13.3 Optional CD Ozone Water Maintenance System
If you have elected to have your spa equipped with the optional Jacuzzi
Premium CD Ozone water 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 longer between complete spa drainings. The
CD ozone unit operates in conjunction with the circulation pump.
13.4 Summer Logic
When the actual spa water temperature reaches up to 2 °F
(1 °C) above the set temperature, the spa goes into “sum-
mer logic.” The circulation pump will turn off automatically
to avoid adding additional heat to the water, eventually cre-
ating an overheat condition. This setting is not user-pro-
grammable.
Note: The summer logic does not take effect until the spa water tempera-
ture 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 to minimize operating costs.
14.0 Troubleshooting - Display Messages
There are a number of unique functions designed into your Jacuzzi Premium
spa to protect it from damage and/or to aid in troubleshooting. Following is
a listing of all the possible messages along with their meanings:
MESSAGE MEANING
Overheat Protection (Heater is deactivated, pump’s
low speed is activated). Water temperature is
above acceptable limits. Do not enter the water!
When the actual water temperature is approxi-
mately 2 °F (1 °C) above the set temperature, the
circulation pump will stop operating to reduce
(frictional) heating. Remove spa cover to speed
cooling (CAUTION! Never leave spa uncovered
when children are present!) See “WATER IS
TOO HOT” on page 41. If condition persists,
contact your authorized Jacuzzi Premium dealer.
