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 example 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 entering the Settings Menu and selecting the Heat Mode line.
* M0XX is a Message Code. Codes like this will be seen in the Fault Log.
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 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. If the spa has a Circ Pump, it can be turned on and off by pressing the
“Circ Pump” button during Priming Mode.
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 energize the heater and go into an overheat condition.
