4. Operation
4.1 The hob
The hob is equipped with an induction cooking mode. An
induction coil underneath the glass ceramic hob generates
an electromagnetic alternating fi eld 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 magneti-
sable material are required).
• Increased safety as the energy is only transferred when
a pot is placed on the hob.
• Highly eff ective 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 he-
ated through the pan base; food which boils over does
not stick to the surface.
• Rapid, sensitive control of the energy supply.
4.2 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 transmis-
sion of power. The symbol in the power setting 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 indicator
will light up. The power supply will be cut off when the pan
is removed and the power setting display will indicate .
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.

The base of pots and pans must be of a certain diameter;
if it is not, the induction heat will not be switched on. Al-
ways place pots and pans in the middle of a cooking zone
in order to achieve the best effi ciency.
Important: The minimum diameter required to activate the
pan recognition device may vary according to the type of
pot or pan used!
4.3 Operation time limit
The induction hob has an automatic time limit function.
The duration of continuous use of each cooking zone de-
pends 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. automatic switch-off after 99 minutes and
cooking level 9 is possible).

4.4 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.
4.5 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 requi-
red 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 fre-
quently during normal use of the hob and at normal room
temperature, it is likely that cooling is not suffi cient.
This may occur if kitchen units have no openings. The
installation may have to be checked (see the section on
Ventilation).
