ABSTRACT:
This invention is an apparatus for controlling food temperatures in a food warming cabinet having at least one food holding zone. The apparatus includes a first sensor for sensing a temperature representative of the temperature of the food, a heater, a second sensor for sensing a temperature representative of an operating condition of the apparatus, and a control circuit connected to receive sensed input signals from the first and second sensors, and being constructed and arranged for controlling the operation of the heater in response to the sensed input signals and for selecting a set point value forming an ideal temperature condition for the food.
