Heat sink temperature
An NTC sensor which protects the electronic components against overloading is arranged on the heat
sink. The following action is taken if the heat sink temperature is to high:
♦
At a heat sink temperature > 76 °C any active booster function is ended.
The booster LED goes off.
♦
At a heat sink temperature > 85 °C the power supplied is limited to max. 66% (cooking level 8).
If the cooking zones are used at level 9, the power reduction to 66% is indicated in the correspond-
ing actuator displays by the flashing of the values 9 and 8.
♦
If the heat sink temperature rises to over 90 °C in spite of the preceding power reduction, all cooking
zones are switched off.
The corresponding actuator displays indicate this by the flashing of "dark" and “0“.
♦
When the heat sink temperature falls below 85 °C again, the cooking zones are switched on again.
If the set power is greater than 66% (cooking level = 9), this takes place at reduced power.
Then the value between 9 and 8 flashes in the actuator displays.
♦
As soon as the heat sink temperature is < 80°C, the cooking zones work at the set cooking level 9
again with the desired power.
The actuator displays stop flashing and indicate the cooking level set.
The parameters of the temperature values are stored in the EEPROM.
