fan controller question

There's the wiring diagram. Other than that you just have to set it to be a dual speed fan and everything works well. I recommend 200 on/195 off for low speed and 210 on/205 off for high speed with a 185 thermostat.

goldduster318 I have a question about your wiring diagram, I think I have it wired correctly however now I’m second guessing my work

The wires on the fans labeled A and B which color is which? I have the blacks as A and the green wires as B but that isn’t how they are shown in your diagram b in your diagram would be black and A would be green. See my linked pic below
