DOUBLE-POLE SWITCHING
One switch opens both lines.
A typical single-pole switch opens the live conductor and leaves neutral connected. L7-HB switches both conductors together. This matters when a project specifies disconnection of both supply conductors at the load.

Switching principle shown. Install separate residual-current and overload protection as required. For servicing, have a qualified electrician isolate the circuit and verify absence of voltage.
LANBON APP
Control power and set a schedule.
The supplied app screens show the heater power state and timer. Remote access requires the matching host switch and internet service.
LANBON L7 · WI-FI + ZIGBEE
A switch at the heart of your L7 network.
The LANBON version must be used with a LANBON L7 host switch. The host connects to your router through Wi-Fi; the other L7 switches connect to the host through Zigbee.
