Priming Mode
– M019
Each time the spa is powered up, it will enter Priming Mode. The purpose of Priming Mode
is to allow the user to run each pump and manually verify that the pumps are primed (air
is purged) and water is flowing. This typically requires observing the output of each pump
separately, and is generally not possible in normal operation. Priming Mode lasts 4
minutes, but you can exit it earlier by pressing any Temp button. The heater is not allowed
to run during Priming Mode.
NOTE: If the spa has a circulation pump, it will turn on with Jets in Priming Mode. The
circulation pump will run by itself when Priming Mode is exited.
Water Temperature is Unknown
After the pump has been running for 1 minute the water temperature will be displayed.
Possible Freezing Condition
A potential freeze condition has been detected, or the Aux Freeze Switch has closed, and
all pumps are activated. All pumps are ON for at least 4 minutes after the potential freeze
condition has ended, or when the aux freeze switch opens.
In some cases, pumps may turn on and off and the heater may operate during Freeze
Protection. This is an operational message, not an error indication.
The Water is Too Hot
– M029
The system has detected a spa water temperature of 110
F (43.3
C) or more, and spa
functions are disabled. System will auto reset when the spa water temperature is below
108
F (42.2
C). Check for extended pump operation or high ambient temperature. During
the warmer months, changing the filter cycle is recommended to prevent the spa from
overheating with the high ambient temperature.
