5.5 Determine the room operating mode with
Synco (LTE mode)
In LTE-mode, the Effective room operating mode of the room controller depends on the
central
room operating mode schedule and/or on 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:

If the room operating mode in the ACS (operating booklet) is AUTO, the priorities
1 to 3 apply.
If the room operating mode in the ACS (operating booklet) is
Comfort, Precomfort,
Economy or Protection, these modes have absolute priority ("Prio 0").
The effects of Priority 1 and Priority 2 are similar in nature to states, which apply
continuously
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
