Operating instructions

17
Light
Press the “Light” button to turn the light on and off. If left on, the light automatically turns off after
4 hours unless manually turned off prior to 4 hours
Mode
Mode is changed by pressing the “Warm” or “Cool” button, then pressing the “Mode” button.
Standard Mode is programmed to maintain the desired temperature. Note that the last mea-
sured spa temperature displayed is current only when the circ pump has been running for at
least 2 minutes. “Std” will be displayed momentarily when you switch into Standard Mode.
Economy Mode heats the spa to the set temperature only during filter cycles. “Ecn” will display
solid when temperature is not current, and will alternate with temperature when temperature is
current.
Sleep mode heats the spa to the set temperature only during filtration cycles. “Slp” will display
solid when temperature is not current, and will alternate with temperature when temperature is
current and will only heat to within 20 degrees of set temperature.
Option
The Option button is obsolete. It can be used for an extra blower or circulation pump. Pump 1
works as a circulation pump when run on low speed.
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 “Filc”). The default filter time is 2 hours.
To program, press “Warm” or “Cool”, then “Jets 1”. Press “Warm” or “Cool” to adjust. Press “Jets
1” to exit programming. At the beginning of each filter cycle the pumps purge for 5 minutes. The
only effect filter duration has is: 1) During the filter cycle, the pump never turns off, and 2) In
Economy and Sleep Mode, 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 pumps 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. Auz freeze sensor protection acts similarly
except with the temperature thresholds determined by the switch and with out a 4-minute delay
in turnoff. See your dealer for details.
