ABSTRACT:
A control system for a heating appliance, such as a microwave oven, includes a display and electronic circuitry for controlling operation of the appliance and the display. One of the control operations involves the timing of an interval, such as a cooking interval. Another such operation involves the selection of a power level. The display and a memory associated with the circuitry include predetermined dedicated time intervals and/or power level values depicted thereon and stored therein, respectively. Appropriate data-entry keys allow for the selection of these time and/or power values by slewing the display and thus the memory through the dedicated values. Separate keys may be provided for respectively incrementing and decrementing time and power.
