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, a stepper motor, and a pointer connected to the stepper motor. Additionally, the device includes processing circuitry configured to control the stepper motor in order to cause the pointer to indicate a first marker of the set of markers, wherein the first marker corresponds to a current parameter value and control a dial to indicate a set point parameter value by indicating a second marker of the set of markers which corresponds to the set point parameter value.

A power stealing system having an electrical load, a capacitive element having an input connected to the electrical load. Some power from the electrical load may go through the capacitive element to an input of a rectifier. A voltage regulator may have an input connected to an output of the rectifier to set and control a voltage level of the electrical power from the rectifier, and provide an output of power stolen from the electrical load. An amount of power flowing through the capacitive element may be less than one percent of power flowing through the electrical load.
