Jets 2 (optional)
If your system has a pump 2 installed instead of a blower, it behaves exactly like a blower would.
Light
Press the "Light" button to turn the light on and off. If left on, the light automatically turns off after 4
hours.
Mode
Mode is changed by pressing the "Temp" or "Set" button, then pressing the "Light" button. Standard
Mode is programmed to maintain the desired temperature. Note that the last measured spa tem-
perature displayed is current only when the pump 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
temperature 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 (indicated
by "FC"). The default filter time is 2 hours. To program, press "Temp" or "Set," then "Jets." Press
"Temp" or "Set" to adjust. Press "Jets" to exit programming. The blower purges for 30 seconds at
the beginning of each filter cycle. The low speed of the pump runs during filtration and the ozone
generator (if installed) will be enabled.
Freeze Protection
If the temperature sensors detect a drop to below 44°F/6.7°C within the heater, the pump
and blower 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.
In colder climates, an optional additional freeze sensor may be added to protect against freeze
conditions that may not be sensed by the standard sensors. Aux freeze sensor protection acts
similarly except with the temperature thresholds determined by the switch and without a 4-minute
delay in turnoff. See your dealer for details.
