MY PB is supplying VS pump and when I brought up the VF, he didn't even know it existed.
He talked to his rep and stated that he believes that I would be much happier with VS pump.
He also told me that the VF is an older design, and that since the VS came out, Pentair sells mostly VS pumps.
I talked to TechSupport today and was told that there were some limitations to VF such as:
1. If adding/using solar panels, the additional head will screw with VF logic and shut the pump down.
2. If pressure on the filter goes up 10PSI from initial setting, the pump will shut down. BTW, I'm OK with that as that's a good reminder to clean the filter.
3. The schedule/configuration/adjustments are more involved/complicated in VF pump, whereas in VS is a simple timers/schedules/RPM settings.
To the last point, I will be using IntelliTouch, with data bus, which I'm told by TS will put the pump's programs and LED in an 'Inactive' state and all the programming will be done thru IntelliTouch and SL2, or in my case the Autelis.
With all that said, can Autelis do all the programming that's involved in VF configuration?
Having never owned a pool and never be exposed to any of the equipment (hardware and software), I wanted what I thought was a more logical solution, which in my mind is to control pools gallons moved per minute/hour/day.
I don't think I care that the pump is running at 1000RPM vs. 1100RPM as long as it moves the amount of water to accomplish the x# of changeovers per day.
I understand that there are tables and conversion charts to calculate RPM into GPM, but why would one choose to do it when there is a solution that gives you volume right out of the gate, AND can compensate for variables such as clogging filter.
What would/did you do and what drove your decision?
I'm not that concerned about the price delta if the VF pump gives me more reliable results in maintaining consistent flow to my water shooters, slide, etc.
