12.5.1 Cookware detector signal
Every cooking zone has a cookware detector that only starts the cooking if there is a well positioned
recipient with the suitable characteristics present on the plate. If the container is not well positioned or
isn't made of the correct material and still tries to activate the burner, after a few seconds from the
burner's activation, the
symbol will appear on the display.
12.5.2 Residual heat
Each cooking zone is equipped with a residual heat warning device. After any burner is switched off, a
flashing
may appear on the front zone. This warns that the cooking zone concerned is still very hot.
Cooking can be restarted even while the
is flashing.
12.5.3 Cooking hob lock-out
When not in use, the hob can be “locked” from being accidently turned on by children. With the hobs
turned off turn the knobs for hobs 2 and 4 completely to the left until 5 L appears on the display. Then
release the knobs. To unlock it repeat the same operation: The burners' displays will show a 0 that will
indicate that the burners' lock has been deactivated.
12.5.4 Circuit board thermal protection
The appliance is provided with a device that constantly measures the temperature of the electronic
circuit board.
If the temperature surpasses certain values, the device will activate certain functions to lower the
temperature and allow the glass-ceramic hob to continue to work correctly.
