Abstract
A wall mountable control panel for controlling power levels delivered to electrical loads, such as lighting loads defining zones, has a zone select switch for scrolling through multiple zones, so as to permit a single control unit (having a power level adjustment switch and a power level display for one zone) in the control panel to be used to separately adjust the power level for, and separately display the power level of, more than one zone. The control panel is capable of controlling M times N zones, where N is the number of control units in the control panel, and where M represents the number of selections that can be made by the zone select switch.
