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

(e.g. 3.57), 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 (page 28), 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).

A. Press and hold the WARMER ( )

button then;

B. Press and hold the JETS 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 has been activated, the white 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.

10.2 activate Jet pumps

The control panel JETS 1 button activates jets pump 1. The

first press activates low speed, the second press activates

high speed, and the third press shuts jets pump 1 off. The

JETS 2 button activates jets pump 2. The first press activates high

either pump will automatically turn off after 20 minutes.
