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
temperature, a “Summer Logic” condition occurs that deactivates the circu-
lation pump and ozonator (if equipped). This safet
y feature cannot be
altered! The circulation pump and ozonator will remain off until the water
temperature cools to the set temperature (except between12AM-2AM when
the circulation pumps runs for it’s mandatory 2-hour “clean-up” cycle). To
help prevent a “Summer Logic” condition, it may be necessary to reduce
skimming/heating cycle and/or circulation pump run times in warm
weather.
9.4 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 10.2, page 25.
9.5 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 blower activate for one minute to circulate any water in the plumbing.
After 1 minute they both go off and Pump #1 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.
10.0 Programming Instructions
10.1 Adjusting Time of Day
The Sentry control system remembers the time of day even in the event of
a prolonged power outage. However, it may occasionally be necessary to
reset the time of day. For example: if you are not in the Pacific Time Zone
you will want to reset the time for your own time zone. (The system will
automatically adjust to and from daylight savings time.) To accomplish this,
press DISPLAY, MODE and DISPLAY within five seconds each. A number
representing the hour will be displayed, followed by AM or PM. The hour
will advance or decrease each time UP or DOWN is pressed within five
seconds. Then, press DISPLAY again to display the minutes. Adjust the
