Press the "Light" button to turn the light on and off. If left on, the light
automatically turns off after 4 hours.

Mode is changed by pressing the "warm" or "cool" then "Light Button".

that the last measured spa temperature displayed is current only when the

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 "
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. 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.
