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

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
