General Messages
Priming Mode – MO19
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 pump is 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.
Water Temperature is Unknown
After the pump has been running for 1 minute, the temperature will be displayed.
Too Cold - Freeze Protection
A potential freeze condition has been detected, or the Aux Freeze Switch has closed, and the pump is activated, depending on
how your system was built. The pump is ON for at least 4 minutes after the potential freeze condition has ended, or when the aux
freeze switch opens.
In some cases, the pump may turn on and off and the heater may operate during Freeze Protection.
This is an operational message, not an error indication.
Water is too Hot (OHS) – MO29
One of the water temp sensors has detected spa water temp 110°F (43.3°C) and spa functions are disabled. System will auto
reset when the spa water temp is below 108°F (42.2°C). Check for extended pump operation or high ambient temp.
J29 Warning – MO44
J29 is typically used as a Heater Disable input. As such, it should not typically be shorted at power-up. This message
appears if J29 is shorted at power-up.
