9.0 Operating Instructions

The spa control system has automatic functions that operate
upon startup 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 segments 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 temperature setting of 100 °F (38 °C) and the spa is set to
skimming/heating mode "F0", "F1" "F2" or "F3" (page 19), the heater
will turn on and run until the water temperature 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.
4. Approximately two minutes after power is applied to the spa, the first
skimming/heating cycle turns on pump 1. In Palermo and Bahia models,
an automatic five minute "blow-out" function also activates pump 2 for a
period of five minutes to flush all lines. Then, after five minutes, pump 2
turns off and pump 1 continues to operate for the duration of the cycle.
Note: this function only occurs during the first skimming/heating cycle
each day.

9.1 Setting Water Temperature

The spa's thermostat provides optimum control of water
temperature. The temperature setpoint (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 ( + ) for 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 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 only operates in high speed. Both pumps have a twenty
minute default when manually activated.
