ON/OFF TIME RATIO
In grill cooking, convection cooking or dual cooking, the
grill heating elements or magnetron operate within a 48
second time base. The following table is the ON / OFF time
ratio at each power output of the grill heating element or
magnetron.

AUTOMATIC COOKING
Auto Cook functions automatically work out the correct
cooking mode and cooking time and/or cooking tempera-
ture. They will cook according to the special cooking
sequence.

ture. They will cook according to the special cooking

POWER OUTPUT REDUCTION
After the same cooking mode is carried out for more than
the basis cooking time, the power output is automatically
reduced by turning the control relays on and off intermit-
tently, as shown in the table below. This is to protect the
oven door against temperature rising.

FAN MOTOR OPERATION (in Grill, Convection
and Dual mode)
and Dual mode)
When oven is stopped during cooking, or after the cooking
is completed, the fan motor will operate if the oven cavity
temperature is above 120˚C, and the fan motor will stop if
the oven cavity temperature is below 105˚C.
is completed, the fan motor will operate if the oven cavity
temperature is above 120˚C, and the fan motor will stop if
the oven cavity temperature is below 105˚C.
CONVECTION MOTOR OPERATION
If the temperature of oven cavity is higher than 120˚C
after and when operated by 250˚C convection cooking,
250˚C dual convection cooking or 250˚C preheating, the
convection motor will operate for maximum 1 minute until
the oven cavity temperature drops below 105˚C.

ABSOLUTE HUMIDITY SENSOR (AH SENSOR)
COOKING CONDITION
COOKING CONDITION
When the AH sensor is used, the foods are cooked in
microwave cooking mode without figuring time, power
level or quantity. When the oven senses enough steam
from the food, it relays the information to its microproces-
sor which will calculate the remaining cooking time and
power level needed for best results.
When the food is cooked, water vapour is developed.
The sensor “senses” the vapour and its resistance in-
creases gradually. When the resistance reaches the value
set according to the menu, supplementary cooking is
started. The time of supplementary cooking is deter-
mined by experiment with each food category and input-
ted into the LSI.

An example of how sensor works:
1. Potatoes at room temperature. Vapour is emitted very
slowly.
2. Heat potatoes. Moisture and humidity is emitted rap-
idly. You can smell the aroma as it cooks. ;
3. Sensor detects moisture and humidity and calculates
cooking time and variable power.
