1. An electrical wiring device comprising:
- a housing assembly including a plurality of terminals at least partially disposed therein, the plurality of terminals being configured to be coupled to an AC power source and at least one electrical load, the plurality of terminals being configured to provide the at least one electrical load with regulated AC power in a device energized state;
at least one variable control mechanism coupled to the housing assembly, the at least one variable control mechanism including a control knob being user settable between a first adjustment stop and a second adjustment stop;
a user accessible calibration button;
at least one series pass element coupled to the at least one variable control mechanism, the at least one series pass element being configured to regulate load power to the at least one electrical load in accordance with a user setting of the control knob,wherein the series pass element is configured to regulate the load power from a minimum load power when the control knob is at or near the first adjustment stop to a first maximum load power when the control knob is at or near the second adjustment stop; and
a regulation circuit coupled to the user accessible calibration button and the at least one series pass element, the regulation circuit being configured to enter a calibration mode when the control knob is at or near the second adjustment stop and the user manually actuates the calibration button, the regulation circuit associating the second adjustment stop with at least one pre-determined second maximum load power when the calibration button is actuated and when the regulation circuit is in the calibration mode,wherein the second maximum load power is different from the first maximum load power.

Abstract
The present invention is directed to an electrical wiring device that includes a variable control mechanism configured to regulate power to the at least one electrical load by way of a control knob being user settable between a first adjustment stop and a second adjustment stop. A regulation circuit is configured to establish a pre-determined load power setting when the calibration button is actuated when the regulation circuit is in the calibration mode.
