Operating Instructions; Setting Water Temperature - Sundance Spas 780 series Owner's Manual

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. 3.60).
2. Control panel displays "888" and all indicator LEDs are lit,
permitting visual inspection of all display segments and indi-
cator 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 factory default temperature setting of 100°F
(38°C) and the spa is set to either of the standard filtration/
heating modes (page 29), 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 filtration/heating cycle turns on pump 1. For 2 pump 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 filtration/heating cycle
each day.

adjusted from 65-104°F (18-40°C). To raise the set
temperature, press the WARMER (
lower the set temperature, press the COOLER
