Abstract
A system controls electrical power to multiple loads from both a central location and from local three-way controls. In one embodiment, the system includes means for sensing the power to each load. That sensing capability, in turn, permits the master to set all loads to the same power level, simultaneously, regardless of their original level. The local controls may be standard three-way dimmers or switches.
