Hi, I have a 27' round with a 1.5 HP pump and am considering downsizing to a 1 HP pump, and I like the idea of a 2-speed.
I have been looking at the Pentair OptiFlo 1 HP dual speed, model #340071.
I notice that it comes with a twist-lock plug, which is what I currently have with my 1.5 HP single-speed.
Now, never having actually seen one of these pumps, I have been told that I'd need a timer such as the T106 to control the speeds. I'm not really understanding the control of speeds, though. I currently have a basic SPST timer to control on/off, which is in my basement and I have a standard 14/2 run from the timer out to my twist-lock outlet by the pool.
So I'm confused as to how the T106 would control speeds to this pump. It looks like there are 3 wires that would come out of the T106, according to this diagram: http://www.poolplaza.com/2-speed-timer-wiring.shtml But the new pump has a twist-lock plug?
