Patent ID: 7999485

Claim:
A power control wiring device comprising: at least one terminal configured to be connected to a source of AC power; an electronic switch circuit coupled to at least one electrical load, the electronic switch circuit providing a switch actuation signal selectively energizing the electrical load during a portion of an AC cycle in accordance with a timing regulation signal; a timing regulation circuit coupled to the at least one terminal and the electronic switch circuit, the timing regulation circuit being configured to generate the timing regulation signal, the timing regulation circuit including a primary timing regulation circuit adjustable between a minimum power setting and a maximum power setting to thereby generate an adjustable primary timing regulation signal, the timing regulation circuit including an auxiliary timing regulation circuit configured to generate an auxiliary timing regulation signal that trims the maximum power setting in accordance with a selectable trim adjustment to thereby reduce power consumption relative to the maximum power setting, the timing regulation signal being a combination of the primary timing regulation signal and the auxiliary timing regulation signal; a primary manual power control mechanism configured to adjust the primary timing regulation circuit between the minimum power setting and the maximum power setting; and at least one auxiliary manual power control mechanism configured to trim the maximum power setting in accordance with the selectable trim adjustment, the at least one auxiliary manual power control mechanism being user accessible.
