A refrigerating appliance includes a refrigerating compartment enclosed by a housing and by a door. When first entering the selective temperature imaging mode of operation, the system and method automatically determine the hottest area in a scene and display it in a predetermined hue. Yet further embodiments include both data collection and analytic discovery. In addition, the electrical connector includes a first deflector configured to be coupled to the first power cable and control an alternating current electric field generated in the first cable termination chamber. The connector provides enhanced heat dissipation characteristics and is particularly useful for high current applications such as for connecting batteries, accumulators, super-capacitors and the like storage power units for electric vehicle and other applications. In training the user, the device processes test image’s information located within the device’s field of view.
