purification system you will find that your water stays fresh and clear with
significantly less chemical sanitizer usage. You will also probably be able to go

14.0 Error Conditions/Error Messages
Your spa has a self-diagnostic control system. The system will automatically
display the following if a problem is detected.
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 24-hour 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: 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 exces-
sively 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 fillups or during refills since tap water is often very
cold.
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
).
14.4 Panel Displays SN1
Open sensor (heater is disabled) or shorted sensor (spa is deac-
