The working principle of thermostat is that according to the temperature change of working environment, physical deformation occurs inside the switch, which produces some special effects and a series of automatic control elements which can turn on or off. They are also called thermostat switch, temperature protector and temperature controller, for short, thermostat.

The temperature is transmitted to the temperature controller through the temperature protector, and the temperature controller sends out switching commands to control the operation of the equipment to achieve the desired temperature and energy-saving effect. Its application scope is very wide. According to different types of temperature controllers, they are applied in many products such as household appliances, motors, refrigeration or heating.

There are two kinds of control methods: one is controlled by the temperature change of the cooled object, the other is controlled by the temperature difference change of the cooled object, and the other is controlled by the electronic temperature controller.

The types of temperature controllers are: liquid-rising temperature controllers, pressure temperature controllers, electronic temperature controllers, digital temperature controllers.

The commonly used intelligent thermostat controls the characteristics of household heating equipment.

1. Convenience: It is necessary for working families to adjust the wall-hanging stove automatically and in advance or delay every day without manual operation.

2. Comfort: Every morning, midnight and evening, the room temperature is adjusted automatically to avoid the embarrassment of waiting for the room to warm up after getting up in the morning and returning home from work.

3. Gas saving: changing the backward extensive water temperature control to advanced and accurate room temperature control, and running at fixed room temperature in different time periods on demand, without open day and night heating;

4. Rest assured: when the room temperature is too low, the wall-hanging stove can be started forcibly. Only a little gas is needed, so that the room can be safely protected against freezing.
