Operation GB
Operation The hob
The hob is equipped with an induction cooking mode. An induc-
tion coil underneath the glass ceramic hob generates an electro-
magnetic alternating field which penetrates the glass ceramic
and induces the heat-generating current in the pot base.
With an induction cooking zone the heat is no longer transferred
from a heating element through the cooking pot into the food
being cooked; instead the necessary heat is generated directly in
the container by means of induction currents.
Advantages of the induction hob
– Energy-saving cooking through the direct transfer of energy to
the pot (suitable pots/pans made of magnetisable material are
required).
– Increased safety as the energy is only transferred when a pot
is placed on the hob.
– Highly effective energy transfer between an induction cooking
zone and the base of a pot.
– Rapid heat-up.
– The risk of burns is low as the cooking area is only heated
through the pan base; food which boils over does not stick to
the surface.
– Rapid, sensitive control of the energy supply.
Pan recognition
If a cooking zone is switched on and there is no pan on the zone
or if the pan is too small, there will be no transmission of power. A
blinking in the cooking level display points this out.
If a suitable pot or pan is placed on the cooking zone, the power
setting will switch on and the power setting display will light up.
The power supply will be cut off when the pan is removed and the
power setting display will indicate a blinking .
If the pots and pans placed on the cooking zone are of smaller
dimension, and the pan recognition still switches on, less power
will be supplied.
Pan recognition limits
For some of the models the minimum diameter of the base of a
pot is indicated as an inner circle on the cooking zones.
Important: The minimum diameter required to activate the pan
recognition device may vary according to the type of pot or pan
used!
Operation time limit
The induction hob has an automatic time limit function.
The duration of continuous use of each cooking zone depends on
the cooking level selected (see chart).
This requires that the setting of a respective cooking zone is not
adjusted during use.
If the operation time limit has been activated, the cooking zone
will switch off, a short signal will sound and an H will appear in
the display.
The automatic switch-off function overrules the operation time
limit, i.e. the cooking zone is only switched off when the period of
time of the automatic switch-off device has expired (e.g. auto-
matic switch-off after 99 minutes and cooking level 9 is possible).
Other functions
If two or more sensor keys are pressed at the same time (e.g.
when a pan is mistakenly put onto a sensor key) no function will
be activated.
The symbol will blink and a time-limited continuous signal will
sound. After a few seconds the appliance will switch off. Please
remove the item located in front of the sensor keys.
To delete the symbol press the same key or switch the hob off
and on.
Protection against overheating
(induction)
If the hob is used at full power for a longer period, it will not be
possible to cool down the electronics system as required at a
high room temperature.
In order to ensure that no excessive temperatures occur in the
electronics system the power of the cooking zones may be
reduced automatically.
Should E2 be displayed frequently during normal use of the hob
and at normal room temperature, it is likely that cooling is not suf-
ficient.
The reason may be that there are no openings for cooling pur-
poses in the kitchen units. It may be necessary to check the
installation of the hob (see the section on Ventilation).
