Display after battery change
After insertion of the new batteries,
the full display appears for 2 sec-
onds. Then, the room unit changes to
Normal operation.
The room operating mode settings are interrogated by the central
apartment unit. Any active room timer function will not be reactivated.
After inserting the new batteries, the battery capacity is checked at the room
temperature sensor QAA910 and the meteo sensor QAC910 . During the
check, the green LED lights up for 2 seconds, provided the batteries have
sufficient capacity.
After the battery check, the devices directly switch to Normal operation. The
LED will extinguish again.
