Universal Dimmer Switch
NEXA CMR-101
Featuring a unique universal single dimmer receiver that allows remote control of existing household dimmable LEDs,
dimmable energy-saving lamps (CFL/ESL), incandescent lamps and halogen lamps. Hassle free wiring and easy rotary dial
setup for adjusting the lowest brightness level.
Compatible with:
! Incandescent and halogen lamps (230V~) up to 200W
! Dimmable energy saving lamps (CFL/ESL) up to 24W
! Dimmable LEDs 230V 3- 24W
The universal dimmer receiver has a built-in 8 step rotary dial to adjust the lowest brightness according to the different
types of lamp(s) used.
To adjust to the lowest brightness, simply turn the rotary dial from 8 to 1.
Synchronising dimming level. (Different brands and wattage may vary the brightness level)
！It is recommended to use the same brand of load at the same time.
To operate, the universal dimmer receiver must first be wired up.
！Please refer to section “Wiring” below.
1. Connect all loads first and switch the rotary dial to position 1.
2. Switch the rotary dial from 1 to 8 and the loads will turn ON automatically. (No need to use transmitter).
3. Alter the rotary dial from 8~1 to adjust to the lowest brightness.
4. Each time the dial is moved to the next number, the lamp will increase to 100% brightness then dim to the relevant
brightness (can achieve the full range of dimming).
◎Take LED lamps as an example.
Adjust the rotary dial from 8 to 7 (fig.1); if the LED lights up normally then 7 to 6 can be adjusted (fig.2), until the LED
flickers or turns OFF, then adjust back to the previous number.
For example, 7 to 6 (fig. 3). In this case, the rotary dial should be setup in ‘7’ allowing both LEDs to be dimmed at the
set up level.

Wiring
Before commencing work, ALWAYS isolate the mains power supply and switch off the circuit breaker.
If the universal dimmer receiver is to be installed into a wall box, dismantle the screw tab holder.
Connect AC wire and load to receiver block terminal.
A) Live AC 230V wire into terminal “L-in”
B) Neutral AC 230V wire into terminal “N-in”
C) Load Live wire into terminal “ "out”
D) Load Neutral wire into terminal “N"out”
E) Connect back mains power supply.
F) LED indicator turns ON and is ready for pairing.
Pairing
The universal dimmer receiver can pair with up to 6 different remote controls at any one time as it has a maximum of 6
memories.
This receiver is not to be controlled by the “Code Switch System” remote transmitters (like TMT-502).
Only compatible with the “Self Learning System” remote transmitters.
Pairing using LEARNING MODE:
1. On the universal dimmer receiver press the ‘Learn’ button once, the red LED will
flash. The universal dimmer receiver is now in learning mode.
2. Using a remote control press the ‘ON’ button intended to be paired; the load will flash
twice to confirm that the remote control is now paired.
NOTE: Learning Mode lasts for 12 seconds; if no signal is received from a remote control

during this time then the dimmer switch will automatically exit learning mode without pairing the device.
！If, during learning mode the load does not flash to confirm, this means that the universal dimmer receiver memory is
FULL and no further remote control remote controls may be paired with it unless one of the existing remote controls is first
unpaired (see below).
Unpairing
Removing single Device:
1. On the universal dimmer receiver press the ‘Learn’ button once, the red LED will flash. The universal dimmer receiver
is now in learning mode.
2. Using a remote control press the ‘OFF’ button intended to be unpaired; the load will flash twice to confirm that the
remote control is now unpaired.
Clearing Memory (will remove all paired remote controls):
On the universal dimmer receiver press the ‘Learn’ button for 6 seconds (LED on receiver will flash), release then press
once again. The load will flash twice to confirm that all remote controls are now unpaired.
Operation
Soft start ON/OFF Function:
Press the ‘ON’ button on remote control, the lights will gradually illuminate.
Press the ‘OFF’ button on remote control, the light will gradually turn OFF.
Dimming Function:
1. Make sure the load (light) is switched ON.
2. On the remote control press the ON button again, the loads will start to dim.
3. To stop at the desired brightness level, press the ON button again.
※Dimming level dims in cycle, during the cycle if no signal is given within 4 cycles it will stop at 100% brightness』.
！If after setting a dim level, the lamp is switched off, the next time the lamp is switched ON, the light level will remain at
the last setting.
