Question about Pool & Spa
This was a direct replacement for the 2-speed Hayward superpump that we had installed when the pool was built. Nothing different other than having to figure out the low/high speed switch yourself and a change in the input pipe size from 1.5'' to 2.0''. Both motors are AO Smith units, but again the wiring panel is slightly different. I do not have any timer in the system.
Here's what I have:
50amp, GFI 230v, 3-wire connection (2 hot and 1 grd)
Wiring Panel on motor:
Grd is separate
Each have a screw and male connector, 3/4 has an additional male connector
Currently wired according to wiring diagram on motor:
White--------Goes inside to motor
Yellow-------Terminal 4 (my guess, diagram shows just line with no connection point)
I found a post on a pool site where they have the same pump but have their 230v connections to Terminal 1 & 2. They have high speed only and the same problem of figuring out how to wire the low/high switch.
I understand that you are not reducing voltage to the pump via the switch but are actually changing to a different winding. The switch wiring is baffling to me. I can only get low speed from the pump now which I believe is going through the white/black connection of the switch, flipping the switch to the black/yellow connection shuts off the pump.
I do not read anywhere that you have a 230V DPDT switch which you will need in order to select the high or low speed. You will have 6 terminalas on the switch. Line connections usually go to the middle set. Put put sides of one pole to the common terminal and put one of the other posts to the hi and the other to the low terminal. I prefer to use am on-off-on switch so the switch in the middle turns off the pump. Flip it one way for hi and the other for low. If you post your stock number from the two-speed motor I could give you a more accurate diagram if you need it. Generally, 1 is common, 2 hi and 3/4 low.
