READY-IN-REST MODE
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.

PREPARATION AND FILLING
Fill the spa 5-6” below the lip of the spa. 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
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 automatically, but the pump(s) can be energized by selecting the “Jet” buttons. 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.
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
You can manually exit Priming Mode by navigating to the “Back” button on the Priming Mode Screen. If you do not manually exit the priming mode, it
will terminate after 4-5 minutes. Once the system has exited Priming Mode, the top-side panel will display the Main Screen, but the display will not
show the temperature yet because the system requires approximately 1 minute of water flowing through the heater to determine the water
temperature.

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. The pump 1 low-speed will time out after 30 minutes. The high-speed will time-out after 15 minutes. On
non-circ systems, the low-speed of pump 1 runs when the blower or any other pump is on. If the spa is in Ready Mode, Pump 1 low 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. When the low-speed
turns on automatically, it cannot be deactivated from the panel, however the high speed may be started.
CIRCULATION PUMP MODES
The circ pump operates continuously (24 hours) with the exception of turning off for 30 minutes at a time when the water temperature reaches 3°F
(1.5°C) above the set temperature (most likely to happen in very hot climates).
FILTRATION AND OZONE
On non-circ systems, Pump 1 low and the ozone generator will run during filtration. On circ systems, the ozone will generally run with the circ pump,
but can be limited to filtration cycles. The system is factory-programmed with one filter cycle that will run in the evening (assuming the time-of-day is
properly
set) when energy rates are often lower. The filter time and duration are programmable.
A second filter cycle can be enabled as needed. At the start of each filter cycle, the water devices like blower and other pumps will run briefly to purge
the plumbing to maintain good water quality.
FREEZE PROTECTION
If the temperature sensors within the heater detect a low enough temperature, then the water devices automatically activate to provide freeze
protection. The water devices will run either continuously or periodically depending on conditions. In colder climates, an optional additional freeze
sensor may be added to protect against freeze conditions that may not be sensed by the standard sensors. Auxiliary freeze sensor protection acts
similarly except with the temperature thresholds determined by the switch. See your dealer for details.
