times, while pump 1 and pump 2 turn on for 10 minutes and then
off for 10 minutes. The pumps will alternate on and off until the
spa gets out of the freeze condition.

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.
