A load control device for controlling the amount of power delivered from an AC power source to an electrical load comprises a rotary actuator, such as a rotary knob or a rotary wheel. The load control device increases and decreases the amount of power delivered to the electrical load in response to rotations of the rotary knob in first and second directions, respectively. The load control device accelerates the rate of change of the amount of power delivered to the load in response to the angular velocity of the rotary actuator. The load control device generates a ratcheting sound when the rotary actuator is rotated in the first direction at a high-end intensity of the load control device. The load control device is operable to control the electrical load in response to both actuations of the rotary actuator and digital messages received via a communication link.
