We store Christmas stuff, luggage and other stuff up there and never had any problem with dampness.
Now that we are getting old, I'll have to clean all that stuff out, while I'm still able.
The basement is where we have all the dampness.
In the summer, I'll try leaving the ventilation system in heating mode,
so both warm (above 66F) & hot (dry) air is pumped into the basement.
That will keep the air moving in both the attic and the basement.
Using the CAI program, I can limit how warm the basement gets,
just by shutting off the attic's blower. Or both blowers.
It if starts up at 66F in the mornings, a good bit of air can be moved
before the attic heats up to the 100F plus range.
In the summer, I think it would be nice to have the basement in the mid 70s.
If the system tries to pump down 120F air, I can just pull out the shopping bags,
to start pulling in a mixture of hot and outdoor air..
