Compatible Load Types

is further dependent on power factor result when connected to dimmer.
Triac Dimmable
LED drivers| 200W @ 220V
100W @ 110V| Maximum permitted number of drivers is 200W divided by driver nameplate power rating, and make sure the surge current is no more than 2 times 65A.
Incandescent lighting,
HV Halogen lamps| 400W @ 220V
200W @ 110V|

System wiring

Note:

1. The above distance is measured in spacious (no obstacle) environment, Please refer to the actual test distance before installation.
2. Please check if the WiFi router net in 2.4G band, the 5G band is not available, and do not hide your router network.
3. Please keep the distance between Si -NWT) devices and router close, and check the WiFi signals.

Wiring diagram

Caution: Please carefully ensure all wire connections and polarities are correct and secure before applying power, otherwise this controller will be damaged.

Note: When calculating the maximum number of load lamps or drivers, the input power or input current parameters of a single lamp or driver must be used, the output power parameters can not be used.
In addition, the maximum surge current of the dimmer is 65A, the sum of surge current of multiple dimmable LED drivers should not exceed 2 times. otherwise, the product will be overloaded and damaged.

Leading edge or trailing edge dimming setting
Select leading edge(forward-phase) dimmer or trailing edge(reverse-phase) dimmer according to dimmable LED light or driver.

Min brightness setting
Long press Min set key for 10s, the light blink 2 times, ready for min brightness set, then short press Min set key 1-6 times, to get 6 min brightness: 5%, 10%, 15%, 20%, 25% or 30%, the light will output the current min brightness immediately, Wait 8s, quit min brightness set automatically, the light will return output 100% brightness.
Light on/off fade time
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.

Tuya APP network connection and operation
Press and hold Match/Set key for 2s, or push twice Match/Set key fastly, Clear previous network connection, enter Smart config mode, the blue LED indicator flash fastly.
Press and hold Match/Set key for 5s:
Clear previous network connection, enter AP config mode, the blue LED indicator flash slowly.
If smart config failed, please try AP config.
If Tuya APP network connection succeed, the blue LED indicator will stop flash, and in Tuya APP, you can find Triac dimmer device.
Tuya APP interface operation:
Touch brightness slide to adjust brightness.

Match RF remote control

End user can choose the suitable match/delete ways. Two options are offered for selection:

Use the S1-B(WT)’S controller’s Match key
Match:
Short press match key of S1-B(WT), immediately press on/off key on the remote.
Delete:
Press and hold match key for S1-B(WT) for 5s to delete all match, The light blinks 5 times means all matched remotes were deleted.
Use Power Restart
Match:
Switch off the power of S1-B(WT), then switch on power, repeat again, Immediately short press on/off key 3 times on the remote.
The light blinks 3 times means match is successful.
Delete:
Switch off the power of S1-B(WT), then switch on power, repeat again, Immediately short press on/off key 5 times on the remote.
The light blinks 5 times means all matched remotes were deleted.

AC Push Dim Function

• 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.
