Thermoregulators with an air temperature sensor

Thermoregulators with an air temperature sensor are devices that are used to monitor and control gas and electric heating devices with an automatic control function built into them. With their help, you can maintain a set temperature in the room. And the thermostat will control this process, depriving you of the inconveniences associated with constant manual temperature maintenance in the heating device.

What are thermoregulators with an air temperature sensor

A thermostat (also called a thermostat) is a device that is responsible for maintaining a set temperature by a heating device. The thermostat is considered the main part of the coolant control. First, the required temperature is set in manual mode, which is subsequently maintained automatically by the device.

Thermoregulators with an air temperature sensor are part of a heating or cooling system. It is also integrated into climate control systems, for example, in gas boilers and air conditioners.

Installing a thermostat significantly reduces heating costs

The main functions of the thermostat

The main functions of the thermostat are:

Economy – the thermostat controls to what level the air temperature rises or falls, and, accordingly, turns off the device when the desired level is reached.

Safety – in case of malfunction or overheating of the boiler, the thermostat will notify you of this with an audible signal.

The comfort thermostat itself will take care of maintaining the required temperature in the room and will save you from having to manually turn on and off the system.

The air conditioner is equipped with a thermostat to control the air temperature in the room

One of the simplest and most familiar examples is thermoregulators for heating radiators or, as they are also often called, thermal heads for heating radiators. Such a thermostat controller is installed on the pipe of the heating device and serves to maintain the set temperature.

Useful advice! Installing a thermostat on a heating radiator is not difficult, while providing not only comfort, but also significant savings.

Thanks to the built-in thermostat on the radiators, there will always be a comfortable temperature in the room

The principle of operation of a thermorail with temperature control

The thermostat with temperature control performs its function according to the following scheme:

first, the boiler thermostat receives information about the air temperature in the coolant itself;
then the sensors collect information about the air temperature in the heated room;
all collected information is transferred to the control unit, where it will be stored;
the controller compares the received data and increases or decreases the temperature in the coolant accordingly.

The controller compares data from thermal sensors installed in different rooms

Types of sensors for temperature measurement

In order to choose the right thermostat for you, you need to understand how they differ from each other.

Thermoregulators differ among themselves in the material from which they are made, the method of installation, as well as the principle of operation and functional features.

A mechanical temperature controller is installed on the radiator

Depending on the material of manufacture , the devices are:

bimetallic (reinforced plastic);
electronic thermistors;
electronic thermocouples.

The second and third types are more common as a thermostat for a heating boiler.

Mechanical thermostat

Depending on the principle of operation , thermostats are divided into two types:

mechanical;
electronic.

The principle of operation of mechanical models is based on the expansion of bimetallic plates and data transmission to the control unit. Electronic models function thanks to the built-in thermometers.

Depending on the method of temperature control, the devices are also divided into the following types:

collecting information on the floor sensor;
collecting information on the air sensor;
combined – collecting information from various sensors.

Devices that collect information on air temperature sensors are the most common. It is these thermoregulators that are installed on heating radiators and used for boilers and convectors.

Devices that collect information on floor sensors have a rather limited range of capabilities and are used, as a rule, in rooms with a floor heating system.

Thermoregulators with a remote air temperature sensor can also be distinguished as a separate type. In this case, the information received by the control unit is more reliable, since the air temperature data was obtained at a considerable distance from the heating device. The thermal relay with a remote sensor is mounted on the wall and connected to the general wiring.

Thermoregulators with an air temperature sensor for an incubator are also arranged according to a similar principle. The thermostat is connected to the mains, the cord with the sensor is lowered into the incubator. On the outside of the thermostat there is a socket where you need to insert the power cord of the incubator. Using the information on the display, you will be able to control and, if necessary, change the temperature inside.

Useful advice! If your knowledge in this area is not enough, and you cannot independently choose a suitable thermostat for an infrared heater, contact specialists for help. This will help you avoid unnecessary hassle and expenses.

Electronic sensors for measuring air temperature

Electronic sensors are becoming increasingly popular these days. Such modern thermostats do not have moving parts designed to measure changes in air temperature. For this purpose, they use semiconductor parts.

The current acts as a power supply for such devices, so they are usually installed in an outlet or on a din rail. Batteries can also be used as power. The voltage required for the operation of the electronic sensor is 24 volts.

A modern thermostat with a built-in sensor is controlled from a mobile phone

Almost all electronic models of thermoregulators have a monitor that displays the last set temperature settings, as well as the current time and date. Modern models of thermostats are equipped with the function of adjusting the operation of the device in the day / night mode, weekdays / weekends and so on. Of course, the presence of all these functions significantly affects the price of the thermostat for the radiator, so before buying it is worth thinking carefully about how necessary all these functions are for you.

The monitor of the thermostat displays data from air sensors collected from different rooms

Despite the higher cost of electronic temperature controllers with an air temperature sensor, they have a number of advantages over mechanical ones:

they are much easier to install yourself;
they have a much larger temperature range, so that their use is permissible not only as a room thermostat for a gas boiler, but also in basements or garages, where the air temperature can drop to 0 degrees.

The multi-zone heating system with radiators and underfloor heating is controlled by a thermostat

You can buy a thermostat with an air temperature sensor in branded branches of companies manufacturing climate technology. It is better to give preference to the same manufacturer that appears on your heating boiler. In this case, you can easily connect the thermostat to the entire heating system.

If you know at least a little about the device of electrical engineering, you can save a lot by assembling a thermostat with an air temperature sensor with your own hands. To do this, you will need to purchase all the necessary components, including a microcontroller and a digital display.

It is better to buy a boiler and a thermostat from the same manufacturer

Also, there must be an element in the thermostat that measures the temperature and transmits data to the processing unit, which, in turn, converts or amplifies the received pulse and gives a command to the executive element – relay. A special circuit is used to assemble the thermostat. It is not difficult to make a thermostat with your own hands, but it is important to understand that assembly is only half the job, then you need to configure the device and connect it to the boiler. And this task is only possible for those who are well versed in electronics. If you have not done anything like this before, it is better to purchase a ready-made thermostat in order to avoid incorrect operation of the device and related dangerous situations.

Useful advice! All thermoregulators for infrared heaters allow you to connect several devices at the same time, but it is important to know that their total power should not exceed 3-3.5 kW. Otherwise, it is necessary to include a magnetic starter in the circuit, which will distribute the load.

Summing up, we can say that the purchase and installation of a thermostat for a heating or heating system is one of the most profitable investments imaginable. After all, the thermostat not only makes your life easier by providing a comfortable temperature in the room, but also significantly saves your money on utility bills.
