Abstract
Abstract An electronic means to cyclically control the heat or air conditioning source in an environmental temperature control system so that the heat exchange surfaces are maintained within a predetermined range to maximize heat exchange efficiency and minimize total operating time of the heat or cooling source. The apparatus incorporates a temperature responsive transducer which provides a voltage level that is compared to an analog representation of a controllable, periodic output of a digital counter to produce a signal for selectively energizing the heat or cooling source of the environmental temperature control system for a time period proportional to heat demand but limited to relatively short durations of time so as to minimize or limit the temperature of the heat exchange surface during temperature modification demand periods.
