostat for an electric boiler, as a rule, can support two fundamental modes: economical and optimal. The first lowers the air temperature to a level that is most favorable for a calm and comfortable sleep, and the second maintains a favorable temperature regime during the day.

You can practically adjust the temperature sensor of a solid fuel boiler if you consistently follow the following recommendations:

After the initial adjustments, experts advise checking the operation of the equipment in various temperature conditions, up to the maximum.

Benefits of Using a Temperature Controller

Proper installation and adjustment of the heating boiler thermostat provides many advantages.

Among them, the main ones are:

Functionality and device selection

Modern manufacturers offer a huge selection of thermostats for various heating boilers. All of them differ in the degree of their functionality and a set of certain options, so it can be difficult for a simple layman to make the right choice. Next, some of the most popular models of thermostats for heating boilers will be considered.

Baxi (Baxi)

This manufacturer, in addition to its main activity - the manufacture of heating equipment, is also engaged in the production of additional accessories for it. Among the many manufactured devices, Baxi thermostats (Baksi) deserve special attention.

They allow you to maintain the desired temperature and provide a round-the-clock comfortable climate. If such a thermostat is installed in tandem with one more accessory - an outdoor temperature sensor, then the operation of the boiler will become much more efficient due to the difference between the outdoor and indoor temperature microclimate.

Immergas

A well-known Italian company produces room programmers that provide an economical mode of operation of heating equipment. They can be controlled both manually and remotely. Immergaz thermostats are also called weekly thermostats, as it allows you to set different temperature conditions both on weekends and on working days.

The principle of operation is based on the supply temperature of the coolant itself circulating in the heating system, and is set on the control display. At the same time, the boiler itself maintains the required temperature by turning the burner on or off by simulating power in the required ranges. Thermostats of this brand allow you to turn off the heating mode of the heating batteries even when it rises by half a degree from the set temperature.

Vailant (Vailant)

This temperature controller is designed to automatically provide room temperature within the range of up to 35 0 C. A weekly programming option is available.

At the same time, the Vailant temperature sensor itself (Vailant) can be located in any part of the room, even in the basement, but this does not adversely affect the functionality of the equipment itself.

Proterm

The range of room temperature sensors from this manufacturer includes both easy-to-maintain equipment and more complex programmers. The installation of one or another Proterm regulator completely depends on the technical capabilities of the boiler itself, more powerful equipment can produce temperatures up to +35 0 C. Any category of products from this company guarantees smooth and uninterrupted operation of any heating equipment.

Ariston

Despite the rich assortment presented on the market of heating appliances, thermostats of the famous Italian brand Ariston, used to equip any type of boilers, have been in constant demand for many decades.

Such sensors can be programmed for weekly, daily and even hourly operation, which not only provides effective savings, but also significantly extends the life of the equipment itself.

Bosch

These temperature sensors are suitable for both single-circuit and double-circuit boilers. They have an intuitive, simple control menu. There is an additional mode - "vacation" with the ability to specify the start and end dates of the absence of people in the room.

In addition to Bosch thermostats, as well as the above brands, temperature sensors such as Wisman, Ferolli, Evan and Zota controllers have similar functional features.

Many years of experience in the production and use of temperature controllers shows that the cost of purchasing it is easily compensated when the boiler is operated even at maximum mode for four or five years. This is a fairly convincing fact, providing a future prospect of financial savings, given the ever-increasing heating tariffs.

A thermostat is a temperature control device that controls control of the boiler operation depending on the air temperature.

Temperature controllers are indoor and outdoor(street). Outdoor sensors can also be used.

Baxi gas equipment has the ability to connect both indoor and outdoor thermostats and sensors.

Room appliances have a greater effect on timing(switching on and off) of the boiler, and the street ones allow the unit to regulate coolant temperature. The air temperature in the street and in the house is constantly changing, and the thermostat helps increase or decrease gas flow for space heating.

Types of thermostats for Baxi gas boilers

Devices for Baxi are thermostats compatible with Italian brand gas boilers.

In terms of their functions, they do not differ from systems for other gas equipment. Usually thermostats are distinguished by:

• installation site;
• principle of work;
• control method.

According to the place of installation, the devices are divided into indoor and outdoor. Rooms are used more often than outdoor or outdoor, as they do not require protection from difficult weather conditions.

Outdoor options are used in cases where the owner of the house seeks to make the operation of the equipment as accurate and economical as possible. The combination is especially effective in such cases. room thermostat and outdoor sensor, which is allowed by Baxi units.

According to the principle of operation, the thermostat can be mechanical or electronic. In the first case temperature must be set manually. In the second- a program is laid, according to which the boiler changes the intensity of work automatically.

The way to control a mechanical thermostat is to manually set the mode turning a knob or pressing a button. An electronic or programmable version can be operated remotely. In this case, the sensor is located in any part of the room, and the control takes place remote control, computer or phone. At the same time, contact with gas equipment remains wired.

How to choose a Baxi thermostat

Thermostats and sensors for gas boilers Baxi produced by the Italian company, so it is best to choose them. If this is not possible, you need to look for a thermostat that matches the parameters that are usually indicated in instrument data sheets. It is appropriate in such cases to take the advice of a specialist who is familiar with the Baxi brand.

Attention! Check carefully compatibility thermostat with a gas boiler for which it is purchased. Please note that devices one company interact best with each other.

When choosing a thermostat, it must be taken into account whether the boiler is used constantly or only from time to time. If the house has an inexpensive unit model that rarely works, then it is enough a simple regulator with a minimum of functions.

Conversely, if heating and hot water are needed all year round and an expensive model of the unit is used, it is better to install a programmable thermostat.

And if the cottage is involved smart home system, then the ability to control the device via the Internet will be very handy.

This feature has been implemented in most advanced models.

The calculation of the technical requirements for the thermostat is based on the requirements for the operation of the boiler. For example, if the owners leave for work in the morning and return only in the evening, thermostat with programmer, which will reduce the heating temperature and fuel consumption while no one is in the house.

And also, if the house is geographically located in a cold region, then it is better to purchase a thermostat with frost protection system: it automatically turns on the boiler if the air temperature drops up to +3°C. Such technical characteristics have, for example, room thermostat Baxi Magictime Plus.

Where to post

An important condition for the correct operation of thermostats is the accurate measurement of air temperature. Although all devices have an error up to several degrees, it can be minimized.

To do this, the room thermostat must be installed away from drafts and at a considerable distance from heating devices.

It is better to install the outdoor sensor so that it is not flooded with rain or covered with snow. These precautions are due to the fact that More accurate sensor readings, the more efficient the operation of the boiler and the lower the fuel consumption.

What materials are needed to connect

Connection materials are usually supplied with the thermostat. This is, first of all, the device itself, as well as mounting cable and fasteners. With their help, the device is connected to a gas boiler and fixed to the wall.

What tools are required for installation

To connect the thermostat, you may need:

• screwdriver;
• drill;
• side cutters;
• thermometer.

side cutters you can strip the ends of the thermostat wires, but as a rule they already have terminals that are screwed to the contacts of the gas boiler for a remote thermostat.

A drill is needed for holes in the wall into which dowels are installed. They are twisted screws on which the device is attached. Need for dowels does not apply if the wall is wooden.

A thermometer will be needed to check the air temperature after starting the thermostat.

Connection order

During the connection period, both devices should not work. To connect the thermostat and the gas boiler, it is necessary to study technical data sheets of both devices and follow the wiring diagrams and instructions. The ends of the cable for the temperature controller must be attached to the gas boiler contacts.

Then the cable must be stretched along the wall to the place where the thermostat is mounted. After that, at the selected point (usually it is located in the coldest residential area), the device is screwed to the wall. Finally, it is carried out setting up and checking the device.

How to check the operation of the device

To test the device, you must set the maximum temperature. Then you need to turn on the gas boiler and bring it to maximum efficiency mode(efficiency).

Upon reaching a comfortable temperature, it is necessary to accurately measure it next to the thermostat and set it as a threshold for switching off.

A device that regulates the operation of a gas boiler, focusing not on the temperature of the coolant in the boiler, but on the air temperature in the room - this is the temperature controller for the heating boiler. That is, this is an apparatus that provides not only control of the process of heating water with a gas boiler, but control of the process of heating it based on the final result.

Why buy a thermostat

When the operation of the gas boiler is adjusted manually, the equipment is forced to operate in a mode that involves constant short-term switching on and off. In this case, the start of water heating is performed for a short time - no more than 10 minutes. The constant circulation of water in the system is provided by pumping equipment, which operates regardless of the state of the heating elements.

Such an organization of the operation of the climate system is fraught with a significant consumption of electrical energy. In addition, this mode leads to rapid wear of all boiler systems. Therefore, it is not at all surprising that room thermostats have gained such popularity all over the world. In some Western countries, their installation is even considered mandatory. Since if the house is heated with a gas boiler, the presence of a “home controller” significantly reduces the cost of gas and electricity, and also helps to use expensive equipment more carefully.

The thermostat for the boiler has a certain response threshold (on average, about 0.2 ° C), when the air temperature drops or rises relative to the specified parameters, it either turns on or off the boiler and the pump. Such a system guarantees the owner of the thermostat a number of advantages:

• fully provides control over maintaining the required temperature in the home, which means that even on days of sharp temperature fluctuations outside the window, in a house where the thermostat works, coziness and comfort will always reign;
• with the advent of this equipment, the owners of a house or apartment immediately have at least one less problem: not only the “weather in the house”, but also the level of operation and health of the boiler will now be monitored by this small device;
• due to significant savings in fuel and electricity, the cost of purchasing the device pays off within a few months.

What are thermostats

Currently, the choice of thermostats is large, while they may vary depending on:

1. Type of boiler operation modes control:
   • wireless;
   • wired.
2. Functionality level:
   • simple;
   • provided with hydrostat function;
   • programmable.

The wireless room thermostat for a gas boiler is able to regulate the level of operation of the boiler and the heating of the air in the premises using a radio signal. For wired, only the method of connecting to the controller via wired connections is relevant.

The scope of possibilities of thermostats can be different. Less expensive - simple, reliable and durable wired thermostats do an excellent job with the list of basic functions, stably maintaining the level of set temperatures in the room (usually in the range of 10-30 ° C), but only in one mode. In addition, the operation of the device does not affect the level of fuel consumption by the boiler.

A completely different matter is a wireless programmable room thermostat for a gas boiler.

By purchasing such a device, you can use the features:

• remotely monitor and control the operation of the boiler;
• installation and configuration of various operating modes of heating equipment depending on the day of the week or time of day;
• control over fuel consumption and serviceability of gas heating boiler systems.

The list of possibilities for thermostats equipped with a gyrostat function is even wider. Such a room thermostat for a gas boiler is able to provide control not only over the temperature regime in the room, but also over the level of air humidity.

Connecting wireless option

The principle of operation of a room thermostat for a gas boiler is quite simple, but wireless thermostats remain the most convenient in terms of connection. Such a model, as a rule, consists of a couple of blocks:

• block for installation near a gas boiler (by connecting to a controller or gas valve);
• block with a set of control buttons and a display - designed for installation in a room from where it is planned to control the air temperature in a house or apartment.

Moreover, the connection of the thermostat to the boiler is carried out using the terminals, and the transfer of information from one unit to another is due to the use of a radio channel. Perhaps the only disadvantage of wireless models is their dependence on rechargeable batteries, which often need to be recharged or replaced. At the same time, the device itself informs the owner about the battery level, which, of course, is a plus.

Where to put the wires

The situation is much more serious when installing wired models. And although Experts recommend combining this procedure with repair work, since the wiring will most likely either have to be masked or laid in the body of the wall into the channel formed after it has been shredded.

Another disadvantage of wired thermostats is the need to allocate a separate room or a significant space in the house for placing the device. Since, according to the instructions, the correctness of their work may depend on the presence of sufficient free space.

It is also highly undesirable to install it near household, third-party climate control equipment and heating appliances, as well as in places where direct sunlight will fall on the device.

The process of connecting the thermostat, in principle, is not difficult. It is enough to follow the instructions drawn up by the manufacturer of the boiler and the thermostatic device.

About the mechanical thermostat

An important point, those who have chosen a more durable and reliable mechanical thermostat for their home, should remember that this device does not need to be connected to the mains and batteries. However, in the course of work on its connection, it will also not be possible to avoid fiddling with wires. But in this case, we are talking about wires that provide communication between the device and controlled climate technology.

The mechanical thermostat is connected to the boiler with a 2-wire connection.

The video shows how to connect the Ballu BMT-1 thermostat.

About the specifics of the setting

After you have successfully connected new equipment, you need to configure it, during which you can set the desired parameters, including the ability to:

• Heating, and in some cases, air conditioning in the room;
• Determination of the optimal delay period for the operation of the thermostat sensors (a window open for a short time or, conversely, the heat flow from the switched on hair dryer can “mislead” the device’s sensors, but turning on the response delay function will avoid errors;
• Setting the temperature fluctuation step. That is, choosing a step of 1 degree means that the thermostat will turn the boiler on or off when the air temperature changes by 1 o C.
• Determination of maximum comfortable temperatures. Some devices allow you to program the temperature regime depending on the time of day or day of the week (for example, on weekdays, when there is no one at home, you can lower the air temperature by several degrees, providing fuel savings, a couple of hours before the inhabitants of the house return, the device will turn on , will adjust the temperature until it rises to a comfortable level).

About compatibility issues

The method of connecting the thermostat to the boiler is largely determined by the choice of the thermostat model and can be performed both from the controller, from the battery, and from the network.

You can often meet the recommendations of boiler manufacturers when purchasing a simple or programmable thermostat for a gas boiler, focus on the boiler manufacturer and its recommendations. In principle, this advice is worth heeding, although, having looked through the pages of numerous forums where the issues of connecting climate equipment are discussed, one can often come across the opinion that, for the most part, products from different brands “get along” perfectly without conflict.

But the parameter that is really worth considering when deciding to buy a temperature sensor for a heating boiler in a regular climate or household appliance store or an online store is the area of ​​\u200b\u200bthe room heated by the boiler and the most preferred temperature regime.

TOP thermostats 2017–2018

Having studied the opinions of consumers and analyzed the information of several reputable online publications that annually compile rating lists of the most discussed models of climate equipment, it is easy to conclude that thermostats of such brands as are popular:

Bosch

At the same time, the company believes that the best thermostat for a Bosch gas boiler is, of course, Bosch. And, although there is so much information on the network about the successful symbiosis of the climate equipment of this manufacturer with thermostats from other companies. However, for example, the Bosch software digital thermostat definitely deserves attention. The model is equipped with a digital display, has a temperature sensor calibration, has backup power options. The appliance can adjust the room temperature according to the time of day and the days of the week.

The video details the Bosch EMS series regulators.

Ariston

Also, when choosing a room thermostat for an Ariston gas boiler, you should pay attention to the thermostats offered by this Italian company. Among them, you can also find models that can program the required temperature regime not only for the week ahead, but also for any hour of the upcoming week. There are also less complex, but cheaper options that “know how” to set the desired temperature regime for the next 24 hours. However, the availability of hourly programming helps homeowners solve a lot of problems, including saving gas and electricity.

We offer owners of Ariston boilers to take a closer look at the Sensys control panel.

Advantages:

• full system control via bridgenet® protocol;
• easy setup/management of system parameters;
• temperature control;
• display of parameters of the solar system (if connected);
• display of energy audit report (kW), solar system performance, reduction of CO2 emissions, hot water storage;
• electronic room temperature sensor;
• easy-to-manage daily and weekly programming of the heating mode;
• easy-to-manage daily and weekly programming of the DHW mode (in case of connecting an external boiler to a single-circuit boiler).

Protherm

This company also recommends connecting the thermostat to the Proterm gas boiler only when using "native" models. There are a number of reasons for this. For example, thanks to a special eBus switching bus, the temperature controller can control the modulation of a gas burner. Thermostats from other manufacturers cannot be connected in this way to the Proterm boiler. In addition, on the display of some models from Protherm, you can see not only the set operating modes of the boiler, but also the error codes that occur. In addition, the system, if necessary, is able to restart the boiler itself. In this way, the temperature of the boiler is regulated.

Buderus

Connecting a room thermostat to a Buderus gas boiler will also create fewer problems when it comes to a device manufactured by the same company. Moreover, the developers have provided a simple and intuitive interface for the device.

Programmable room thermostat Simple MMI 7 Days – with communication via OpenTherm™ protocol. Designed for complete boiler control and comfortable room temperature control

RQ

If you managed to purchase a room thermostat rq10, connecting to a boiler of the same brand is not difficult. Moreover, the quality of this technique rarely causes criticism.

Ferroli

Room thermostat for gas boiler Ferroli – very successful development of the Italian company.

Baxi

The thermostat for the Baxi gas boiler has also become a trend. It is easy to install and manage, also featuring an intuitive adjustment system and providing significant savings to home owners.

The BAXI mechanical room thermostat is used to determine the room temperature and transmit data to the boiler, providing feedback. Regulates room temperature from 8°С to 30°С

conclusions

The thermostats of listed companies successfully help to solve problems such as:

• the problem of clocking the gas boiler and pump (unreasonably frequent switching on and off of devices);
• setting the optimal thermal regime by day and hour;
• simplification of the maintenance process of the heating device;
• setting fine adjustments.

All these features will provide comfort in any home and a good mood for its inhabitants.

Achieving a comfortable temperature in the house, we manually control the operation of the gas boiler. This regulation is very relative, since we set the temperature of the coolant on the boiler. As soon as the weather conditions change in one direction or another, as the temperature in the rooms decreases or rises, it is necessary to regulate the heating of the coolant on the boiler again. This applies to all gas water heating installations, even expensive ones with a high level of automation. You can get rid of the daily running around to the boiler room if you install a remote thermostat for a gas boiler. Some manufacturers of boiler equipment supply it with their products as an option.

How it works?

In a standard situation, the boiler installation heats the water to the set temperature and does not react in any way to the fact that the house becomes hot or cold after a change in the weather. Even daily fluctuations in street temperature make themselves felt. The regulation of the gas boiler according to the heat carrier is indirect, in order for the regulation to be direct, it must be carried out according to the air temperature in the premises. For small one-story houses, it is enough to install one room thermostat in the passage room to solve the problem.

The simplest thermostat consists of a sensitive element, which is an actuator, and a contact group with a regulator. The thermoelement is a closed capsule (bellows), most often a mixture of gases is pumped into it, less often a liquid. The bottom line is that this placeholder is sensitive to changes in ambient temperature. When it rises, the gas mixture expands, stretches the bellows and moves the rod that closes the contacts. A decrease in temperature causes the reverse process and the contacts open.

The task and principle of operation of the thermostat of a gas boiler is to stop heating the coolant at the moment the required room temperature is reached, and after it drops to the lower value, resume work. In the simplest scheme, the thermostat closes two contacts, the wires from which are laid to the heating installation and connected to the electromagnetic gas valve.

In the working position, the latter is constantly open, when the thermostat contacts are closed, voltage is applied to the valve and it closes the fuel path of the main burner, the flame remains only on the igniter. After the temperature in the room has decreased, the voltage is removed from the valve, it opens the gas line and the burner is ignited from the igniter. With this scheme of operation, the thermostat is connected to a gas boiler as shown in the figure.

To maintain the required temperature in the premises, the following regulators are used:

• A simple thermostat with a manual temperature gauge and a wired connection. Complete with wires up to 30 m long.
• Controller with display and programming capability, complete with wires for connection.
• The same, with a built-in GSM - a module for communication with a mobile phone.
• Autonomous wireless controller.
• An external wireless thermostat for a gas boiler that allows you to control its operation depending on weather conditions.

The last type of thermostat is used in conjunction with an electronic control unit for a heating installation that has this function. Most of the leading foreign manufacturers provide for this possibility in their products. The weather-dependent regulator is connected to special contacts of the controller or communicates with it via a radio module. This method of regulation is considered the most effective, since the boiler installation responds to cooling (or warming) even before the cold penetrates the house and the temperature in the rooms begins to drop.

You can set the required temperature in the house if you put a programmable thermostat for the boiler with a display. Depending on the manufacturer, the electronics of the device can be programmed for a week or more in advance so that the required temperature is maintained in the house at different times of the day. The function makes it possible to save fuel, since it makes no sense to fully heat the house when there is no one in it. The same applies to the night time, during sleep, the temperature can be lowered by several degrees, and raised again in the morning.

A thermostat with a GSM module can send information to your phone using text messages. In gas boilers of leading European and South Korean manufacturers, Wi-Fi modules are installed, with which you can control the operation of the unit via the Internet. Since the controller of such heating installations is connected to the room thermostat, it is possible to remotely change the temperature in the premises of the house through the network.

There is a novelty in the boiler equipment of some leading manufacturers. For remote control of all functions of the unit, special applications have been developed that are installed on a smartphone.

Wireless thermostats for boilers are equipped with a built-in radio module for communication with the boiler controller. Ease of use and the absence of long wires are the main advantages of these devices. The disadvantage is that heating units and thermostats from different manufacturers may not be compatible with each other. The regulators connected to the boilers with wires also suffer from the same drawback. The problem arose due to the abundance of various manufacturers of electronics and gas equipment. For this reason, it is necessary to buy the device after consulting with a specialist in the service department of the manufacturer of the boiler and thermostat.

Various additional automation for gas boilers, including thermostats, have an increasing number of functions, their range is constantly expanding. Some models with a large LCD display can not only maintain the temperature in the room, but also control the gas burner device together with the boiler electronics. On the display, you can see the temperature of the coolant and the outside air, and in the event of an emergency or minor malfunction, an error code will appear on the screen. These electronic devices eliminate the need to frequently visit the furnace room in order to check the operation of the equipment.

Conclusion

The cost of thermostats cannot be called high, but with their help you can significantly save any fuel that is used in your boiler room to heat your home. At the same time, there is an additional convenience in the operation of the entire heating system.
