Dewitts Spal Brushless Fans Problem

[dhutton]

What if you disconnect the override from the binary switch? Do the fans operate normally?

Have you tried connecting to the other side of the binary switch?

I had something strange happen with the old Entropy fan controller and had to put a diode in series with the signal from the binary switch to get it working right when I connected it to the AC sense input on the Entropy controller.
