ABSTRACT:
A delayed response air conditioning/heating control system provides a detector which responds to a door or window left open, after a predetermined period of time, and which automatically resets to start time (maximum) if the door or window is closed prior to time of response; otherwise it disables the air conditioning heating system. The system has a wired, or anternatively a wireless, sensor with built-in delay and reset, and a receiver or detector with latching relay and manual relay reset control. If the air conditioning/heating system was operating at the time of disablement, a flashing light indicates this.
