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 ventila-
tion 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. It facilitates operation of the entire
system and ensures communication between the
different devices.
Heating / cooling
Models / Combinations
Heating and / or cooling can be performed in different models and combina-
tions:
Heating
•Radiator heating (per room)
•Floor heating (per room)
•Air conditioner (per room)
Cooling
•Central (entire apartment) via common 2-pipe heating/cooling system
•Cooling release output for external component (per room)
•Air conditioner (per room)
Heating / cooling mode
The individual rooms can be configured for pure heating or cooling mode or
for automatic changeover between the two operating modes.
The central apartment unit switches the apartment or individual rooms to
cooling or heating mode as per the settings.
Plants with rooms comprising controllable air conditioners (e.g. air con-
ditioner via Zennio module) can heat or cool rooms independent of
each other.
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.

11 / 100
Siemens Synco™ living Operating instructions CE1B2707en
Building Technologies System overview 23.08.2008
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.
Heating control
The central apartment unit collects the heat requests per room group from the
various rooms to deliver the total heat request to the heat generation control-
ler.
The unit transmits the information for precontrol of the respective room group,
flow temperature setpoints and the desired minimum or maximum limitation of
the return temperatures to the multi-controller.
In addition, it transmits the actual values of the room temperatures and the
room temperature setpoints to the heating circuit controllers and radiator
control actuators which then calculate the positioning signals required for the
actuators.
The positioning signals for the multifunctional relays of the heating circuit
controllers / multi-controllers are generated by the central apartment unit.
For room temperature control, the following system components are available:
Room unit QAW910
On the room unit, the required room operating mode can be
selected, the room setpoint temperature readjustment can be
made, and the room timer function can be set. The room unit
also acquires the current room temperature. All data are trans-
mitted to the central apartment unit via radio.
Room temperature sensor QAA910
The sensor acquires the room temperature and sends it to the
central apartment unit via radio signal.
Heating circuit controllers RRV912 and RRV918
The controllers receive the setpoints and actual
values of the various rooms from the central apart-
ment unit (via radio signal) and forward the resulting
positioning signals to the wire-bound actuators.
They also facilitate the direct connection of an apart-
ment pump and of DHW heating.

12 / 100
Siemens Synco™ living Operating instructions CE1B2707en
Building Technologies System overview 23.08.2008
Multi-controller RRV934
Receives the flow temperature setpoints of the as-
signed room groups from the central apartment unit
(radio) and controls the flow temperatures accord-
ingly.
To do this, the controller measures the flow tempera-
tures and controls the wired actuators of the respec-
tive room group.
The precontroller additionally allows for minimum or
maximum limitation of the return temperature.
Radiator control actuator SSA955
The actuator receives the setpoint and the actual value
(provided a room sensor or room unit is present) of the
respective room from the central apartment unit via
radio signal and readjusts the radiator valve accord-
ingly.
If no room sensor or room unit is installed, the radiator
control actuator uses its own measured value of the
room temperature as the actual value.
Door / window contact wave AP 260
When a door or window is left open, the stroke of the
radiator valves in the respective room is limited to the
current position in order not to waste energy. If the
window is still open after expiration of the set window
airing time, the room operating mode is lowered to
Protection. The function acts on the wire-bound actua-
tors used with the RRV912 / RRV918 heating circuit
controllers and the wireless SSA955 radiator control
actuators.
Cooling release
Cooling is released based on the respective room operating mode and mixed
outside air temperature. The room may not be in heating mode.
When door and window contacts are open, the central apartment unit can lock
cooling of the respective room.
Cooling is released for individual rooms or for the entire apartment (with cen-
tral cooling).
The setpoint is determined by the current room operating mode (manual or as
per room time switch). The room unit serves as room temperature sensor with
a possible option to adjust the setpoint.
With central cooling (entire apartment) via a common 2-pipe heating/cooling
system, cooling is accomplished using the same components as heating
control.

13 / 100
Siemens Synco™ living Operating instructions CE1B2707en
Building Technologies System overview 23.08.2008
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, Protec-
tion) or ventilation stage selection. The stage setpoints are changed based on
the ventilation time switch which is independent of heating and cooling.
Short-term room air pollution can be remedied via the forced ventilation func-
tion.
For brief absences, an absence operating mode is available. Extended ab-
sences are covered by a holiday program.
Ventilation control responds to open windows (if they have the associated
window contacts), smoke (if smoke detectors are connected) and external
ventilation contacts.
Night cooling can be used for cooling with possible control of a heat recovery
bypass to avoid heat recovery.
Multi-controller RRV934
The multi-controller allows for controlling ventilation
stages and heat recovery bypass. It has inputs to
connect an air quality and humidity sensor. The
other inputs and outputs are universal.
DHW heating
The central apartment unit controls DHW heating of a locally connected DHW
storage tank or facilitates remote operation of a DHW storage tank connected
to the heat generation controller or some other central apartment unit.
For that purpose, the central apartment unit is equipped with a DHW 7-day
time switch with 6 switching times per day for changeover between Normal
mode and Reduced mode.
The central apartment unit can also be used for triggering manual forced
charging of the DHW storage tank. The current DHW temperature appears on
the display of the central apartment unit.

14 / 100
Siemens Synco™ living Operating instructions CE1B2707en
Building Technologies System overview 23.08.2008
Weather station
The central apartment unit receives the outside temperature and the atmos-
pheric 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 pres-
sure as well as the pressure trend can be shown in the quiescent picture. The
change of atmospheric pressure over the last 3 hours is displayed with an
arrow.
In addition, based on the changes and the absolute value of the atmospheric
pressure, the weather trend (sunny, partly cloudy, rainy) is determined and
shown with a symbol in the quiescent picture. The entered altitude is also
included.
The progression of outside temperature and atmospheric pressure over the
last 24 hours can be made to appear on 2 info pages.
Lighting and blinds control
The central apartment unit allows for controlling lighting and blinds.
Lighting control
Connected lamps can be dimmed and switched either via the central apart-
ment unit or external switches (transmitters).
All the various light settings can be stored as a scene and retrieved at a later
point in time, if required.
In addition to manual light settings, the settings can also be made via the built-
in time switch, presence simulation or events.
Blinds control
Using the central apartment unit or external switches (transmitters), blinds can
be adjusted in steps, or they can be fully closed or opened by pressing a
button.
All blind positions (fully open or fully closed) can be stored as a scene and
retrieved at a later point in time, if required.
In addition to manual blind settings, the settings can also be made via the
built-in time switch or events.
The light settings and blind positions can be jointly stored as a scene
or jointly readjusted when calling up a scene.

15 / 100
Siemens Synco™ living Operating instructions CE1B2707en
Building Technologies System overview 23.08.2008
Operation of lights and blinds
The lights and blinds can be controlled with the central apartment unit’s soft-
keys.
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.
Door / window contact wave AP 260
The door / window contacts detect an open door or
open window and transmit this information via radio
signal to the central apartment unit. They can also be
used as detached digital inputs (e.g. for monitoring the
door of a domestic freezer).
DELTA reflex smoke detector with smoke detector
module wave UNI M 255
The smoke detector detects instantly the smoke gener-
ated by a fire and sets off an alarm (flashing LED and
acoustic signal on the device, smoke signal via radio to
the central apartment unit).
Alarms
If a fault occurs (smoke detector, window contact, heating, etc.), it is shown on
the display of the central apartment unit. In addition, the central unit can gen-
erate an acoustic signal and forward it via bus (KNX TP1), or it can close a
contact for activating an external signal source.
Supervision of devices
The connected wireless, communicating devices are monitored at regular
intervals. When there is no transmit signal or when batteries are close to
exhaustion, an error message will appear on the display of the central apart-
ment unit.
