Convection Cooking Duty Cycles
7.5. Combination Cooking
Combination Cooking is achieved by operating the Microwave and Heater modes together
during one cooking cycle. There are three possible combination modes:
1. Convection and Microwave
2. Grill and Microwave
3. Convection, Grill and Microwave
The Digital Programmer Circuit operates the power relays as shown in the figures below. / /
When the oven temperature reaches the predetermined temperature, the Digtal Progammer
Circuit stops supplying power to the relay RY5 resulting in the convection heater turning off.
During this time, the Digital Programmer Circuit continues to operate relay (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 and covection elements are operated alternatively whilst the oven temperature is above
the selected level. / /
