Error Conditions/Error Messages

Your spa has a self-diagnostic control system. The system will
automatically display the following if a problem is detected.
Summer Logic
When the actual spa water temperature reaches 1°C (2°F) above
the set temperature, the spa goes into "summer logic. " The circu-
lation pump will turn off automatically, if running, to avoid ad-
ding additional heat to the water, eventually creating an overhe-
at condition. This setting is not user-programmable.
Note: Summer logic does not take effect until the spa water tem-
perature reaches 35°C (95°F). This condition is more likely in exces-
sively 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.
Panel Displays COOL
Cool Condition - Temperature has dropped 11°C (20°F) below
the current set temperature. The circulation pump and the he-
ater have been activated to bring the temperature within 8°C
(15°F) of the set temperature. No corrective action is required!
Note: This condition is common during first time fill ups or du-
ring refills since tap water is often very cold.
Panel Displays ICE
Freeze Protection - A potential freeze condition has been de-
tected. No action is required. Water temperature is below
12.78°C (55°F). Jets Pump 1, Jets Pump 2 and the circulation
pump will activate for 10 minutes, then turn off. Then the circu-
lation pump and the heater will activate for 10 minutes. The two
cycles shall repeat until the water temperature reaches 18.33°C
