Caution: This controller applies to high
voltage LED strip. Please carefully ensure all wire connections and
polarities are correct and secure before applying power, otherwise,
this controller or high voltage LED strip will be damaged.
Wiring Diagram – S3(WT) for RGB

Note: Please refer to the actual test distance
before installation. Make sure the WiFi router is in the 2.4G band
and not in the 5G band. Keep the distance between S3(WT) devices
and the router close and check the WiFi signals.
Controller Setup:
- Press and hold the match/set key on the controller for 12
seconds until the RUN LED indicator turns red. - Release the match/set key.
- The controller will become RGB type.
- Use the Tuya APP for smart configuration or short press the
match key to match with RGB RF remote.

Note: 1. Press and hold Match/Set key for 2s, switch 3 kinds light type in sequence. 2. For CCT light type, continuous power on and off will change 3 levels color temperature (WW, NW and CW) in sequence. 3. Switch off the power, then switch on power, repeat again. Immediately short press match key 3 times, the light on/off time will change between 3s and 0.5s.
AC Push Dim Function (Optional)
Short press: Turn on or off light. Long press (1-6s): Press and hold to step-less dimming, With every other long press, the light level goes to the opposite direction. Dimming memory: Light returns to the previous dimming level when switched off and on again, even at power failure.
