WARNING
It is important to comply with the following
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 con-
trols 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 clean-
ing or other maintenance work must be performed.
Function of the sun shading actuator
You will find a detailed description of the software functions
for the KNX sun shading actuators in the manual (art. no.
2014788). 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 35-15).
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 termi-
nals, 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 in-
tended purpose specified in these instructions.
The sun shading actuator is intended for installation in
enclosed electrical operating facilities.
Safety instructions
WARNING
The electrical installation (assembly)/dis-
mantling must be performed by a certified
electrician in accordance with the electri-
cal installation regulations published by
the Association of German Electrical En-
gineers (VDE 0100) or the standards and
legal requirements of the country in which
the device is being installed. The electri-
cian must observe the installation instruc-
tions included with the supplied electrical
devices.
WARNING
If hazard-free operation cannot be as-
sumed, 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 operating
voltages have been applied, the device can be operated
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 pro-
gramming 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 within 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.
Cleaning
Clean the housing with a soft, dry cloth. Do not use deter-
gents, cleaning agents, solvents, abrasive substances or
steam cleaners!
Liability
In the event of failure to comply with the product informa-
tion contained in these instructions, or if the device is used
in any manner other than its designated or intended use,
the manufacturer may refuse to honour warranty claims
for product damage. In this case, liability for consequential
damage to persons or property will also be excluded.
Obligations for the disposal of electrical
devices
A marking with this symbol indicates the following
obligations under the scope of legal regulations:
 The owner of this electrical device must dispose of it
separately from unsorted municipal waste for further
recycling.
 Used batteries and accumulators that are not enclosed
in the old device, as well as lamps/bulbs that can be
removed from the old device without breaking, must be
disposed of separately.
 Distributors of electrical devices and disposal companies
are obliged to take back the equipment free of charge .
 The owner must take it upon themselves to delete any
personal data contained in the electrical device prior to
