Control Programming
The electronic temperature control is pre-set at the factory to maintain the temperature at the
bottom center of the pan cavity at 190° F +/- 5° F. This temperature is the result of many hours of
laboratory food testing. There are no operator temperature adjustments that can be made.
Because the electronic control uses a platinum type RTD sensor, routine calibration is not
required.
