CHAPTER 4: TECHNICAL ASSISTANCE
4.1: DEMO MODE:
Getting ready to use Demo Mode:
1. the hob is on
2. all the inductors are off
To select DEMO function, press and hold for 6 seconds TIMER "+" and "-" buttons simultaneously; then
POWER ON and BUTTON LOCK LED will fl ash for 1 second, now press the CLOCK button. The message
"dE MO" will appear on the display every 5 seconds for 1 second.
To quit the function, follow the same procedure you have followed to enter it.
Remark:
Demo Mode is available only in hobs fi tted with a TIMER.
If Demo Mode is on, the TIMER indicates the minutes elapsed displaying the seconds.
4.2. AUTOTEST:
4.2.1: Autotest activation sequence:
Getting ready to use Autotest: the hob is off.
Press all the buttons from left to right and from the upper side to the lower side of the interface, without lea-
ving anyone of them. As you touch the icons with your fi nger, the appliance will emit a beep to confi rm it.
4.2.2: Sequence executed by the appliance
During the Autotest, all the inductors are energized beginning from the left-hand one on the lower part (the
fi rst one) up to the right-hand one on the lower part (the last one), in a clockwise order. Every inductor will
be energized at the maximum power for 15 seconds, then in Booster modality for the remaining 15 minutes,
even if the normal operation does not provide for it.
Between the ignition of one inductor and the next one, there is a pause of 30 seconds, to give the engineer
time for changing water contained in the pan during the Autotest.

4.2.3: How Fault are displayed.
If the hob does not indicate a Last Fault, the Autotest sequence will start immediately.
In case the appliance signals a Last Fault, before starting up the Autotest, the Last Fault will be displayed
for 20 seconds, and then, the Autotest sequence starts.
The Last Fault will be deleted from the memory at the end of the whole Autotest sequence.
If the Autotest is interrupted during the execution (because of the hob being turned off or powered off), the
Last Fault is not memorized as statistics, but it will be displayed by the appliance the next time the Autotest
function will start.
Important: The Fault will be displayed in all 7-segment if it affects the whole hob. It will be displayed
by two of the Power Board 7-segment, if the fault is due to one of these two Boards.
If the fault is due to only one Inductor, the Fault will be displayed only in the 7-segment
connected to the Inductor damaged, for example, a Fault to the NTC
