Initial Start-up
When your spa is first actuated, it will go into Priming mode
(after displaying some configuration information). Please
see “Spa Behavior -- Start-up Information” for additional
information.
The Priming mode will last for up to 4 minutes and then the
spa will begin to heat and maintain the water temperature
in the Standard mode. You can exit Priming mode early by
pressing “Warm” or “Cool.”
Mode/Prog
This button is used to switch between standard, economy,
and sleep modes. Press “Mode/Prog” to enter mode
programming, press “Cool” to cycle through to desired mode
(LCD flashes until confirmed), then press “Mode/Prog” to
confirm selection
Standard mode maintains the desired temperature. Note
that the last measured spa temperature displayed is current
only when the pump has been running for at least 1 minute.
The “ ” icon will display until the mode is changed.
Economy mode heats the spa to set temperature only during
filter cycles. The “ ” icon will display until mode is
changed. Pressing “Jets 1” while in Economy mode puts the
spa in Standard-In-Economy mode, which operates the
same as Standard Mode, then reverts to Economy Mode
automatically after 1 hour. Both the “ ” and
“ ” icons display in this mode. During this time,
a press of the “Mode/Prog” button will revert to Economy
Mode immediately.
Sleep mode heats the spa to within 20°F (11°C) of the set
temperature only during filter cycles. The “ ” icon
will display until mode is changed.
Standby Mode
Pressing “Warm” or “Cool” then “Jets 2” will turn off all
spa functions temporarily. This is helpful when changing
a filter. Pressing any button resets the spa. On some
systems the “Jets 1” button will control the pump in
Standby Mode (“Drain Mode”). In this case, press any
other button to exit.
