Abstract
A temperature control system for an electronically-controlled thermal cooking oven having a single oven temperature sensor, which system facilitates varying the calibration set point in the field for normal cooking modes, without affecting the self-cleaning temperature calibration which is factory preset. A sensor-developed analog voltage is employed to control self cleaning temperature in the oven, with the oven temperature during normal cooking modes, such as bake and broil, controlled by the same voltage modified by an independently developed offset value or signal. The required summing of the sensor voltage and the offset voltage preferably is done by means of a suitably-programmed microprocessor-based control system. With this arrangement, the offset can be changed to vary the set point for normal cooking modes without affecting the self-cleaning temperature which is detected solely by the sensor, and cannot be readily varied by field adjustment. Further, the field temperature calibration procedure is simplified due to a predictable discrete adjustment which eliminates cumbersome trial and error procedures.
