Congratulations …
… on choosing the Siemens Synco™ living system and thank you for pur-
chasing the central apartment unit!
The present document describes how to mount and commission the central
apartment unit and the other system components.
First, please familiarize yourself with the operating philosophy of the central
apartment unit. Operation itself is covered by the operating instructions
(CE1B2740en).
Symbols used
The symbols used on the central apartment unit are explained in Section "Dis-
play symbols" in the operating instructions. The following symbols are used in
this document:
This symbol draws your attention to important information you must ob-
serve to ensure safe operation of the plant.
The info symbol refers to additional information, notes and practical tips
on settings and operation of the various units and the system.
This symbol refers to disposal issues.
Setting values and predefined settings
When commissioning the system, the activated parameters are loaded as
predefined settings. The documentation differentiates between guide values
and factory settings.
Guide value Setting recommended for most types of plant.
Factory setting Setting that can be changed to meet user- or plant-
specific requirements.

Safety notes
Product liability
•Use these products only in building services plant and only for the
applications described.
•Comply with all local safety regulations (installation, etc.).
•Do not open the devices. Opening the devices will void warranty by
Siemens.
•If a device is defective or damaged, disconnect it from power imme-
diately and replace it.
•Application-related technical data are only guaranteed in connection
with the Siemens Synco™ living system. When using together with
third-party products not specified by Siemens, user must ensure
functionality. In that case, Siemens does not provide any services or
warranty.

Building Technologies Mounting and installation 13.12.2010
Mounting and installation
Mount the central apartment unit
Mounting rules
•The central apartment unit is designed in compliance with safety class II
and must be mounted accordingly.
•Power may be applied to the unit only when completely mounted. Other-
wise, there is a risk of electric shock by the connection terminals.
•Do not expose the unit to dripping water.
•Adhere to the permissible ambient conditions as stated in the technical data
(see data sheets N2740en (QAX913) or N2741en (QAX903)).
•Sufficient space must be provided for fitting/removing the unit cover and for
connecting the service tool (>70 mm below and >10 mm above the unit).
Mounting location
The central apartment unit consists of electronics section and base.
The base is designed for wall mounting (on an interior wall of the apartment).
We recommend mounting the unit in an easily accessible space (e.g. in the
living room or the lobby). For convenient operation, the recommended mount-
ing height is 1.5 m above the floor.
2707Z31
> 70 mm > 10 mm
1.5 m
The central apartment unit communicates with most system components via
radio. To ensure optimum radio coverage, the following points should be ob-
served:
•The distance to devices with electromagnetic emissions, such as wireless
telephones, TV sets, PCs, microwave appliances, etc., should be at least
1 m.
•Larger items made of steel or construction elements with metal meshes
(e.g. special glass or concrete), or metal foils in thermal insulation materials,
mirrors or metal-coated heat absorbing glass, can have an impact on the
range.
•The typical range between transmitter and receiver in residential buildings is
30 m, or across 2 floors, or 2 concrete ceilings. But depending on the type

13 / 134
Siemens Synco™ living CE1C2740en
Building Technologies Mounting and installation 13.12.2010
of house or building and the materials used, the effective range can be con-
siderably greater or smaller.
If greater distances are to be covered, RF repeaters should be used.

Mounting procedure
Mounting method / knockout holes
The base of the central apartment unit can be mounted directly on the wall or
on a recessed conduit box. It has an opening at the rear and 2 knockout holes
(one at the top and one at the bottom). If required, the hole(s) must be
knocked out before securing the base to the wall.
Holes
Secure the base to the wall with at least 3 screws. To determine the positions
of the holes in the wall, hold the base horizontally against the wall and mark
the required positions.
Remove the electronics section from the base
Insert a screwdriver (size 3)
in the first and then in the
second slot at the bottom of
the unit, slightly push it and
then turn to unlock.

15 / 134
Siemens Synco™ living CE1C2740en
Building Technologies Mounting and installation 13.12.2010
Swing the electronics sec-
tion 45° upward and pull it
towards you to remove it.
Fit the base
Secure the base to the wall
using at least 3 fixing screws.
Wiring
Wiring is described under “Connection terminals/wiring“ (see page 16).
Replace the electronics section
Insert the electronics section
at an angle of about 45° in the
base (left and right). Then,
swing it downward until it en-
gages.
The central apartment unit is
now ready for commissioning.

Electrical installation of the
central apartment unit
Installation rules
•Comply with all local safety regulations (installation, etc.).
•Only qualified staff may carry out electrical installations.
•Prior to installation, disconnect the central apartment unit from power!
•The connection terminals for low-voltage and mains voltage are arranged
on different sides of the unit.
•When wiring the unit, satisfy requirements of safety class II.
•Provide cable strain relief.
Connection terminals/wiring
The connection terminals can be accessed from the front of the base.
Connect the low-voltage and mains voltage cables to the respective terminals
on the base.
Run the cables under the straps provided and – after connection – ensure
strain relief with the help of cable ties.

Building Technologies Commissioning the system 13.12.2010
Commissioning the system
Prerequisites
Prior to commissioning the system, check to ensure that the following prereq-
uisites are met:
•You are familiar with the different operating elements and operating levels
of the central apartment unit.
•All system components are correctly installed.
•Mains-powered components are connected to power.
•New batteries are ready to be inserted in the battery-powered devices *.
•Wired devices are connected to the KNX TP1 data bus.
•Meters are integrated correctly and connected to the consumption data in-
terface WRI982.
* To extend battery life, insert the batteries only prior to connecting the
device to the central apartment unit (for procedures, see the mount-
ing instructions of the associated device).
Procedure
Commission the system in steps:
1. Commission the meters (if available):
2. Enter the basic configuration for the central apartment unit.
3. Enter extra configurations for the central apartment unit.
4. Switch on and connect the devices communicating via radio (KNX RF).
5. Test the wiring.
6. Configure the wired bus communication (KNX TP1).
7. Set the central apartment unit parameters.
Basic configuration of the central apartment
unit
You must first enter the basic configuration at the central apartment unit to
connect devices.
Switch on the central apartment unit
The central apartment unit must be switched on to enter the basic configura-
tion.

Siemens Synco™ living CE1C2740en
Building Technologies Commissioning the system 13.12.2010
The unit switches on as soon as
power is supplied. A brief function test
is carried out while the hourglass is
displayed.
When you first commission the central apartment unit, you must select
the language, time of day, year, and date.
The display then changes to the default picture.
You can also select both language and time format during operation.
See the operating instructions for a description.
Tuesday 01:32 16.11.2010
If the central apartment unit was oper-
ated previously (e.g. after a power fail-
ure), the default picture appears after
the function test.
Change to the expert level
You must be at the expert level to enter the basic configuration.
Simultaneously press the Esc and Menu/ok button to
go from the default picture to the expert level. The
”Access levels“ window opens.
