Abstract
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.

Claim 1
Independent Claim
121 words
An air conditioning/heat control system for a dwelling comprising: means connected to an entrance to a dwelling for detecting the entrance of a person to said dwelling, said means electrically connected to a main control panel, said control panel having temperature detecting means for determining the ambient temperature of said dwelling, and control means for setting a default temperature setting, and means for setting a temperature in said dwelling, and a countdown timer, whereby when said means connected to an entrance to a dwelling detects the entrance of a person to said dwelling, the main control panel deactivates said default setting and activates said countdown timer and allows a person to control the means for setting a temperature in said dwelling.
Claim 2
Dependent Claim
121 words
An air conditioning/heat control system for a dwelling comprising: means connected to an entrance to a dwelling for detecting the entrance of a person to said dwelling, said means electrically connected to a main control panel, said control panel having temperature detecting means for determining the ambient temperature of said dwelling, and control means for setting a default temperature setting, and means for setting a temperature in said dwelling, and a countdown timer, whereby when said means connected to an entrance to a dwelling detects the entrance of a person to said dwelling, the main control panel deactivates said default setting and activates said countdown timer and allows a person to control the means for setting a temperature in said dwelling.
Claim 3
Dependent Claim
86 words
The air conditioning/heat control system for a dwelling as claimed in claim 1, wherein said main control panel also contains a motion/heat sensor means for detecting the presence of a person in said dwelling, said motion/heat sensor means deactivates said countdown timer when the presence of a person is not detected for a predetermined time, when said motion/heat sensor means activates said countdown timer, said countdown timer runs for a predetermined period of time and then activates said control means for setting a default temperature setting.
Claim 4
Dependent Claim
