Edit...posted this question on INYO pools but no answer yet.
You can also email them. They usually reply to questions but takes a few days.
I have an inyo pump with that motor and love it so far, Only had it for about 1 1/2 years..Supper quiet and seems efficient
I have about the same pump setup and have started sending all water to the spa and Returning 80% from skimmers and rest from main drain. Have it at 1800 rpm .
I don’t use but one program but just set it to run for 16 hours and cut off 8 using the programs
