DO NOT DIVE.
Mode
Mode is changed by pressing the “warm” or “cool” button, then pressing the “light” button.
Standard mode
is programmed to maintain the desired temperature. Note that the last measured
spa temperature displayed is current only when the low speed of pump 1 has been running for at
least 2 minutes. “St” will be displayed momentarily when you switch into Standard Mode.
Economy mode
heats the spa to the set temperature only during filter cycles. “Ec” will display solid
when temperature is not current, and will alternate with temperature when temperature is current.
Sleep mode
heats the spa to within 20°F/10°C of the set temperature only during filter cycles. “SL”
will display solid when temperature is not current, and will alternate with temperature when tem-
perature is current.
Preset Filter Cycles
The first filter cycle begins 6 minutes after the spa is energized. The second filter cycle begins 12
hours later. Filter duration is programmable for 2, 4, 6, 8 hours or for continuous filtration (indi-
cated by “FC ”). The default filter time is 2 hours.
To program, press “warm” or “cool” then “Jets.” Press “warm” or “cool” to adjust. Press “Jets”
to exit programming. At the beginning of each filter cycle the pump(s) purge for 30 seconds; the
pump purges for 5 minutes. The only effect filter duration has is: 1) During the filter, the low-
speed of pump 1 never turns off, and 2) In Economy and Sleep Modes, heating only occurs during
the filter cycle.
Freeze Protection
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 equipment stays on until 4 minutes after
the sensors detect that the spa temperature has risen to 45°F/7.2°C or higher. During freeze pro-
tection the heater will not be activated.
