Humidistat Performance

[Richard Brekne]

I am finding so far that on grands at least... you can "regulate" this range by
selecting different placements for the humidistat. Move it around until the
mean RH is where you want it... then there is this stability problem.
Personally I'd like to get the variance withing +/- 2.5 % RH.
