What is a Programmable Room Thermostat? A programmable room thermostat is both a programmer and a room thermostat. A programmer allows you to set “On” and “Off” periods to suit your own lifestyle. A room thermostat 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.
