room climate control

[Andrew and Rebeca Anderson]

I suspect that Jurgen's concern isn't humidity cycling but is the 
increased possibility of rust.  You can get switch units for bathroom 
lights and fans that control 120v 15 amp circuits.  I haven't looked 
into accuracy here, but if acceptable they could control a unit that 
is always on.
