When in a Summer Logic condition is active (see note below), the filter/circula-
tion pump will turn on for all programmed filter cycles.
Summer Logic: In warm weather, the water temperature in the spa may
exceed the set temperature. This condition may occur due to heat transfer-
ence from the filter/circulation pump and jets pumps. If the water temperature
is higher than 95°F (35°C) and rises two degrees above the set temperature,
a “Summer Logic” condition occurs that deactivates the filter/circulation
pump and ozonator (if equipped). This safety feature cannot be altered! The
filter/circulation pump and ozonator will remain off until the water tempera-
ture cools to the set temperature (except between
9:00 - 11:00 AM when the
filter/circulation pump runs for its mandatory 2-hour cycle). To help prevent
a “Summer Logic” condition, it may be necessary to reduce filter/circulation
pump cycles run times in warm weather.
