SPA CONTROLS
Spa Behavior
PUMPS
On the Spa Screen, select a "Jets" button once to turn the pump on or off, and to shift between
low- and high-speeds if equipped. If left running, the pump will turn off after a time-out period.
The pump 1 low-speed will time out after 30 minutes. The high-speed will time-out after 15 min-
utes.
CIRCULATION PUMP MODES
The 24 hour circ pump operates continuously with the exception of turning off for 30 minutes at
a time when the water temperature reaches 3°F (1.5°C) above the set temperature (most likely to
happen in very hot climates).
FILTRATION AND OZONE
The system is factory-programmed with one filter cycle that will run in the evening (assuming the
time-of-day is properly set) when energy rates are often lower. The filter time and duration are
programmable. See Adjusting Filtration" section. A second filter cycle can be enabled as needed.
At the start of each filter cycle, the pumps will run briefly to purge the plumbing to maintain good
water quality. On spas equipped with 24 hour circulation systems the filter cycles cannot be set.
(See adjusting filtration section).
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 peri-
odically depending on conditions. If the temperature sensors detect a drop to below 44°F/6.7°C
within the heater, the pump will automatically activate to provide freeze protection. The equip-
ment stays on until 4 minutes after the sensors detect that the spa temperature has risen to
45°F/7.2°C or higher.
CLEAN-UP CYCLE
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 pump and the ozone generator will run for 30 minutes or more,
depending on the system. This setting can be changed. See "Preferences" section.
