13.0 Error Conditions/Error Messages
There are a number of unique functions designed into
your Sundance hot tub to protect it from damage and/
or to aid in troubleshooting. The indicator light located on the front
cabinet panel of the hot tub is an early detection system that will notify
you when the hot tub needs immediate attention. A solid white light
indicates that all operations are normal. A solid red light indicates that
immediate attention is required to clear or fix an error code. Following is
a listing of all the possible messages along with their meanings.
Always
insist on genuine Sundance replacement parts.
13.1 Summer Logic
When the actual hot tub water temperature reaches 2°F (1°C) above the
set temperature, the hot tub goes into “summer logic.” The circulation
pump will turn off automatically, if running, to avoid adding additional heat
to the water, eventually creating an overheat condition. This setting is not
user-programmable.
Note:
Summer logic does not take effect until the hot tub water
temperature reaches 95°F (35°C). This condition is more likely in
excessively hot weather. Remember, the hot tub’s ability to cool is
directly affected by the ambient temperature. An excessively hot
ambient temperature may prevent the hot tub from cooling down
because it’s fully insulated construction is designed to retain heat and
minimize operating costs.
13.2 Panel Displays COOL
Cool Condition - Temperature has dropped 20°F (11°C) below
the current set temperature. The circulation pump and the
heater have been activated to bring the temperature within 15°F (8°C) of
the set temperature. No corrective action is required!
Note:
This condition is common during first time fill ups or during refills
since tap water is often very cold.
13.3 Panel Displays ICE
Freeze Protection - A potential freeze condition has been
detected. No action is required. Water temperature is below 55°F
(12.78°C). Jets Pump 1, Jets Pump 2 and the circulation pump will activate
for 10 minutes, then turn off. Then the circulation pump and the heater will
activate for 10 minutes. The two cycles shall repeat until the water
temperature reaches 65°F (18.33°C). See “Winterizing” (page 43).
13.4 Panel Displays SN--1
Open sensor (heater is disabled) or shorted sensor (hot tub is
deactivated). The high-limit temperature sensor is not
functioning. Contact your authorized Sundance Spas dealer or qualified
service technician. The display will alternate between
“SN--1”,
scrolling
message
“HI-LIMIT SENSOR ERROR”
and the current water
temperature.
