The temperature sensor for the heating

Heating boiler thermostat: classification, operating principles and features of the installation

Today thermostat (aka - the thermostat) is considered as much a part of independent heating, as well as the boiler with radiators.

Available in different versions of the device, and to choose the most suitable, the user should carefully examine their product range.

That's about it, as well as how to install and how much is the thermostat for heating boiler, will be discussed in this article.

The desired value of this temperature, the user must specify in any way provided for construction of the instrument.

In operation, thermostat with temperature sensor compares incoming data with the settings and results of the comparison generates a user input signal to the boiler control system, thereby starting it to work on or off.

As you know, due to constant changes in the air temperature outside the heat transfer of the heater also has to adjust all the time.

If you keep it on the same level, while warming in the house would be too hot, and in the bitter cold - cold.

In earlier times, adjustment had to deal with the user, but now this function took over the thermostat. Through automation, the temperature in the heated space at any weather remains in a comfortable range.

Digital thermostat Viessman

The main characteristic of the thermostat is the threshold. For most models, it is 0.25 degrees. That is, as soon as the temperature in the room will be a quarter of a degree below a user-defined, the unit will react and turn on the boiler.

Apart from the fact that the thermostat frees the user from the worries associated with the configuration of the heating system, it allows you to win the following:

  • due to timely disable the boiler fails drastically reduce the consumption of electricity or gas (savings - up to 30%);
  • the risk of accidents due to overheating or freezing of the system is reduced to zero.

Since the thermostat does not allow the temperature to drop too much, the heat generator is always running in the power saving mode, so that its life is extended significantly.

thermostats family rather motley. First of all, they are divided into two groups:

These devices are mounted directly in the boiler, or near it, and their sensor monitors the temperature of the coolant in a "return pipe". Thermostats are built cheaper than others.

But they have a major drawback: because the air temperature in the heated room is not determined directly and indirectly (through the coolant), the unit always works with some delay.

Remote or room thermostat for heating boiler

In addition to the temperature sensor within the heating circuit, these thermostats have another - the air, which is installed in a heated room.

According to the advantages and disadvantages of these models are strictly opposed to embedded: have a higher price, but comfortable temperature is maintained at the highest possible accuracy.

Remote thermostats are available in two versions:

  1. The device is fully installed in the room and connected to the boiler by means of a long wire.
  2. The device consists of two parts: the sensor with radioizluchatelem installed indoors, and the controller with tuner - near the boiler, while connected to it via a short wire. Communication between the temperature sensor and the controller is carried out via radio.

The operating principle of all thermostats can be divided into the following types:

  1. analog: This is the simplest kind. the temperature sensor is based on changing the volume of the substance with increasing or decreasing temperature - it may be liquid in the flask (capillary sensor) or a combination of materials with different coefficient of thermal expansion (bimetallic strip). Analog thermostat is equipped with a mechanical knob to adjust the temperature, which is connected to a rheostat or variable resistor.
  2. Digital: as a temperature sensor used in such a device a semiconductor element that changes electrical resistance value with changes in temperature (a thermistor). Such elements are of two types: NTC and PTC. In the first resistance during heating is reduced, the second - increases. But the principle of the temperature sensor - is not the main difference between digital thermostats.

Unlike analog, digital devices equipped with a chip: it displays information about the work of the display mode and provides more opportunities for setting up the device.

For example, in the thermostats of this type usually has a programming function.

When compared with remote embedded thermostats, the latter should be considered definitely more preferred. Yes, they are more expensive, but do allow a smaller amount of gas than the built-in thermostats.

The latter, as already mentioned, some late and it therefore can not provide the operation of the boiler, and therefore the consumption of gas in the optimal range. Thus, the difference in price with the purchase of a remote thermostat soon pays for itself by saving gas.

Choosing between digital and analog thermostats must accurately assess their own financial capabilities. If funds allow, it is better to purchase a digital device. It is available in the programming function is extremely convenient.

Thermostat programmable room

You can, for example, specify the following settings:

  • on weekdays 7-30 am (when all members of the household go to work) to lower the temperature in the room to 18 degrees;
  • 17-00 (an hour before returning residents of the house) to heat the room to 24 degrees;
  • a day to maintain the temperature at 24 degrees around the clock.

Of course, buying a digital thermostat is not always feasible. If, for example, a user works at home (many now work via the Internet) and the requirements for the temperature regime during the day remain constant, it is wise to buy an analog-type device.

When used as an unprepared coolant water (not the last desalting procedure) in the heating circuit is better to set the analog temperature sensors, since the accuracy thermistors with scum fouling decreases strongly.

The choice of thermostat can be influenced by some circumstances not connected with the heating. For example, the repair stage.

If at the time of purchase of the device you are doing interior renovation or are planning something like this, it is advisable to purchase a remote thermostat with wired connection: cable can easily be hidden pave the way.

If the repair has finished, the hidden seal would be too expensive (in the house again have to arrange devastation), so the best choice would be a thermostat with radio. However, it should be borne in mind that the walls can sometimes interfere with the passage of the signal, so it is important to check before installing the quality of communication between the individual modules.

When choosing a device, you should pay attention to the various useful options. Very convenient to use thermostats are equipped with remote controls. And to those who are often faced with power outages, it makes sense to buy a model with a built-in batteries or powered by batteries.

To simplify the installation and configuration, choose the thermostat of the same brand as the boiler.

The remote thermostat mounted in any of the living rooms, usually the coldest (usually one of the corner), or the most visited, for example, in the living room. When installed in the kitchen, hallway or boiler, the device can not provide the correct operation of the heating system.

To readings were as objective as possible, it is necessary to minimize the influence of thermal noise.

These include:

  • Sun rays;
  • drafts;
  • thermal influence from home appliances or heating radiators.

Do not forget that the cold air settles down, whereas the heat rises to the ceiling.

Therefore, the thermostat should be placed as low as possible. Also, you should avoid installing it in a confined space, such as behind the curtain, or in the narrow gap between the pieces of furniture.

To know exactly where the boiler is located terminals for connection of the thermostat and other equipment, should carefully examine its datasheet and user manual. There you are wiring diagrams and recommendations relevant for this particular model of boiler.

Installation and connection of the completion of the thermostat must be configured. The procedure is set out in the instructions to the device. At this stage thermostat memory such data are entered:

  1. The desired temperature.
  2. The allowable temperature drop. If, say, at a set temperature set at 23 degrees difference of 2 degrees, the thermostat will include at 22 degrees the boiler on and off at 24-x.
  3. Trip delay.

With the last setting device will not react every time he, for example, a short time will be a draft or cast out by something hot.

The thermostat allows you to regulate the temperature in the room. Thermostat infrared heater - a device and connect to the heater, as well as an overview of the prices of the instruments.

Thermostats with room sensor - how to choose the mechanical and electronic for the house or a sauna

Heating homes, apartments, offices and other facilities is an important task, whose solution requires a competent and thorough approach. Often used for this purpose different gas and electric heaters with built-in automatic control functions. For this, use temperature controllers to air temperature sensor (thermostat), a built-in electric external or option which has recently become increasingly popular.

What thermostats with air temperature sensor

Thermostat (aka thermostat) having a temperature sensor in the room, a special controller, which is an essential part of the heating control device. The main task of the device is to support the coolant temperature at a specific level for cooling or heating. In most cases the desired temperature setting is made manually, whereupon the thermostat automatically controls the operation of the boiler or the convector.

Sometimes thermostat is part climate equipment, for example electric boilers, air-conditioners. He is, first of all, you need to increase the comfort level. Due to the temperature controller do not need to constantly disconnect and turn on the boiler, measuring changes in temperature in the room - all described functions are performed by the device automatically. In addition, it is necessary to:

  • Security software. If the boiler is for some reason did not shut down after the automatic control signal or overheating occurs, the thermostat will notify the owner about it with the help of sound.
  • Savings. The thermostat can save on heating and cooling system by controlling the air temperature, due to which decreases the consumption of gas or electricity.

Mechanical or electronic temperature regulator via boiler thermostat collects information about the current temperature indicators directly in the coolant. Room sensors thus measure the inside of the room. Then, the collected information is sent to the control unit device or on an automatic controller for storage and use. After verification of indications received from sensor controller in accordance with settings either reduces or increases the temperature of the boiler. He turns off the heating system as required.

How to choose the thermostats with air temperature sensor

To start, decide between the electronic and mechanical devices. The first option is more optimal and convenient, but if you are at home or in the office are intermittent problems with electricity, then give preference to a mechanical device. Next, pay attention to the limits of regulation, the method of installation (the simpler the better) and the degree of dust and moisture protection.

Especially thrifty buyers better to buy a programmable thermostat. This is due to the fact that a particular temperature regime is needed in the house around the clock. During business hours the premises are empty, so spend the money once in a programmable device, you save considerably on utility bills in the future. Weakening can be programmed heating, e.g., from 10 to 16 hours.


Bought thermostat TR 515 from Teplolux. Optimal variant for stable operation temperature floor heating. The accuracy of maintaining the predetermined parameter is 0.5 degrees. Purchase cost is not so expensive - only 2,700 rubles. Is a function of self-diagnosis and protection of children. Deficiencies were found.

For heating systems ordered thermostat with a programmable touch controller SST SE 200. There is a remote sensor is mounted recessed installation method. I note a very convenient control and easy setup. Dust and moisture protection is not so high - only IP21, so I think this is a disadvantage. It should be a little expensive device.

A brief search led me to a device Teplolux TR 520. The thermostat has a modern appearance, a large display and good technical parameters. After purchasing it turned out that the device does not turn off the system "warm floor" in the "End Call" mode. In addition to the poorly functioning firmware omissions of note is not very good build.

Existing temperature sensors for heating

Temperature sensors are needed to convey information about the current state and the current coolant temperature controlled facilities. Data from the sensors are sent to the controller which processes the information received and generates a control signal for adjustment of the heating boiler.

All temperature sensors for heating, which are used to control loop current state, are separated into 2 types. In principle, the full control of the heating system will provide any of them, the difference is in the use of various design solutions and data transmission method.

information transmission methods are divided into the following types:

Wire temperature sensors for heating, and it is apparent from their names, the data is transmitted to the controller via wires routed from the sensor to the control unit of the boiler. High-tech wireless sensors transmit information by using radio wave transmitter and receiver. Approximately as working router WiFi.

Temperature sensors according to the method of their placement are divided into these types:

  1. Overhead sensors - are fastened to the pipes of the heating circuit;
  2. Submersible sensors - are in constant contact with the coolant;
  3. room sensors - are located indoors;
  4. external sensors - are placed outside the heated rooms.

How long should the thermal sensors for heating?

If the conventional heating circuit is used, only one room temperature sensor for a gas boiler, that can be multiple heating with radiation collector circuit of such sensors. In this case, temperature control takes place for each room individually. Heating temperature sensor located in each room, sends the information to the controller, which, via the control unit controls independent flow of coolant from the reservoir to the desired premises to maintain the set temperature. For more details about automatic boiler can be read in our article "The existing equipment for heating boilers."

Visual temperature monitoring

To control the temperature of the coolant, the temperature inside and outside of the heated space temperature sensors are of different types. For visual monitoring of the majority of room thermostats are equipped with displays, on which the current value of the room temperature. The temperature measuring devices that are installed on boilers, also provides the possibility of visual control.

For heating systems are used these types of thermometers:

  • Liquid thermometers. They are used for monitoring and measuring the temperature indoors and outdoors.

The solid fuel fired boilers are sometimes used for heating liquid thermometer, bimetallic temperature but the indicators used in modern units.

Faults gas boiler associated with temperature sensors

Reasons that cause a failure or intermittent operation of the gas boiler lot. In each case it is necessary to deal specifically.

The basic malfunctions of gas boilers are:

  1. the boiler does not start;
  2. attenuation burner;
  3. Gas boiler does not reach the temperature;
  4. the boiler is not disconnected.

Can these faults occur due to failure of temperature sensors? You may, and in the search for the causes of the temperature sensor failure, their chain, transmitter and receiver for wireless systems need to check the first. We can not exclude the following options:

  • The boiler has shut down and is not included. One of the probable causes of failure or scorching temperature sensor switch relay. In complex systems with electronic sensors and controllers often there is a fault in the control unit.
  • Fault - attenuation burner, may have many causes, but one of them - the temperature sensor failure, which causes the main burner off.
  • The reason insufficient heating the coolant may be premature shutdown of the boiler due to incorrect installation or temperature sensor malfunction.
  • If zalipnet mechanical temperature sensor relay or failure occurs in the electronic unit or a temperature sensor, such a failure is quite likely.

Thermostats (more details of which can be read here) together with controllers, and control units maintain a constant temperature, which contributes to fuel economy and reduce heating costs. Temperature sensors allow completely automated control of heating process and ensure its durability and safety.
