ELECTRIC INDUCTION COOKING
SELECTED MODELS ONLY
SYSTEM TEMPERATURE CONTROL - INDUCTION
_______________________________________________________________________________________________________________________
•
Sensors situated inside the top constantly measures the temperature of the generator`s electronic circuits. In the event
of these circuits overheating the system reacts as follows:
•
When the first temperature is exceeded the system automatically switches off the booster. If activated, this initiates a
flashing `P` on the respective display showing that the booster cannot be responded to at the moment. When exceeding
a second medium temperature limit, the induction system reduces the power outlet to avoid any temperature increase.
When the temperature of the cooking zone exceeds a third temperature limit, the cooking zone is cut off automatically
from the induction system. The corresponding display indicates a flashing error code E2, possibly alternating with `H`.
The overheating of the circuits definitely indicates an anomaly, and means that the cook top has not been installed
properly or the openings for air circulation are not large enough.
