9.0 Operating Instructions

The spa control system has automatic functions that operate upon start-
up and normal operation to protect the system. Upon power up, the
readout displays the following information:
1. Control panel displays current software release
(e.g. 3.56), then;
2. Control panel displays "888" and all indicator LEDs
are lit, permitting visual inspection of all display seg-
ments and indicator lights for proper operation.
3. After the initial start-up sequence ends, the actual
water temperature is displayed. If water temperature
at this time is less then the factory default tempera-
ture setting of 100°F (38°C) and the spa is set to
either standard filtration/heating mode "F0-F3", the
heater will turn on and run until the water tempera-
ture rises to the factory setting, then turn off. Note:
it is common for the heater to turn on after the spa
is first filled because tap water is often very cold.

9.1 Setting Water Temperature

The spa's thermostat provides optimum control of water tem-
perature. The temperature set point (set temperature) can be
adjusted from 65°F to 104°F (18°C to 40°C). To raise the set
temperature, press the WARMER ( + ) button. To lower the
set temperature, press the COOLER ( - ) button. Note: The
first press of either WARMER ( + ) or COOLER ( - ) button
displays the set temperature.

9.2 Activate Pumps

The JETS 1 button activates the functions of the main
2-speed jets pump. The first press activates jets pump 1 in
low speed, the second press activates high speed, and the
third press shuts the pump off. The JETS 2 button controls
jets pump 2 which operates only in high speed. Both jets
pumps have a twenty-minute default when manually acti-
vated.
