Operation and programming
A s it is necessary to avoid all contact with the current sen-
sor when the device is installed, (the Phase-L line which
feeds through the sensor is only lightly insulated), we rec-
ommend that you carry out programming before installing
the radio transmitter.
a) Resetting the radio transmitter
At initial start-up, you should rst perform a reset and only
then programme the radio receiver(s).
A reset also deletes all programmed/saved radio recei-
vers tuned (e.g., when you want to reset the radio-trans-
mitter to the factory settings).
Proceed as follows to perform a reset:
• Briey press the control key (3) so that the LED (4) lights up.
• Hold the control key down until the LED (4) ashes. Release the
control key. The programming mode is now activated.
• Hold down the control key again until the LED ashes fast, then
goes off, and then ashes fast again then goes off. Then release
the control key.
• All programs are now erased.
b) Programming a radio receiver to the radio-transmitter
It is possible to program up to 5 different radio receivers
(e.g., radio-controlled switch) for each radio transmitter
of the RS2W radio system. However, do not mix radio-
controlled switches and dimmers.
• Switch off the radio receiver of the RS2W radio system that you want
to program using its control key (see operating instructions for the
radio receiver used).
• Briey press the control key (3) on the transmitter so that the LED
(4) lights up.
• Press and hold the programming key (3) until the LED ashes. Re-
lease the control key.
• Hold down the control key on the radio receiver until the program-
ming process on the radio transmitter is complete.
• The radio receiver switches on to indicate the end of the program-
ming process.
c) Deleting a radio receiver from the radio-transmitter
Please proceed as described in the programming process.
d) Deleting a defective/ lost radio receiver, and then program-
ming a new radio receiver
Defunct or lost radio receivers can of course, no longer be deleted
from the radio transmitter (see above under Section c).
Procedure 1:
Perform a reset of the radio transmitter (see above under a). Here,
however, all programmed radio receivers are deleted from the radio
transmitter and must be programmed again.
Procedure 2:
When the radio transmitter has no response to a key command from
a radio receiver at least 20x, the internally occupied memory is re-
leased.
The memory is not deleted, but only released for over-
writing with a new program (see section b). As long as no
new radio receiver is programmed, the data is retained!
Radio transmitter function
The radio transmitter has a sensor that must be attached to a power
line (phase / L). This senses whether there is an electrical current run-
ning through. In response, the corresponding receiver for the RS2W
radio system is activated.
• Current available (approx. > 0.1 A): Radio transmitter sends switch-
on command
• No power or only low current available (approx. <0.1 A): Radio
transmitter sends switch-off command
In the vicinity of 0.1 A, the switching state is undened.
Here, it is not only the component tolerances in the radio
transmitter that matter, but also the position of the cable
(phase / L) of the power line in the opening of the sensor.
The radio transmitter may be set into e.g., a ush-mounted box behind
a socket (if the ush-mounted box is deep enough). If a consumer is
now connected to the socket and the current consumption is greater
than approx. 0.1 A (power consumption greater than approx. 25 W),
the radio transmitter sends a switch-on command to the programmed
receivers of the RS2W radio system.
If the consumer is switched off or unplugged, the radio transmitter
sends a switch-off command to the programmed receiver of the RS2W
radio system.
Installation
Please observe the chapter “Safety instructions”!
First switch off at all poles the mains voltage for the power
line to be used (whose phase / L is to be routed through
the opening of the current sensor). To do this, switch off
the associated fuse and FI circuit breaker.
Verify the absence of voltage by using an appropriate
measuring instrument.
• First insert a battery correctly into the radio transmitter and program
the radio transmitter so that the desired radio receivers are regis-
tered (see chapter “Operation and programming”).
• The phase / L of a power line to be used for switching must be rout-
ed through the opening (2) of the current sensor (1). The wire must
be insulated and the insulation must not be damaged or broken.
Feed only the Phase/L through the current sensor; not the N-Neutral
nor the protective Earth wire (PE).
• Place the radio transmitter in an appropriate position. If necessary,
x it in place with some double-sided tape.
• Make sure it is properly protected.
• Switch the voltage supply back on.
Range
The transmission range of the radio signals, between the radio trans-
mitter and the radio receivers in use is up to 150 m under optimal
conditions.
This value, however, is the so-called “open space range”
(the range when the transmitter and receiver are in line of
sight, without any interference).
In practice, however, there may be walls, room ceilings, etc. between
the transmitter and the receiver, which will reduce the range accord-
ingly.
Due to the various inuences on wireless transmission, no specic
range can be guaranteed. However, trouble-free operation is usually
possible in a single-family home.
Sometimes the range can be considerably reduced due to:
• Walls, reinforced concrete ceilings, metal-framed drywalls
• 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 speakers)
• Proximity to electric motors/appliances, transformers, power sup-
plies, computers
Care and cleaning
Apart from the occasional battery change, the product is mainte-
nance-free. Due to the installation position (contact protection is re-
quired) cleaning is not possible / necessary.
