General information
Fig. 1 KNXEWFS Receiver
The KNX EWFS Receiver serves as a gateway between
the Standardised WAREMA Radio System (EWFS) and the
KNX protocol.
The KNX EWFS Receiver is a radio receiver for WAREMA
EWFS Hand-held transmitters, EWFS Wall-mounted
transmitters, EWFS Timers and EWFS Weather stations.
A maximum of 8 EWFS hand-held transmitters can be
managed per device, i.e. either 8 x EWFS hand-held
transmitters1K or 4 x EWFS hand-held transmitters1K
and 4 x EWFS hand-held transmitters8K. The transmitters
are differentiated by their transmitter address. The
commands sent by an EWFS transmitter/channel can then
be executed in KNX telegrams. The following data types
are available for this purpose:
Stop/step command 1 bit
UP/DOWN move command 1 bit
Switch ON/OFF, changeover 1 bit
Value 1 byte
Scene 1 byte
The product data base can be downloaded from the
Internet under http://www.warema.de.
The parameters are set via the parameter dialogue box of
the ETS3 or a newer version.
The central operation is implemented by coupling to a KNX
twisted pair network via the integrated KNX transceiver.
Power is supplied via the KNX network. A separate power
supply is not needed. Spring contacts for the looping of
the bus line are available.
These operating and installation instructions are ad-
dressed to everyone planning and installing a KNX EWFS
Receiver within a KNX twisted pair network.
nObserve the technical data and comply with the wiring
conditions. These instructions contain the necessary
information.
nAny other use is considered improper.
Because of its compact design, the receiver can be in-
stalled in a flush-mounted junction box.
Intended use
The KNX EWFS receiver is an electronic device developed
to control sun shading systems. The approval of the manu-
facturer must be obtained for uses outside of the purposes
listed in these instructions.
Safety instructions
ARNINGW
The electrical installation (assembly)/dis-
mantling must be performed by a certified
electrician in accordance with VDE 0100
and/or with the standards and legal require-
ments of the country in which the device is
being installed. The electrician must observe
the installation instructions included with
the electrical devices supplied.
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 must not play with
this product – remote controls or transmit-
ters must not get into the hands of children!
Do not expose the KNX EWFS Receiver to
excessive heat or humidity.
Do not introduce foreign objects into the housing.
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 KNX EWFS Receiver should
not be installed in the immediate vicinity of metal compo-
nents (steel beams, steel-reinforced concrete, fire door).
nMount the device in a central location, as far as possi-
ble from influences that are detrimental to radio recep-
tion.
nNote the following when aligning the aerial:
Arrange the aerial in a stretched position; do not fold
or roll up.
Keep as far away from metal parts as possible.
Do not position the aerial in the vicinity of or parallel
to electrical lines.
nCheck 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
The receiver is intended for installation in a flush-mounted
junction box. Only lines used for wiring the receiver should
be routed into this box. The unit is electrically connected
according to the adjacent wiring diagram (see Fig.2).
The lines are connected using plug-in terminals.

Programming
For commissioning, the device is equipped with a pro-
gramming button and a red status LED.
nPress the programming button to put the device into
programming mode. The red LED lights up when pro-
gramming mode is active. The device is programmed
on a PC with the corresponding software. The software
ends the programming mode automatically and the red
LED goes out.
nIf you wish to end the programming mode prematurely,
press the programming button again. The red LED
goes out.
For commissioning, you need the EWFS Receiver
and the WAREMA EWFS Monitor software. The
WAREMA EWFS Monitor can be downloaded from
www.warema.de.
Operation
The KNX EWFS Receiver is operated with trained EWFS
Hand-held transmitters or EWFS Wall-mounted transmitters.
Please refer to the KNX EWFS Receiver software documen-
tation for the exact programming and operating procedure.
Function
A detailed description of the functions is provided in the
software documentation of the control system.
Heartbeat function for a learned EWFS Weather station
The weather station cyclically sends a so-called "heartbeat
pulse" to all receivers into which the weather station is
learned. Unfavourable conditions (eco weather station:
longer periods of darkness or soiling of the solar panel;
plus weather station: power failure) may cause the weather
station to fail temporarily. In this case, the weather station
does not emit heartbeat pulses. The receiver may also
fail to receive a heartbeat pulse from a learned weather
station when the installation situation is unfavourable.
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.
Maintenance
There are no parts within the device that require
maintenance.
Please consult your system integrator if operating
problems arise.
Contact your WAREMA dealer if repair is required.
Cleaning
Clean the housing with a soft, dry cloth. Do not use deter-
gents, cleaning agents, solvents, abrasive substances or
steam cleaners!
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 manufacturer 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 damage and must be
prevented by the user by taking suitable precautions.
Disposal
After use, the device must be disposed of according to
legal regulations or turned in to your local recycling centre.
