EWFS Uniswitch
Operating and installation instructions
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
W ARNING
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 Engi-
neers (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.
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 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).
Therefore, check that the receiver is functioning prop-
n
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.
