Method of automatically programming a load control device using a remote identification tag

摘要

A method of automatically programming a new load control device that replaces an old load control device takes advantage of a remote identification tag (e.g., an RFID tag) located in the vicinity of the old device. The remote identification tag stores an identifier that is representative of a location in which the old device is installed. The method includes the steps of: (1) storing a setting of an old device in a memory of a controller; (2) associating the setting with the identifier of the old device in the memory of the controller; (3) the new device retrieving the identifier from the remote identification tag after the new device is installed in the location of the old device; (4) the new device transmitting the identifier to the controller; and (5) the controller transmitting the setting of the old device to the new device in response to receiving the identifier.

主权项

1. A load control device for controlling the power delivered from an AC power source to an electrical load, the load control device comprising:
a load control circuit adapted to be coupled between the AC power source and the electrical load; a controller operatively coupled to the load control circuit for controlling the power delivered to the electrical load; a first communication circuit operatively coupled to the controller and adapted to be coupled to a communication link, such that the controller is operable to transmit and receive digital messages via the communication link; and an identifier retrieval circuit comprising a second communication circuit coupled to the controller, the identifier retrieval circuit operable to transmit a digital message to a remote identification tag located in the vicinity of the load control device, and to receive a digital message including an identifier from the remote identification tag; wherein the load control device is adapted to be mounted adjacent to or in a fixture in which the remote identification tag is located, the identifier of the remote identification tag representative of a location of the fixture, the controller operable to transmit a digital message including the identifier on the communication link via the first communication circuit, and to subsequently receive a digital message including a load control setting associated with the identifier via the first communication circuit.
