ABSTRACT:
In a forced air heating and cooling system including a blower fan for circulating air in an air ambient use-space, a timer circuit and a power output control circuit for augmenting control and for regulating operation of the blower fan. The timer and associated circuitry functions to activate the blower fan for finite limited periods of operation at each end of each heating and cooling cycle and at time-spaced intervals when neither heating nor cooling is called for in the controlled use-space. The timer device and supporting control circuitry are simply and readily incorporated into the conditioning system with a minimum of physical disruption of disturbance of leads and connections. Heating and cooling efficiencies are enhanced, comfort level is elevated, and objectionable temperature fluctuations are smoothed.
