FR2558279

A device to compensate for the thermic effects of an external source on a sensitive element in a system for automatically controlling the temperature reached by foods in heated vessels. The device includes a conventional range and a potentiometer for controlling a gas or electric heating element. Two heat sensitive elements are employed, one sensing pan temperature, and the other sensing ambient temperature. Electric circuitry automatically adjusts the heating element to reduce the heat output as the ambient temperature rises, so that a more constant vessel temperature is achieved.
