Hi,
So my spa pump bearings were going out and I had an extra single speed Pentair Whisperflo pump that I connected to the spa, but it only has 3 leads. I connected the white, black and green, and it works fine on the single speed setting, but when the controller cycles through its running algorithm to the two speed setting it returns an error and halts, presumably because the red wire is not connected.
I don't see a make or model number on the controller. The previous pump was AO Smith 3hp, 230v, 3450/1725 rpm pump. The Pentair is 2hp, 230/115v, 3450 rpm pump.
Is there a way to safely connect the red so it cycles through without halting? I would like to make this work because a bearing kit is $50 plus tools I will need, whereas this was few bucks for fittings.
Thanks for any help.
