The presence detector is connected directly to a digital input on the room controller
(see page 142); alternatively an EIB/KNX presence detector connected to the EIB/KNX
bus may be used (see diagram below).
The two inputs are OR-linked: If one signals presence, presence applies.
Since EIB/KNX presence detectors are available from a variety of manufacturers, the
name of the S-mode output communication object varies accordingly.

Master/slave applications:
Bindings are required in S-mode, in order to transmit the slave presence detector status
to the master.

The output communication object Effective
occupancy shows the occupancy status of the room
(based on a combination of time schedule and
presence detector).
In the case of integration into a building automation
and control system, the data is mapped to the
following output communication object:
