Ordering references Product no. Product number Designation QAX913-9 S55621-H126 Central apartment unit with mounting instructions Functions Main functions The central apartment unit manages heating, cooling, ventilation and hot water control of an apartment with up to 12 rooms. It also controls air conditioners (split units), lighting and blinds actuating devices and monitors light actuators, door and window switches as well as smoke, CO, natural gas and water detectors.
PAGE 5
Parallel operation of radiator control actuators Up to 6 SSA955 radiator control actuators can be combined to one room and operated in parallel. The first radiator control actuator (master controller) assumes actual room control plus wireless control of the other assigned radiator control actuators (parallel controllers). Zone control Multiple heating circuits connected to common heat distribution can be controlled jointly as a zone.
PAGE 6
Dew point monitoring A condensation monitor (QXA2000, AQX2000) monitors the dew point on the flow pipe. The condensation monitor acts simultaneously on both room groups (1 dew point monitor per QAX913). Floor cooling enable Floor cooling is enabled: − − − − − Manually on the QAX913. Via external switch (digital). Via programmable date. Via composite outside air temperature. Via KNX S-mode.

Specific monitoring and operating function Door and window switches The central apartment unit monitors the connected door and window switches. A monitor delay can be parameterized on door and window switches as well as a detector delay for door switches. Setting the monitor delay to infinity only re-enables monitoring after the doors are closed. Windows and doors that are opened when monitoring is enabled are automatically excluded from monitoring.
PAGE 8
Blind control The central apartment unit or external switches (transmitters) can be used to adjust blinds in steps, or to fully open or close them by a press of a button. In addition to the manual adjustment of blinds, the blinds settings can be made via the internal time switch (the time switch can be processed "always" or "for absences only"), presence simulation, scenes or events (e.g. twilight, absence).

Specific functions to acquire and display consumption data Consumption data acquisition Integrate the consumption data interface WRI982 to display energy consumption on the central apartment unit and send it to a service provider via web server OZW772. Monthly and annual cutoff values are displayed and forwarded in addition to current meter readings. A corresponding info page is maintained for each meter type. Available meter types and max.
PAGE 10
Synergyr integration 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).

Establishing the wireless connection The individual wireless components are connected to the central apartment unit by selecting the room / switching group / function to be assigned to the new wireless components and then pressing the connect or function button for the corresponding components. When connecting devices from the Hager tebis RF range, the TX100 configurator is required (supplied by Hager).

Apartment timer button This button is used to set and activate the timer function for selected rooms. Rooms are heated or cooled to the desired setpoint (Comfort, Precomfort or Economy) and operates ventilation to the corresponding setpoint stage while the timer function is enabled. Mode button This button selects the operating mode for the apartment (Auto / Comfort / Precomfort / Economy / Protection). The apartment operating mode simultaneously acts on room control and ventilation.

Notes on engineering and operation Mounting location • Comply with all local regulations on electrical systems • The central apartment unit is designed for surface mounting • Mount the QAX913 in a space that is easily accessible (e.g. in the living room or in the hall). The mounting height above the floor should be chosen such that the unit is easily accessible. The QAX913 does not house a temperature sensor.
