  • Electronic control and method for increasing efficiency of heating and cooling systems
    Patent number: 4682473
    Abstract: A method of increasing the efficiency of a cooling system by measuring the temperature differential across the cool air inlet and outlet which occurs during normal operation of the cooling system to reduce the room temperature from its turn-on point to its turn-off point. The temperature differential so determined is then utilized to cycle the cooling system to increase efficiency thereof.

  • Electronic control and method for increasing efficiency of heating
    Patent number: 4607787
    Abstract: A method of increasing the efficiency of a hot air furnace by measuring the temperature differential across the heated air inlet and outlet plenums which occurs during normal operation of the furnace to raise the room temperature from its turn on point to its turn off point. The plenum temperature differential is then used to time cycle the burner.
