@Pool Clown is a knowledgeable fella and he would certainly know.
I'm confident that the pump speeds will fix your issue and really there's no reason why your spa speed should be lower than pretty much any of your other circuits.
Is your filter dirty? That seems like a relatively high speed for such a low flow.
@mknauss is very correct about the robot. Another option that's a little less expensive is automating your pool cleaner valve so that that's the only thing open when you're pool is in cleaner mode... you may have already done this because I recall seeing your pool equipment setup and you had a gaggle of valves all over the place but I don't recall at the moment
Thanks Brian. Appreciate the advice as always. If in fact, the Manual OP Priority is supposed to prevent the schedule from interrupting the spa use as @Pool Clown has suggested in that earlier thread, then I can confirm 100%, the Manual OP Priority feature is NOT working with the IntelliCenter currently. I would really like to hear from any members that can confirm that it is working like that on their ET/IT automation systems. I am going to try to confirm all of this with Pentair Tech Support this week.
Filter is not too dirty yet. Only about 5 psi above the "right after backwash" starting psi.
As far as setting the pool cleaner/skimmer valve to the pool cleaner full open position, I guess I could do that and then run the pump at a lower speed. I would also need to close off the spa skimmer as well. I guess I could have two daily programs. One for pool cleaner ONLY, the other for pool and spa skimming ONLY. I'll have to weigh the advantages and disadvantages of changing up some of the CIRCUIT GROUPS (macros) / schedules. That issue would be a lot easier if I were not presently restricted to ONLY two valve positions that I can use. I'll have to wait for the Pentair OTA firmware release so I can use more than two valve positions. In the meantime though, I would really like to find out for sure about the Manual OP Priority deal. I'll let you know what I find out (if anything) from Pentair.
Thanks again for the input.
