Using Filter Mode in conjunction with Features Mode

IntelliFlo will start and stop at the times you program for filter cycles 1-4, however the parameters you
set to operate features in Features Mode (Feature 3-9 only) supercede the filter cycle parameters you
set in Filter Mode. As seen in the example below, cycles programmed in Feature 3-9 will override the
filter cycles programmed in Filter Mode, however when the feature cycles are completed, IntelliFlo will
recalculate the flow rates and durations necessary to complete the interrupted filter cycles, and will resume
them at the point where it left off. This may result in a filter cycle finishing early if the volume of water
required to complete the cycle is reached early because the pump was running to operate a feature.
Example: Filter Cycle 1 is programmed in Filter Mode for a 80 m
perform 1 Turnover with a start time of 1:00 and a stop time of 11:00.
InterlliFlo calculates the flow rate to achieve this at 8 m
Feature 3 is programmed to start at 4:00 and run at 15 m
(15 m
The filter cycle begins at 1:00, as scheduled, and runs at a rate of 8 m
time, Feature 3 overrides Filter Cycle 1 and runs until 8:00 at a rate of 15 m
When Feature 3 stops at 8:00, IntelliFlo has pumped 84 m
15 m
As a result, IntelliFlo does not resume Filter Cycle 1 and treats it as completed at 8:00,
although it was originally scheduled to run until 11:00.
Note: Feature 1 and 2 in Features Mode do not have time-of-day functions and do not affect the
filter cycle time (See "Feature 1(2) Mode" on page 20, and "Feature 1 and 2" on page 34.).
will not factor in the active time for Feature 1 and 2 in its recalculation of the reduced filter cycle time in
the example above.
