IntelliFlo Installation and User’s Guide
Filter Mode (Continued)
Using Filter mode with Features mode
IntelliFlo will start and stop at programmed filter cycles 1-4. The filter cycles can be overridden by
“Feature” (3-9 only) as shown in the example below. This may cause the required filter volume to be
achieved earlier.
The “Feature” function is allowed to take control during “Filter” mode. When the feature function stops,
IntelliFlo will continue in “Filter” mode. If only Feature 3-9 is active during a filter cycle, IntelliFlo will
calculate a new filter cycle.
Example: The IntelliFlo was suppose to run in Filter mode from 1:00 to 11:00 to turnover
10 GPM for 10 hours (10 GPM 10 Hours= 6 kGal).
But because Feature 3 has been running 20 GPM for 4 hours (20 GPM 4 Hours= 4,8 kGal),
the IntelliFlo must stop at 8:00 because; 10 GPM* 3 Hours + 20 GPM 4 Hours= 6,6 kGal.
“Feature” 1 and 2 do not have time-of-day functions and do not affect the filter cycle time. The active time
for “Feature” 1 and 2 will not be calculated into the reduced cycle time as shown in the above example.
