A room controller manages lighting fixtures and controlled receptacles fed by separate electrical panels. Power is supplied from a 20-amp single-pole 277-volt H panel for lighting and a 20-amp single-pole 120-volt L panel for receptacle circuits. Occupancy sensors connect to the room controller to automate switching functions in large rooms.
