Abstract: 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.

Abstract: A non-transitory computer-readable storage medium for a heating, ventilation, and/or air conditioning (HVAC) system includes instructions that, when executed by a processor, cause the processor to receive an input indicative of a user location, perform a verification that the user location is within a determined distance from the HVAC system, and control access to system settings of the HVAC system based on the verification.

Abstract: A control system for a heating, ventilation, and/or air conditioning (HVAC) system includes control circuitry having a storage device and a microcontroller. The storage device is configured to store faults. The microcontroller is configured to monitor for a condition of the HVAC system associated with a fault, store a fault in the storage device when the condition is detected, identify whether a duration of time that the fault has been stored in the storage device exceeds a threshold time period, and clear the fault from the storage device when the duration exceeds the threshold time period.

Abstract: The present disclosure includes systems and methods for pre-programming a thermostat such that operational parameters of the thermostat may be selected by an installer during installation based at least in part on a location of the thermostat. For example, a thermostat communicatively coupled to conditioned air equipment may include location determination logic configured to determine a location of the thermostat with respect to a building for which the conditioned air equipment operates. The thermostat also includes conditioned air equipment control logic comprising a plurality of sets of static location-based temperature control algorithms. Each set of the static location-based temperature control algorithms corresponds to a location of the thermostat with respect to the building. The conditioned air equipment control logic is configured to control operation of the conditioned air equipment using a set of the static location-based temperature control algorithms that corresponds to the location determined by the location determination logic.

Abstract: The present disclosure includes techniques that enable a conditioned air system to automatically restore functionality and/or to operate at reduced functionality when a fault is detected, for example, to facilitate reducing likelihood that continuing operation with the fault present will decrease lifespan of the conditioned air system. To facilitate improving operation of the conditioned air system when a fault is present, the control system of the conditioned air system may utilize substitute sensor data and/or adjust its control algorithm. In this manner, the control system may facilitate improving operational reliability and/or availability of the conditioned air system, for example, by adaptively adjusting its operation to enable the conditioned air system to continue operating even when a fault is present, while reducing likelihood that the continued operation will reduce lifespan of the conditioned air system.

Abstract: A residential HVAC system includes, a compressor, and an outdoor unit controller in communication with the compressor. The outdoor unit controller is configured to receive an indoor ambient temperature and a temperature set point. The outdoor unit controller is further configured to determine an outdoor ambient temperature, and to determine an operating value for the compressor based on a percentage of a delta between a minimum operating value of the compressor and a maximum operating value of the compressor, plus the minimum operating value. The minimum operating value and the maximum operating value are based on the determined outdoor ambient temperature. The percentage of the delta is based on a predefined temperature differential multiplier and one or more time dependent multipliers. The outdoor unit controller is further configured to modify the current operating value of the compressor with the determined operating value.

Abstract: The present disclosure includes a control board including a switchable input/output port. The switchable I/O port may provide a switchable communication bus capable of selectively supporting one of multiple different communication protocols and may provide a switchable power bus capable of selectively conducting electrical power from one of multiple different power supplies. As such, the control board may communicatively and/or electrically couple to a wide range of devices. To that end, the control board may support the dynamic interchange and reconfiguration of devices coupled to the control board, allowing a control system including the control board greater operational flexibility.

Abstract: Systems and methods to control an electronic expansion valve (EEV) of a vapor compression system are described. A heating ventilation, and air conditioning (HVAC) system includes control circuitry having a sensor. The control circuitry sets a control setpoint of a vapor compression system such that an electronic expansion valve operates across a first operating range. The control circuitry receives a signal from the sensor indicative of an operating condition of the vapor compression system. The control circuitry adjusts the control setpoint based at least in part on the operating condition. The control circuitry controls operation of the electronic expansion valve based at least in part on the adjusted control setpoint, wherein the electronic expansion valve operates across a second operating range, different from the first operating range, at the adjusted control setpoint.
