I have 1 exhaust fan for a house. This fan is ducted for the bathrooms and whole house fan. I have 3 timers for which it can be started from. 2 will be located in bathrooms and 1 in laundry room with a 24hr timer. How would this be accomplished? The 2 bathroom timers will be a pushbutton type so they can choose 10 min, 15, 30 etc.

I would imagine the fans would be wired similar to a 3 way - 4way - 3 way switch?

3 timers 1 fan.

Thanks guys

Mike
