General Messages
Most messages and alerts will appear at the bottom of the normally used screens. Several alerts and
messages may be displayed in a sequence.
WATER TEMPERATURE IS UNKNOWN
After the pump has been running for 1 minute, the temperature will be displayed.
THE WATER IS TOO HOT – M029*
The system has detected a spa water temp of 110°F (43.3°C) or more, 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 (i.e. filter cycle durations or extended spa pump use beyond the
15 timeouts) and warm ambient temperatures.
*M0XX is a Message Code. Codes like this will be seen in the Fault Log
POSSIBLE FREEZING CONDITION
A potential freeze condition has been detected,
or the Aux Freeze Switch has closed. All water
devices are activated. 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.
