ABSTRACT:
A control system for heating and cooling devices is disclosed which increase the total running time for the heating and cooling devices as the ambient temperature sensed deviates from the set-point temperature. Five states of ON-time modulation of 2, 5, 10, 15 and 20 minutes are preferred in response to this deviation. Constant periods of OFF-time of 2 or 5 minutes occur after each period of ON-time. Within a small deviation of the ambient temperature around the set-point temperature no conditioning equipment is operated. Beyond a large deviation, the respective heating or cooling equipment is operated continuously. A manual override is disclosed, and the system is manually switched from a heating to a cooling mode. A fan control line switches on whenever a heating or cooling device is actuated and the control system can be used with a heat pump.
