If a LON subscriber (e.g. Vitotronic control unit) fails,
no further data from this subscriber will be transferred
to the KNX/EIB system.
The KNX/EIB system can display a corresponding
error message if the data point error message has
been assigned for this LON subscriber.
Restoring the factory settings
1. Simultaneously press and hold buttons "T2" and
"T4".
2. Switch the plug-in power supply unit OFF and ON
again.
3. Release buttons "T2" and "T4" as soon as the
LEDs flash briefly 3 times.
