A: The DH100W fits single-gang box. if you currently have a single gane box that houses your switch, then yes.
A: If you have a triple gang box I do not think it will fit properly. I doubt you can get a plate to cover the other two switches with this in place. You may be able to cut a cover plate to make it work but it would not likely have a good appearance and may not meet code. I think it needs its own single gang box. You may be able to mount a new single box near the device it is controlling and reroute the wires there and leave the existing switch in the on position at all times. Just my opinion. Mine works well. It is in the garage to exhaust excess moisture primarily when we come home with snow covered cars.
A: Yes, it will.
A: It certainly should. There may be other features on the fan that would not be activated with this, but as to turning the fan on when humidity is high and off when the humidity is lowered it should be just fine.
