To Turn light on to preset level, tap top of rocker, the dimmer fades up at the 1.5 second rate.
A second tap of the rocker fades the dimmer to full brightness.
To adjust the light level, press and hold top or bottom of rocker until desired light level is reached, and then release.
To turn lights off, tap the bottom of the rocker. The dimmer fades at the 3 second fade rate.
To quickly return to the preset level when light is on, quickly tap OFF and then ON. The lights adjust to the preset level.
To bypass the fade rate and turn the lights to full ON or OFF, double tap the dimmer for ON or OFF.
If the Master is in the OFF scene, the Master ON button illuminates when any dimmer is turned on.
To change the preset level of the current scene:
Figure 7
• Press and hold the rocker until lights reach the desired level then release.
• Press the small set button next to the switch to save the preset in memory.

MULTISET PRO® UNIVERSAL ELECTRONIC SWITCH (NON-DIM)
The MultiSet Pro® Universal Electronic Switch can be programmed as a four or five-scene non-
dim switch. When programmed as a five-scene device, it is not suitable for 3-way applications.
The default mode of the switch is as a normal (4-scene) non-dim device. The AV (5-scene) mode allows the non-dim switch to remain
off when the master ON button is pressed.
To change the mode of the switch:
1. Tap OFF on the Master to place the switch in the OFF scene.
2. Press and hold the SET button. After 3 Seconds, a green LED illuminates on the bargraph. If the switch is currently in normal
mode, the bottom green LED illuminates. If it is in AV mode, the top LED illuminates.
3. Tap the top of the rocker once to toggle the mode.
4. Release the SET button.
Note: In normal mode, a “soft start” feature is utilized to extend bulb life. In AV mode, the “soft start” feature is not
implemented.

Global Fade Rate = One fade rate for all scenes.
Each dimmer’s fade rate affects all scenes. Examples: Dimmer #1 fade rate set 7.5 sec.,
dimmer #2 set to 15 sec., and dimmer #3 set to 3 sec. When any scene is selected dim-
mers #1, 2, and 3, will respond with 7.5, 15, and 3 seconds, respectively for ON, OFF,

pair of green LEDs indicates the current “global” fade rate. The bottom LED indi-
cates the 1.5 second fade rate, the next LED up is 3 seconds, while the top LED is
2 minutes. If the bottom two LEDs are on, it indicates the 5 minutes fade rate, if
the next two LEDs up are lit, it indicates 15 minutes, while the top two LEDs
indicate the 60 minute fade rate.
Step 1
Press and hold Set
button for 3 seconds.
Step 2
Tap top of dimmer paddle

To change the fade rate that will affect only an individual scene:
1. Tap a scene button on the Master to go to a scene.
2. Press and hold the SET button.
3. After 3 seconds, either a single green LED or a pair of green LEDs indicates the
scene’s fade rate.
4. While holding the SET button, tap the top rocker until the desired fade rate is
reached.
5. Release the SET button.
6. Repeat above for each scene.
