SPA BEHAVIOR
FREEZE PROTECTION
If the temperature sensors within the heater detect a low enough temperature, then the pumps
automatically activate to provide freeze protection. The pumps will run either continuously or
periodically depending on conditions.
CLEAN-UP CYCLE (OPTIONAL)
When a pump is turned on by a button press, a clean-up cycle begins 30 minutes after the pump
is turned off or times out. The heat/filter pump and the ozone generator will run for 30 minutes or
more, depending on the system. If the spa has a 24hr circulation pump which performs as the heat
and filter pump, the cleanup cycle will not apply as the 24hr circulation pump provides constant
filtration. On some systems, you can change this setting. See the Cleanup Cycle section in
Additional Settings.
