WARNING
It is important to comply with the fol-
lowing points in the interest of personal
safety.
Children may not play with the operating elements of
the control unit or the remote control. Store remote
controls out of reach of children.
Make sure that no persons or objects are in the range
of movement of the driven parts (blinds, external vene-
tian blinds, etc.).
Disconnect the device from the supply voltage if
cleaning or other maintenance work must be perfor-
med.
Function of the sun shading actuator
You will find a detailed description of the software func-
tions for the KNX sun shading actuators in the manual
(art. no. 2014 788). You can download the manual and
the product database of the sun shading actuator from
www.warema.com.
Installation
The device is intended for installation in a distribution
cabinet. The device is mounted by clipping it onto a DIN
rail (TH 35/DIN 60715).
Electrical connection
An on-site overload current protection device (fuse) and a
disconnecting and isolating switch to switch off the entire
system must be provided.
The electrical connection is made as shown in the wiring
diagram on the reverse side (Fig. 4), the connection to
the KNX bus system and the drives is made using spring
terminals, the connecting lines are designed as screw
terminals.
General information
Fig. 1 KNXSA4MDC REG
The KNXSA4MDCREG sun shading actuator is a device
for the central operation of up to four sun shading drives
24 V DC.
The device is operated using a KNX bus system. The sun
shading actuator and the drives are supplied with 24 V
DC.
Intended use
The KNXSA4MDCREG was developed to control sun
shading products. The approval of the manufacturer
must be obtained for any use of the device other than its
intended purpose specified in these instructions.
The sun shading actuator is intended for installation in
enclosed electrical operating facilities.
Safety instructions
WARNING
The electrical installation must be per-
formed by a certified electrician in ac-
cordance with the electrical installation
regulations published by the Association
of German Electrical Engineers (VDE
0100) or the standards and legal require-
ments of the country in which the device
is being installed. The electrician must
observe the installation instructions inclu-
ded with the supplied electrical devices.
WARNING
If hazard-free operation cannot be assu-
med, the device may not be started or
must be deactivated. This assumption is
justified if:
 the housing or the connecting lines show
signs of damage,
 the device is no longer working.

Commissioning
After the installation has been completed and the operat-
ing voltages have been applied, the device can be oper-
ated using a keypad (Fig. 2).
You will find a detailed description on the further commis-
sioning in the KNX manual (art. no. 2014 787).
Local operation
The keypad has 4 buttons, the Up / Down / Select and
Prog buttons, and an LED. The Select button is used to se-
lect the channel. The selected channel is displayed by one
of the 4channel LEDs. If the SEL button is pressed again
after selecting channel4, all channels are selected.
Fig. 2 Keypad
Local operation on the device has the same priority as
manual operation via communication objects. The operat-
ing behaviour is the same as the "KNX behaviour":
Brief push of the button = Step / Stop,
Long push of the button = Move.
WARNING
Never randomly press the buttons on the
keypad without having a line of sight to
the sun shading system.
Programming
Press the programming button (Fig. 2) to
put the device into programming mode. The
LED lights up red when programming mode
is active. The device is programmed on a
PC using the ETS. This software ends the
programming mode automatically. The red
LED goes out.
If the programming mode is to be ended
earlier, press the programming button again.
The red LED goes out.
Maintenance
There are no parts inside the device that require mainte-
nance. In the event of a malfunction, the built-in miniature
fuses should only be changed by a certified electrician.
Liability
Failure to comply with the product information in these in-
structions and any use of the device other than its intend-
ed use may result in the manufacturer refusing to honour
warranty claims for product damage. In this case, liability
for consequential damage to persons or property will also
be excluded. Observe the information in the operating
instructions for your sun shading system. The automatic
or manual operation of the sun shading system while iced
over as well as using the sun shading system during se-
vere weather may cause damage and must be prevented
by the user through suitable precautions.
Disposal
After use, the device must be disposed of according to
legal regulations or turned in to your local recycling centre.
