Hi Nik, thanks for writing in. This fan is meant to be vented to two locations maximum, since it can only provide a maximum of 270 CFM. You will likely want to go with a larger fan in the case that you will be adding a third vent off of the unit.
In some cases yes, however depending on how the fans are installed sometimes multiple fans are not effective. We would suggest consulting with an HVAC professional to review the specific application.
I wired the fan using a three way switch in each room. Sent from my iPhone
You can turn the fan on from either bath. (Wire in parallel) However, the fan will run as long as either one or both fan controls is activated. If you want individual control (on and off) you would have to purchase another system. They are available but more expensive. Jeff Musson
You can make a dual control for this fan. Assuming you are simply switching them on and off (no timer): Make it a 3-way circuit so changing the position of the switch in either bathroom will turn it on or off. You would do this the same way as a light controlled by two switches. You can get help with this in any hardware/home supply store. If you want to use timers, it is a little trickier... You would install a timer in each bathroom that either will turn the fan on. They would be wired in parallel so if either timer turned the fan on, it would operate. You would not be able to turn it off from the other bathroom. There are some important rules to this because you will be back-feeding the other switch when one room turned the fan on. That is a very unusual wiring situation that could be dangerous to someone working on the wiring (not during normal operations of the fan). You would have to make absolutely sure both timers were on the same circuit (controlled by the same single circuit breaker). This arrangement would have the fan operating if either timer was turned on. One note on this setup is to make sure the timers will work OK when there is a backfeeding situation. Many of the new electronic timers will probably not work. The best thing would be the old fashioned twist timers. Basically, you will be installing each timer as if it was controlling the fan and simply wiring them both to the same fan. The same hardware/home supply store can help you with the wiring instructions for this. Hope this helps. Stan
I puzzled over this one for a while, but I finally realized the two switches (one in each bathroom) need to be wired in parallel. See this link for a diagram: http://www.electricaltechnology.org/2012/11/how-to-wire-switches-in-parallel.html I used a timer switch that allowed 10/20/30/60 or Hold (on like a light switch) in each bathroom. It may require a little rewiring and if you have any doubts, call an electrician. The switches are set up so that as long as either one is on, the fan is on. If someone's in the shower in one room with the timer on 30 minutes and someone else has the other timer on 10, then the fan will stay on even when the 10 minute timer goes off in the one room. When the other timer goes off after 30 minutes, in the other room, the fan goes off. The timers have a light to tell you they are on. Sometimes those remote fans can be very quiet. You can use plain switches, but having a light on it when the powers on is helpful. Good luck. Greg
