And other companies that operate on gas allow you not only to heat your home, but also not to spoil your appearance interior of your home.
All the items included with these wonderful heating devices are considered by many to be unnecessary nonsense and are called “accessories”, which can be completely dispensed with. The boiler heats the water to the required values, then, when the coolant cools down, it turns on again and brings the water temperature to the level you need.
You determine this level yourself, and the device’s task is to turn on every time to support the program you set. The boiler is manually adjusted by you and is “responsible” for heating the water, but the air temperature in the room is not its task.
What should you do if suddenly the air warms up above the set norm due to the sun’s rays, or in cold weather it cools down to uncomfortable temperatures?
Option one is to do nothing and let the boiler itself, turning on and off countless times, heat the coolant.
Option two is to purchase a device called a room thermostat for gas boiler, thereby guaranteeing warmth and comfort to your home and protecting a rather expensive heating device from rapid wear and tear, in this case boiler.
Mechanical room thermostat
Room thermostat or the thermostat certainly cannot be classified as an unnecessary accessory, because... This device regulates the operation of the boiler and ensures the heating of air, not water, and for this, as you remember, the boiler is not responsible.
Water cools much faster than air and the boiler needs to be turned on approximately once every ten minutes to maintain the required temperature. The pump of the device works in this mode without ceasing and wears out quite quickly.
What happens to the boiler to which the room thermostat is connected? Let's figure it out in order to draw a conclusion about the need for this device or its complete uselessness.
Operating principle of a room thermostat
A room thermostat is a modern compact device that allows you to control and regulate the air temperature in the room, the value of which you determine yourself. In some European countries, for example, this device is considered mandatory for installation in any home, and I think there is no need to explain how Europeans can save on literally everything.
So, when the air temperature drops by at least 0.5 degrees, the thermostat gives a signal to the boiler to turn on, and it accordingly heats the water, raising the air temperature to the required numbers.
If the temperature remains at the level of the indicators you have determined, the boiler does not turn on, saving gas and electricity so much that the payback of the device itself occurs very quickly.
Gas and electricity bills constantly surprise us in terms of growth, and I think it would not hurt anyone to save up to 25-30 percent of the family budget just on the operation of the thermostat. This is such an “accessory”!
What about the boiler's operation? Can you imagine how much less often it will need to be turned on if the thermostat controls the operation of your heating equipment? The service life of the boiler is doubled.
Let's determine the advantages of a room thermostat:
— the device maintains the desired temperature in the house, creating an atmosphere of coziness and comfort;
— when connecting a thermostat, there is no need to constantly monitor and regulate the operation of the boiler;
- saving money and quick payback for the device.
Main types of thermostats
Room thermostats can be divided according to the method of influencing heating equipment (in this case, a gas boiler) and according to the quantity and quality of the functions they perform.
According to the method of regulation, thermostats are divided into 2 types:
- wired;
- wireless.
For the first type, it is necessary to connect the device directly to the boiler, and thermostats of the second type monitor its operation using a radio signal.
A wireless thermostat contains two devices at once, one next to the device, the other in the room from which temperature control will be carried out. The devices are connected to each other via a radio signal.
Room thermostat for Baxi boiler
The unit, located in the room, is equipped with a display on which you indicate the desired air temperature in the room, i.e. program its operation. That is why these types of thermostats are called programmers.
Features of room thermostats for boilers
According to the set of functions they perform, thermostats are also divided into two types:
- simple or mechanical;
- programmable.
Simple room thermostats have one function - they maintain the required air temperature, that is, they perform their main role. Programmable thermostats are capable of interfering with the operation of the boiler even from a distance.
You can set a program for such a device for a week and a month in advance, you can change the temperature from day to night, you can program the device in such a way that the house will greet you with warmth exactly when you arrive after work or after a long business trip.
If you have already decided to purchase a room thermostat for your boiler, but are not looking for high prices, start with the simplest model, and only when you realize that you really need the device, purchase a more complex design.
Also, analyze the conditions of your room: it happens that wired devices simply cannot be connected in a given room, then your choice will be limited only to wireless thermostats.

Recommendations for selection and installation
When purchasing a device, get a qualified explanation from a specialist and use some tips:
1. It is better if you purchase a thermostat from the same manufacturer that made yours. In this case, installation and installation will be easier and control over gas equipment will be more reliable. Although many people buy various devices that successfully function for quite a long time and well.
2. Be sure to consider the size of the room in which the device will be installed and the temperature it will control.
3. It will not be at all superfluous if an additional layer is laid in a room equipped with a thermostat; in this case, your savings in material resources will increase significantly.
4. Since the room thermostat is “responsible” for the air temperature in the room, there are a number of restrictions in its use, which we list below:
— do not install the device next to objects that prevent free air circulation;
- do not cover it with decorative elements such as shelves, curtains, etc.
Programmable thermostat for gas boiler
Connecting a thermostat to a gas boiler with your own hands
According to the principle of operation, a room thermostat is very similar to a car thermostat, but, unfortunately, the latter cannot turn off the engine internal combustion, and the room thermostat will turn off at the right time, preventing it from overheating the air in the room.
Many are stopped by the fact that to install a thermostat it is necessary to call a competent specialist, but this is completely optional. You can safely install the device yourself if you take into account some recommendations:
— before starting work, it is necessary to drain all water from the system by opening the inlet valve;
.
— purge and disconnect the adapter;
— tighten the nuts located between the adapter and the valve, ensuring that the threads are intact.
The basic rule for operating a room thermostat is to protect it from any mechanical damage, because this can cause a lot of damage sensitive elements instrument sensors.
Each room needs a separate one; take this fact into account when calculating the financial resources that you intend to allocate for the purchase from your budget.
Each room has its own temperature - higher for the nursery, slightly lower for the bedroom, etc. Make sure that the doors between rooms are tightly closed, otherwise the operation of the device will be difficult. Let's watch the video.
Manufacturers and prices
As for the price of thermostats, for example, the simplest device for a boiler from Baxi or Protherm will cost you 35-45 dollars. At the current rate, it’s a little expensive, but don’t forget that the device will pay for itself soon enough, and the savings on electricity and gas will also be noticeable. The choice is yours!
Modern gas boilers are highly technologically advanced and most often have a built-in A thermostat is a device that measures the temperature and humidity of the air in a room and sends signals to the boiler board on how to heat.
Adjustment occurs by turning the boiler power on and off. However, there are situations when you have to connect additional control equipment.
How to connect a room thermostat to a gas boiler?
For mounting the regulator no professional skills or special tools required, it is enough to understand the installation diagram, follow the instructions of the manufacturer of the gas boiler and regulator, and observe safety precautions for working with electric current. Then the installation can be done independently, without the help of a specialist.
Connection diagram
The diagram of the gas boiler must indicate whether it is possible to connect a thermostat to it. It is important to ensure that the installation additional equipment allowed by the manufacturer and won't do any harm heating system.
Incorrect installation may cause damage expensive equipment and loss of warranty.
In the case where the control unit will be installed inside the boiler, find a suitable place for it. If necessary, you can use an installation box.
Important! When connecting the thermostat fulfillment of manufacturer's requirements boiler is strictly necessary!
If you study main board diagram gas boiler, it is clear that it has two contacts connected by a jumper, Where electricity first leaves the board and then returns to it, controlling switching on and off heating boiler. In many modern models For ease of installation, this jumper is located on a separate terminal block, where the thermostat is simply connected.
Photo 1. Printed circuit board of a gas boiler. The part circled in red shows the possibility of connecting various thermostats.
But on some types of heating equipment you will have to look for the installation location directly on the board. In this case unscrew the screws that hold the jumper, take it out, and in this place install wires, going to the thermostat.
A correctly connected thermostat passes through itself an electric current going to the boiler from the network, thus controlling the switching on and off of the entire system heating. If the air in the room is heated more than what was set on the regulator during its setting, the device turns off the gas boiler, and when the temperature drops below the specified limit, the heating turns on again and the air in the house is heated.
Materials and tools
To install a thermostat to a gas boiler, you do not need any special tools. Everything that is needed to install the device in the heating system is included in delivery kit.
To install the regulator you will need technical passports thermostat and heating boiler for reconciliation electrical diagrams connections, household screwdriver, voltage tester online, fastening tool kit device on the wall in a living room.
Choosing a location to install the thermostat
Before the beginning installation work choose the location for installing the thermostat. Choosing the right room for the device is extremely important., because it is based on the temperature and humidity of the air in this room that the entire heating system in the house will be adjusted.
The thermostat must be installed in a residential area, not in a technical one. Usually choose the most cold room throughout the house, for example, a corner one. Installing the device in a boiler room or pantry will lead to incorrect heating operation. Do not hang the regulator close to heating batteries , household appliances emitting thermal noise: stoves, heaters. It is not recommended to place the regulator in a draft, near windows, or where it will be exposed to direct Sun rays.
The thermostat should be easily accessible and visible so that you can change the temperature settings or replace the batteries at any time.
Rules settings:
- Mounting height no more than one and a half meters above floor level.
- Do not install externally, cold wall of the house.
- To the device there must be free access.
- Do not hang near stoves, air conditioners, or windows.
- Avoid direct sunlight to the device.

Preparation
Before installing the thermostat, you must make sure that the boiler supports the installation additional equipment. Then the heating system is disconnected from the electrical network and the voltage is checked with a tester.
Attention! When installing the regulator, all equipment first disconnected from the electrical network!
After preparing the room: provide free access to the thermostat installation site and to the boiler, sufficient lighting of the working areas.
Installation and connection
All modern gas boilers have special exits for connecting a thermostat. The regulator is supplied with a special mounting cable or mounting using a terminal. If this model has a non-standard connection, then it comes with technical certificate, where there are all detailed installation diagrams.
Photo 2. Detailed diagram thermostat TS2 GMS, showing its connection to the boiler and other equipment.
The connection is to screw the ends of the wires thermostat to terminal boiler, and then install the device on the wall in the living room. As a rule, the instructions have a corresponding section with detailed instructions for installing a thermostat.
Start up, check operation
After connection, the regulator and boiler are started for testing. In that instructions will help, which comes with the regulator in the kit. The thermostat usually runs on batteries; you need to make sure they are inserted into the device and charged.
If the regulator is turned on, the boiler is also connected to the power supply. Using the buttons on the regulator display, you can set various parameters and observe whether the heating system responds to changes. If it works correctly, then fine tuning is performed.
Heating settings
Carry out in accordance with the instructions in the passport regulator In order to ensure the correct operation of the heating system, follow the rules:
- If the house remains empty for a day or more, then during the absence of the owners they exhibit minimum temperature.
- Before a long departure, for example, in case of vacation, fresh batteries are installed in the regulator and switch the system to economy mode.
- It's important to take care of your batteries and prevent their discharge by making timely replacement.
- Boiler and regulator connected through a voltage stabilizer.
Most thermostats there are already pre-installed programs, which will ensure optimal heating of the room during the day and saving resources at night. The number of such programs depends on the device model. You can choose one of them, or configure the device individually.
Thermostat is a thermoregulating device that is responsible for control of boiler operation depending on air temperature.
There are thermostats indoor and outdoor(street). Sensors can also be used for the street.
Baxi gas equipment has the ability to connect both indoor and outdoor thermostats and sensors.
Room appliances have a greater impact on tactfulness(turning on and off) the boiler, and outdoor ones allow the unit to regulate coolant temperature. The air temperature outside and in the house is constantly changing, and the thermostat helps increase or decrease gas consumption for space heating.
Types of thermostats for Baxi gas boilers
Devices for Baxi are thermostats compatible with gas boilers of the Italian brand.
In terms of their functions, they do not differ from systems for other gas equipment. Typically, thermostats are distinguished by:
- installation location;
- operating principle;
- control method.
Depending on the location of installation, devices are divided into indoor and outdoor. Indoor ones are used more often than outdoor or street ones, as they do not require protection from difficult weather conditions.
Street options are used in cases where the owner of the house strives 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 Baxi units allow.
According to the principle of operation, the thermostat can be mechanical or electronic. In the first case You must manually set the air temperature. In the second— a program is installed according to which the boiler changes its operating intensity automatically.
Control method mechanical thermostat is manual installation regime turning the knob or pressing the buttons. The electronic or programmable option can operate remotely. In this case, the sensor is located in any part of the room, and control occurs from the 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 Baxi boilers produced by the Italian company itself, so it’s best to choose them. If this is not possible, you need to look for a thermostat that matches the parameters that are usually specified in technical data sheets of devices. In such cases, it is appropriate to consult a specialist who is well acquainted with the Baxi brand.
Attention! Check carefully compatibility thermostat with the gas boiler for which it is purchased. Remember that devices one company interact best with each other.
When choosing a thermostat, it is necessary to consider whether the boiler is used constantly or only occasionally. If the house has an inexpensive model of the unit that rarely works, then it is enough a simple controller with a minimum of functions.
And vice versa, if heating and hot water are needed all year round and an expensive unit model is used, it is better to install a programmable thermostat.
And if the cottage is involved system " smart House» , then the ability to control the device via the Internet will be very useful.
This feature is implemented in most advanced models.
Calculation technical requirements to the thermostat is made based on the requirements for the operation of the boiler. For example, if the owners go to work in the morning and return only in the evening, it will be suitable 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 for the system: it automatically turns on the boiler if the air temperature drops up to +3°C. Such technical characteristics has, for example, room thermostat Baxi Magictime Plus.

Where to post
An important condition Correct operation of thermostats requires accurate measurement of air temperature. Although all devices have errors up to several degrees, it can be minimized.
For this room thermostat you need to install 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 indicators, those work more efficiently boiler and lower fuel consumption.
What materials are needed for connection
Connection materials are usually supplied with the thermostat. This is, first of all, the device itself, as well as installation 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 the remote thermostat.
A drill is needed for the holes in the wall into which the dowels are installed. They get twisted in screws, on which the device is attached. Need for dowels disappears if the wall is wooden.
A thermometer will be needed to check the air temperature after starting the thermostat.
Connection procedure
During the connection period, both devices should not work. To connect the thermostat and gas boiler, you need to study technical data sheets of both devices and follow the wiring diagrams and instructions. The ends of the cable for the thermostat must be attached to the designated gas boiler contacts.
Then the cable must be pulled along the wall to the location where the thermostat is installed. After this, at the selected point (usually it is in the coldest living room), 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).
Once a comfortable temperature is reached, you need to accurately measure it next to the thermostat and set it as a threshold for turning off.
An integral part of the heating system modern house is automatic control equipment. Among owners of houses, cottages and apartments, room thermostats and programmers are becoming popular, which allow them to control energy consumption by maintaining a comfortable temperature.
Types of thermal control in heating systems
Regarding the principle, thermal regulation is carried out in three types:
- by coolant temperature;
- by air temperature in the room;
- on heat loss of a home.
Coolant temperature regulation is relevant for houses with an area of less than 60 sq.m. This method is used in most modern homes. Based on the information received from the temperature sensor, the operation of the boiler burner is stopped or resumed. Regulation is carried out by setting the desired temperature mark on the boiler equipment panel.
Regulation of indoor air temperature is acceptable for dwellings with an area of 60-350 sq.m. Manufacturers produce thermostats of various modifications - with the ability to install programs, wired, wireless, etc. Using a thermostat can reduce energy costs by up to 25%. In premises with an area of more than 350 sq.m. professionals recommend installing weather-sensitive automation. In this case, the boiler equipment will replenish heat losses Houses. A special sensor reads the temperature outside and regulates the operation of the boiler based on these indicators.
Features of room thermostats
Before you buy a room thermostat for a gas boiler and an electric boiler, you should carefully understand the mechanics of such a device. A room thermostat is a device for automatically regulating the operation of boiler equipment in accordance with the air temperature specified by the consumer. The thermostat is equipped with temperature sensors that are installed in an area remote from direct impact heating devices. Information from temperature sensors is fed to the thermostat. A room thermostat monitors the air temperature in your home. The equipment does not allow the room to overheat or overcool. Thanks to this, energy is significantly saved and a comfortable microclimate is created in the home.
A room thermostat is designed to maintain a set room temperature relative to a pre-programmed schedule. Regulators can control the operation of boiler equipment, heating radiators, water heated floors and other heating devices.
Depending on the heating device connected, room thermostats have some design features. For example, a thermostat for boiler equipment must have a relay output of the “dry contact” type. For electric heated floors, thermostats with a power relay are used.
Types of thermostats
Regarding connection, thermostats are divided into two classes:
- wired;
- wireless.
A wired thermostat uses a cable to transmit the signal. The cable also supplies power voltage. Wired thermostats are different affordable price and are often used on sites where the fine finishing, there is a need to lay a cable from the heating device.
In those houses where the renovation is completely completed, it is more rational to use wireless thermostats. The devices supply a control signal to a slave receiver via a radio channel. Wireless devices consist of two functional blocks. The first is represented by a controller with an LCD screen and a keyboard for ease of operation. The second block is the actuator. The first block is placed in any convenient place in the home at a distance of up to 50 m from the second receiver block. The second unit is installed directly next to the boiler and connected to it.
The wireless room thermostat for the boiler has an operating range of up to 30 meters. In the event of signal loss, the built-in microprocessor controller is able to operate based on data stored over the last 24 hours. The accuracy of temperature control of the device is within 0.2 °C. The control here is simplified to two function buttons (increase and decrease temperature).
According to their functional component, thermostats can be programmable or non-programmable. By programming the thermostat, you can set the temperature for each day at specific time intervals. This temperature change schedule will allow you to significantly save on heating costs. Non-programmable devices maintain a constant temperature. They are able to manually switch day/night modes or support the anti-freeze function.
Programmable thermostats come with a variety of useful features. For example, the “vacation” option provides energy savings by reducing the temperature when people are away for up to several days. After disabling the function, the thermostat returns to normal operation.
Most modern devices are digital wireless thermostats. They connect to external devices via a radio signal at a frequency of 868 MHz. Due to wireless technology, the devices become mobile - they can be moved to any convenient place without the need for installation electrical cables. To organize a complex configuration, zonal control is used. In this case, the room is divided into separate temperature zones, and an individual program is set for each of them.
Benefits of using a room thermostat:
- opportunity remote control boiler equipment;
- ability to change heating and cooling modes;
- automatic maintenance of a comfortable temperature in the home;
- saving up to 40% coolant.
Installation Requirements
The room thermostat should be located in an area with good air circulation. It is mounted on interior wall, at a height of about 1.5 m from the floor. The thermostat should not be placed in a drafty area, near heating devices, or in places exposed to direct sunlight. Places with high level moisture condensation. Since wireless devices are radio frequency, they are placed in open spaces. The devices must be installed at a distance of at least 30 cm from any metal objects and electrical equipment.
Room thermostats for boilers
The price of boiler equipment depends on the complexity of the development. Main factors influencing cost:
● installation method (the simpler, the more expensive);
● control method (remote or wired);
● ability to adjust the temperature range;
● complexity of automation (self-adaptation or custom mode).
Assortment of thermostats in the SantekhMarka online store

A thermostat or programmer can be connected. These devices help to automatically regulate the temperature in the house or turn the boiler on and off at a given time.
Mechanically controlled boilers do not have the ability to connect an electronic thermostat.
Most often there is a need to maintain the required air temperature in a room without human intervention. A room thermostat is used for this purpose. In the article we will talk about the operating principle of this device and explain how to connect a thermostat to a gas boiler.
Benefits of using the device
If we already talk about the advantages, then we will describe the difference between the operation of a boiler with and without a thermostat.
Without thermostat
How does the boiler operate in normal mode? We set the desired temperature with the control knob and enjoy the warmth. But what happens when it gets cold outside? The temperature in the room also drops. It didn’t seem to be a big deal - I went and set the boiler to a different temperature setting. It became hot - reduced it, and the boiler continues to work, turning on and off.
With thermostat
Now let's imagine how a boiler works with a electronic thermostat. The boiler will heat the coolant until the room temperature reaches the set temperature and only then turn off. It will not turn on until the air temperature drops below the set limit. Then the process is repeated again.
Advantages
By installing even the most primitive thermostat, you can save from 15 to 30% of gas.
The automation of the room heating process itself is already a significant advantage, but some other points can be highlighted:
- The boiler will not turn on if daytime throughout the year, the sun's rays warm the room and maintain the desired temperature.
- There are many people in the room and because of them the air temperature does not drop.
- The boiler automation wears out less, as switching on occurs less frequently.
- There is no large temperature difference in the room, since the minimum thermostat threshold can be 0.25°C.
- Ability to change settings.
- After turning off the boiler circulation pump It works for some time, preventing boiling of the coolant, and does not turn on until the boiler starts working.
- Anyone can handle the settings.
If we talk about the disadvantages, we can highlight only one - in a wireless thermostat you need to periodically change the batteries, a supply of which should always be on hand.
Even this brief overview This is enough to understand that purchasing and installing a thermostat is a wise investment that will more than pay for itself in a short period of time.
Device selection
The choice of device must be approached intelligently. Often people buy a device with a considerable number of options that they then never use. What to consider? Let's look at this in more detail.
A remote thermostat can be wired or wireless.
- The presence of a wire eliminates the need for batteries, but such a connection will bring a lot of other problems when the device needs to be installed in an adjacent room. Do not lay the wire along the wall or drill a through hole for it. The best decision for a room after renovation (or if there are no plans to carry out renovations there in the near future).
- The wireless sensor not only does not require connection, but can also be moved to any other room. Even before purchasing, it is important to know the range of the device and how it works through walls. For example, some cheap sensors work reliably only in the line of sight, but if the situation changes or if they are far away, they may lose the ability to transmit a signal to a module installed near the boiler.
- Purchasing a device from the same company that manufactured the boiler will help you avoid some connection problems.
As already mentioned, it would be good if the device was purchased for an installed boiler from the same manufacturer. Most good combination It turned out from the famous brands Baxi (baxi), Protherm (Proterm) and Vaillant (Vailant). In the illustrations below you can see the variety of these devices.
Adjustment method
Controls can be:
- in the form of buttons, and all data is displayed on an electronic display;
- Mechanical control implies the presence of a regulator with indicators printed on it.
Functions
Thermostats can be simple or multifunctional.
- Simple device can only maintain the room temperature preset in its settings.
- Programmable thermostat has a rich set of functions. It can be configured by changing the boiler parameters remotely by setting the required temperature conditions V different time days. You can also set settings for each day of the week.
- Thermostat with integrated hydrostat function will allow you to control, maintain and change the microclimate of the room by changing the humidity level.
About the manufacturers
Thermal sensors from IMIT and Siemens are very popular. They differ not only in functionality, but also in the connection method. It is quite clear that more functional models are more expensive. To make it more clear, we made a comparative analysis, the results of which you can see in the table below.
The cost of the product is given in rubles, but only for comparative analysis. Since prices are constantly changing, at the time of purchase, accurate data can be obtained on the manufacturer’s website or from the sales company.
Installation and connection
And now, when the equipment has been selected and purchased, you can begin to install it. First, let's look at recommendations for sensor placement.
Choosing a location for the sensor
The correct and efficient operation of the entire heating system depends on where the sensor is placed, so the following rules must be taken into account:
- The recommended installation of the sensor above the floor is 1.5 m. We all know that the room is heated unevenly with any heating system, be it classical system or heated floor. If you neglect this rule, the sensor will control the boiler in a different temperature mode.
- It is not recommended to attach the sensor to external wall, since it is always colder than the walls inside the room.
- The sensor does not need to be installed in a remote place or hidden behind any objects - air should circulate freely near it. But you need to beware of the other extreme - the device should not be in the area of drafts.
- The place for installing the device should not be near heating devices or near air conditioning, windows or entrance doors. It should not be exposed to direct sunlight.
Such an abundance of restrictions and regulations may seem too much, but in fact there is nothing complicated here, you just need to remember this when choosing a location for the thermostat sensor.
First of all, you need to disconnect the boiler from the power supply in order to protect yourself and the boiler electronics when performing work.
If the control unit will be installed inside the boiler, then you need to find a appropriate place. If there is such a need, you can use an installation box to mount the unit.
In order to connect the control unit to the boiler, you do not need special knowledge, but you will have to understand the circuit.
The red arrow shows the current path through the circuit. Entering pin L, it passes along the board and leaves it through pin Tb2, in which a jumper is installed connecting it to pin Tb1. Through this contact, the current returns to the board and controls the operation of the boiler, turning it on or off.
Now you need to download the diagram of your boiler from the Internet and check whether it has the ability to connect a thermostat. If you find the inscription “Room thermostat” on it (in different models boilers, the name may be slightly different), which means it is possible to connect a thermostat.
If you have a floor-standing boiler, then this check must be performed before purchasing a thermostat.
Let's return to the jumper installed between contacts Tb1 and Tb2. In many boilers it is located on a separate block (photo above), but in some models you will have to look for it on the board.
Having unscrewed the screws holding the jumper, you need to pull it out, and instead screw in a 0.75 m 2 wire that will connect the boiler board to the thermostat control unit (or to a wired thermostat). As you can see, in the diagram the thermostat contacts are open.
According to the thermostat circuit, we need a pair of normally open contacts - these are COM and NO. Usually this is the marking that is present on the connected unit.
If the block has different markings or is missing at all, then the contacts can be checked with a tester. One electrode is pressed against the middle contact, and the side ones are checked in turn with the second. We need a pair of open contacts.
Depending on the design, the unit is connected to the network or batteries are inserted into it.
Adjustment
You need to check how the thermostat behaves. For this purpose, it displays certain parameters, and see how the boiler reacts to the commands sent by the thermostat. If everything is in order, then you can perform the final setup. How to do this is described in the product data sheet.
To ensure that the system works correctly and without failure, take into account the following recommendations:
- If you work shifts, it is better to purchase a programmable thermostat and adjust it so that the minimum permissible temperature in the room is maintained during your absence.
- When going on vacation or leaving home for a long time, switch the heating to economical mode and, just in case, install fresh batteries in the device.
- Don't wait until the batteries become unusable - change them early.
- Connect the boiler and control unit through the stabilizer.
Epilogue
A thermostat will make your life easier, and by installing it yourself, you will save a lot and will know what to do with it if it breaks. We hope this article serves as a good guide for you.
