ABSTRACT:
An electronic thermostat with a mode selection switch for selective application of actuation signals to different output control terminals for connection with control of either cooling or heating apparatus in accordance with sensed temperature. Circuitry is provided to derive A.C. input power to a D.C. power supply from a selected one of the control terminals to eliminate the need for separate A.C. power leads. The mode selection switch also selectively applies cool and heat trigger signals to a shared actuation signal generator. Time delay circuits for delaying the time between generation of a trigger signal and resultant application of an actuation signal share a common circuit element through means of the mode selection switch.
