Abstract
A refrigerator is provided having at least one internal refrigerated compartment in which a plurality of refrigeration zones are provided, wherein an environment in each refrigeration zone may be independently controlled using a user interface configured to receive a zone selection input from a user indicating one of the plurality of refrigeration zones in which the user desires to adjust the environment; a plurality of lights provided in the internal refrigerated compartment and disposed proximate to each of the plurality of refrigeration zones, wherein groups of the plurality of lights may be separately controlled for visually identifying each of the refrigeration zones; and a controller configured to receive a zone selection input from the user interface, identify a group of the plurality of lights that are disposed proximate the selected refrigeration zone, and control the identified group of the plurality of lights to visually confirm the selected refrigeration zone.
