Abstract:
A thermostat for a building includes a communications interface communicably coupled to an HVAC network and a processing circuit. The processing circuit is configure to determine that a HVAC device is connected to the HVAC network and retrieve a software update from the HVAC device via the communications interface and install the software update in response to a determination that the thermostat must install the software update in order to be configured to communicate with the HVAC device.

Abstract:
In one embodiment of the present disclosure, a heating, ventilating, and air conditioning (HVAC) system includes a refrigerant circuit configured to flow a refrigerant. The refrigerant circuit includes a compressor configured to compress the refrigerant, a condenser configured to receive the refrigerant from the compressor and to condense the refrigerant, a valve configured to receive a first portion of the refrigerant from the condenser and to decrease a pressure of the first portion of the refrigerant, and an evaporator configured to receive the first portion of the refrigerant from the condenser and configured to evaporate the first portion of the refrigerant. The refrigerant circuit also includes a refrigerant sub-circuit configured to receive a second portion of the refrigerant from the condenser and to convert thermal energy of the second portion of the refrigerant to electrical energy.
Abstract:
A thermostat for a building space includes a network communication module and a processing circuit. The network communication module is communicatively coupled to at least one of one or more social media servers and one or more calendar servers. The processing circuit is configured to receive at least one of social media activity, social media events, and calendar events associated with a user via the network communication module. The processing circuit is further configured to determine an expected occupancy of the building based on at least one of the social media events and the calendar events. The processing circuit is further configured to adjust a setpoint of the thermostat based on at least one of the expected occupancy and the social media activity.
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:
A heating, ventilating, and air conditioning (HVAC) includes a processor and a plurality of sensors. The plurality of sensors can collect a first set of data indicative of environmental conditions of a structure in which the HVAC control device is located. The HVAC control device can control operational settings of an HVAC system that can supply conditioned air to the structure and operate the HVAC system in a default mode. The HVAC control device can also receive a second set of data collected by one or more sensors of a secondary input device and receive a signal from the secondary input device. Additionally, the HVAC control device can implement an override mode of the control device based on the signal. Implementation of the override mode effectuates a change in the operational settings of the HVAC system.
Abstract:
A heating, ventilation, and/or air conditioning (HVAC) system includes processing circuitry configured to receive a plurality of air flow rates, in which each air flow rate of the plurality of air flow rates is associated with a zone of a plurality of zones of the HVAC system, determine a sum of the plurality of air flow rates is outside of a threshold range around a total output air flow rate, and, in response to determining the sum of the plurality of air flow rates is outside of the threshold range around the total output air flow rate, adjust an air flow rate of the plurality of air flow rates based on a comparison between the sum of the plurality of air flow rates and the total output air flow rate.
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 techniques described herein provide systems and methods for controlling climate characteristics in a building. The control system of a climate management system may calculate a default airflow rate for each zone in the building based on a minimum permitted airflow rate of climate control equipment, a maximum permitted airflow rate of the climate control equipment, and the number of zones serviced by the climate control equipment. The control system may also adjust the default airflow rate for a zone to a customized airflow rate based on a user input. The control system may adjust the default airflow rate to the customized airflow rate if the customized airflow rate is greater than or equal to the minimum permitted airflow rate. The control system may adjust the default airflow rate to the minimum permitted airflow rate if the customized airflow rate is less than the minimum permitted airflow rate.
