13.0 Error Conditions/Error Messages

There are a number of unique functions designed into your spa to protect
it from damage and/or aid in troubleshooting. Refer to Sections 13.1-13.9
below for a listing of all possible error messages and their meanings.
Always insist on genuine Sundance replacement parts.
13.1

Summer Logic

When the actual spa water temperature reaches up to 2°F
(1°C) above the set temperature, the spa goes into "summer
logic." The circulation pump will turn off automatically
to avoid adding additional heat to the water, eventually
creating an overheat condition. This setting is not
user-programmable.
Note: The summer logic does not take effect until the spa water
temperature reaches 95°F (35°C). This condition is more likely in
excessively hot weather. Remember, the spa's ability to cool is directly
affected by the ambient temperature. An excessively hot ambient
temperature may prevent the spa from cooling down because it's
fully insulated construction is designed to retain heat and to minimize
operating costs.
13.2

Overheat Condition

WARNING: RISK OF HYPERTHERMIA (OVER-HEATING)
!
CAUSING SEVERE INJURY, BURNS, OR WELTS.
DO NOT ENTER SPA WATER! Water is too hot. Overheat
protection. Heater is deactivated. Spa water temperature is
above acceptable limits. When the actual water temperature
is approximately 2°F (1°C) above the set temperature, the
circulation pump will stop operating to reduce (frictional) heating. To
correct condition, remove spa cover to speed cooling. (CAUTION! Never
leave spa uncovered when children are present!) If condition persists,
contact your authorized Sundance dealer.
