during lights on i want to have my extraction fan running full, but during lights out id like to have it run minimum just to keep negative pressure and keep humidity down.

the only thing ive thought of is having the fan power cord split into 2 male ends, 1 plugged into a speed controller set at minimum, the other just plugged in normal. then id have each power source on timed relays. i dont really like the sound of that though in case of accidental overlap.

anyone know how to do this? or a product that would do the trick? thanks...

This will do everything that you want. I've been using mine for a couple of years and it hasn't missed a beat.

I was about to recommend the Titan Mercury 4 controller, which the controller rives posted is an exact clone of. I won't get into who copied who, but either one will work.

From the looks of them, I'm not sure anyone "copied" anything. They appear to have come off the same assembly-line until they got to the labels!

I wouldn't go so far as to say "all fans", but I'm running a FanTech.

That's why I wasn't going to bother lol

I'm running two of the Titan sticker variants on Fantech FG8XL's, and two on CAP Valueline Fans, all 4 have been working without a problem...temps always at 75F right where I set them.
