I re-read ken's post and think he should call factory. The way I understood these fans is that they default to high but can run at low speed if the sensors are cool enough. (Have no reason to believe that off could be an option as well).

What Ken said that it came on and ran at "high" for a while and then cut off. That does not sound right to me. I would expect it to start at high then low then (possibly) off.

Can anyone verify if the fans are supposed to have two speeds?
