The system you're describing is definitely the simpler approach. The fan can even be taken out of the control equation entirely. Just run it at constant speed and have a leak path for the airflow when the damper is fully closed. Kind of a brute-force approach, but highly attractive for its...

Different versions of the code for different setups is definitely out. I think that everyone greatly appreciates all the time you put into development/improvements/features, and it shouldn't be wasted on maintenance nightmares. I don't have anything laying around to repurpose, so hobby servos...
