Multi-port bath fans
I have two bathrooms without exhaust fans and a multi-port fan in a box in the basement. The bathrooms are stacked in a cape. The upstairs ceiling is sloped with a small attic area above the flat segment.
Assuming I can come up with a way to run the ducts from each bathroom to the fan, how should it be wired? Should the fan turn on whenever either light switch is turned on? Should there be some sort of timer involved?
There’s no ventilation in the house — it’s heated hydronically.
Thanks in advance,
