This is far superior to the unintuitive JEP-R controller that came with the house when we bought it! The fact that you can only set 2 speeds on the JEP-R makes 24-hr pump running inefficient. I use a 2 hour run at 2500 RPM, a 7 hour run at 1800 and a 15 hour run at 1000 to keep my pool water crystal clear!
