3way (DPDT) timer switches
Well, in order to work, that means that the vents to the
two bathrooms have to be interconnected, which isn't
a good idea.
Why is it not a good idea... batrooms are back to back.. both hoses
take air out of bathroom.. go into a fan unit in the attic and it blows
the air out the top of the roof.. not understanding the problme with
that.. what am I missing. .
