the temperature display may not show a current temperature until the
heater pump has been running for a minute or two.
While Pump 1 High can be turned on and off, Pump 1 Low will run until
set temperature is reached, or 1 hour has passed.
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 pro-
grammed filter times, even though the water is being filtered constantly
when in Circulation Mode.
READY-IN-REST
READY/REST appears in the display if the spa is in Rest Mode and the
Jets 1 Button is pressed. It is assumed that the spa is being used and
will heat to set temperature. While Pump 1 High can be turned on and
off, Pump 1 Low will run until set temperature is reached, or 1 hour has
passed. After 1 hour, the System will revert to Rest Mode. This mode
can also be reset by entering the Settings Menu and changing the Heat
Mode.
FILL IT UP!
PREPARATION AND 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, 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. The system will automatically return to normal
heating and filtering at the end of the priming mode, which lasts 4-5
minutes. During the priming mode, the heater is disabled to allow the
priming process to be completed without the possibility of energizing the
heater under low-flow or no-flow conditions. Nothing comes on auto-
matically, but the pump(s) can be energized by selecting the “Jet” but-
tons. If the spa has a Circ Pump, it can be turned on and off by press-
ing the “Circ Pump” button during Priming Mode. In addition, if the spa
has a Circ Pump, it can be activated by pressing the dedicated “Light”
button during Priming Mode. Manually exit Priming Mode by pressing the
“Exit” Button.
PRIMING THE PUMPS
As soon as the Priming Mode screen 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 ener-
gize the heater and go into an overheat condition.
EXITING PRIMING MODE
You can manually exit Priming Mode by navigating to 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 tem-
perature yet, as shown below. This is because the system requires ap-
proximately 1 minute of water flowing through the heater to determine the
water temperature and display it.
