5.3.6 Cooking hob lock-out
When the hob is on, it can be locked to avoid accidental modifications to the cooking values set. The lock remains on even after the hob has been switched off. It is present only on the models that have
the symbol 
.
To activate the lock, with the hob on, press the keys 
and 
near the cooking zone
simultaneously until the symbol 
appears on the display.
To deactivate the lock, in the same way, press the 
and 
keys near the locked cooking zone
simultaneously until the symbol 
disappears from the display.
The figure above shows the “grouping” of the cooking zones. When one hotplate is locked, the hotplate in the same group is also locked.
Even when the hotplate is locked, it can be switched off pressing its ON/OFF key. In this case, the lock is held until the next time it is switched on: to set a cooking level switching on a locked hotplate, it must first be unlocked following the procedure as described in this section.
5.3.7 Power management
To optimise the energy consumption, the groups made up of two hotplates (see figure above) are prevented from supplying more than a determined maximum operating power. If the value set for the two hotplates exceeds the permitted power, the electronic circuit board will automatically maintain the maximum level permitted modifying the power supplied by the hotplates. The power level selected by the electronic circuit board will still be visible on the display.
5.3.8 Control circuit board thermal protection
If the cooking zones cause overheating of the internal electronic circuit board, the heat will be switched off automatically. This switches off power to the hotplates and F7 will light up on the power LEDs.
5.4 Limitations to the operating duration
The electronics of this appliance limit the cooking duration according to the power selected. After the maximum time period has gone by, the cooking zone switches off, the appliance emits an audible signal and AS(automatic stop) appears on the display.
Power level set | Maximum cooking duration in hours |
Levels 1 to 9 | 8 hours' cooking at most |
Levels 10 to 14 | 2 hours' cooking at most |
Level 15 to | 1 hour's cooking at most |
