Determine the room operating mode with
Synco (LTE mode)
In LTE-mode the e ffective room operating mode of the room controller depends on the
central Room operating mode time schedule and/or on local influences such as window
contacts, presence detectors or room units.
The diagram below shows how these influences are processed by the room controller,
and 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 Priority 3 influences are treated as events .
The key factor is the moment at which the state changes (trigger edge).
If the mode is later changed by another source of priority 3, the last change
applies.
