The issue of heating your home has long become relevant. Now many users are switching to autonomous central heating: electric and gas. Heating by electricity can be carried out using a boiler with a heating system, in the form of interconnected batteries with a coolant, using convectors and using a warm floor.

Electric heating system
This type of heating has several advantages:
-
the ability to independently select the desired temperature regime; - the likelihood of cost savings in the presence of a multi-tariff electricity meter;
- no need to wait for the start or end of the heating season. The owner of the "autonomous" itself makes a decision on turning on or off his heating;
- This type of heating does not have a harmful effect on the environment in the form of combustion products, as in gas heating.
To create a comfortable microclimate, it is necessary to regulate the heat generated by the equipment. For this, thermostats with a thermostat are used. Modern electric heating devices have a wide variety: boilers, convectors, underfloor heating. Many of the heating boilers have a built-in programmer (daily, weekly) capable of adjusting the room temperature according to a program set by the user. But often a situation arises when a budget heater is purchased, the functions of which do not include temperature control. Basically the built-in regulator only controls the temperature of the media. Thermoregulators are used to control the temperature of the room.
Types of thermostats
According to the constructive solution, 2 main categories can be distinguished:
- mechanical thermostats;
- electronic regulators.
Mechanical instrument
An example of a mechanical regulator is a capillary regulator. It works on the principle of liquid expansion in a capillary when heated. When the set temperature is reached, the membrane acts on the contact, and it breaks the power supply circuit of the heater, disconnecting it from the network.
In order to understand how to connect a thermostat, you need to understand how the boiler circuit works. You can connect a thermostat not only to electrical equipment. Modern gas boilers can also be controlled by such a device. Let's consider the simplest example of boiler operation. The signal from the media temperature sensor goes to the heater control relay. When the set temperature is reached carrier relay is disconnected. At the same time, the room temperature is not controlled in any way. When a thermostat is connected to the circuit, control over the operation of the heater is assigned to the thermostat, which monitors the set temperature in the room.
It is not difficult to figure out how to connect the thermostat. It is enough to look at the passport of the heater. As a rule, a jumper is installed in the device circuit by the manufacturer, instead of which the controller contacts must be connected.
Electronic regulator
This type of regulator is much more expensive than mechanical regulators and is much more convenient in terms of its functions. Such a device allows you to set and regulate the room temperature both during the day and in the week. Possibility of saving appears. For example, electricity is much cheaper at night than during the day. This can be used when programming temperature cycles. In the absence of the owners of the house, install cooler temperature.
Being away for several days, it is permissible to keep an empty apartment at a temperature below a comfortable one, and before the owners of the house appear, the thermostat will enter the increased mode set in the program temperature.
Among electronic devices, I would like to highlight two main types:
- wired thermostat;
- wireless device.
The wired thermostat connection diagram is the same with the connection of a mechanical device. Instead of a jumper, the device contacts are connected in the circuit. The regulator itself is carried out with the help of wires at some distance from the heat source and fixed in a convenient place. Thus, the control will be the temperature at the place of its fixation.
No wires are needed for a wireless device. Such a device consists of two parts:
- room thermostat (freely portable);
- receiving device.
The receiving device is installed directly near the heating device and is included in the circuit in the same way as a wired system. The room thermostat can be located anywhere in the room, where the air temperature will be controlled. You can put it on your bedside table and control the temperature freely. Communication between these two elements occurs through radio waves.
In the same way, underfloor heating control is available. To connect the thermostat to several convectors located in separate rooms, you will need to apply a different scheme:
- control of all convectors through one starter;
- control of each heater separately.
In the first case, you will need a starter. It will be controlled by one thermostat: all devices will turn on and off at the same time.
In the second case, thermostats will be needed in an amount equal to the number of heating devices. Each of them will control one convector. This option is much more expensive, since the cost of each regulator is far from small, it varies within the selected option according to the principle - the better, the more expensive.
