System overview System functions The Synco™ living system offers you a number of choices. In addition to room climate and DHW heating control, the system enables you to control a ventilation system, lighting and blinds, monitor smoke detectors and door/window contacts and water detector, issue alarm message using sirens, release air conditioners as well as acquire and display consumption data. Central unit Central apartment unit QAX903 or QAX913 The heart of the system is the central apartment unit.
The rooms are grouped into one apartment. The operating modes and a holiday/special day program can be set for the apartment. The apartment operating mode allows for overriding the individual room operating modes. 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).
They also facilitate the direct connection of an apartment pump and of DHW heating. 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.
With central cooling (entire apartment) or radiator/floor cooling (per room) via a common 2-pipe heating/cooling system, cooling is accomplished using the same components as heating control. 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).
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.
Consumption data acquisition The consumption data interface allows for connecting both M-bus meter and pulse meter to acquire consumption data. The acquired data is displayed on the central apartment unit and sent to the web server for remote reading via KNX TP1 (optional). WRI982 consumption data interface Max 3 M-bus meters and 2 pulse meters can be connected with each consumption data interface. The consumption data are sent to the central apartment unit via KNX radio.
QAC910 Meteo sensor RRV912 Heating circuit controller Controls 3-position or two 2-position actuators RRV918 Heating circuit controller Controls up to eight 2-point actuators RRV934 Multi-controller Controls up to 3 fan speeds and the HR bypass, or controls 2 independent room groups. Universal inputs and outputs.
GAMMA wave DELTA reflex smoke detector with smoke detector module wave UNI M 255 (QAX913 only). Door and window contact wave AP260 (wireless) GAMMA wave light and blind actuators, switchable sockets and handheld transmitters can also be used (QAX913 only). Hager tebis TX radio Lighting and blinds actuators from Hager can be used (QAX913 only). The central apartment unit QAX913 can also control lighting and blinds actuators via KNX TP1 (S-mode). This requires configuration with ETS (EIB tool software).

The setting is effective only if the presence simulation of the corresponding switching group as described above is enabled. Main menu > Switching groups > Switching group X > Presence simulation > Function: Random The switching group actors are switched on or off within the set period at random intervals of 3 to 30 minutes. The first switch-on of each switching group also is at random.
Any open windows and doors can now be closed. After you close the supervised window, the constant signal becomes a beep that doubles in the last 15 seconds of supervision delay. The remaining supervision delay time is also displayed on the central apartment unit. The desired delay time (00.00..59.55 m.s, "---" indefinite) can be set via the following commands and applies to all windows and doors: Main menu > Supervision > Supervision delay: Factory setting 05.00 m.
If a supervised window is opened, the message "Window open" appears. In addition, the buzzer, status output and a switching group function can be activated. The "Window open" fault message remains active until supervision is changed, even after all supervised windows are closed. Main menu > Supervision > Windows > Rel "Partly monit": Main menu > Supervision > Windows > Rel "All monit": Factory setting ---- (none) Doors Up to two doors can be supervised.
If event "Window/door supervision" is activated for the buzzer or at the status outputs, the alarm is sounded at the central apartment unit and/or he corresponding status output is activated (e.g. siren) after the delay time has expired. Event buzzer and status output Determine the event for which the buzzer and/or the status output is to be activated (smoke, window/door supervision, water leak, gas leak, CO alarm, panic, emergency or fault 1 – 3).
Main menu > Supervision > Signaling > Buzzer > Supervision confirm: Main menu > Supervision > Signaling > Status output X > Supervision confirm: No No supervision confirmation (factory setting). Yes Supervision is confirmed. Note that brief activation of an outdoor siren (up to 120 dBA) may be considered a nuisance by neighbors.
Display of due day values The current meter readings are saved together with the due date for each meter on the set due day. A due day value for heating and cooling is displayed for combined heat/cooling energy meters. Due day values generated in meters or consumption data interface are updated once a day by the central apartment unit. After reaching the due day, it may take up to two days in some cases to display the new due day values on the central apartment unit..

Error messages Device faults are sent to the central apartment unit as error messages and are displayed with the error symbol. Device faults are communication breakdowns or short-circuits / open-circuits of sensors in the room unit. The error symbol disappears as soon as device errors are no longer present. If communication with the central apartment unit is interrupted, the connection and error symbols are displayed until communication is reestablished.
AFK914/C01 handheld control Operation All operating buttons are located on the front of the handheld control AKF914/C01. The handheld control communicates via radio with the central apartment unit. A handheld control button can be assigned the following functions: – – – – Activate (all monitored) / deactivate supervision. Trigger switching group command. Activate emergency alarm. Activate panic alarm. The LED is lit blue for max. 2s as soon as a button is pressed on the handheld control for more than 0.
pervision. The blue LED first is lit for max. 2 s; the red LED then briefly blinks 3 times. A window open at the time of supervision activation can be opened and closed any number of times (e.g. by wind) without triggering an alarm. A door open at the time of supervision activation can be left open without triggering an alarm. However, the door is supervised as soon as it is closed. Supervision delay is off, i.e. all doors and windows are supervised with immediate effect.
Radio plug adapter Operation KRF960 (switching) LED display functions: • LED lit: Contact closed • LED off: Contact open.
Service Function test for water detector QFP910 Check the function of the water detector once a year. To do this, immerse both water detector contacts in water. A corresponding action is triggered depending on the central apartment unit's configuration; e.g.: – The safety shutoff valve of the main line is closed => no more water in the entire building. – The buzzer of the central apartment unit is activated.
In that case, the central apartment unit switches from the quiescent picture to info page “Device state“ to show the device with the exhausted batteries (provided there is no more severe fault). After a certain period of time, the display . returns to the quiescent picture and displays error symbol The result of automatic battery monitoring is not displayed on the batterypowered devices, with the exception of room unit, handheld control, door/window contact and smoke detector .
Change batteries To ensure trouble-free operation of the battery-powered devices, replace the batteries as soon as they are close to empty. Avoid complete discharge of batteries, as otherwise batteries may leak. For this reason, replace the battery as soon as the display tells you to. Contact your building's supervisor if your central apartment unit on the info page shows a low battery charge for a meter under "Device status". Only authorized staff may exchange meter batteries.
