Temp Control (80°F - 104°F / 26°C - 40°C)
The last measured water temperature is constantly displayed.
The water temperature displayed is current only when the
pump has been running for at least 2 minutes.
On panels with a single “Temp” or “Set” button, to display
the set temperature, press the button once. To change the set
temperature, press the button a second time before the display
stops flashing. Each press of the button will continue to either raise
or lower the set temperature. If the opposite direction is desired,
allow the display to revert to the current water temperature. Press
the button to display the set temperature, and again to make the
temperature change in the desired direction.
On panels with “Warm” and “Cool” buttons, to display the
set temperature, press “Warm” or “Cool” once. To change the set
temperature, press a temperature button again before the display
stops flashing. Each press of “Warm” or “Cool” will adjust the
set temperature.
After three seconds, the display will stop flashing and begin to
display the current spa temperature.
Jets 1
Press “Jets 1” to turn pump 1 on or off, and to shift between low
and high speeds (if equipped). The low-speed will turn off after
4 hours. High-speed will turn off after 15 minutes. Low-speed
may run automatically at times, during which it cannot be
deactivated from the panel, but high-speed may be operated.
Jets 2/Jets 3/Blower (If equipped)
Press the corresponding button once to turn the device on or
off. The device will turn off after 15 minutes. Pump 2 may be
two-speed on some systems.
Some systems use this one button to control two devices. The first
button press will activate one device. Press again to have both
devices active. Press again to turn off the first device only. Press
one more time to turn both devices off.
Initial Start-up
Your spa will enter Priming Mode ( ) when it is energized.
During Priming Mode, press “Jets” button(s) repeatedly and
be sure all pumps are free of air. Priming Mode lasts less than
5 minutes. Press “Temp” to exit. After Priming Mode, the spa
will run in Standard Mode (see Mode section). Some panels may
not have a “Temp” button. On these panels the “Set,” “Warm,” or
“Cool” buttons are used.
Button shapes and labels may vary.

momentarily when you switch into Standard Mode.
Economy Mode heats the spa to the set temperature only during
filter cycles. will display when water temp is not current, and
will alternate with water temp when the pump is running.
Sleep Mode heats the spa to within 20°F/10°C of the set
temperature only during filter cycles. will display when water
temp is not current, and will alternate with water temp when the
pump is running.
Preset Filter Cycles
The first preset filter cycle begins 6 minutes after the spa is
energized. The second preset filter cycle begins 12 hours later.
Filter duration is programmable for 2, 4, 6, or 8 hours or for
continuous filtration (indicated by ). The default filter time is
2 hours for non-circ systems and 4 hours for circ systems.
To program, press “Temp,” then “Jets 1.” Press “Temp” to adjust.
Press “Jets 1” to exit programming.
For non-circ systems, low-speed pump 1 and the ozone generator
(if installed) run during filtration.
For circulation systems, the circ pump and the ozone generator
(if installed) run 24 hours. In hot environments, the circ pump
may turn off for 30 minute periods, except during filter cycles.
At the beginning of each filter cycle all other equipment will run
briefly to purge the plumbing.
The pump responsible for heating and filtration (pump 1 low-speed
on non-circ system, or the circ pump on circ systems) will be
referred to simply as the pump.
In multi-button sequences, if the buttons are pressed too quickly in
sequence, they may not register.
