3-Product description
Lighting on/off touch panel provides on /off switch control for loads
up to 1000W. It is designed to operate with or without a neutral wire.
The panel is compatible with Somfy Gateway and the TaHoma App,
but can also be used as a standalone product. The panel can be used
as a relay switch or a remote control, which can be linked to another
relay channel to control the same light source.
Before installation, read the following tips carefully:
1. Avoid using a metallic wall box as it will block the radio signals
and shorten the wireless range.
2. For optimal results, use a wall box with a depth of 50mm.
3. The wireless range may be affected by certain materials or
objects, such as mirrors, metal, or high power electronic devices.

the power cut.
6- Technical Specification
7 - Troubleshooting
#Connect a single live power stabilizer (9026652) across the light load
to prevent it from flickering when a single-live wire connection is used.
Step 3 - Install the lighting on/off touch panel on the wall
Step 4 - Ensure there is no short circuit or incorrect wiring.
Turn on the Miniature Circuit Breaker (MCB).
Touch Link #During linking process. The two panels should be placed
close to one another (within 30cm).
• Press and hold button B (remote control) for 7 seconds, and then
release it when you hear two short beep sounds. The panel will enter
linking mode as a remote control and the back light blue LED will

flashing blue LED will return to normal.
• Press and hold button C (load switch). You will hear two short beep
sounds at 7 seconds. Keep holding the button until you hear a long
beep sound after 12 seconds, then release the button. The panel will

Step 5 - Reset and pair with gateway:
• Remove the glass panel, then press and hold the PROG button for 10
seconds until the red LED starts flashing. The LED will flash 3 times
in red and you will hear a beep sound indicating the panel has been
reset to the factory defaults. The panel will then enter pairing mode
immediately. The flashing blue LED will turn to constant blue when
the panel has joined a zigbee network.
• Use the app to configure the zigbee network of your gateway:
- On the home page, select , and then select Configuration.
- Click on Add Device. The app will prompt you to select the device type.
- Choose zigbee, and then follow the instructions in the mobile app to
complete the configuration.
Unpair from gateway/reset to factory defaults: Remove the glass
panel, then press and hold the PROG button for 10 seconds until the red
LED starts flashing. The LED will flash 3 times in red and you will hear
a beep sound indicating the panel has been reset to the factory defaults.
The panel will then enter paring mode and search for zigbee network
for 3 minutes. If it unable to join a zigbee network within 3 minutes, the
flashing blue LED will turn off, and the red LED will flash 5 times. The
panel will then be unpaired.
Step 6 - Reinstall the glass panel and wait 20 seconds for the touch
calibration to complete, before operating the switch.
Step 7 -Configure multiple control points.
If you use Somfy gateway
and app in your system, pair the
panels first with your gateway,
then use touch link to configure
multiple control points
(e.g. use button B to wirelessly
control the light bulb
connected to switch C).
