5.6 Determine the room operating mode without
a bus (stand-alone)
If no bus is connected, the Effective room operating mode of the room controller
depends on the local influences such as window contact, presence detector or room
unit.
The illustration below shows how these influences are processed by the room controller
along with their priority:
PPS2
Local
1.
DI

3.
Controller

Window contact
Presence detector
Room unit
Prio

The influence of priorities 1 and 2 is equivalent to permanent states.
The influence of priority 3 is treated as event.
The key point in time is the moment at which the state changes (edge).
If another source of third priority later changes the state, the
last known change is
valid
.
If there is no bus connection, the controller assumes the following defaults:
Use = Building in use.
Occupancy = Occupied.
STOP
