Three custom speed shortcuts
Set each preset within 1%–100%. These are control settings, not fixed measured RPM.
L9-HF · LCD SMART FAN SWITCH
LANBON versionYour breeze. Your light.
Control one compatible AC fan and an independent light from the LCD panel or the app for your selected version. Save three personal speed shortcuts, or start a selected preset as you approach.
US white · One AC motor · Neutral requiredComfort, with separate controls.
Fan and independent light
Fan speed control ≤200 W, plus light on/off ≤200 W. Lighting is not dimmable on this model.
Welcome on approach
Wake the screen, enable lighting response and start a selected fan-speed preset. Configure the desired actions in the menu.
BEFORE INSTALLATION
Start with the right AC motor.
A qualified electrician must check the actual motor, supply, loads and wiring. Never swap or combine the fan and light outputs.
Power & neutral
AC 100–250V · 50/60Hz · Live and neutral required
Fan circuit
One compatible single-phase AC / PSC motor ≤200 W. No parallel motors.
Light circuit
Independent relay on/off ≤200 W; no dimming.
Motor compatibility
No DC variable-speed fans or fans with built-in remote receivers or smart speed modules.
Starting recommendations
Motor load >15 W and starting setting >10%. Verify reliable starting with the actual motor; never test speed control without a motor.
US installation
84 × 128 mm panel, 25 mm in-box body and factory lead wires. Confirm usable box depth and approved connector space.
LCD FAN CONTROL
Fan speed and light, separately controlled.
Choose fan-only or fan-and-light operation to match the installed circuits. The three speed shortcuts are individually customisable; changing device type resets the device and requires reconfiguration.
Control one compatible AC fan without a lighting control button.
Actual device interfaces, not a live connection. Speed settings are not measured motor RPM.
PERSONALISE YOUR DISPLAY
Choose the display that feels right.
L9 · Themes
Six themes for your everyday controls.
Choose a supplied display theme; adjust working and standby brightness separately in device settings. Screen colours do not change the room light's colour or brightness.

YOUR SPEED PRESETS
Three shortcuts. Your own settings.
Explore the supplied shortcut-selection interfaces. Set each shortcut within 1%–100%; actual speed and reliable starting depend on the connected motor. TRIAC regulation may produce a slight hum with some motors at lower settings.
The images show selected shortcut buttons, not three fixed speeds or a measured RPM comparison.
A WELCOME WITHOUT A TOUCH
Walk closer. Let the breeze welcome you.
Wake the screen, switch on the light as you approach, or set a delayed light-off. Screen wake and lighting automation can be enabled and configured separately in the device menu.
Choose which fan-speed preset starts on approach in the device menu. The illustration combines screen wake, lighting and fan start. Delayed light-off does not mean delayed fan-off; fan behaviour is configured separately. Blade motion is illustrative, not measured RPM.
FUNCTION ILLUSTRATION
Room light offScreen standby illustrationFan standby illustration
Standby
Illustrates the enabled screen-wake and lighting functions together. The scene and screen shading are illustrative, not a device recording. Playback time is compressed, not a response-time test or a device delay setting. Screen standby is illustrated separately from the lamp's delayed switch-off; its timing is configured independently.
1 mNear / low
2 mMedium
Up to 4 mFar / high
Choose near, medium or far in the device menu. Check sensing and delay at the actual installation; these settings are not a guaranteed coverage area. Brightness and night settings are adjustable separately.
SMART LIVING
Keep fan control within reach.
Use the supplied Smart Living interfaces for fan control, schedules and energy information. Screenshot values illustrate the interface, not measurement accuracy. Remote features require setup, internet and available services.
WI-FI MESH
L9 series. Different controls, one Mesh.
L9 2-in-1, dimmer and fan switches can share one Mesh network. Switches connect through neighbouring nodes, so each switch does not need a direct Wi-Fi link to the router.
No dedicated gatewayA switch acts as the master

Dimmer switchConnects through Mesh≤8 m
Fan switchConnects through MeshStart near the router
Configure the first switch where the router signal is good. The system automatically sets this first configured switch as the master.
Add the other switches
Complete setup for the other compatible switches. Keep adjacent Mesh switch nodes no more than 8 metres apart.
Let switches form the network
The switches automatically form their Mesh network. Any compatible switch can serve as the master when configured first; a separate gateway or host is not required.
L9 can also mesh with compatible L10 switches; this diagram shows L9 examples only, not a required bundle. It does not extend Wi-Fi for phones or computers. Remote app and cloud features still require the router, internet access and available services.

The current body occupies 25 mm inside the box and uses factory lead wires. Device depth alone is not a minimum box requirement. Confirm usable depth, conductors and approved connectors before ordering.
Use the right load on each output.
Compatible AC fan
One compatible traditional single-phase AC ceiling, exhaust or wall fan within 200 W. Verify TRIAC suitability, reliable starting and the required speed range.
Independent lighting
Compatible LED, incandescent or CFL lighting within 200 W. The light output switches power only; it does not dim or control a motor.
Do not connect
DC fans, fans with built-in remote/smart speed modules, parallel motors or overloaded circuits. Never swap fan and light outputs. Check power-restoration and automatic-start settings before use.
Check the motor and wiring first.
- Have a qualified electrician isolate power and identify live, neutral, grounding and the separate fan/light loads.
- Verify one compatible AC motor, each load limit and reliable starting at the intended settings.
- Obtain current model-specific lead-wire instructions; check actual markings, connectors and usable US wall-box space. Do not swap the outputs.
- Inspect connections before restoring power, then test the speed presets, lighting, approach actions and chosen power-restoration setting.
