The present disclosure relates to a heating, ventilation, and/or air conditioning (HVAC) system that includes a controller configured to receive a call for conditioning from each zone of a plurality of zones, where each zone of the plurality of zones includes a damper. The controller is also configured to determine a priority level of each zone of the plurality of zones and to control operation of the HVAC system to sequentially open the dampers of the plurality of zones based on the priority levels of the plurality of zones.

Damper control systems and methods for a zoning system

A zoning system for a heating, ventilation, and/or air conditioning (HVAC) system includes a temperature control device configured to monitor a temperature in a zone of a structure for conditioning by the HVAC system and configured to send a wireless control signal including data based on the temperature, and a damper actuator configured to be associated with the zone and configured to adjust a position of a damper to control an airflow into the zone, where the damper actuator is configured to receive the wireless control signal from the temperature control device and configured to adjust the position of the damper based on the data.

Integrated zone control system

A heating, ventilation, and/or air conditioning (HVAC) system includes a set of electrical switches and a controller configured to determine a calibration value of an operating parameter of the HVAC system based on a plurality of configurations of the set of electrical switches during operation of the HVAC system in a calibration mode, receive a measured value of the operating parameter from a sensor of the HVAC system during the operation of the HVAC system in the calibration mode, and determine a parameter value adjustment for the measured value based on a comparison of the measured value and the calibration value.

Systems and methods for operating an HVAC system in a calibration mode

The present disclosure includes systems and methods for determining dimensions, shapes, and locations of rooms of a building using a mobile device for controlling heating, ventilation, and air conditioning (HVAC) provided to the rooms and building. A measuring device receives a shape of a room in the building and determines a dimension set of the room based on the shape of the room. The measuring device transmits the shape of the room and the dimension set to a mobile device that determines a layout of the building based on the shapes and the dimension sets corresponding to the rooms of the building. In this manner, the systems and methods provide the layout of the building more efficiently, resulting in an improved HVAC system installation and operation process.

Mobile device building layout determination systems and methods

The present disclosure includes an HVAC system that includes a plurality of dampers each corresponding to one building zone of a plurality of building zones, a plurality of sensors each corresponding to the one of the plurality of building zones, and a control board communicatively coupled with the plurality of dampers and sensors. The control board includes a plurality of status light sources, each corresponding to one damper the plurality of dampers, a plurality of communication light sources each corresponding to one sensor of the plurality of sensors, and a microcontroller programmed to control operation of equipment in the HVAC system. The microcontroller is configured to perform 'a hardware test mode' to facilitate diagnosis of the plurality of dampers by causing the plurality of status light sources to sequentially execute a first light scheme or a second light scheme in response to instructions to the plurality of dampers.

Control board systems and methods for diagnosis of HVAC components

Embodiments of the present disclosure are directed to a controller for a heating, ventilation, and/or air conditioning (HVAC) system. The controller is configured to operate in a first defrost mode or a second defrost mode, determine that feedback from a first sensor of the HVAC system is unavailable, receive feedback from a second sensor of the HVAC system, and operate the HVAC system in the second defrost mode instead of the first defrost mode in response to unavailability of the feedback from the first sensor and based on the feedback from the second sensor.

Alternative defrost mode of HVAC system

An outdoor unit for a building HVAC system includes one or more sensors configured to measure temperature and pressure values. The unit also includes a user interface coupled to the outdoor unit. The user interface is configured to display information to a user. The unit includes a controller including a processing circuit. The processing circuit configured to record the temperature values and the pressure values via the sensors and cause the user interface to display temperature values and pressure values.

Building equipment with interactive outdoor display

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.

HVAC switchable communication bus and power bus control board systems and methods

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.

Alternative feedback usage for HVAC system

A controller for a heating, ventilation, and/or air conditioning (HVAC) system is configured to detect an input voltage received as a power supply by the HVAC system, determine the input voltage exceeds a threshold value, and identify a voltage variation event based on determining that the input voltage exceeds the threshold value.

A heating, ventilation, and air conditioning (HVAC) system includes a controller associated with a residence. The controller is configured to determine an expected value range for an operating parameter of a component of the HVAC system. Additionally, the controller is configured to receive a signal from a sensor indicative of a current value of the operating parameter of the component and determine if the current value of the operating parameter is outside the expected value range. Based on the determination that the current value is outside the expected value range, the controller is additionally configured to initiate a diagnostic mode of the controller. In the diagnostic mode, the controller is configured to collect diagnostic data associated with the HVAC system.
