Spa Functions
In the “Spa” menu (accessed from the Home display
screen), you can control the devices on your system. The
menu also shows the status of devices you have installed
on your system.
Home > Spa > > Spa Functions menu.
The Spa Functions menu displays only the equipment
that is installed on your system; equipment may include:
Jet Control, Lighting, Blower, etc. Highlight the selected
device, then press Select (
). Use the direction keys
to move within each menu and press Select to turn the
device On or Off, or to advance through the available
speeds (High/Med/Low).
If you do not have a device installed, the menu will
not include it.
Time Out Notes
The pump responsible for heating and filtration
(pump 1 low on non-circ systems, or the circ pump on circ
systems) will be referred to simply as the pump.
Time-outs refer to a preset length of time that a
function is programmed to operate before shutting off
automatically. Certain conditions (filters or freeze) can
cause a function to operate longer, while faults can
cause a function to operate for a shorter length of time.
The system keeps track of time-outs regardless of other
conditions occurring.
Pumps
You can turn a pump on or off, and shift between high
and low speeds if equipped. If left running, pump 1 will
turn off after a time-out period. The pump 1 low speed
time-out on some systems may be as long as 4 hours.
On non-circ systems, the low speed of pump 1 runs
when the blower or any other pump is on. It may also
activate for at least 1 minute every 30 minutes to detect
the spa temperature (polling) and then to heat to the
set temperature if needed, depending upon the mode.
When the low speed turns on automatically, it cannot be
deactivated from the panel; however, the high speed may
be started.
