the LEDs light up at night
and switch off during the
day. To change the setting to

NOTE: when the OFF and AUTO lighting modes are active, every time the entrance panel is powered, the
buttons light up for the duration of the start-up phase (10 seconds maximum).
In AUTO mode the twilight sensor checks the ambient light level every 9 minutes; if the measured values
exceed the specified minimum/maximum thresholds, it is activated/deactivated accordingly.
