Abstract
In some examples, a device controls a heating, ventilation, and air conditioning (HVAC) system within a building. The device includes an analog display including a set of markers. Additionally, the devices includes processing circuitry configured to determine whether one or both of a cooling set point mode and a heating set point mode is activated and cause a set point to change from a first set point value to a second set point value in response to receiving a first rotation input to a dial. Additionally, the processing circuitry is configured to control a set of LEDs to transition from illuminating a first marker of the set of markers to illuminating a second marker of the set of markers, wherein the first marker corresponds to the first set point value and the second marker corresponds to the second set point value.
