Abstract: A self contained heating and cooling system is disclosed comprising a heat pump unit having a heat exchanger for heating and cooling air in a space, an auxiliary heating unit for heating air in the space, a support housing for the heat pump and auxiliary heating units, a cycling thermostat for governing operation of the heat pump and auxiliary heating units to enable establishment of a predetermined space air temperature, and a changeover thermostat. The changeover thermostat includes switch having first and second conditions wherein operation of the auxiliary heating means is enabled and disabled, respectively, a control switch operator for operating the control switch to its first condition in response to sensed atmospheric air temperatures below a predetermined temperature and a second control switch operator comprising a mechanism supported by the housing at a location accessible to a system user and manually actuable to effect operation of the control switch to its first condition regardless of sensed atmospheric air temperature levels.
