How Does a Thermostat Work?

Answer

A thermostat works to maintain a desired set temperature. It does this by initiating the heating source to turn on when the temperature falls below the set temperature. The heating system turns off when the thermostat senses that the temperature has met the desired setting on the unit. A thermostat works the same way when using a cooling system. It senses set temperature controls and sends the signal to the system that initiates power. There are many things whose temperature is controlled by a thermostat besides a building. cars, hot water in showers and sinks, and ovens all have thermostats to monitor their temperature.
