• In 50A or 30A logic, the heater turns on for 10 minutes then turns
off. Then pump 1 and pump 2 turn on for 10 minutes, then turn
off. The spa will alternate between the heater and the pumps
being on and off until the spa gets out of the freeze condition.
note: The pumps cannot be manually controlled while the Freeze
condition is active. If a button is pushed, the error message will go away,
but will reappear if the spa is still in the Freeze condition 5 minutes later.
This error commonly occurs when the spa is first filled because tap water
is often very cold.
