After 18 years of mostly hassle free service, my old Pentair WhisperFlo (2HP 2 Speed) finally went to the great pool equipment scrapyard in the sky. So I decided to replace it with a new Pentair SuperFlo VS, and I have a few of questions in regards to wiring. The old system ran through an analog timer to cycle the filter in low speed mode and an "air switch" to activate the high speed and heater function.
Pool Information: 1000 Gallon - In ground hot tub
1) The old 2 speed motor had 4 wires attached to it: "L1" Black, "L2" Blue, "GND" Green and "A" Brown. I know L1, L2, and GND are my 220 supply and am clear on their connection. However, what about the "A"? I assume this was the connection for the low-speed function and is eliminated with the new VS motor.
2) Can the "air switch" be removed? I assume I will now be using the control panel on the pump to select a high speed setting and that this higher flow rate is what activates the heater.
3) Finally, since the new VS motor has programming and speed control I assume that the analog timer can be completely removed.
