Circulation Mode
If the spa is configured for 24HR circulation, the heater
pump generally runs continuously. Since the heater pump
is always running, the spa will maintain set temperature and
heat as needed in Ready Mode, without polling.
In Rest Mode, the spa will only heat to set temperature
during programmed filter times, even though the water is
being filtered constantly when in 24HR circulation mode.
Ready-in-Rest Mode
Ready in Rest Mode appears in the display if the spa is in Rest
Mode and the Jets 1 Button is pressed. When the heater pump
has come on automatically (for ex-ample for heating) you can
switch between low speed and high speed but you cannot turn
the heater pump off. After 1 hour, the System will revert to Rest
Mode. This mode can also be reset by selecting the Heat Mode
line on the Screen shown here.
Fill it up!
Preparation & Filling
Fill the spa to its correct operating level. Be sure to open all
valves and jets in the plumbing system before filling to allow as
much air as possible to escape from the plumbing and the
control system during the filling process. After turning the power
on at the main power panel, the top-side panel will display a
splash screen or startup screen.
Priming Mode – M019*
After the initial start-up sequence, the control will enter Priming
Mode and display a Priming Mode screen. Only pump icons
appear on the priming mode screen. During the priming mode,
the heater is disabled to allow the priming process to be
complet-ed without the possibility of energizing the heater under
low-flow or no-flow conditions. Nothing comes on automatically,
but the pump(s) can be energized by selecting the “Jet” buttons.
If the spa has a Circ Pump, it can be turned on and off by
pressing the “Circ” button during Priming Mode.
Priming the Pumps
As soon as the Priming Mode screeen appears on the panel,
select the “Jets 1” button once to start Pump 1 in low-speed and
then again to switch to high-speed. Also, select the other
pumps, to turn them on. The pumps should be running in high-
speed to facilitate priming. If the pumps have not primed after 2
minutes, and water is not flowing from the jets in the spa, do not
allow the pumps to continue to run. Turn off the pumps and
repeat the process.
Note:
Turning the power off and back on again will initiate a
new pump priming session. Sometimes momentarily turning the
pump off and on will help it to prime. Do not do this more than 5
times. If the pump(s) will not prime, shut off the power to the
spa and call for service.
Important:
A pump should not be allowed to run without priming
for more than 2 minutes. Under NO circumstances should a pump
be allowed to run without priming beyond the end of the 4-5 minute
priming mode. Doing so may cause damage to the pump and
cause the system to energize the heater and go into an overheat
condition.
Exiting Priming Mode
The system will automatically enter the normal heating and filtering
at the end of the priming mode, which lasts 4-5 minutes.
You can manually exit Priming Mode by pressing the “Back”
button on the Priming Mode Screen. Note that if you do not
manually exit the priming mode as described above, the
priming mode will be automatically terminated after 4-5 minutes.
Be sure that the pump(s) have been primed by this time.

Once the system has exited Priming Mode, the top-side panel
will display the Main Screen, but the display will not show
the water temperature yet, as shown below. This is because
the system requires approximately 1 minute of water flowing
through the heater to determine the water temperature and
display it.

Spa Behavior
Pumps
On the Spa Screen, select a “Jets” button once to turn the pump
on or off, and to shift between low- and high-speeds if equipped. If
left running, the pump will turn off after a time-out period.
