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
transmitters may not get into the hands of
children!
OTICEN The receiver (e.g. the radio plug receiver,
radio tubular motor) cannot function in the
event of a power failure. Therefore, raise the
sun shading system early enough in case of
an approaching storm.
The radio control range is limited by legal regulations for
radio systems and by structural factors. Adequate radio
reception must be taken into consideration when planning
the system. This is particularly important when the radio
signal must pass 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).
 Therefore, check that the receiver is functioning
properly before the final installation.
Strong local transmitter systems (e.g. baby monitors or
neighbouring transmitters) can interfere with the reception.
Installation
This device is designed for surface mounting on a building
facade. It can also be mounted on a pole using the
included cable ties.
Included fixing materials:
2 screws 4.5 x 40 mm
2 dowels 6mm
2 spacers for wall and ceiling installation (Fig. 2)
2 steel cable ties 360 mm
Use suitable fixing materials only. Depending on the
substructure (e.g. plastered outer insulation), other screws
and dowels may need to be used.
Important information on the installation location
 Attach the device outdoors at a readily accessible but
raised location.
 Metal-clad buildings, domestic interference sources
(unshielded household appliances, television sets,
computers), supply lines and metallic objects such
as sheet metal enclosures must have a distance of at
least 0.5 m from the weather station.
 Install the device in a position in which the wind
wheel is horizontal (housing inclination of 15°). When
installing the device on sloped surfaces, the sensor
can be positioned horizontally using the joint (Fig. 1).

solar powered. The device sends move commands to
EWFS-compatible receivers.
Intended use
The EWFS Weather station is an electronic device
to control sun shading systems. The approval of the
manufacturer must be obtained for uses outside of the
purposes listed in these instructions.
Safety instructions
ARNINGW
An automatically controlled mechanism

 When selecting the installation location, ensure that the
solar panel is sufficiently supplied with sunlight. For
example, an overhanging roof may shade the panel at
certain times of the day. Also avoid installing it on the
north face of buildings.
 Before installing the device, consider that trees, bushes
or parts of the building may shade the photo sensor
during the course of the day. In this case, the sensor
cannot deliver exact values and the results will be
incorrect. Therefore, select the installation location
carefully.
 When selecting an installation location, ensure that
the photo sensor is exposed to the same brightness
conditions as the sun shading product being
controlled. This means that you need to position the
photo diodes according to the building facades being
shaded. Ideally, the weather station is oriented in the
same direction as the sun shading product being
controlled.
 Mount the device in the vicinity of the sun shading
product although not in places where the sun shading
product affects the wind currents; otherwise, the sensor
will not provide correct wind readings.
 Separate spacers are included for wall and ceiling
installation. They prevent cracking and deformation of
the plastic (Fig. 2).
Fig. 2 Clipping the separate spacers into the threaded hole

Fig. 8 USB connection of the weather station
As an exception: commission without USB
If the power supply is not possible via USB, you can
also proceed as follows. However, if the product is not
commissioned swiftly, the energy stored in it up to that
point may not be sufficient to complete commissioning.
 After installation, the weather station must be exposed
to daylight for at least 30minutes.
 Then press the button for at least 5 seconds.
The status LED lights up green once. The device is
now switched on and ready for operation.
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".
Power-up: To learn in a receiver, you must
de-energize a receiver or group of receivers,
either at the in-line circuit breaker or at the
associated plug-in connector, and then
switch it back on again after approx. 5
seconds. (Power-up procedure). Always
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 training key on the
transmitter must be pushed within this period
or the learning mode is closed. Push the the
training key on your transmitter whenever
you see the symbol of the training key.
Wave: After the learn button on the
transmitter is activated, the connected
sun shading system carries out several
movements. In these instruction, 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
immediately.

Learning in the weather station
The weather station sends wind- or brightness-related
move commands to an EWFS receiver. It must be learned
into the receiver first.
OTICEN The weather station must be charged before
commissioning to enable fault-free operation
(see Commissioning). The weather station can
only be learned in as an auxiliary channel.
Example: You would like to operate an external venetian
blind with a 1-channel hand-held transmitter (I) and control
it with the weather station based on brightness and wind
values.

Ι
= Master channel = Auxiliary channel
Fig. 9 Controlling a external venetian blind with a hand-held
transmitter (I) and a weather station.
 Perform the following steps consecutively:
Place receiver1 into learn
mode: Perform the power-
up procedure on external
venetian blind1.
Learn in the hand-held
transmitter (I) as the master
channel: Take the hand-held
transmitter (I), press and hold
the learn button, the external
venetian blind1 waves once,
release the button.
The learn mode is ended
automatically. The hand-held
transmitter (I) is now the
master channel for external
venetian blind1.
External venetian blind1 can now be operated with the
hand-held transmitter (I).
 Now learn the weather station into the receiver as an
auxiliary channel:
For this function, the wind
speed limit may not be set to
TEST and the brightness limit
value may not be set to OFF
at the weather station.
Place receiver1 into learn
mode: Take the hand-held
transmitter into which the
master channel was just
learned (I), press and hold
the learn button, external
venetian blind1 waves once,
release the button.
Ι
Ι
Learn in the weather station
as an auxiliary channel:
Press the button on the
weather station and hold it
until the sun shading system
stops moving (the external
venetian blind waves twice).
Release the button. The
weather station is now an
auxiliary channel for external
venetian blind1. The wind
and brightness evaluation
was learned in at the same
time.
End the learn mode: Take
the hand-held transmitter with
the master channel (I) and
press the "Up" or "Down"
button.
External venetian blind1 now can also be controlled
with the weather station.
The weather station evaluates the brightness and
wind speed data and controls the sun shading system
accordingly.
Testing the weather station
Perform the following steps to test the functions of the
weather station.
In the previously described learning procedure, the wind,
precipitation and photo sensors were learned in together.
If you discover during the test that one of the sensors was
not learned in (e.g. due to electromagnetic interference), it
must be learned in again separately.
OTICEN If a sensor that has already been learned in is
learned in again, it is learned out.
Example: During the learning procedure, only
the wind sensor was learned in. If the learning
procedure is repeated, the photo sensor is
learned in but the wind sensors is learned out
at the same time.
1. Test the wind monitoring function
 Move the "Wind" switch on the weather station to the
TEST position. Move the sun shading system down
slightly and cause the wind wheel to turn rapidly. The
sun shading system should now move up as a wind
alarm is triggered. The sun shading system now cannot
be operated for the duration of approx. 1minute (wind
alarm).
OTICEN In the TEST position, the duration of the wind
alarm is only approx. one minute, after which
the system can be operated again. For all other
settings (see the adjacent limit value table) a
wind alarm takes approximately 10minutes.
The TEST setting should not remain set during
normal operation since the weather station
otherwise continuously sends a wind alarm
(high power consumption).
Ι

890463_k•en•2019-10-01 We reserve the right to carry out improvements
If the sun shading system does not move up, the wind
sensor may not have been learned. To test whether the
wind sensor was correctly learned into the receiver:
 Move the "Wind" switch on the weather station to any
position other than TEST. Move the "Brightness" switch
to OFF. Lower the sun shading system slightly and
press the button on the weather station.
 If wind monitoring has been learned in correctly, the
sun shading system moves down for approx. one
second.
If the sun shading system does not move during this
test, wind monitoring was not learned in. Learn in wind
monitoring again separately (see „Learning in functions
individually“).
OTICEN In this test, EWFS tubular motors do not
respond when the button is pressed.
2. Test the sun control
 Move the sun shading system manually to its middle
position.
 Move the "Wind" switch on the weather station to the
TEST position and the "Brightness" switch to position
"1".
 Trigger a wind alarm: Cause the wind wheel to turn
quickly and hold on to the wheel as soon as the sun
shading system moves out.
 After 1 or 2 minutes the sun shading system must
move down again.
If the sun shading system does not move down, the photo
sensor may not have been learned. To test whether the
photo sensor was learned into the receiver correctly:
 Move the "Brightness" switch on the weather station to
any position other than "OFF". Move the sun shading
system down slightly and press the button on the
weather station.
 If the sun control was learned in correctly, the sun
shading system moves down for approx. one second.
If the sun shading system does not move during this test,
the sun control was not learned in. Learn in the sun control
again separately (see „Learning in functions individually“).
OTICEN In this test, EWFS tubular motors do not
respond when the button is pressed.
Learning in functions individually
If problems arose when learning in the weather station of a
sun shading product, the functions can be learned into the
sun shading product separately later on.
Learning the wind monitoring function individually
 Perform the following steps consecutively:
Place receiver1 into learn
mode: Take the hand-held
transmitter into which the
master channel was learned
(I), press and hold the learn
button, external roller blind1
waves once, release the

automatically.
To reactivate the sun control with the Abutton:
 Press and hold the Abutton. Release the button again
when the sun shading system waves.
The sun control is active again.
OTICEN The sun control can be switched off temporarily
with the master channel or with the auxiliary
channels.
Switching the sun control on/off permanently
 Set the switch for the sun control on the weather
station to OFF.
The weather station stops sending brightness-related
move commands.
 Set the switch for the sun control on the weather
station to the previous value to switch the sun control
back on.
Cleaning
 Photo sensors or solar panels must always be clean
to avoid incorrect measuring values and to ensure
operating reliability. The device should occasionally be
checked for soiling (e.g. bird droppings) and cleaned
carefully. Standard household cleaners may be used.
Do not use solvents.
 In snowfall, check daily that the solar panel and
photodiodes are free of snow. A snow-covered weather
station may fail to function properly. If the energy in the
buffer is depleted, the weather station fails completely.
It resumes normal operation after it is recharged via
the solar panel.
 The weather station may ice over and the wind wheel
may freeze up in extreme weather conditions. To avoid
wind damage, take your sun shading system out of
operation until wind monitoring can be resumed.
 Never remove firmly attached layers of ice and snow.
Scratching, heat and chemical antifreeze agents may
damage the weather station.
Maintenance
There are no parts within the device that require
maintenance.
Strong vibrations at the installation location (for example,
from frequent high wind loads) can loosen the fixing
screws. If the joint screw is not properly tightened, the
orientation of the weather station may change as well.
 Therefore, check from time to time that the weather
station is still firmly installed and that all screws are
sufficiently tight.
Liability
Failure to comply with the product information in these
instructions and use of the device in a manner that
contravenes its intended use and purpose may result in
the manufacture refusing to honour warranty claims for
product damage. In this case, liability for consequential
harm to persons or damage to property will also be
excluded. Follow also the instructions in the operating
manual of your sun shading system. The automatic or
manual operation of the sun shading system when iced
over as well as using the sun shading system during
severe weather may cause damages and must be
prevented by the user by taking suitable precautions.
OTICEN The device meets the requirements on
interference resistance and interference
emission for use in residential and commercial
areas.
Disposal
After its use, the device must be disposed off according to
legal regulations or returned to your local recycling centre!
Heartbeat function

7
890463_k•en•2019-10-01 We reserve the right to carry out improvements
The weather station cyclically sends a so-called "heartbeat
pulse" to all receivers into which it is learned.
If the receiver does not receive measuring values for 24h,
it is assumed that the weather station has failed (heartbeat
function). The receiver moves the connected product to
a safe position. Depending on the type of sun shading
product, operation is limited or impossible until a new valid
value is received. 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).
