Pool mode question

[jnojr]

When I run in pool mode with the vacuum attached, the pump is pretty quiet and indicates about 35 GPM / 2000 RPM / 500 W

If I remove the vacuum, the pump speeds up noticeably and sounds like it's in cleaning mode.

Should I change my pool mode programming to assume no vacuum?

Do you have a variable flow pump? Your signature indicates a variable speed (RPM) pump but what you describe sounds like a variable flow pump. What’s the part number of the pump?

If it is variable flow then what’s happening is you are changing the load on the system when you valve off the cleaner. This causes the pump to increase RPM’s to keep a constant flow rate.

jno,

Just one of the reasons we do not recommend running in the VF mode... VS, works better for most people.

Thanks,

It's an Intelliflo VSF P/N 350305

Is that a switch I can flip and walk away from, or would changing that affect other aspects of the programming?

Yeah, you’re definitely operating in variable flow mode. I have an older version (2013 model) variable speed IntelliFlo so there’s no flow control point. But I imagine that your pump can be operated in either mode, constant RPM or constant flow, and there’s just a setting in either the IntelliTouch or on the pump to specify which control point you want to use.

Now is a good time to read through the arcane language of the documentation you have....Pentair-speak is about as easy to understand as ancient Egyptian Hieroglyphics.....

If you have ScreenLogic, show us this page from your system...

Ok, now what???

Matt,

So I wrote a whole page asking the OP why the pump type was VS and not VSF...

And then I realized it was you...

I don't, my system is from 15 years ago, I'd need to find the screen on my inside remote and snap a picture... when I get home.
