Abstract
Abstract A heat loss time throttling circuit is disclosed in which an outdoor heat loss detector subordinates the indoor thermostat by using a condition sensitive housing to encapsulate the outdoor heat loss detector and a heating element which actuates the outdoor loss detector in short time durations through an electrical source. The heating element is placed in series with the source and the indoor thermostat may be connected between the source and the heating element or between the control device and the heating element. An alternate form is disclosed for use with a cooling mechanism, both forms being relatively inexpensive in their construction.
