Hello Mike Saw your post and video on YouTube about your KB VFD’s. I have a thread going now about VFD’s. I have been looking at a Dayton VFD which turns out to be the exact VFD as the KB. I suspect KB makes VFD’s for Dayton? Anyway, I am going to run a 3/4 hp tubeaxial fan (also from Dayton). I just need basically an on/off and speed control. You kind of lost me with the jumpers you wired for the accessories? I don’t think I’ll need those options? Also, I don’t like the high-pitched whine noise some VFD’s make. Do you consider your VFD’s pretty quite? Thanks John
