Mechanical Structures and Installations
Match Remote Control (two match ways)
End user can choose the suitable match/delete ways.
Two options are offered for selection:
Use the controller’s Match key
- Match: Short press match key, immediately press on/off key (single zone remote) or zone key (multiple zone remote) on the remote. The LED indicator fast flash a few times means match is successful.
- Delete: Press and hold match key for 5s to delete all match, The LED indicator fast flash a few times means all matched remotes were deleted.
Use Power Restart
- Match: Switch off the power, then switch on power, repeat again. Immediately short press on/off key (single zone remote) or zone key (multiple zone remote) 3 times on the remote. The light blinks 3 times means match is successful.
- Delete: Switch off the power, then switch on power, repeat again. Immediately short press on/off key (single zone remote) or zone key (multiple zone remote) 5 times on the remote. The light blinks 5 times means all matched remotes were deleted.
Light on/off fade time
- Long press match key 5s, then short press match key 3 times, the light on/off time will be set to 3s, the indicator light blink 3 times.
- Long press match key 10s, restore factory default parameter, the light on/off time also restore to 0.5s.
Wiring Diagram
for RGB/RGBW
Note: If connect with RGB LED strip, please long press match key for 15s, the controller will become RGB type.
For dual color
For single color
RGB/RGBW Dynamic mode list
| No. | Name | No. | Name |
| 1 | RGB jump | 6 | RGB fade in and out |
