ABSTRACT:
An auxiliary heating/cooling system controller is connected in series between the household thermostat and the furnace burner valve and compressor. The controller includes a timing control which is responsive to a preset time interval valve and the plenum temperature to cycle the furnace burner on and off in order to moderate the temperature of the furnace heat exchanger, thus improving furnace efficiency. Upon installation the controller is programmed with a digital valve corresponding to the delay between a call for heat from the household thermostat and the initiation of the furnace fan. This value is then used to set a timer in the controller which synchronizes the initiation of the duty cycle control of the burner to the start of the fan at the beginning of a heating cycle, and to control the cycle time of the burner. A plenum thermostat monitors the temperature of the air produced by the furnace and if the air exceeds a predetermined limit the OFF time of the burner is increased. The cooling system control provides for cycling the compressor on and off in accordance with a programmed digital valve. The fan is kept activated to circulate dry, cool air when the compressor is in the off time of its cycle.
