1. A method of controlling an operation of an electrical device within an electrical system, the method comprising the steps of:
receiving, at a line controller of the electrical system, a user-selected mode of operation for the electrical device;
wherein the user-selected mode of operation includes two dimensions associated with the user-selected mode of operation;
generating a command message corresponding to the user-selected mode of operation by operating a switching device of the line controller to selectively interrupt power to the electrical device, wherein the command message encodes the user-selected mode of operation in accordance with a multi-field command protocol comprising:
a first variable length OFF time;
a variable length ON time following the first variable length OFF time; and
a second variable length OFF time following the variable length ON time, wherein the first OFF time, the ON time and the second OFF time form three discrete fields of the command message, with each field having a value represented by its length, wherein at least one of the three fields, or the three fields together, define a command to control the electrical device in accordance with the user-selected mode of operation, and wherein the at least one of the three fields defines a parameter to control the electrical device in accordance with at least one of the two associated dimensions; and
wherein the three fields of the command message together define the command and two parameters to control the electrical device in accordance with the user-selected mode of operation and the two associated dimensions,
receiving, at the electrical device of the electrical system, the command message; and
operating the electrical device in accordance with the user-selected mode of operation and the two associated dimensions.
