Venmar (Vanee/Broan) ERV / HVAC controller output

Looks like it works! this is very cool thanks so much.

For the record I did some tests and looks like recirc mode in this implementation will force full speed even if the previous mode was minimum speed of manual. I previously had the touch controller (before it blew up because of an electric surge) and could chose from min, medium, high speed. I don’t think that’s possible from the basic controller though. Any idea on how to implement it?

I plan to at least try to repair my “old” touch controller. If so I could run some more scans.
