Siemens Synco™ living CE1B2740en
Building Technologies Central apartment unit QAX9x3 13.12.2010
Holidays and absence simultaneously
The holiday program acts on the room, ventilation and the DHW operating
mode. Also press the Absence button if, in addition to the holiday program,
you want to take advantage of the absence functions (presence simulation,
supervisory function, etc.).
When the holiday and absence functions are simultaneously active,
the central apartment unit controls room temperature, ventilation and
DHW heating in accordance with the holiday operating mode.
At the end of the holidays/special day, the operating mode for room, ventila-
tion and DHW switches from ”Holidays“ to ”Absence“.
Thus, on return from holidays, the absence function must be deactivated
again by pressing the Absence button.
During absence, make sure the temperature level is not too low (“Pre-
comfort“ or “no impact“) to allow for quickly reaching the Comfort set-
point again following absence. Slow heating systems (e.g. floor heat-
ing) require more time for reheating.
Holiday operating mode
Apartment operating mode during holidays
Select the required operating mode for the apartment during the holiday pe-
riod. The apartment operating mode during holidays applies to heating/cooling
and ventilation.
Do not set the air conditioning release mode higher than the apartment
operating mode during holidays (see page 39) to be able to release
cooling in holiday mode.
