A distributed intelligence lighting system is comprised of a global controller, one or more local controllers, wall stations, sensors and lighting fixtures. In one aspect, the lighting system provides schedule-based, occupancy-based, and/or daylight-responsive automated control and multi-level or ON/OFF manual control of lighting loads. System components communicate over a topology-free and polarity-free modular low voltage digital network that combines power and control wiring in an easily installed labeled and keyed cable. Embodiments according to the system do not require any components to be addressed, manually configured, or programmed (beyond setting the project location and current time and date) for energy code compliance. Manual and after-hours override control is accomplished via local low voltage wall stations or occupancy sensors. Global controllers generally each incorporate an onboard modem and user interface with LCD display, both permitting programming of advanced features, override, system monitoring, and diagnostics.
