running, but no apparent change of operation will occur. However, when
"Economy" mode is selected (sec. 10.3, page 36), the heater activates
only during a programmed filter cycle.
When in a Summer Logic condition is active (see note below), the filter/
circulation 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 transference 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 optional ozonator (if
equipped). This safety feature cannot be altered! The filter/circulation
pump and ozonator will remain off until the water temperature cools to
the set temperature (except between 12AM-2AM when the filter/circu-
lation pump runs for it's mandatory 2-hour cycle). To help prevent a
"Summer Logic" condition, it may be necessary to reduce filter/circula-
tion pump cycles run times in warm weather.
