2.2 Cooking hob
* Power levels are approximate and can vary according to the pan used or the settings made.
Advantages of induction cooking • Energy saving thanks to the direct
transmission of energy to the pan
(suitable magnetisable cookware is
required) compared to traditional
electric cooking.
• Improved safety as the energy is only
transmitted to the pan placed on the hob.
• High level of energy transmitted from the
induction cooking zone to the base of
the pan.
• Rapid heating speed.
• Reduced danger of burns as the cooking
surface is only heated under the base of
the pan; foods which overflow do not
stick.

The hob is equipped with an
induction generator for each
cooking zone. Each generator
located under the glass ceramic
cooking surface creates an
electromagnetic field which
induces a thermal current in the
base of the pan. This means the
heat is no longer transmitted from
the hob to the pan but created
directly inside the pan by the
inductive current.

EN
3.2 Using the hob
All the appliance’s control and monitoring
devices are located together on the front
panel. The relevant cooking zone is
indicated next to each knob.
Just turn the knob clockwise to the required
power setting.
Cookware suitable for use in induction
cooking
Cookware used on the induction cooking
surface must be made of metal, with
magnetic properties and a sufficiently large
base.
Suitable cookware:
• Enamelled steel cookware with thick
bases.
• Cast iron cookware with an enamelled
base.
• Cookware in multilayer stainless steel,
ferritic stainless steel and aluminium with
a special base.
Unsuitable cookware:
• Copper, stainless steel, aluminium,
fireproof glass, wood, ceramic and
terracotta cookware.
To see whether the pan is suitable, bring a
magnet close to the bottom: if it is attracted,
the pan is suitable for induction cooking. If
you do not have a magnet, you can put a
small amount of water in the pan, place it
on a cooking zone and start the cooking
zone. If the symbol appears on the
display, it means the pan is not suitable.
On first connection to the electrical
mains, an automatic check will be
carried out that will switch on all
indicator lights for a few seconds.
After use, turn off the hot plates
used by returning the appropriate
knob to the Oposition. Never rely
solely on the cookware detector.
Use only cookware with a
perfectly flat bottom which is
suitable for induction hot plates.
Using cookware with an irregular
bottom could jeopardise the
efficiency of the heating system
and prevent cookware from being
detected on the cooking zone.

Use
62
Cookware recognition
When there is no saucepan on a cooking
zone or if the saucepan is too small, no
energy will be transmitted and the symbol
will appear on the display.
If there is a suitable saucepan on the
cooking zone, the recognition system
notices it and turns on the hob to the power
level set using the knob. Energy transmission
is also interrupted when the saucepan is
removed from the cooking zone (the
symbol will be shown on the display).
If the cookware recognition function is
activated in spite of the saucepan or frying
pan on the cooking zone being smaller
than the zone itself, only the necessary
energy will be transmitted.
Cookware recognition limits: The minimum
diameter of the pan base is indicated by the
cross on the cooking zone.
Pans with smaller diameters risk not being
detected and therefore not activating the
inductor.
Limiting the cooking duration
The hob has an automatic device which
limits the duration of use.
If the cooking zone settings are not
changed, the maximum duration of
operation for each zone depends on the
power level selected.
When the device for limiting the duration of
use is activated, the cooking zone turns off,
a short alert sounds and, if the zone is hot,
the symbol appears on the display.
Protection from overheating
If the hob is used on full power for a long
period, the electronics will have trouble
cooling down if the room temperature is high.
To avoid excessively high temperatures
forming in the electronics, the power to the
cooking zone is reduced automatically.

Advice on energy-saving
• The diameter of the base of the pan must
correspond to the diameter of the
cooking zone.
• When buying a pan, check whether the
diameter indicated is that of the base or
the top of the pan, as the top is almost
always larger than the base.
• When preparing dishes with long
cooking times, you can save time and
energy by using a pressure cooker,
which also makes it possible to preserve
the vitamins in the food.
• Make sure that the pressure cooker
contains enough liquid as, if there is not
enough and it overheats, this may cause
damage to both the pressure cooker and
the cooking zone.
• If possible, always cover saucepans with
a suitable lid.
• Choose a pan suitable for the quantity of
food to be cooked. A large, half-empty
saucepan leads to a waste of energy.
Power levels
The power in the cooking zone can be
adjusted to various levels. The table shows
the levels suitable for various types of
cooking.
* see booster function
Residual heat
If the cooking zone is still hot after being
switched off, the symbol will be
displayed on the display. The symbol clears
once the temperature drops below 60 °C.
Under certain circumstances, if the
hob and the oven are being used
at the same time, the maximum
power limit that can be used by the
electrical system might be
exceeded.

moment. The “maximum power” period will
automatically be modified.
Once the acceleration period is over the
power level will remain the same as the one
previously selected.
Keep warm
To activate the keep warm function:
• Turn the knob for the desired cooking
zone until the symbol appears on
the corresponding display.
Multizone function
To activate the Multizone function:
1. Turn the front left and rear left cooking
zone knobs anticlockwise at the same
time and hold them at the M-A position
until a short beep is emitted.
Each cooking zone is equipped
with a heating accelerator that
allows the maximum power to be
delivered for a time that is
proportional to the selected
power.
If the power is reduced, by turning
the knob anti-clockwise, the
heating accelerator will
automatically be disabled.
The Keep warm function allows
you to keep cooked food hot.
This function can be used to:
operate two cooking zones (front
and rear) simultaneously when
using pans like fish kettles or
rectangular pans.
The cooking zones with the
Multizone function are the front left
and the rear left cooking zones.

Use

both the cooking zones that are in use.
To deactivate the Multizone function:
Put both knobs back to the 0position (off).
Booster function
• Turn the knob clockwise to the Pposition
for two seconds and then release.
The display shows the symbol. After 5
minutes, the Booster function will be
disabled automatically and cooking will
continue at power level 9.
Only for some zones: the Booster function
is always enabled and has to be disabled
manually using the corresponding knob.
Power control
The hob is fitted with a power control
module that optimises/limits consumption. If
the overall set power level exceeds the
maximum limit permitted, the electronic
circuit board will automatically manage the
power supplied by the hot plates.
The module tries to maintain the maximum
deliverable power levels. Levels set by the
automatic control will appear on the
display.
The flashing of a power level indicates that
it will be automatically limited to a new level
selected by the power control module.
This function automatically divides
the power equally between both
zones that are in use.
The booster function allows the
cooking zone to be activated at
maximum power for as long as 5
minutes. It can be used to bring a
large quantity of water to a boil
rapidly or to broil meat.
The Booster function has priority
over the heating accelerator
function.
Priority is given to the last zone set.
