Thermoregulator

1. Thermoregulator – valves automatic control of heating or cooling equipment.
2. Thermoregulator is a device (such as a thermostat) for the regulation of temperature.

Thermoregulator is a regulator for automatically regulating temperature by starting or stopping the supply of heat. Thermoregulator includes a sensor that transmits the current value of the temperature to the measuring device, where it is compared with the set value; if the measured and set temperatures differ, the thermoregulator emits a mismatch signal, and the controller changes the flow of heating or cooling agent to the heating system.
