I'm ordering a WhisperCeiling exhaust fan, based on all the rave reviews I've seen. I also want a timer switch if possible. Has anyone used the Fantech electronic timer that Wave Plumbing sells?

I like the simple idea of it; it has buttons for 10, 20, 30 or 60 minutes. I don't need a switch that also turns off a light, just a fan timer.

The website mentions that it needs a "neutral" wire within the junction box to install. Is that likely to be a problem? there is a fan/light switch there now that operates the old fan and a ceiling can light. I'll ask my contractor when I see him this week, but would like to get these ordered soon.

thanks so much!
