What is a room thermostat?
... an explanation for householders. A room thermostat simply switches 
the heating system on and off  as necessary. It works by sensing the 
air temperature, switching on the heating when the air temperature 
falls below the thermostat setting, and switching it off  once this 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 boiler and 
radiators.
Neither does the setting aff ect how quickly the room cools down. 
Turning a room thermostat to a lower setting will result in the room 
being controlled at a lower  temperature, and saves energy.
