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 system includes a two stage heat exchanger and a processor. The processor is configured to receive a call from a thermostat and execute, in response to the call, an adaptive staging algorithm. The adaptive staging algorithm is configured to determine, in response to a recent cycle of the two stage heat exchanger being a first stage cycle, a first stage up time of the two stage heat exchanger as a first function of a first value, the first value corresponding to the recent cycle being the first stage cycle. The adaptive staging algorithm is also configured to determine, in response to the recent cycle of the two stage heat exchanger being a second stage cycle, a second stage up time of the two stage heat exchanger as a second function of a second value, the second value corresponding to the recent cycle being the second stage cycle, where the first and second values are different.

Abstract: The present disclosure relates to a zoning system for climate control including a controller configured to operate the zoning system to supply conditioned air to a first zone of a plurality of zones through a first supply air damper to thermally charge the first zone. The controller is also configured to close the first supply air damper of the first zone and open a second supply air damper of a second zone of the plurality of zones after the first zone is thermally charged. The controller is further configured to operate the zoning system to draw the conditioned air from the first zone and supply the conditioned air to the second zone through the second supply air damper.

Abstract: The present disclosure includes a heating, ventilation, and air conditioning (HVAC) system having a control system suitable to control operation of a device in the HVAC system. The control system may include a zone control panel that may control operation of the device using power-line communication. Accordingly, the zone control panel and the device may be both communicatively and electrically coupled via one or more power lines. To that end, the zone control panel may determine a primary address identifying the device and/or a secondary address indicating the one or more power lines electrically coupled to the device. Further, the zone control panel may communicate with and/or coordinate operation of the device by transmitting data messages to the device via the one or more power lines based on the primary address and/or the secondary address.

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 control system for a heating, ventilation, and/or air conditioning (HVAC) system includes a controller. The controller is configured to control the HVAC system to condition an air flow based on first feedback from a first sensor of the HVAC system, receive second feedback from a second sensor of the HVAC system, and control the HVAC system to condition the air flow based on the second feedback instead of the first feedback when the first feedback from the first sensor being no longer available. The first feedback is indicative of a first operating parameter of the HVAC system, and the second feedback is indicative of a second operating parameter of a refrigerant flowing through the HVAC system.

Abstract: The techniques described herein provide systems and methods for guiding a user to accurately measure the volume of each room in a zoned HVAC system using a mobile device. An application on the mobile device guides the user in taking photographs of each room from various positions, various angles, or both. After the mobile device has acquired the photographs, stereophotogrammetry may be used with the acquired photographs to determine the volume of each room. A control system may then calculate an appropriate airflow to be provided to each room based on the volume of each room.
