Convection Cooking
1. The digital programmer circuit operates the power relays
RY3,RY5 and RY6 in the sequence as shown in the fig-
ure below.
2. When the oven reaches a predetermined temperature the
digital programmer circuit stops supplying power to relay
RY5, resulting in the convection heater turning off.
3. When the temperature drops below the predetermined
temperature, the digital programmer circuit supplies
power to power relay RY5 resulting in the convection
heater turning on.
Note: After the convection process, if the oven tempera-
ture is higher than the predetermined temperature, the
fan motor rotates to cool the electronic components and
the oven.
