Error Conditions/Error Messages

Your spa has a self-diagnostic control system. The system will
automatically display the following if a problem is detected. Always
insist on genuine Jacuzzi replacement parts.
14.1

Summer Logic

When the actual spa water temperature reaches 2°F (1°C)
above the set temperature, the spa 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 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 minimize operating costs.
14.2

Panel Displays COL

Cool Condition - Temperature has dropped 20°F (11°C)
below the current set temperature. Jets pump 1 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. "COL" will only appear when the spa is
in Economy mode.
14.3

Panel Displays ICE

Freeze Protection - A potential freeze condition has been
detected. No action is required. Jets Pump 1 and heater will
activate to circulate and warm water through the plumbing until spa is out
of danger. See "Winterizing" (page 38).
Note: "ICE" will only appear when the spa is in Economy mode.
14.4
