Touch Control Safety Functions
The following safety functions are available
to avoid unintended operations
Sensor Safety Cut Off
To prevent the appliance from unwanted
button operation, button monitoring is
included. In cases where one or more
buttons are pressed for longer than 12
seconds, there is an audible noise to
indicate an incorrect operation (pot or other
object placed on the button, sensor failure,
etc.) and the appliance switches off.
The safety turn off causes the hob to go
into S-Mode. An "F" will flash in all heater
displays.

. As
If residual heat is present, it will be
displayed in all other heater displays.
The hob control will then go into S-Mode.
At the same time a buzzer sounds. After 10
minutes the buzzer will stop.
If there is no erroneous operation present,
both the visual and the audible signals will
disapear.
Over Temperature Switch Off
Due to the controls being very close to the
heater in the middle of the front of the hob,
it can occur that an incorrectly placed pot is
not sensed by the sensor safety cut off (not
covering a button) and heats up the hob to
a very high temperature, which makes the
glass and the buttons dangerous to touch.
To prevent the hob control unit from
damage, the controls constantly monitor the
temperature and switches off if overheating
occurs.
This is indicated with the letter "t" in
the heater display until the temperature
decreases.
Once the temperature has dropped, the "t"
in the heater display will be cleared and the
hob control unit reverts back into S-Mode.
This means that the user can reactivate the
appliance by pressing
Operating Time Limitations
The hob control unit has a limitation on
the operating time. If the heat setting for a
heater has not been changed for a certain
time, the heater will turn off automatically
(for 10 sec a "0" is displayed. Some
residual heat may be present). The limit of
the operating time depends on the selected
