Pair/delete the pairing with RF+Bluetooth remote

  1. wiring according to connection diagram.
  2. Pair LED controller with RF+Bluetooth remote: please refer to the instruction of the remote that you would like to pair with.
  3.  Delete the pairing:
    (1) Wire up the LED controller correctly, power on.
    (2) Press and hold down the “ Reset” button on the controller for over 3 seconds until the connected light flashes, which means well

Setting minimum brightness:
Adjust brightness to a desired level from zigbee hub or controller interface or a remote, then press and hold down “Min. Set ” key until connected light flashes, the minimum dimming level is set successfully, then the connected load can only be dimmable between this minimum brightness and 100% brightness.

The dimming range of this dimmer is 1%-100%, but some load types may flicker when dimmed to 1%, thus a minimum brightness shall be set higher than 1% to avoid flickering during dimming process.

Delete the minimum brightness:
Adjust the brightness to 100% from zigbee hub or controller interface or a remote, then press and hold down the “Min. Set” key on the dimmer until connected light flashes, which means minimum brightness is deleted successfully.

Controlled by a push switch:
Once connected with a push switch, click the push switch to switch ON/OFF, press and hold down it to increase/decrease light intensity.

Wiring diagram

Notes for the diagrams:

L – terminal for live lead
N – terminal for neutral lead
Out – output terminal of the dimmer (controlling connected light source)
+A1 – terminal for push switch
-A2 – terminal for grounding to the switch connected to the dimmer

This phase dimmer adopts leading edge dimming (forward phase control) or trailing edge dimming (reverse phase control), two versions are available for choosing, default factory setting is trailing edge, leading edge version available upon request. Please make sure the connected loads support the control type you choose.
Please refer to the user manual of the load or consult the supplier of the load
