I would like to use the MP100 to ventilate two bathrooms, each 50 SF. What is the recommended method of controlling from from two locations? The installation guide only gives the scenario where one ON/OFF switch is used but there should be one in each bathroom for point-of-use control.
I must respectfully disagree with customer service.
For the proposed installation (multiple bathrooms, each able to turn on the fan), simply wiring standard SPST (typical on/off, or timers) switches in *parallel* will do what you want:
(a) if *anyone* turns it on, the fan starts
(b) it won't turn off until the *last* switch has been turned off.
You will still have to educate your family, since each user will need to turn their switch "on", even if the fan is already running (otherwise it may magically turn off in the midst of their shower).
