We congratulate you …
… on the selection of the Siemens Synco 900 system and thank you
for purchasing the central apartment unit!
The present document describes how to mount and commission the
central apartment unit and the other system components.
First, please ensure that you become familiar with the operating phi-
losophy of the central apartment unit. Operation itself is covered by
the Operating Instructions (B2707en).
Symbols
The following symbols are used in this document:
The “caution“ symbol marks important information that you
must observe to ensure safe operation of plant.
The “info“ symbol refers to special information, notes and
practical tips relating to settings and operation of the central
apartment unit and the system.
This symbol refers to disposal notes.
Setting values and predefined values
When commissioning the system, the parameters activated use pre-

Safety notes
Product liability
•Use the products only in building services plants and
only for the applications described.
•Comply with all local safety regulations (installation,
etc.)
•Do not open the devices. Non-adherence will void
any warranty offered by Siemens.
•If a device is defective or damaged, immediately dis-
connect it from power and replace it.
•Application-related technical data are only guaran-
teed in connection with the Siemens Synco 900 sys-
tem. When using products of other manufacture not
specified by Siemens, user must ensure functionality.
Siemens neither renders any services nor provides
any warranty for these cases.

Mounting and installation
Mounting the central apartment unit
Mounting regulations
•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. Otherwise, there is a risk of electric shock by the
connection terminals.
•The unit must not be exposed to dripping water.
•The permissible environmental conditions specified in the
technical data must be observed (refer to Data Sheet
N2707en).
•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 to mount the unit in an easily accessible
space (e.g. in the living room or the lobby). For convenient operation,
the recommended mounting height is 1.5 m above the floor.
2707Z31
> 70 mm > 10 mm
1.5 m
The central apartment unit communicates with most system compo-
nents via radio. To ensure optimum radio coverage, the following
points should be observed:
•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 me-
tal 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

9/88
Siemens Synco 900 CE1C2707en
Building Technologies Mounting and installation 05.07.2007
•The typical range between transmitter and receiver in resi-
dential buildings is 30 m, or across 2 floors, or 2 concrete
ceilings. But depending on the type of house or building and
the materials used, the effective range can be considerably
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
The base must be secured to the wall with at least 3 screws. To de-
termine the positions of the holes in the wall, hold the base horizon-
tally against the wall and mark the required positions.

11/88
Siemens Synco 900 CE1C2707en
Building Technologies Mounting and installation 05.07.2007
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.
Swing the electronics
section 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“ (refer to
page 12).

12/88
Siemens Synco 900 CE1C2707en
Building Technologies Mounting and installation 05.07.2007
Replace the electronics section
Insert the electronics sec-
tion at an angle of about 45°
in the base (left and right).
Then, swing it downward
until it engages.
The central apartment unit
is now ready for commis-
sioning.
Electrical installation of the
central apartment unit
Installation regulations
•Comply with local 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
INSIGHT.
•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.

Commissioning the system
Prerequisites
Prior to commissioning the system, check to ensure that the following
prerequisites 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 readily available to be inserted in the
battery-powered devices *.
•Wire-bound devices are connected to the KNX TP1 data bus.
* To extend battery life, insert the batteries only just before
connecting the device to the central apartment unit (for
procedure, refer to the Mounting Instructions of the relevant
device).
Procedure
The system should be commissioned in steps:
1. Make the basic configuration of the central apartment unit.
2. Switch on and connect the devices communicating via radio
(KNX RF).
3. Make the wiring test.
4. Configure the wire-bound bus communication (KNX TP1).
5. Set the parameters of the central apartment unit.
Basic configuration of the central
apartment unit
To connect the devices, the basic configuration of the central apart-
ment unit must be made first.
Switch on the central apartment unit
To be able to make the basic configuration of the central apartment
unit, it must be switched on.
The unit is switched as soon as
power is applied to it. During the
period of time the hour glass is
displayed, a short function test is
made.

15/88
Siemens Synco 900 CE1C2707en
Building Technologies Commissioning the system 05.07.2007
When the central apartment unit is commissioned for the first
time, you are prompted to select the language you require, and
to set the time of day, the year, and the date.
Then, the display changes to the default picture.
The language and the time format can also be selected during
operation. For description, refer to the Operating Instructions.
Tuesday 01:32 14.02.2006
If the central apartment unit was
in operation before (e.g. after a
power failure), the default picture
appears after the function test.
Change to the expert level
To be able to make the basic configuration, you need to be on the
expert level.
To go from the default picture to the expert
level, press simultaneously the Esc and the
Menu/ok button. Window ”Access levels“
opens.

Configure DHW charging
2707Z30
If you want DHW charging con-
trolled directly by the central apart-
ment unit, activate the required
DHW plant components (DHW
sensor, pump / valve, electric
immersion heater).
If you require external DHW
heating controlled remotely via
KNX TP1, activate ”Operation
external DHW“.
The type of DHW heating depends on the installed DHW components
according to the following table:
