Siemens Central apartment unit with consumption data acquisition QAX913 CE1N2740en
Building Technologies 2016-01-30
The Synco living ECA system is fully compatible with the Synergyr system and
permits a conversion of individual units into a Synergyr system (partial migration).
The meter information is displayed on the QAX913 central apartment unit and
moreover forwarded via the Synergyr building bus to the OZW30 building central
station.
Detailed information the Synco living ECA System is available in the datasheet on
the consumption data interface (N2735en).
Device and system functions
Synco living features a number of inputs and outputs which can be used either via
the universal input / universal output of the central apartment unit (locally) or the
universal inputs / universal outputs of the RRV912 / RRV918 heating circuit con-
trollers or the RRV934 multicontroller.
The inputs and outputs can be assigned the following functions:
Inputs
• Changeover of operating mode (apartment operating mode and / or hot water
operating mode)
• Changeover to summer operation
• Cooling enable
• Heating / cooling changeover
• Changeover of monitoring function
• Dew point monitor
• Flow and return sensor
• Ventilation switch 1 and 2 (e.g. Hygrostat)
• Chimney mode
• Triggering the absence function
• Twilight function (e.g. by means of a twilight switch) for triggering a switching
group or for enabling presence simulation)
• Fault inputs 1 – 8
