We are looking to upgrade our bath exhaust fans with a timer switch in all of our apartment units (200,000+ units. In the recent past, I thought I saw an article or ad somewhere that had a switch that had a "hidden" timer that was adjusted then covered by the cover plate. Am I just dreaming or have you guys seen something like this too?
Any help would be GREATLY appreciated.
