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
UP/DOWN move command
Switch ON/OFF, changeover
Value
Scene
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.
Observe the technical data and comply with the wiring
n
conditions. These instructions contain the necessary
information.
Any other use is considered improper.
n
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.

The range of radio controls is restricted by legal regulations

for radio systems and through structural factors. Adequate
1 byte
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).
Mount the device in a central location, as far as possi-
n
ble from influences that are detrimental to radio recep-
tion.
Note the following when aligning the aerial:
n
 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.
Check that the receiver is functioning properly before
n
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.
W ARNING
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.
W ARNING
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.
C AUTION
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.
