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. 3.60), 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 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.
