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
.
STOP
