<p>A system and process for controlling power delivered to an electrical load to controllably effect operation of the load (e.g., intensity of illumination). In at least some embodiments, the system and process interpret a user-adjustable setting of a typical electronic low voltage (ELV) dimmer control device that is otherwise isolated from facility AC power. An electrical stimulus, such as a relatively low power AC or DC voltage, is applied at one or more externally accessible terminals of the ELV dimmer control. An electrical response of the dimmer control to the stimulus is measured at one or more externally accessible terminals of the dimmer control. The electrical response varies according to the applied electrical stimulus and a user-adjustable setting of the dimmer control. An indication of the setting of the user-adjustable control is determined from the measured electrical response, and used to correspondingly dim a lighting source.</p> |
