Abstract
An energy control system (10) comprises at least one controllable load (110), a master controller (200), a traveler wire (300) and at least one remote switch (400). The master controller (200) transmits control commands that effect corresponding control actions in the controllable load (110). The remote switch (400) transmits remote commands to the master controller (200) over the traveler wire (300). The energy control system (10) is well suited for installation in standard three-way switch or four-way switch electrical systems and requires neither additional wiring nor complicated installation procedures.
