Abstract
A device having indirect visual indicators to communicate information about states of operation is disclosed herein. The visual indicators may output a visual indication based on operational states of the device or other systems associated with the device. In some examples, a thermostat may include a downcast light that outputs a visual indication based on a mode of operation of the thermostat or a mode of operation of an associated heating, cooling, and ventilation (HVAC) system. Various characteristics of the visual indication may be altered to output different information. In some examples, a color of the visual indication may change based on the modes of operation or the visual indication may be pulsed based on the modes of operation.
