the ceiling. I want to preserve the speed controls, if possible, but I'd

dust (yea, I do have a DC plumbed to everything but 'fines' tend to get
away). The real problem is that the AC access is on the ceiling where the
lights are plugged in. If I could mount the timer to the bottom of the fan
I will be able to reach it without a ladder. I would prefer a self
contained unit so that I don't have to get into running conduit and
installing a box for the typical bathroom type timer. Do any of you folks
have any experience with such a device?
As always, TIA!
