In the front central area of the hob, the displays of the
touch control system indicate:
INDUCTION COOKING SYSTEM
When your induction hob is switched On and a cooking zone has been selected, the
electronic circuits produce induced currents that instantaneously heat the bottom of the
pan which then transfers this heat to the food. Cooking takes place with hardly any energy
loss between the induction hob and the food.
Your induction hob operates only if a correct pan with the right features is placed on a
cooking zone. Please refer to COOKWARE FOR INDUCTION COOKING.
If the pan detection symbol appears on the display, your pan is not suitable and your
induction hob will not operate. After 10 minutes without detecting any pan, the cooking
zone switches Off automatically.

REMAINING HEAT INDICATORS
When the temperature of a cooking zone is still hot, the relevant remaining heat
indicator lights up on the display to alert you of the hot surface.
Avoid touching the hob surface over the cooking area. Please pay special attention to
children.
When the is lit on the display, it is still possible to start cooking again; just operate the
cooking zone as indicated in the chapter
POWER IGNITION AND ADJUSTMENT OF A
COOKING ZONE
.
COOKWARE FOR INDUCTION COOKING
The induction cooking system OPERATES ONLY if using correct cookware suitable for
induction cooking.
The bottom of the pan has to be ferromagnetic to generate the electromagnetic eld
necessary for the heating process (meaning a magnet has to stick to the bottom of the
pan).
Pans made from the following materials are not suitable:
• glass, wood, porcelain, ceramic, stoneware;
• pure stainless steel, aluminium or copper without magnetic bottom.
To check if a pan is suitable or not:
• test the bottom of the pan with a magnet: if the magnet sticks, the pan is suitable.
• if a magnet is not available pour a small amount of water inside the pan and place the
pan on a cooking zone. Switch on the cooking zone: if the symbol (pan detection)
appears on the cooking zone display (instead of the power level), the pan is not
suitable.
Important note: the cooking zones will not operate if the pan diameter is too small (
pan detection symbol will appear on the cooking zone display). To correctly use the cooking
zones follow the indications given in the following table.
Induction cooking zone Minimum pan diameter recommended
(referred to the bottom of the pan)
Cooking zone Ø 160 mm 110 mm
Cooking zone Ø 200 mm 145 mm
Pay attention: The pan shall always be centred over the middle of the cooking zone. It
is possible to use oversized pans but the bottom of the pan cannot touch other cooking
zones.
Always use pans with thick, completely at bottom.
Do not use pans with concave or convex bottom; these could cause overheating of the
cooking zone.
Note: Some types of pans could cause noise when used on an induction cooking zone.
The noise does not mean any failure on the appliance and does not inuence the cooking
operation.

MAXIMUM USABLE POWER FOR THE
COOKING ZONES
The left and right cooking zones are controlled
by two separate power boards.
Where a power board manages two zones
(front/rear LH zones; front/rear RH zones) the
maximum total power per each power board is
3700 W.
Should the cooking zones of one power board
require more than 3700 W, the last selected
power level has priority and the power of the
other cooking zone is automatically reduced to
the remaining power available.
If this occurs, the cooking zone will display
a ashing gure for about 3 seconds before
automatically displaying the new power level.
This means for example that:
• When setting a “Booster” programme for the second zone, the setting for the other
zone could be reduced to the remaining power available.
• When setting a “Booster” programme for a zone and then another setting on the
second zone, if the total power exceed 3700 W the “Booster” programme is deleted
and the power reduced to the maximum power available.
THERMAL PROTECTIONS
The induction hob is tted with safety devices to protect the electronic system and to protect
each cooking zone from overheating.
In case of overheating, one of the following automatic functions could be started by the
electronic system:
• “Booster” program deleted and power reduced.
• One or more cooking zone switched Off.
• Cooling fan motor of the induction unit switched On.

ADVICE FOR SAFE USE OF THE HOB
• Before switching on make sure that
you have the correct cooking zone for
the hotplate chosen. It is advisable
to put the pan on the hotplate before
switching on and to take it away after
switching off.
• Use cookware with at and even
bottoms. Uneven bottoms can scratch
the glass ceramic surfaces. Be careful
that the bottom is clean and dry.
• Do not leave wet or damp lids on the
hob.
• The glass-ceramic surface and pans
must be clean. Carefully eliminate any
food remains (especially containing
sugar), dirt etc. with the aid of a
cleansing agent.
• Make sure that the handles of
cookware do not stick out over the
edge of the hob, to avoid them being
knocked over by accident. This also
makesitmoredifcultforchildren
to reach the cooking vessels.
• Do not lean over the cooking zones
when they are switched on.
• Do not drop heavy or sharp objects
on the glass ceramic cooktop. If the
surface is broken or damaged
unplug the cooktop and contact the
after-sales service.
• Do not put aluminium foil or plastic
objects on the cooking zones when
they are hot.
