Its been awhile since Ive looked at this. I actually dont have a feed back loop but i was going a light to indicate when the fans are on and a switch for the controller but never got around to it. I 'could' accidentally run taurus high and low with the switch and controller but I never use high via switch unless i have some sort of issue.
