ABSTRACT:
A thermostat for controlling heating apparatus is converted to a thermostat for controlling heating and cooling apparatus by the addition of a subbase. The heating thermostat has a double switch attached to a bimetal and a heating anticipation heater whereby heating apparatus is controlled when connected to the terminals of the thermostat. When it is desired to use the thermostat to control both heating and cooling apparatus, the thermostat is removed from the wall and a subbase is placed under the thermostat. The subbase has a cooling anticipation heater which is thermally connected to the bimetal. The subbase has terminals to connect the assembly of thermostat and subbase to the heating and cooling apparatus.
