Initial Start-up
When rst powered up, your spa will perform a self-diagnostic check and then automatically go into priming
mode. The topside will display PR to indicate this. Priming mode will be active for less than ve minutes. When
the spa has nished priming, the heater will be activated and the water temperature will be maintained in stan-
dard mode. The spa will automatically heat to 100°F (37.5°C) at start-up until you change the set temperature
as listed in the “Temperature Adjustment” section below.
These instructions will describe features and options
that your particular spa may not be equipped with.
Temperature Adjustment
80°F - 104°F (26.0°C - 40.0°C)
The start-up temperature is set at
100°F (37.5°C). The last measured
temperature is constantly displayed
on the control panel. Note that the last
measured spa temperature is displayed.
The displayed temperature will be updated
when the pump has been running for at least two
minutes.
Press the “UP” or “DOWN” buttons once to display the
set temperature. Each time either button is pressed
again, the set temperature will increase or decrease
depending on which button is pressed. After three
seconds, the control panel will automatically display
the last measured spa temperature.

When time hasn’t been programmed, the “TIME” icon
ashes. To set the time, press the “TIME” button and
then the “MODE/PROG” button. Use the “UP” and
“DOWN” buttons to adjust time. See the next page

Jets 1 and Jets 2
Press the “JETS 1” button once to turn pump 1 on
or off and to shift between low and high speeds if
equipped. If left running, the low speed turns off af-
ter two hours and the high speed turns off after 15
minutes. On non-circulation systems, the low speed of
pump 1 runs when the blower or any other pump is
on. It may also activate for at least two minutes every
30 minutes to detect the spa temperature and then
to heat to the set temperature if needed, depending
upon the mode. When the low speed turns on au-
tomatically, it cannot be deactivated from the panel;
however, the high speed may be started.
