Been reading the forum for quite a bit now trying to get ready for the pool in a home we just purchased.
The pool has a 2hp pentair whisperflow pump right now for the pool, spa, and two small waterfalls.
The pump seems to work fine and is fairly quiet but living in Socal makes the electricity fairly expensive so I was looking to replace the pump with the Pentair 011018 VS pump.
The potential problem I see is that it has an Aqualink RS4 controller. This is a fairly simple controller so it doesn't have controls for variable speed pumps. I'd have to upgrade to an Aqualink Touch or iAqualink to get VS controls I believe.
Can the RS4 still work with the VS pump? When I press Spa or Pool button on the controller, will it just run a full max? Then I would go on the actual VS pump to vary the time and speed it comes on throughout the day for filtering?
Very new to pools so pardon the ignorance.
