HEATER REPORTS
conditions
of possible
freezing
Show up when conditions of possible water freezing are detected or the
AUX freeze switch has turned off while the circulation pumps and jets are
turned on. In some cases the circulation pumps can turn on and off and
the heater can run in the freeze protection mode. This is an informative
operational message, not a defect indicator.
M029
The water is too hot
One of the temperature sensors detected a water temperature of
109.94 °F and the hot tub functions are disabled. The system will
automatically rest once the water temperature falls under 107.96 °F.
Check whether the circulation pump has been running for too long or the
surrounding temperature is too high.
