  1. Where you able to hook the relay of the controller straight up to the DI of the vfd. I thought that the VFD requires DC voltage and the relays on the controller are for 24 vac or 120vac

  2. I really appreciated you sharing this video, especially since I’m new to this industry. I agree with Michelle’s comment that the look of the honeywell tower fans look much more sleek than some of the other tower fans out there. Thanks for sharing this, as this helped a lot!
