Thanks Stormin for the effort! Really appreciate it!


I learned about the damper from the thread. Didn't know I had one and
don't shut it off. Have to do that next summer.

I don't measure humidity but Aprilaire seems to work OK but things do
dry out in the winter. I put in a new pad every year as old has a lot
of salts precipitated around it although I think it could work for a
couple of years without change.
