Digital Room Thermostat

A digital room thermostat simply switches the heating system on and off as necessary. It works by sensing the air temperature and switching on the heating when it falls below the thermostat setting. The heating will then switch off once the set temperature has been reached. Turning a room thermostat to a higher setting will not make the room heat up any faster. How quickly the room heats up depends on the design of the heating system, for example, the size of the boiler and the radiators.
