Jacuzzi J - 355 Benutzerhandbuch

Your spa has a self-diagnostic control system. The system will 

automatically display the following if a problem is detected.

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 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.

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.

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 35).

Open sensor (heater is disabled) or shorted sensor (spa 

is deactivated). The high-limit temperature sensor is not 

functioning. Contact your authorized Jacuzzi dealer or 

qualified service technician.
