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.
