7.5 Combination Cooking
TOP PREVIOUS NEXT
Combination cooking is achieved by operating the microwave and heater modes together during one
cooking cycle. There are three combination modes.
1. Combination (convection and microwave)
2. Combination (grill and microwave)
3. Combination (grill, convection and microwave)
The digital programmer circuit operators the power relays as shown in the figures below.
When the oven temperature reaches the predetermined temperature, the digital programmer circuit
stops supplying power to relay (RY5) resulting in the convection heater turning off. During this time
the digital programmer circuit continues to operaterelay (RY1) so that microwave activity continues
at the duty cycle selected. The inverter control signal level is also maintained. The microwave
activity continues to cycle until the entire cooking program is completed.
When the oven temperature drops below the selected temperature, the digital programmer circuit
operates power relay (RY5) switching on the heater elements.
In the case of grill combination the sequence applies with the digital programmer circuit switching
power relay (RY4) to control, the grill elements.
With convection, grill and micro power combination. The grill elements and convection elements are
operated alternatively whilst the oven temperature is above the selected level.
