PAIRING
Pairing using LEARNING MODE:
1. Press ‘Learn’ button once (LED on module will flash), this will enter learning
mode.
2. With a remote control press the ‘ON’ button; LED on module will flash to
confirm that the remote control is now paired.

5.Non-Dimmable / Trailing & Leading Edge Setup
Initial factory pre-set is at ‘Leading Edge’ Position
NON-DIMMABLE LOAD
On-Off Function for non dimmable load.
Benefit to change from dimmable to non dimmable load without changing the
module and operates normally for On-Off function.
⚫Adjust rotary switch to position, LED on module will quick flash to
confirm and connected load will light up at full brightness.
⚫This confirms the mini wall module is properly setup under On-Off Function.
NON-DIMMABLE / TRAILING & LEADING EDEGE SETUP

9
Issue Date: 03/08/2022
TRAILING EDGE /LEADING EDGE /MINIMUM BRIGHTNESS LEVEL
Adjust the rotary switch on the top right-hand corner to select trailing or leading
edge by trimmer resistor.
Leading Edge
⚫Adjust rotary switch counterclockwise to the very end of R,L,C position,
LED on module will blink once to confirm the mini wall module is properly
setup under leading edge.
⚫Slowly turn clockwise to adjust the minimum brightness level. If load flickers
or turns OFF during operation, adjust counterclockwise one level up until
the load lights up and do not flicker. Please adjust to the most suitable dim
level that you desire.
⚫During ON/OFF operation LED on module will flash once.
Trailing Edge
⚫Adjust rotary switch clockwise to the very end of RC position, LED on
module will blink once to confirm the mini wall module is properly setup
under Trailing Edge.
⚫Slowly turn counterclockwise to adjust the minimum brightness level. If load
flickers or turns OFF during operation, adjust clockwise one level up until
the load lights up do not flicker. Please adjust to the most suitable dim level
that you desire.
⚫During ON/OFF operation LED on module will flash twice.

6.Operation
Mini module is compatible to “Self Learning” system and M series remote
control. Please refer to the relevant user guide for detailed operation.
Operation via Momentary / Push Switch:
Turn the load ON:
Press switch button once to turn ON load.
Turn the load OFF:
Press switch button once again to turn OFF load.
Dimming the load:
In each operation, first time dimming, load will dim up and stops at brightest
level. 2nd time dimming, load will dim down and stops at the lowest level.
1. Press switch button once to turn ON load.
2. Press and hold down switch button to start dimming.
3. At the desired brightness level release switch button to stop.
During dimming process when the load level reaches to the lowest or
brightest, to continue dimming press and hold down switch button again then at
the desired brightness level release switch button to stop.
Operation example using in conjunction with a remote control and Momentary
/ Push switch.
If load is switched ON from the Momentary / Push switch then switch OFF via
the remote control.
The next time turning ON the load can either be:
(i) on the remote press the ON button
OR
(ii) on Momentary / Push switch press switch button once.
