I particularly like to use Meastro dimmers for this! They make a neat effect as they fade up to the pre-set if left on. (only using the VC to control it) With a few dimmers you can kind of make a 'scene' out of it when operating the "Vacancy Sensor", (Not 'occupancy sensor'!) and all the dimmers come up to preset levels.
Shockme, VC uses NC contacts, the dimmer gets the same voltage, you dont or should not dimm the VC.
