System overview System functions The Synco™ living system offers you a host of choices. In addition to room climate and DHW heating control, the system enables you to control a ventilation system, lighting and blinds, to monitor smoke detectors and door / window contacts as well as to release air conditioners. Central unit Central apartment unit QAX910 The heart of the system is the QAX910 central apartment unit.
Room temperature setpoints The room temperature setpoints for heating and cooling can be set individually for each room and for each room operating mode (Comfort, Precomfort, Economy and Protection). The room operating mode can be set or change over automatically based on the respective room time switch. The room time switch influences heating and cooling. Separate time switches are available for ventilation and DHW.
Multi-controller RRV934 Receives the flow temperature setpoints of the assigned room groups from the central apartment unit (radio) and controls the flow temperatures accordingly. To do this, the controller measures the flow temperatures and controls the wired actuators of the respective room group. The precontroller additionally allows for minimum or maximum limitation of the return temperature.
Ventilation control The central apartment unit has a ventilation time switch providing 6 switching points for each day for 7 weekdays and one special day. Each switching point allows for changing over between the ventilation operating modes (Comfort, Precomfort and Economy). Ventilation stage control is carried out via air quality, relative room humidity, current apartment operating mode (Comfort, Precomfort, Economy, Protection) or ventilation stage selection.
Weather station The central apartment unit receives the outside temperature and the atmospheric pressure from the meteo sensor. Meteo sensor QAC910 The meteo sensor acquires the outside temperature and the absolute atmospheric pressure and transmits both via radio signal to the central apartment unit. The current measured values of outside temperature and atmospheric pressure as well as the pressure trend can be shown in the quiescent picture.
Operation of lights and blinds The lights and blinds can be controlled with the central apartment unit’s softkeys. Prerequisite for this operation is that the light and blind actuators used have a binding facility for KNX-RF (KRF960, KRF961, Siemens GAMMA wave or Hager tebis TX radio) or KNX TP1. Supervisory functions The central apartment unit monitors the connected window contacts, door contacts and smoke detectors.
System components The following components can be used in the Synco™ living system or can be combined with it: Synco QAX910 Central apartment unit QAW910 Room unit QAA910 Room temperature sensor QAC910 Meteo sensor RRV912 Heating circuit controller, controls one 3-position or two 2-position actuators RRV918 Heating circuit controller, controls up to eight 2-position actuators RRV934 Multi-controller Controls up to 3 fan speeds and the HR bypass, or controls 2 independent room groups.
GAMMA wave DELTA reflex smoke detector with smoke detector module wave UNI M 255 Door and window contact wave AP260 (wireless) GAMMA wave light and blind actuators, switchable sockets and handheld transmitters can also be used Hager tebis TX radio Light and blind actuators from Hager can be used The central apartment unit can also control light and blind actuators via KNX TP1 (S-Mode). In that case, configuration with the ETS (EIB tool software) is required.
Central apartment unit QAX910 Operating elements All operating elements are located on the front of the unit. The buttons provide the following functions: DHW button, ventilation button The button is used to operate DHW and ventilation.

Normally, these settings are sufficient for operating the plant. Service level This operating level contains extended settings that are only rarely used.
General Absence If you leave the house for a few hours, you can press the Absence / Supervision button to inform the central apartment unit about your departure. Shortly pressing the Absence / Supervision button opens the presence window which allows you to enter the desired state "Absent" or "Present" via the Arrow buttons or the Absence / Supervision button.
During the set supervision delay, you can close the corresponding doors and windows. After all supervised windows are closed, the constant signal sound turns into a beep whose interval doubles during the last 15 seconds of the set supervision delay. If a supervised window or door is opened during the supervision period, an associated fault message is triggered and other predefined actions are initiated (with an adjustable message delay for doors).
The central apartment unit display shows MAN for manual mode and the symbol for a manually set apartment operating mode. The selected apartment operating mode is valid until reset manually to Auto. The apartment operating mode can also be selected via the following operating line: Main menu > Apartment > Apartment operating mode > Preselection: Auto The room control loops and ventilation maintain their setpoints in accordance with the respective operating modes.
Summer operation of heating Select the point in time your heating system should switch to summer mode. In summer mode, all room operating modes switch to Protection, the valves travel to the position defined for summer operation and DHW heating switches to the electric immersion heater, if installed. In the case of summer changeover via the external switch, this parameter has no impact (hidden). Input function “Summer operation“ must be appropriately configured when commissioning the plant.
Antilime function To prevent valves and pumps from seizing, the controller periodically drives all valves to their fully open positions and activates all connected pumps in a stepwise fashion at predefined points in time.
Rooms 1 – 12 Room operating modes In addition to the operating mode for the entire apartment, each room has its own operating mode which you can select to suit your needs. Main menu > Rooms > Room X > Room operating mode > Preselection: Auto The room is controlled in accordance with the time program and the holiday / special day program. Comfort The room is maintained at the Comfort setpoint. Precomfort The room is maintained at the Precomfort setpoint (for short periods of absence, e.g.
Plant operating mode The individual rooms can be configured merely for heating/cooling operation, or for automatic changeover between the two operating modes. Main menu > Rooms > Room X > Room operating mode > Plant optg mode: Auto The plant operating mode is changed over automatically based on room temperature and mixed outside temperature. Heating The plant is in heating mode. Cooling The plant is in cooling mode.
To change over between the plant operating modes heating and cooling, the preset H/C changeover locking time must be expired. This avoids frequent changeover. The central apartment unit checks the mixed outside air temperature as a second criterion and compares it to the outside temperature heating limit and the outside temperature cooling limit (see page 31).
Room number Room name Factory setting Setting --- 7 8 9 --- --- 10 --- 11 --- 12 --- --- = no impact (according to the time program) = Comfort = Precomfort = Economy = Protection Changeover of the respective room operating mode takes place only if the room operating mode during absence is set to a lower level than the room operating mode for normal operation. Release of air conditioner Set the room operating mode that is to be released for cooling by the air conditioner.
Room temperature setpoints You can adjust the room temperature setpoint for each individual room and for heating and cooling (Comfort, Precomfort, Economy, Protection). The central apartment unit maintains the respective setpoint, depending on the selected apartment / room operating mode and / or time program.
Readjustment of room unit The room temperature setpoint readjustment (+/- 3 K) made on the room unit can be displayed on the central apartment unit for each room: Main menu > Rooms > Room X > Room setpoints > Readjustm room unit: The readjustment made on the room unit only acts on the Comfort and the Precomfort setpoint.
Copying switching times When you scroll to the end of the switching point list, option “Copy to:“ will appear. You can copy the switching times of the respective day to any other weekday (including the special day) or to a number of weekdays (Mo – Fr or Mo – Su). Monday Copy to: Setting new switching points For every weekday and the special day, you can set and define up to 6 switching points where the room temperature setpoint should change.
Monday - - :06:00 -From Comf To delete a switching point, press the Arrow buttons until “- - : - -“ appears (before 00:00 and after 24:00).
Economy increase The state of the Economy increase (Inactive / Active) can be queried for each room: Main menu > Rooms > Room X > Room state > Eco increase: Setpoint limitation This operating line shows if setpoint limitation is active in the room (triggered by the central communication unit via wire bus).
Optimum start / stop control acts between all operating levels, except when switching between Precomfort and Comfort: Comfort mode Precomfort mode Economy mode Protection The optimization time (forward shift) can be limited to a maximum value, separately for optimum start and optimum stop control (optimum start control 48 hours / optimum stop control 06.00 hh.mm). When setting the optimization time to ---- or 00.00, the function is deactivated.
Room number Room name Factory setting Max temp. alarm Min temp. alarm 7 8 9 10 11 12 ---- ---- ---- ---- ---- ---- Window airing function As soon as the central apartment unit detects an open window, the window airing function is activated in the corresponding room. In that case, the radiator control valve is limited to its current travel, even if the room temperature drops. If the window remains open after the set window airing hold time, the room operating mode is lowered to Protection mode.
Silent mode The SSA955 radiator control actuator can also be operated in silent mode when used in noise-sensitive rooms (e.g. in the sleeping room). Silent mode increases the actuator’s power consumption, thus reducing battery life.
Room group This parameter shows the room group to which the corresponding room was assigned during commissioning (additional configuration). Main menu > Rooms > Room X > Room settings > Room group: Room groups States The following paths can be used to display the various states of the room group. Return temperature actual value Shows the current return temperature actual value of the corresponding room group.
Room valve position max Determines the room within the room group whose valve is open the widest. The opening value (calculated value for heat demand without influence of other functions) is displayed in this operating line. Main menu > Room groups > Room group X > State > Room valve pos max: Ventilation Operating mode Stage selection The stage selector allows for either defining automatic stage selection or setting the ventilation plant to a fixed stage.
State Displays the current ventilation operating mode (Comfort, Precomfort, Economy, Protection). Main menu > Ventilation > Operating mode > State: Reason Displays the reason for the current ventilation operating mode (state).
Stage setpoints Stage assignment to operating modes The individual ventilation operating modes can be assigned to the corresponding ventilation stages via stage setpoints. This setting has no influence, if ventilation is controlled by relative humidity or air quality.

Indoor air quality control Indoor air quality is controlled to the setpoint of the current ventilation operating mode. The central apartment unit acquires air pollution, compares it to the setpoint and switches between the ventilation stages as needed. The switching between the ventilation stages depends on the number of existing ventilation stages. The current room air pollution (ppm) is displayed on the central apartment unit. The stage selection setting must be set to Auto (see page 45).
Stage setpoint for humidity limitation If the measured humidity exceeds the humidity limit value, ventilation is started at the stage set here. Main menu > Ventilation > Humidity limitation > Stage setpoint: Factory setting Setting Stage 1 Off Stage 1 Stage 2 Stage 3 Humidity limit value Specify the desired humidity limit value (1..99% r.h.). Main menu > Ventilation > Humidity limitation > Humidity limit: Factory setting Setting 85% r.h.
Stage setpoint for night cooling Specify here the stage for the ventilation plant when night cooling is active. Main menu > Ventilation > Night cooling > Stage setpoint: Factory setting Setting Stage 1 Off Stage 1 Stage 2 Stage 3 Precooling time max Night cooling is released only during the set maximum precooling time (0..2880 min). When the setting is 0 min, night cooling is disabled.
Runtime forced ventilation Forced ventilation is active for the runtime set for forced ventilation (0..60 min). After expiration of this time, ventilation returns to the ventilation stage prior to forced ventilation. Main menu > Ventilation > Ventilation settings > Runtime forced vent: Factory setting Setting 30 min Impact of window switches If at least one window is open in one of the set rooms, the ventilation stage is activated as per the setting (see page 47).
Forced DHW charging With a long push on the central apartment unit’s DHW button, one-time forced charging of the DHW storage tank to the Normal setpoint is triggered. During the time forced charging is active, the DHW symbol on the display flashes .
Operating mode via contact Specify the type of DHW operating mode the controller is to change over to when an external operating mode contact is connected (e.g. teleswitch for remote operation by phone). Operating mode changeover via external contact overrides all other operating mode settings. The input function “operating mode contact” must be configured during commissioning. The same operating mode contact is used for heating / cooling, ventilation and DHW.
Actual value of the DHW temperature The actual value of the DHW temperature can be displayed: Main menu > DHW > DHW state > Act val DHW temp: DHW temperature setpoint The current DHW temperature setpoint can be queried: Main menu > DHW > DHW state > DHW temp setpoint: Operating state of charging pump and electric immersion heater The current operating state of the charging pump and the electric immersion heater can be displayed: Main menu > DHW > DHW state > Charging pump: Main menu > DHW > DHW state > El
Changeover to electric immersion heater Select whether in summer operation the DHW should be heated by the electric immersion heater. Yes When the plant switches to summer operation (refer to page 30), the DHW is heated by the electric immersion heater. This means that heat generation can be switched off in the summer. No DHW is heated by the heat source in the summer also. This means that heat generation in the summer remains in operation (emergency operation).
Switching groups Operating the switching groups Switching groups 1 – 4 can be operated via the 4 pairs of softkeys on the central apartment unit. The functions of the switching groups (e.g. switching or dimming lights, opening or closing blinds, calling up info pages or scenes) were defined when the plant was commissioned. Switching groups 5 – 8 have no buttons for direct access.
You operate a switching group defined as Scene under: Main menu > Switching groups > Switching group X > Scene A or B > Trigger scene: The text displays for scenes A and B can be adjusted to suit your needs (refer to page 60). Scenes When commissioning the plant, the softkeys of the central apartment unit (switching groups 1 – 4) can be programmed for triggering scenes (scene symbol appears on the display of the key assignment).
Select the event (or the events) that triggers a switching group configured for Blind: Main menu > Switching groups > Switching group X > Events up cmd: Main menu > Switching groups > Switching group X > Events down cmd: Select the event (or the events) that triggers a switching group configured for Scene: Main menu > Switching groups > Switching group X > Scene A or B > Events scene: The following events are available for triggering switching group functions: Absence ON Execution of command when changing
