LANBON versionPower on. On your schedule.
A glass touch panel for a compatible storage water heater. Double-pole 16 A power switching, app control and scheduling, with EU/US formats in white or black.
L8X-HB-W · 86 × 86 mm · White · Double-pole 16 A
Your schedule
Use the app to plan power on/off around your routine.
Glass touch panel
Key backlighting indicates off, 30-minute, 60-minute and always-on states. No LCD.
Three network versions
LANBON, Tuya Wi-Fi or Tuya zigbee with the shared selector.
BEFORE INSTALLATION
Match the heater, circuit and protection.
Have a qualified electrician confirm the actual heater load, installation and protective devices. This product switches power; the heater retains its own thermostat and safety functions.
Power and neutral
AC 100–250V · 50/60Hz · Neutral required
Current and load
Double-pole 16 A. Compatible single-phase resistive storage water heater, within 16 A at the actual supply voltage.
Control boundary
Power on/off only; no water-temperature sensing, setting or adjustment.
Required protection
Keep the required upstream circuit/leakage protection and heater safety devices. No independent leakage, overload, overcurrent, short-circuit, overheat or dry-heating protection.
Wall box and conductors
Greater than 38 mm usable depth plus wiring space; 14–12 AWG for the double-pole version.
Network
Follow setup requirements for the selected networking version.
KEY BACKLIGHT · TIMER STATUS
One key. Four power and timer states.
Press the centre key to cycle through 30 minutes, 60 minutes, always on and off. The key backlight indicates the selected timer state.

CURRENT STATE
Steady green
Heater power is off. The green key backlight stays on.
| Press | Power / timer state | Key backlight | At timer end |
|---|---|---|---|
| Off / initial | Off | Steady green | No timer |
| First press | 30-minute timer | Slow blue flash: 1 s on / 1 s off | 30 min: off, steady green |
| Second press | 60-minute timer | Fast purple flash: 0.5 s on / 0.5 s off | 60 min: off, steady green |
| Third press | Always on | Steady red | No timer |
| Press again | Off | Steady green | No timer |
The original product photo supplies the exact key outline and shower icon. When the backlight flashes off, the gray key marking stays visible. Interactive illustration, not a connected heater. “Preview timer expiry” skips the illustration countdown; actual timers are 30 or 60 minutes. Power on does not indicate temperature or hot-water readiness. Reduced-motion settings show steady colours with the flash pattern described in text.
EVERYDAY POWER CONTROL
Plan power. Let the heater manage heating.
At the wall
Cycle the centre key through 30 minutes, 60 minutes, always on and off.
From your phone
Use the app for your selected networking version. Remote access requires internet and available services.
Schedules and timers
Set power on/off times in the app. Timer durations are not heating-time or water-temperature guarantees.
Keep the right safeguards
The switch does not replace the heater thermostat, dry-heating protection or upstream electrical protection. Confirm all of them as part of the installation.
LANBON APP
Keep power control close.
The supplied LANBON screens show heater power control, timer shortcuts and schedules. Screens are examples, not a live connection. This model does not support energy monitoring or temperature control.
LANBON · L8X · WI-FI MESH
Switches form their own network.
Compatible L8X series switches share a network without a dedicated gateway. Configure the first switch near the router as the master, then configure the remaining switches.
Control through LANBON Smart Living. Remote features still require a router, internet and available services. Switch Mesh does not extend Wi-Fi for phones or computers.
YOUR PANEL CONFIGURATION
The same power switch, from every angle.

The front drawing is an enclosure example, not the selected heater-key layout. Its 32 mm dimension does not establish sufficient usable wall-box depth. Confirm the installed model, circuit and current firmware power-restoration behavior.
QUALIFIED INSTALLATION
Confirm the complete heater circuit.
- Isolate the supply. A qualified electrician confirms the actual double-pole 16 A model, neutral and earthing requirements.
- Check the storage heater is a compatible single-phase resistive load within 16 A at the actual supply voltage. Do not use for instantaneous, gas or inductive loads.
- Use current exact-model wiring instructions. Confirm conductor size, terminal torque, protective devices and sufficient wall-box space.
- Secure the panel before restoring power. Verify on/off and schedules while retaining the heater thermostat and safety systems.
