The Synergy~174; Controllable Breaker Panel Networked (MLX) system controller adds programming, automation and networking capabilities to a Synergy system. Capabilities include individual circuit switching control of lighting functions for a wide variety of applications. System outputs respond to time-of-day schedules via the internal time clock. Additionally, inputs can be accepted from external devices such as simple switches, photocells, occupancy sensors, telephones and other control systems to directly control lighting or override scheduled events. Over 4,000,000 Synergy MLX controllers may be interconnected to provide access to more than 500,000,000 control outputs from a single switch or schedule.
