Dew Point; Absence - Siemens Synco living QAX913 Mounting And Commissioning

Dew point

Radiator/floor cooling is disabled by closing the contact of an external dew
point monitor, or enabled when the contact opens.
The dew point monitor closes the room group mixing valve if a room group
precontroller is installed. If only a room group pump is installed, the dew point
monitor shuts off the room group pump. If there is neither a precontroller nor a
room group pump, the dew point monitor closes the room valves. The dew
point monitor always acts on both room groups.
Specify if an external dew point monitor is used and from where the central
apartment unit receives its status.

Absence

"Absence" is triggered when the respective input terminal closes.
The room temperature setpoints are switched to the respective absence set-
point (per room) and any activated time program for presence simulation
starts via the switching groups.
DHW heating, ventilation and cooling also operate according to the operating
mode selected for the period of absence.
See the operating instructions for a detailed description of "Absence".
Specify if an external absence contact is used and from where the central
apartment unit receives its status.
