ABSTRACT:
An electronic two stage furnace controller may be used interchangeably, without modification thereof, with either a single or two stage thermostat to regulate the heating and cooling operation of a two stage heating/cooling furnace to which the controller is connected. The controller is operative to monitor the input it receives from the thermostat, automatically deduce whether the input is from a single stage thermostat or a two stage thermostat, and responsively regulate the operation of the furnace under a corresponding single stage thermostat heating or cooling mode, or a corresponding two stage thermostat heating or cooling mode.
