off after a timeout period.

Press the “Jets 3” button once to turn pump 3 on or 
off, and to shift between low and high speeds if it is a 
two-speed pump. If left running, the pump will turn off 
after a timeout period. “Jets 4” operates the same way 
as “Jets 3”.

Jets 5, Jets 6

(optional on some systems)

Press the “Jets 5” button once to turn pump 5 on or off. 
If left running, the pump will turn off after a timeout 
period. “Jets 6” operates the same way as “Jets 5”.

Mister 

(optional)

Press the “Mister” button to turn the Mister on and off. 
If left on, the mister will automatically turn off after 
15 minutes.

Option 

(optional)

Press the “Option” button to turn optional equipment 
(such as TV or Stereo) on and off (with no timeout).

TV Lift 

(optional)

Press the “TV Lift” button to raise and lower the TV Lift 
device. There is no timeout for this feature.

Blower 

1-speed operation: on/off;
2-speed operation: med/hi/off; or
3-speed operation: lo/med/hi/off.
If left on, the blower will automatically turn off after a 
timeout period.

Fiber 

(optional on some systems)

If a fiber-optic light with wheel is installed, press the 
“Fiber” button once to start the light and wheel, press 
it again to stop the wheel, and then again to turn the 
light off. The fiber icon stands still when the fiber-optic 
light is on by itself, and rotates when the color wheel is 
also on.

Both spa light and fiber-optic light can be used 
simultaneously on systems that have both. If either light 
is left on, it will automatically turn off after a timeout 
period (on some systems this timeout can be as long as 
4 hours.)

Use the “Light” button if your fiber-optic system is on/off
only (no separate wheel stop).
