Preset Skimming/Heating Cycles; Clean-Up Cycle - Jacuzzi 2003+ ProTech LCD Series Owner's Manual

Summer Logic: In warm weather, the water temperature in the hot tub may
exceed the set temperature. This condition may occur due to heat transfer-
ence from the main pump and 24-hour circulation pump. If the water tem-
perature is higher than 95°F (35°C) and rises two degrees above the set tem-
perature, a "Summer Logic" condition occurs that deactivates the circulation
pump and ozonator (if equipped). This safety feature cannot be altered!
The circulation pump and ozonator will remain off until the water tempera-
ture cools to the set temperature (except between12AM-2AM when the cir-
culation pumps runs for it's mandatory 2-hour "clean-up" cycle). To help pre-
vent a "Summer Logic" condition, it may be necessary to reduce skim-
ming/heating cycle and/or circulation pump run times in warm weather.

10.4 Preset Skimming/Heating Cycles

Your hot tub comes with four 30-minute skimming/heating cycles already
programmed in, beginning at 6:00 a.m., noon, 6:00 p.m., and midnight.
You can easily change the start time, or the cycle length for any of these
cycles to suit your individual needs by following the steps in section 1 1.2,
page 30.

10.5 Clean-Up Cycle

The clean-up cycle is once per day in both Standard and Economy mode at
12:00 PM for two minutes. This is not user programmable. Pump #2 (and
J-380 pump #3) and blower activate for one minute to circulate any water
in the plumbing. After 1 minute they go off, then Pump #1 turns on and
runs for 1 minute. If the skimming/heating cycle is also set at 12:00 PM,
pump #1 will continue to run for the duration of the cycle.
