Abstract
A thermostat having heat anticipation uses a temperature responsive bimetallic element for effecting a thermostat contact closure during a heating operation controlled by the thermostat with an electrical contact carried by terminal strip positioned adjacent to the bimetallic element and formed from a high resistance stainless steel material. The resistance of the terminal strip is enhanced by lengthening the current path into a convoluted path utilizing notched out areas of the terminal strip. The resistance heat generated in the terminal strip by the current flow therein during the heating operation provides the desired heat anticipation for the operation of the thermostat by the bimetallic element by increasing the temperature sensed by the element.
