Freeze Protection
If the high-limit sensor detects 40°F at the heater, then all equipment is automatically activated to provide freeze protection. This is a
normal spa function; no corrective action is necessary. The equipment stays on until the sensor detects 45°F at the heater. Freeze
protection is enabled regardless of the status of the spa. In colder climates, an optional additional freeze sensor may be added to
protect against freeze conditions. See your dealer for details.
Diagnostic Messages

heater, the spa will shut down. When the heater cools to 110°F, press any button to reset the spa. If the spa will not reset,
then shut off power to the spa and call your dealer or service organization.
