A load
control system for controlling the amount of power delivered from an
AC power source to a plurality of
electrical load includes a plurality of independent units responsive to a broadcast controller. Each independent unit includes at least one commander and at least one energy controller for controlling at least one of the electrical loads in response to a
control signal received from the commander. The independent units are configured and operate independent of each other. The broadcast controller transmits
wireless signals to the energy controllers of the independent units. The energy controllers do not respond to control signals received from the commanders of other independent units, but the energy controllers of both independent units respond to the
wireless signals transmitted by broadcast controller. The energy controller may operate in different operating
modes in response to the
wireless signals transmitted by the broadcast controller.
