Petropedia explains Thermostat

A thermostat is the main control unit for heating or cooling system. It can be constructed in many ways and can be used by different sensors to measure the temperature, however, the most commonly used sensors are thermistor and bimetallic strip. These sensors control heating or cooling apparatus. When the machine heats or cools the device runs at its full capacity until the set temperature is reached, then switches off. The increase in the difference between the thermostat setting and the desired temperature does not shorten the time to achieve the desired temperature.
