Hi,
I don't think it is wise idea because even if two 'stats are same model
they won't work in synch. creating undefined results. As an EE, if it
has to be done I have an idea. I can make Boolean logic circuit
to make only one 'stat is in control, not both.

Sure, you can Boolean all you want with ans, ors, nots, but what you
will not accomplish is controlling the ducts with said setup.
