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 control system has an air conditioner that communicates with a file server via a network. The file server includes a lifestyle log in which information associating lifestyle information indicating a lifestyle with a control method of the air conditioner is accumulated. A first control-operation functional unit operates the air conditioner based on a first control request acquired from a first device. A second control-operation functional unit selects a control method from the lifestyle log based on a second control request acquired from a second device with higher functionality than the first device, and operates the air conditioner using the selected control method.

The present disclosure presents techniques for improving operational efficiency of climate control systems. A climate control system may include climate control equipment, a sensor that measures temperature in a building, and a control system that controls operation of the equipment using a first temperature schedule, which associates each time step with a temperature setpoint, when the building is occupied. When not occupied, the control system determines an expected return time based on historical occupancy data associated with the building, determines the temperature setpoint associated with the expected return time, determines candidate schedules each expected to result in the inside air temperature meeting the temperature setpoint, determines efficiency metrics each associated with one of the candidates based on historical performance data resulting from previous operation of the climate control system, and controls operation of the equipment based on a second temperature schedule selected from the candidates based on associated efficiency metrics.
