ML550 Quick Reference Guide
Initial Start-up
When your spa is first actuated, it will go into Priming mode
(after displaying some configuration information).
Please
see the M-7 Installation Instruction Manual for complete
instructions on Power-up and Pump Priming.
The Priming mode will last for up to 4 minutes and then the
spa will begin to heat and maintain the water temperature
in the Standard mode. You can exit Priming mode early by
pressing “Cool” or “Warm.”
Cool/Warm
Press the “Cool” or “Warm” button once to display the set
temperature. Each time either button is pressed again, the
set temperature will increase or decrease depending on
which button is pressed. After three seconds, the LCD will
automatically display the last measured spa temperature.
Jets 1
Press the “Jets 1” button once to turn pump 1 on or off,
and to shift between low and high speeds if equipped. If
left running, the pump will turn off after a timeout period.
The pump 1 low speed timeout 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 mode. When the
low speed turns on automatically, it cannot be deactivated
from the panel; however, the high speed may be started.
