1. General
The radio-controlled switching actuator GFU003 is suitable for ush-mounted installation in a
switch box or a junction box. It can switch lights or other electrical devices up to 500 W resistive
load with 230 V.
A 434 MHz radio receiver is integrated into the switching actuator GFU003. You can easily operate
the switching actuator with a radio handheld transmitter or a radio wall-mounted transmitter.
During assembly, please make sure that the stationary transmitters are more than 2 m away from
the receiving antenna.
You also have the option to connect a switch with two buttons / two switching functions in order to
allow selective turning on and off. These buttons must be potential-free. Please do not use here
230 V. This would damage the control.
Different acoustic signals are emitted by the control during programming.
1.1 Operation via push button and two-key transmitter
Operated key Reaction of the control
ON Light / electric device on
ON Relay is closed, light /electric device is on
OFF Light / electric device off
OFF Relay is open, light / electric device is off
The assignment of the transmitter buttons to the control commands is determined by the user while learning.
1.2 Disabling the learning mode
For safety reasons, the control programming is only possible within the rst 30 minutes after swit-
ching on the mains voltage. After the control blocks the learning procedure so that unauthorized
persons have no access to the programmed parameters. To modify the control setting, please
power off and then back on.
2. Learning mode / control set up
• A maximum of three different transmitters can be learned. The control can therefore be a part of
three independent groups.
• If three transmitters have already been learned and if an attempt is made to learn a 4th one, the
last transmitter actually stored is deleted and the new transmitter stored instead.
• If you try to learn a transmitter whose radio code has already been learned, then the learning
will be denied and a rapid succession of short tones is emitted. The control expects a different
radio code.
• Should no action be taken within 30 seconds, the learning mode will be deactivated! You will
hear six signal tones and the control returns to normal operation.
• You can only delete all learned remote codes together.
2.1 Learning a transmitter
The order sequence is specied: the rst input on a transmit button receives the function ON, the
second input the function OFF.
2.1.1 Learning the transmitter
1. Hold the transmitter to be learned directly to the receiving antenna and press a key about
3 seconds until an audible signal is emitted. The learning mode is activated.
2. Keep holding the transmitter to the receiving antenna and activate briey the key for the ON
command. The radio code is learned and an audible signal is emitted for acknowledgement.
3. The control returns to normal operating mode.
