TOUCH CONTROL SAFETY FUNCTIONS
The following safety functions are available to avoid unintended operations of the cooktop control:
Cooking Zone Safety Cut Off
To prevent the appliance from unwanted, random button operation, a sensor monitoring is included.
In the case of one or more buttons being pressed longer than 12 seconds, the sensor monitoring routine
indicates acoustically that an “error” (pot or other object placed on the button, sensor failure, etc.) has
occurred and switches off the appliance.
Note: a spillage of liquids onto the control panel can also cause this safety function to engage, or even turn
the unit off.
If residual heat is present, it will be displayed in all other Power Level Displays with a red “H”.
Over Temperature Switch Off
Because the controls are very close to the cooking zones at the front of the cooktop, it is possible that a pot
can be placed half on the control and not be sensed by the sensor safety cut off (not covering a sensor). This
can cause the cooktop to heat up to a very high temperature, which makes the glass and the buttons
untouchable without burning a finger.
A temperature sensor installed in the touch control unit will help to prevent damage to the control unit by
turning the appliance off when overheating occurs.
Operating Time Limitation
The cooktop control has a limitation on the operating time. If the power level for a cooking zone has not been
changed for a certain time, then the cooking zone will turn off automatically (a “0“ is displayed for 10 seconds,
then the residual heat sign “H” is displayed). The limit of the operating time depends on the selected power
level. After an automatic turn off of a cooking zone (as described above) the cooking zone is operable again
and the maximum operating time for this power level is re-applied.
Residual Heat Functions
After all cooking processes there is some heat stored in the vitroceramic glass called residual heat. The
control can calculate roughly how hot the glass is in the worst case. If the calculated temperature is higher
than + 60 ° C, then this will be indicated in the corresponding Power Level Display after the cooking zone
control has turned off with a red “H”. The residual heat display is shown as long as the calculated cooking
zone temperature is > + 60 ° C.
The display of the residual heat has the lowest priority and is overwritten by every other display value, during
safety turn offs and the display of an error code.
When the supply voltage is re-applied to the cooktop after an interruption to the supply voltage, the residual
heat display does not come back on.
