(emulates the Pentair SAm color changing light).
2 Party Mode: Rapid color changing building energy and excitement.
3 Romance Mode: Slow color transitions creating a mesmerizing and
calming effect.
4 Caribbean Mode: Transitions between a variety of blues and greens.
5 American Mode: Patriotic red, white and blue transition.
6 California Sunset Mode: Dramatic transitions of orange, red and
magenta tones.
7 Royal Mode: Richer, deeper color tones.
8 Blue: Fixed color.
9 Green: Fixed color.
10 Red: Fixed color.
11 White: Fixed color.
12 Magenta: Fixed color.
13 Hold: Save the current color effect during a color light show.
14 Recall: Activate the last saved color effect.
MicroBrite Color Lights can be controlled using a standard wall-mount light switch (or by
the Pentair Controller (sold separately), contact your dealer for more information. Multiple
MicroBrite color lights can be connected via a junction box and a 12 VAC transformer to a
single switch so that all lights can be switched on and off together. MicroBrite color lights
are controlled by cycling AC power to the 12 VAC transformer from a standard wall switch.
By turning the switch on and off a specific number of times, the light activates one of the
seven light show modes, fixed colors, or enables the “Hold” and “Recall” feature.
Powering on the MicroBrite Color Lights
When the MicroBrite color light is powered on, the previously selected color is displayed,
unless the HOLD or RECALL feature was previously enabled.

warning may result in serious injury or death to pool and spa users.
Selecting a MicroBrite White Light Brightness Level using a Wall Switch
MicroBrite White lights allow you to choose from one of three brightness levels (100%,
75% and 50%). Whenever the MicroBrite white light is turned on, it starts at its highest
brightness level (100%). Unless it was previously set to the medium (75%) or low
brightness level (50%).
NOTE: MicroBrite Color models are not equipped with dimming functionality. Only
MicroBrite White lights have dimming functionality.
To select one of the three brightness levels (100%, 75% and 50%) first power on the
lights, then by rapidly cycling the light switch OFF and ON a specified number of times,
you can select the desired light brightness level.
Selecting the light’s brightness levels is as follows:
• 100% Brightness: Switching the lights OFF then rapidly back ON, will set
the lights to 100% brightness.
• 75% Brightness: Switch OFF-ON-OFF-ON and the lights will come on at
100% them dim to 75% after 1 second.
• 50% Brightness: Switch OFF-ON-OFF-ON-OFF-ON and the lights will
come on at 100%, dim to 75% after one second and then dim to 50% after
another second.
MicroBrite White Light
MicroBrite White Lights can be controlled using a standard wall-mount light switch.
Multiple MicroBrite white lights can be connected via a junction box and a 12 VAC trans-
former to a single switch so that all lights can be switched on and off together. MicroBrite
White lights are controlled by cycling AC power to the 12 VAC transformer from a stan-
dard wall switch. By turning the switch on and off a specific number of times, you can
choose from one of three brightness levels.
