or any device connected to it.
Disconnect the wireless switch from the mains by switching off at
the appropriate circuit breaker or by pulling out the fuse. Furthermore, turn off the earth leakage circuit breaker to disconnect all the
poles of the mains supply.
• Use the product only in a temperate climate, never in a tropical
climate.
• Consult an expert when in doubt about operation, safety or connection of the device.
• Maintenance, modications and repairs are to be performed exclu-
sively by an expert or at a qualied shop.
• If you have questions which remain unanswered by these operating
instructions, contact our technical support service or other technical
personnel.
Preparations for installation
Please observe the chapter “Safety instructions”!
• To use, install the wireless switch in a suitable ush or wall mounted
box or other suitable housing.
• Install the wireless switch only, if the switch is disconnected from the
mains. First switch off all poles of the mains supply by switching off
at the circuit breaker or removing the fuse and then also switch off
the associated residual current device.
Secure it against unauthorised reconnection, e.g., with a danger
sign. Then check the mains connection for absence of voltage using
a suitable tester.
Installation and connection
Refer to the section “Preparations for Installation”.
The wireless switch makes an ideal complementary component for a
standard wall switch providing an additional wireless switching function.
This means you can keep your existing wall switch (e.g. for room
lighting) and use it with an additional radio transmitter of the RS2W
radio system.
That requires, that the ush mounted box provides sufcient space for
installing the wireless switch behind the existing wall switch.
Ensure proper protection against accidental contact when
you connect, mount and later use the wireless switch.
Otherwise, there is a risk of a life-threatening electric
shock!
• Remove the cover of your existing wall
switch and take the switch out of the ush
mounted box.
• Connect the two wires on the wireless
switch to the two switch contacts on your
wall switch (“S1”), see picture to the right.
• Connect the device to the two middle
screw terminals. The connection “N” is the
neutral conductor, the connection “ ” is
the connected output/phase/L.
• The outer two screw terminals are used
for connecting to the mains voltage (“N” = Neutral wire, “L” = Phase).
• Place the wireless switch in the ush-mounted box in such a way
that the control key and the LED point outward toward you.
The control button is required for assigning to a radio
transmitter of the RS2W radio system.
Ensure that there is enough free space around the control
button, so it will not be switched on by accident.
Before mounting wall switch and cover, perform rst the teach-in
procedure.
Now, switch on the mains voltage.
Function test: Switching the connected device on/
off
using the control button
Briey press the control button on the wireless switch to switch the
connected device on or off.
The LED next to the control button shows the actual status:
• LED is on: Device is switched on
• LED off: Device is switched off
Teach-In of the wireless switch to a radio transmitter
The wireless switch can be taught-in to any radio transmitter of the RS2W radio system.
Follow the operating instructions of the radio transmitter
During the teach-in process maintain a 20 - 30 cm mini-
that will be used prior to the teaching procedure.
mum distance between the wireless switch and the radio
transmitter. Failing to do this may result in a registration
failure.
• If the wireless switch is on (LED next to the control button is on,
device is activated), switch off the wireless switch rst.
Briey press the control button, the LED next to the control button
must go dark.
The wireless switch must be switched off (LED next to
the control button is off), or else the registration process
cannot be conducted.
• Start with the registration process on the radio transmitter.
Example: On a 12-channel hand-held radio transmitter of the RS2W
radio system press the keys “ON” and “OFF” of the desired switch
channel, such as Channel 1, simultaneously until the red LED of
the hand-held radio transmitter starts ashing. Release both keys,
the red LED keeps ashing and the registration mode is enabled.
• Hold the control button on the wireless switch down for as long as it
takes the registration process to nish.
Example: On a 12-channel hand-held radio transmitter of the RS2W
radio system the LED lights up blue and then goes dark. Release
the control button on the wireless switch.
• The wireless switch switches on, and indicates that the registration
process is complete.
Up to 5 receivers can be taught-in on a switch channel of
a radio transmitter of the RS2W radio system. This means
that with one push on a button you can switch on or off up
to 5 wireless switches simultaneously for example.
It is also possible to register the wireless switch on sever-
al radio transmitter.
However, do not register a wireless switch on one single
switch channel together with a dimmer, which is available
for the RS2W wireless system! Always assign the dimmer
to a separate channel on the radio transmitter.
Deleting a taught-in wireless switch from a radio
transmitter
The procedure corresponds exactly to the teach-in procedure for the
wireless switch to the radio transmitter. For more information consult
the operating instructions for the radio transmitter of the RS2W radio
system that will be used.
Switching the device on/off
The wireless switch and the connected device can be turned off wirelessly only when it has been registered on a radio transmitter of the
RS2W radio system. Follow the description above and the operating
instructions of the radio transmitter that will be used.
The device can be switched on or off via the wireless switch which is
connected to the wall switch.
Range
The range of the radio signals between the RS2W radio system radio
transmitter and the wireless switch is up to 150 m under optimum
conditions.
This value, however, is the so-called “open space range”
(the range when transmitter and receiver are visible to
each other, without interfering inuences).
In practice, however, there may be walls, room ceilings,
etc. between the transmitter and the receiver which reduce the range accordingly.
Due to the different inuences on the radio transmission,
no specic range can be guaranteed. However, trou-
ble-free operation is usually possible in a single family
house.
Sometimes the range can be considerably reduced due to:
• Walls, reinforced concrete ceilings, light-weight walls with metal
post and beam construction
• Coated/metallised insulated glass
• Proximity to metallic & conductive objects (e.g., heating elements)
• Proximity to human bodies
• Other devices on the same frequency (e.g., wireless headphones,
wireless loudspeakers)
• Proximity to electric motors/appliances, transformers, power-supply
units, computers
Care and cleaning
The product does not require any maintenance. You should not open/
dissemble it. Repair or maintenance work must be carried out by a
specialist.
