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:
Central (ACS)

• 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 .
