Advanced features
10. Protection feature
The controller has full protection function against
wrong wiring, load short circuit, overload and overheat.
The controller will stop working and the indicator will
flash with red / yellow color to indicate the malfunction.
The controller will try to recover from protection status
in a short time when the working condition is good.
For protection issues, please check the situation
with different indicator information:
Red flash: Check the output cables and load, make
sure no short circuit and the load current is in rated
range. Also the load must be constant voltage type.
Yellow flash: Check the installation environment,
make sure in a rated temperature range and with good
ventilation or heat dissipation condition.

7. Change model function
The working mode can be changed from 1 channel
(single color) to 5 channels (RGB+CCT) from the Umi
Smart app.
To change the model function, please use the Umi
Smart app and detect factory default devices in ‘Discover
nearby’ function and then tap the item icon and select
‘change function’ menu to proceed.
Operation
6. Pairing Umi remote controllers
The controller can be paired with compatible Umi
remote controller for direct setup and operation. To pair
or unpair the remote controller, user needs to connect
and disconnect the power of controller and press
specific combo keys on the remote controller. Each
controller can be paired up to 5 remote controllers,
please refer to the Umi remote controller's user's
manual for detailed operation.
5. Control by smart phone
The controller can be controlled by both ‘Umi Smart’
and ‘Tuya Smart’ smartphone app synchronously.
For Tuya setup, please make sure the controller is at
factory default mode and not connected to any gateway or
router. For Umi Smart app, please scan the QR code on
the housing to download.
8. Timing play function (-T model only)
A real time clock with backup power supply is
equipped with the -T version model. User can use Umi
Smart app to setup timing play function with multiple
repeating features of weekday or date.
The real time clock will set the time with smart
phone once connected to the Umi Smart app. The built-
in backup power will reserve the timing play setting up
to 48 hours after power cut. The saved timing play
function will be invalid after the backup power runs out
and it will automatically recover once being connected
to smart phone again. For more timing play features,
please check the Umi Smart app.
9. Change PWM frequency to avoid noise and flicker
The controller’s PWM frequency can be changed via
the Umi Smart app. Please use the Umi Smart app and
detect factory default devices in ‘Discover nearby’
function and then tap the item icon and select ‘change
settings’ menu to proceed.
The frequency must be tuned with LED type and
installation. To maintain more stable working and less
power loss, please do not set to high frequency if no
noise or flicker issues occurred.
CAUTION: The controller’s efficiency will drop versus
increased frequency and the output current needs to be
derated maximum 50% with frequency higher than
4KHz. Otherwise the controller may run into overheat
protection from excess heat.
Single color, CCT, RGB, RGBW and RGB+CCT
Rated output current
(at 1KHz PWM freq.)
Max 8A for each channel, total max 24A
* output current need to be derated up to 50% when PWM
frequency is higher than 4Khz.
