gas burners may distort the base of the pan,
causing it not to adhere correctly.

Safety devices

Pan sensor
Each cooking zone is equipped with a pan sensor
device. The hotplate only emits heat when a pan
with suitable measurements for the cooking zone is
placed on it. If the indicator light is flashing, it may
indicate:
• An incompatible pan
• A pan whose diameter is too small
• The pan has been removed from the hotplate.
Residual heat indicators
Each cooking zone is equipped with a residual heat
indicator. This indicator signals which cooking zones
are still at a high temperature. If the power display
shows , the cooking zone is still hot. It is
possible, for example, to keep a dish warm or melt
butter or chocolate. The display switches off when
the cooking zone has cooled sufficiently.
Overheating protection
If the electronic components overheat, the hob
automatically turns off and the
on the 4 displays, followed by a flashing number.
This message disappears and the hob may be used
again as soon as the hob temperature drops to a
suitable level.
Safety switch
The appliance has a safety switch which
automatically switches the cooking zones off after
they have been in operation for a certain amount of
time at a particular power level. When the safety
switch has been triggered, the display shows "0 0 0 0 0 ".
For example: the right rear hotplate is set to 5, while
the front left hotplate is set to 2; the former will turn
off after 4 hours of continuous operation, while the
latter will turn off after 6 hours.
