Installation instructions

• To connect the Device, we recommend using solid single-core wires or stranded wires with ferrules. The wires should have insulation with increased heat resistance, not less than PVC T105°C (221°F).
• When connecting wires to the Device terminals, consider the specified conductor cross section and stripped length. Do not connect multiple wires into a single terminal.
• For security reasons, after you successfully connect the Device to the local Wi-Fi network, we recommend that you disable or password-protect the Device AP (Access Point).
• To perform a factory reset of the Device, press and hold the Con-trol button for 10 seconds.
• To enable the access point and the Bluetooth connection of the Device, press and hold the Control button for 5 seconds.

Connect the first load to the O1 terminal of the Device and the Neutral wire as shown in the wiring diagram.
Connect the second load to the O2 terminal of the Device and the Neutral wire as shown in the wiring diagram.
Connect the Live wire to the L terminal.

If you want to control the dimming with a single button (per channel), connect buttons to the SW1 and SW3 terminals and to the Live wire as shown in Fig. 1 b).
If you want to control the dimming with two buttons (per channel), connect buttons to the SW1, SW2, SW3, and SW4 terminals, and to the Live wire as shown in Fig. 1 a).
If you want to just turn the lights on or off, connect the switches to the SW1 and SW3 terminals and the Live wire as shown in Fig. 1 c).
