10.0 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 then;
2. Control panel displays “888” and all indicator LEDs are lit, permit-
ting 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 than the fac-
tory default temperature setting of 100°F (38°C) and the spa is set
to either standard filtration/heating mode (Sections 11.1-11.2, page
26), 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.
10.1 Setting Water Temperature
The spa’s thermostat provides optimum control of water
temperature. The temperature set point (set temperature) can
be adjusted from 65-104°F (18-40°C). To raise
the set temperature, press the
WARMER
( )
button. To lower the set temperature, press the
COOLER
( ) button. The first press of either
WARMER
( ) or
COOLER
( ) button
displays the set temperature. To access the
overtemp feature that allows the spa to reach
106°F (41°C) follow the steps below (Figure 1).
WARNING:
RISK OF HYPERTHERMIA (OVER-HEATING)
CAUSING SEVERE INJURY, BURNS, WELTS OR DEATH!
Water temperature in excess of 104°F (40°C) may injurious to
your health.
!
A. Press and hold the
WARMER
( ) button then;
B. Press and hold the
JETS 1
(
1
) button at the same time for 2
seconds. You will see the temperature rise to 106°F (41°C) on the
LED display. To lower the temperature, press the
COOLER
( )
button.
C. When the overtemp feature has been activated, the decimal point
after the last digit will flash on and off every second as an indicator
for being in the overtemp mode.
Note:
Once the temperature goes below 104°F (40°C) and you would
like to raise the temperature to 106°F (41°C) again, you will have to
repeat the steps above.
