Patent ID: 8598978

Claim:
A method of assigning a radio frequency transmit-only remote control device to a radio frequency load control system, the load control system comprising a plurality of two-way control devices that transmit and receive RF control signals to control the operation of electrical loads, the method comprising: transmitting a plurality of enter address mode commands to the two-way control devices; pausing the transmission of the enter address mode commands for a predetermined period of time before repeating the transmission of the enter address mode commands; entering the transmit-only remote control device into an activation mode; transmitting from the transmit-only remote control device an activation request message that includes a unique identifier of the transmit-only remote control device; at a receiving control device of the load control system, receiving the activation request message from the transmit-only remote control device during the step of pausing the transmission of the enter address mode commands; and if the activation request message has been received, checking a memory of the receiving device to determine if the unique identifier is already stored, and, if not already stored, storing the unique identifier in the memory to assign the transmit-only remote control device to the load control system; wherein the transmit-only remote control device, when in the activation mode, transmits a plurality of activation request messages wherein the plurality of activation request messages are transmitted for a length of time that exceeds a length of time that the plurality of enter address mode commands are transmitted so that an activation request message will be present during at least part of the pause so that the receiving device can receive the activation request message during the pause.
