SDW 10
WALL MODULE
MOUNTING AND OPERATING INSTRUCTIONS
GENERAL
The SDW 10 Wall Module can be used for the remote
control of a connected heating circuit. The SDW 10
features the following functions:
•registering the current ambient temperature
(room sensor);
•switching between operating modes
(automatic operation / heating / cooling);
•adjusting the current temperature setpoint
(desired daytime setpoint / setback temperature
setpoint).

Registering the Current Ambient Temperature
The SDW 10's integrated room sensor registers the current
ambient temperature. The resultant value is then employed
for all room temperature-based functions and is also
transmitted to the central system via a double-wire data
bus cable.
Adjusting the Current Temperature Setpoint
Using the temperature setpoint adjustment knob (see Fig.
1), the daytime room temperature setpoint and/or setback
temperature setpoint (defined at the central controller) can
be adjusted by max. ±6 K.
•Rotating the temperature setpoint adjustment knob
clockwise (i.e. towards the symbol) raises the
temperature setpoint.
•Rotating the temperature setpoint adjustment knob
counterclockwise (i.e. towards the symbol) lowers
the temperature setpoint.
Switching between Operating Modes
Using the operating mode button (see Fig. 1), the SDW 10
can be switched from one operating mode to another. This
is done by pushing and holding down the operating mode
button until the desired operating mode is reached (as
indicated by the corresponding LED). It is possible to
switch between the following three operating modes:
The Automatic Operating Mode ( )
In this operating mode, the heating circuit is continuously
controlled in accordance with the programmed time
schedule (P1, P2, or P3) defined at the central controller,
and the temperature setpoint adjustment knob's setting is
taken into account.
The Continuous Heat Operating Mode ( )
In this operating mode, the heating circuit is continuously
controlled in accordance with the daytime room tem-
perature setpoint defined at the central controller, and the
temperature setpoint adjustment knob's setting is taken
into account.
The Continuous Setback Operating Mode ( )
In this operating mode, the heating circuit is continuously
controlled in accordance with the setback temperature
setpoint defined at the central controller, and the
temperature setpoint adjustment knob's setting is taken
into account.
NOTE: The setback temperature setpoint is defined for a
specific heating circuit at the central controller via
the parameter SETBACK OPERATING MODE. It
determines the heating circuit's behavior when in
the continuous setback operating mode. See also
the central controller's Operating Instructions.
Temporary Operating Modes
Temporary operating modes such as PARTY, ABSENT,
and HOLIDAY are indicated as follows:
PARTY: LED flashes ON and OFF continuously.
ABSENT: LED flashes ON and OFF continuously.
HOLIDAY: LED flashes ON and OFF continuously.
Bus Address
In order to restrict communication between the SDW 10
and the central controller to the given heating circuit, each
SDW 10 must be configured to the dedicated heating
circuit. In doing so, an appropriate bus address must be
set. This is done using the rotary HEX code switch (Fig. 2)
accessible after removing the front panel. The bus address
is assigned in accordance with Table 1.

IMPORTANT
The assignment of the same bus address to
more than a single SDW 10 will result in
interference during data transmission and thus
controller malfunction.
Incorrect bus address assignment is indicated when
powering up the SDW 10 as follows.
LED: Flashes ON and OFF continuously.
LED and LED: Are lit continuously.
MOUNTING INSTRUCTIONS
Mounting Location
The SDW 10 should be mounted at a location approx. 1.2
to 1.5 meters above floor level at a neutral site
representative, with regards to temperature, for all rooms.
The optimal location is a partition of a room with the
coolest daytime temperature.
The SDW 10 must not be mounted
•at locations exposed to direct sunlight (seasonal
variations should be taken into account);
•close to heat-producing appliances (e.g. televisions,
refrigerators, radiators, etc.);
•on walls heated by under-plaster heating pipes or
chimneys;
•on outside walls;
•in corners behind curtains or shelves (due to
insufficient ventilation);
•close to doors of unheated rooms (due to the influence
of low temperatures);
•on unsealed under-plaster wiring boxes.
Mounting
After removing the front panel, the SDW 10 can be
mounted at the desired location using the accompanying
screws and dowel pins. The cable for the bus connection
must be led through the hole at the bottom of the housing.
Electrical Connection
Electrical connection is effected at the two connection
terminals. Recommended cable: J-Y (ST) Y 2x2x0.6 mm2.
IMPORTANT
Do not reverse the polarity of terminals A and B!
After connecting the data bus cable and selecting the bus
address (see Table 1), replace the front panel.
