If all you want the fan to do is turn on and off, then yeah you can do that. Speed adjustments however are mechanical to the fan itself, and thus cannot be controller by the fan, again though, if you have speed controllers wired into a light/dimmer switch of some kind (thus it's electrical) then X-10 can be adapted for this purpose.
