Abstract:
1. A system for controlling the intensity of a lighting load powered from an AC power source, the load control device comprising: a controllably conductive device adapted to be coupled in series electrical connection between the AC power source and the lighting load; a controller coupled to a control input of the controllably conductive device, the controller operable to control the controllably conductive device to adjust the intensity of the lighting load; a communication circuit operable to receive digital messages on a communication link, the controller coupled to the communication circuit, such that the controller is operable to adjust the intensity of the lighting load in response to the received digital messages; and a rotary actuator operable to rotate in a first direction and a second direction, the digital messages transmitted to the communication circuit in response to actuations of the rotary actuator, such that the controller is responsive to rotations of the rotary actuator to increase the intensity of the lighting load when the rotary actuator is rotated in the first direction and to decrease the intensity of the lighting load when the rotary actuator is rotated in the second direction; wherein the rotary actuator is continuously rotatable, such that the position of the rotary actuator is not representative of the intensity of the lighting load.
