Abstract
An apparatus for activating climate control systems in response to the entry and/or presence of person(s) in a dwelling. An interior sensor apparatus includes a motion or thermal energy detection unit which emits a signal in response to the presence of person(s) within a room. A door entry sensor emits a signal upon entry of person(s) into the dwelling. A climate control unit, such as an air conditioner, has a default temperature setting which is activated upon the expiration of a timing sequence maintained by a timing circuit. The timing circuit is reset upon detection of persons by the motion/thermal detection unit or the door entry sensor.
