Advanced features
11. 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.

10. Force turning on
The controller will restore to the last on/off status
on each power on as default. To force turning on the
controller at OFF status, user can connect and
disconnect the power of the controller for 3 times in a
short time. After this operation, the controller will be
reset to ON status.

8. Timing play function (-T model only)
A real time clock with backup power supply is
equipped with the -T version model. With this feature,
user can setup timing play function with multiple
repeating features of weekday or date from the Umi
Smart app.
The real time clock will set the time with smart
phone once connected to the 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.
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.
Umi protocol based on SIG BLE mesh
Yes, with backup battery. -T version
498Hz - 6.3KHz adjustable

7. Change model function
For -A and -T version controller, the function can be
changed from 1 channel (single color) to 5 channels
(RGB+CCT) by 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.
9. Change PWM frequency to avoid noise and flicker
In some LED application, noise or flicker issue may
occur at the default or low PWM frequency. The
controller’s PWM frequency can be changed via the Umi
Smart app. 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.
To change the PWM frequency, please use the Umi
Smart app and detect factory default devices in ‘Discover
nearby’ function and then tap the item icon and select
‘change setting’ menu to proceed.
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.
5. Pairing remote controllers
Operation
The controller can be paired with compatible Umi
remote controller for remote 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 remote controller's user's manual for detailed
operation.
6. Control by smartphone
For -A and -T version controller, besides Umi wireless
remote controllers, user can also control it by smartphone
with ‘Umi Smart’ app. Please scan the QR code on the
controller to find the app.
User can operate the controller from remote and/or
Umi Smart app. The working status and group/scene
setting will be synchronized.
