THE DEVICE

Power management function

This product has an electronically controlled power
management function. The Power management function
detects when the maximum power level of 3.7 kW/16
A is being delivered for the combined cooking elements
(right and left hand side phases), optimising power
distribution and avoiding any overloading of the induction
system.
To do this, the total power is monitored continuously, and
reduced when necessary. If it is not possible to supply
the total power required, a control element reduces by a
predefined amount the power in another cooking element
so that it is at a level immediately below its respective
power curve. This ensures that the current absorption of
16 A is not exceeded.
In this case the generator detects the last command
with the highest priority sent by the user interface and,
if necessary, reduces the previous settings activated for
another cooking element
The Power management function is first activated
when the presence of a pan is detected on the cooking
element.
Example:
If the power boost level (boost) (P) is selected in the
same phase (right and left hand phase) in a cooking area,
the other cooking area is automatically prevented from
simultaneously exceeding power level 5.
This aspect is variable according to the limits set for the
product (See paragraph "INSTALLER MENU").
How induction hobs work
Induction hobs work very differently from traditional
hobs or metal plate cookers. The induction coil located
under the vitreous ceramic surface quickly creates
a highly variable magnetic field, which heats the
magnetisable bottom of the pan directly.
The vitreous ceramic surface is only heated by the hot
pan. When the pan is removed from the cooking area,
the current supplied is cut off immediately.

Pan presence detection
Each of the cooking areas is equipped with a system
to detect the presence of a pan. The pan presence
detection system recognises pans with a magnetisable
base suitable for use with induction hobs.
If the pan is removed during operation, or if an
unsuitable pan is used, the display alongside the bar
graph flashes with the symbol
If there are no pans positioned on the cooking area
during the 20 second pan presence detection period:
– The cooking area switches off automatically after
20 seconds.
– The display for each cooking area will indicate
Pans
Suitable pans
Only pans with a fully magnetisable base are suitable to
cook on induction hobs.
A magnet is able to stick to every point on the whole
bottom of the pan.
Pans suitable for use with induction hobs
The pans to be used on induction cooking surfaces
must be made of metal, with magnetic properties and
with a sufficiently wide base.
Suitable pans:
Enamelled steel pans with a thick bottom.
9
Cast iron pans with an enamelled bottom.
9
Multi-layer stainless steel, ferritic stainless steel
9
and aluminium pans with a special bottom.
Unsuitable pans:
Brass, stainless steel, aluminium, refractory glass,
9
wooden, ceramic and terracotta pots and pans.

To see whether or not a pan is suitable, bring a
magnet up to its bottom: if the magnet is attracted,
the pan is suitable for induction cooking.
If you do not have a magnet, you can put a small
amount of water into the pan, place it on a cooking
area and turn the hob on. If the display shows the
symbol , the pan is not suitable.
