General information
Fig. 1 EWFS Uniswitch
The EWFS Uniswitch radio receiver is an electronic control
unit for the direct control of any motor control unit and can
receive move commands from EWFS-compatible transmit-
ters. The EWFS Uniswitch works in dead man's mode and
has floating switch contacts. In this way, the receiver can
easily be connected in parallel to an existing push button.
The movement behaviour of the connected motor control
unit remains unchanged. The receiver is supplied with 24
V DC either via an existing control line, a floor distribution
control or a power supply unit. Because of its compact
design, the receiver can be installed in a flush-mounted
junction box.
Intended use
The EWFS Uniswitch radio receiver was developed to
control sun shading systems. The approval of the manu-
facturer must be obtained for uses outside of the purpos-
es listed in these instructions.
Safety instructions
ARNINGW
The electrical installation must be per-
formed by a certified electrician in
accordance with the electrical installation
regulations published by the Associa-
tion of German Electrical Engineers (VDE
0100) or the standards and regulations of
the country in which the device is being
installed. The electrician must observe the
installation instructions included with the
electrical device.
ARNINGW
If hazard-free operation cannot be
assumed, the device may not be started or
must be deactivated. This assumption is
justified if
the housing or the supply lines show
signs of damage
the device is no longer working.
AUTIONC
Never activate buttons on your transmitter
arbitrarily without visual contact to the sun
shading product. Children may not play with
this product - Remote controls or transmit-
ters must not get into the hands of children!
The range of radio controls is restricted by legal regulations
for radio systems and through structural factors. Adequate
radio reception must be ensured when planning the project.
This applies especially if the radio signal must penetrate
through walls and ceilings. The control unit should not be
installed in the immediate vicinity of metal components
(steel beams, steel-reinforced concrete, fire door).
nTherefore, check that the receiver is functioning prop-
erly before the final installation.
Strong local transmitter systems (e.g. baby monitors or
neighbouring transmitters) can interfere with the reception.
Function
After the "Up" or "Down" button is pressed on the hand-
held transmitter, the sun shading system moves in the
corresponding direction. The movement behaviour of the
motor control unit is retained. Read the operating instruc-
tions of the connected motor control unit.
Central operation
The local operation is blocked for the duration of a central
command; any current move commands will be deleted.
Symbols used
When the receiver is delivered, it does not "know" any
transmitters initially and first needs to learn to which
transmitters it should respond. We refer to this process as
"learning".

Explanation of symbols:
Power-up: To learn, you must electrically isolate
a receiver or a group of receivers, either at the
in-line circuit breaker or at the associated plug-
in connector, and then reconnect it again after
approx. 5 seconds. (Power-up procedure). Al-
ways carry out a power-up procedure when you
see the symbol of the circuit breaker.
The receiver is now in learn mode for approx.
one minute. The learn button on the transmitter
must be pushed within this period or the learn
mode is closed. Push the learn button on your
transmitter whenever you see the learn button
symbol.
Wave: After the learn button on the transmitter
is activated, the connected sun shading system
carries out several movements. In these instruc-
tion, we use the adjacent symbol for waving.
Waving once: Press the learn button on the
transmitter, wait until the connected sun shading
system moves and then release the button im-
mediately.
Learning in the master channel
You can either learn in a 1-channel transmitter or one
channel of an 8-channel transmitter in a receiver as the
master channel. With an 8-channel transmitter, you only
need to make sure that you first select the desired chan-
nel, as the following example shows:
How to learn channel 1 of an 8-channel hand-
held transmitter into a receiver:
Place the receiver into
learn mode: Perform the
power-up procedure on the
receiver.
Learn in the transmitter:
Take the transmitter, select
channel 1, push and hold
the learn button, the sun
shading waves once, re-
lease the button.
Result: You can now operate the receiver with channel
1 of the transmitter.
Forming a group
You would like to operate two external venetian blinds with
an 8-channel hand-held transmitter (I) as follows:
Channel1 controls external venetian blind1 (master channel)
Channel2 controls external venetian blind2 (master channel)
Channel3 controls both external venetian blinds together
(auxiliary channel)

Fig. 2 Building a group

Ι
1st step: Learn in the master channel
One master channel must be learned into each receiver
before you can form a group. As described in the section
"Learning in the master channel", learn in channel 1 on
receiver 1 as a master channel and channel 2 on receiver
2 as a master channel.
OTICEN If this is not possible because the power-up pro-
cedure cannot be performed separately for the
receivers, the master channels must be learned
in by means of "patent learning". Information
on this procedure can be found in the "EWFS
application brochure" at http://www.warema.
de → Produkte → Steuerungssysteme →
Funksysteme.
2nd step: Learn in the auxiliary channel
You can now operate the external venetian blinds sepa-
rately, and each learned channel is a master channel in
the respective receiver. If the learn button is pushed with
this master channel, the learn mode can be started and
an auxiliary channel learned into the respective receiver
even without the power-up procedure. If the same auxiliary
channel, e.g. channel 3, is now learned into each receiver,
both external venetian blinds can later be operated as a
group with channel 3 but they can still be operated sepa-
rately via the master channels 1 and 2. The next step is to
learn the auxiliary channels:
Learning channel 3 into external venetian blind 1
Place receiver1 into
learn mode: Select chan-
nel1, press and hold the
learn button, external vene-
tian blind 1 waves once,
release the button.
Learn channel3 as an
auxiliary channel: Select
channel3. Press and hold
the learn button, external
venetian blind1 waves
once, release the button.
Channel3 is now an aux-
iliary channel for external
venetian blind1.
End the learn mode: Se-
lect channel1 and press
the "Up" or "Down" button.
Result: External venetian blind1 now can also be oper-
ated with channel3.
Learning channel 3 into external venetian blind 2
Place receiver2 into
learn mode: Select chan-
nel2, press and hold the
learn button, external vene-
tian blind 2 waves once,
release the button.
Learn channel3 as an
auxiliary channel: Select
channel3, press and hold
the learn button, external
venetian blind2 waves
once, release the button.
Channel3 is now an aux-
iliary channel for external
venetian blind2.

Result: External venetian blind2 now can also be oper-
ated with channel3.
Deleting an auxiliary channel
You can delete all auxiliary channels learned into the
receiver if you have committed an error and you want to
start over again. Note the following example:

= Master channel = Auxiliary channel
Fig. 3 Auxiliary channels in receiver 1 and 2 are to be deleted.
n Carry out the following operation steps consecutively
with the respective master channel:
Delete all auxiliary chan-
nels in receiver 1: Select
master channel 1, push
the learn button and hold
it for at least 20 seconds
until the external venetian
blind no longer carries out
any movement!
End the procedure: Select
channel1 and press the
"Up" or "Down" button.
Delete all auxiliary chan-
nels in receiver 2: Select
channel 2, push the learn
button and hold it for at
least 20 seconds until the
external venetian blind
no longer carries out any
movement!
End the procedure: Se-
lect master channel 2 and
push the "Up" or "Down"
button.
Result: All auxiliary channels in receiver 1 and receiver
2 were deleted.
OTICEN Only one master channel and 15 auxiliary
channels can be learned into each receiver.
The master channel cannot be deleted but can
only be overwritten with a new channel. The
auxiliary channels are not deleted when you
learn in a new master channel. The weather sta-
tion can be learned in as an auxiliary channel.
Heartbeat function
When a weather station is learned into the device, the
heartbeat function becomes active. The weather station cy-
clically sends a so-called "heartbeat pulse" to all receivers
into which the weather station was learned. If the power
supply of the weather station fails, for example, the station
does not send a heartbeat. The receiver may also fail to
receive a heartbeat pulse from a learned weather station

when the installation situation is unfavourable. If a heart-
beat signal does fail to arrive for 24 h, this is considered
by the receiver to be a weather station failure and the sun
shading system is raised for safety reasons. In this phase,
the sun shading system cannot be operated as usual:
When it is lowered manually, the movement is stopped
automatically after approx. 5seconds. Pressing the button
again causes the same reaction. The sun shading system
can be raised as usual. This is a safety function and not
an error.
AUTIONC
If you force the sun shading system to move
down by repeatedly activating the DOWN
button when the weather station has failed,
the safety functions are not active. The sun
shading system may become damaged (e.g.
due to high winds).
Special functions
Manifold special functions are additionally possible in
WAREMA EWFS. Should you wish further information, your
specialist dealer will be pleased to give you the applica-
tion brochure.
The "A", "B" and "C" function buttons
Function button "A" of the transmitter can be used to
switched off the sun control temporarily if you additionally
use an EWFS weather station in your system.
Temporary deactivation of the sun control:
nPress the "A" button of the transmitter and hold until
the sun shading system stops moving. Release the but-
ton again. The sun control is now switched off for 12
hours. After this period, the sun control is reactivated
again automatically.
Activate the sun control again:
nPress and hold the "A" button of the transmitter. Re-
lease the button again when the sun shading system
waves. The sun control is active again. If the automatic
system was already active, nothing changes.
The "A", "B" and "C" buttons of this transmitter have no
function.
Installation
The receiver is designed for installation in a flush-mounted
junction box 80 x 80 mm. Only lines used for the wiring
of the receiver should be routed into this box. The unit is
electrically connected according to the wiring diagram on
the reverse. The lines are connected via spring terminals.
Electrical installation
An on-site overload current disconnecting and isolating
switch to switch off the entire system must be provided.
