Button monitoring is included to prevent the
appliance from unwanted button operation.
In cases where one or more buttons are
pressed for longer than 12 seconds, the
buzzer will sound for ten minutes to indicate
an incorrect operation. For example, an
object may be placed on a button, or there
could be a sensor failure and so on.
The safety switch-off will cause the hob to
go into S-mode and all heater displays will
flash “
F ”. If there is no incorrect operation
present, both the visual and audible signals
will disappear.
If residual heat is present, “
H ” will be
displayed on all other heater displays.
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
therefore heating up the hob to a very high
temperature. This makes the glass and the
buttons dangerous to touch.
To prevent the hob control unit from
damage, the controls constantly monitor the
temperature and switch off if overheating
occurs.
This will be indicated by the letter “
t ” in
the heater display until the temperature
decreases.
Once the temperature has dropped, the
“
t ” in the heater display will disappear and
the hob control unit will revert 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 switch off automatically.
A “
0 ” will be displayed for 10 seconds,
however there may be some residual heat
present. The limit of the operating time
depends on the selected heat setting.
After a heater automatically switches off, as
described above, the heater can be used
and the maximum operating time for this
heat setting is applied.
Residual Heat Functions
After all cooking processes, some heat
will be stored in the vitroceramic glass
called residual heat. The appliance can
calculate roughly how hot this glass is. If
the calculated temperature is higher than
+ 60 ° C, then this will be indicated in the
corresponding heater display for as long as
the calculated temperature remains above
+ 60 ° C, even after the appliance has been
switched off.
The residual heat indicator has the lowest
priority and is overwritten by every other
display value, including during safety
switch-off and the displaying of an error
code. When voltage is supplied to the hob
after a power interruption, the residual heat
display indicator will flash. If a heater had a
residual heat of greater than + 60 °C before
the power interruption occurred, the display
will flash while the residual heat remains
or until the heater is selected for another
cooking operation.
Hints and Tips
Important: When ceramic heaters are
operated in higher heat settings, the
heated areas may be seen switching
on and off. This is due to a safety device,
which prevents the glass from overheating.
This is normal at high temperatures,
causing no damage to the hob and little
delay in cooking times.
WARNING:
•
Never operate the hob without
pans on the cooking zone.
•
Only use flat pans with a sufficiently
thick base.
•
Make sure the bottom of the pan is dry
before placing it on the hob.
•
While the cooking zone is in operation,
it is important to ensure that the pan is
centred correctly above the zone.
•
In order to conserve energy, never use
