Standby Mode
The spa can be disabled when the filter needs to be serviced or when changing/servicing a JetPak™. Press the
“Warmer” or “Cooler” button, then the “Light” button, and the display will show “
StbY
.” All spa functions will be
disabled except for auxiliary freeze control. Press any panel button to resume spa operation.
Freeze Protection
If the temperature sensors detect a drop to 40°F within the heater, then pump 1 (and the heater if necessary) will
automatically activate to provide freeze protection. The equipment stays on until the sensors detect that the spa
temperature has risen to within 15°F of the set temperature. The pump will purge for 30 seconds to 2 minutes at
the end of the freeze condition.
