Extended data:
The floor heating thermostat belongs to the switch for adjusting the computer temperature. There are two main types of floor heating thermostats, mechanical and electronic. There are electronic thermostats with liquid crystal (some electronic thermostats with liquid crystal have programmable function) and some without liquid crystal.
Mechanical thermostat, made of bimetal or metal diaphragm, can adjust the temperature of heating or cooling environment to a set temperature according to the principle of thermal expansion and cold contraction of an object (depending on whether a heater or a cooler is connected). Thermistor senses the ambient temperature electronically, and controls the operation or stop of the connected heater or cooler through relay.
There is a power switch in the middle of the temperature control switch. After pressing the power switch, turn on the temperature control switch to adjust the temperature. The mechanical floor heating thermostat can be adjusted left and right according to the above switch, and can rotate left and right according to the required temperature. Observe the thermostat carefully. When the light is on, it means that it works normally, and when the indicator light is off, it means that the thermostat stops working.
