I am remodeling two bathrooms and I would like to put fans with heater and lights in the bathrooms. I have only seen 110 CFM rated fans and since the bathrooms are large I am thinking that installing an in-line fan that would be connected to both bathrooms would be appropriate.
Is there a way that I can control the in-line fan from the two bathrooms (where the individual bathrooms switch would also turn on the in-line fan also).
