Abstract: A system for distributed device management includes a group of devices. Each device in the group of devices communicate with one or more other devices in the group of devices over one or more network channels, and each device in the group of devices includes a processing circuit. The processing circuit of each device in the group of devices manages one or more devices in the group of devices, authorizes a new device to join the group of devices, and synchronizes data with the new device and with one or more devices in the group of devices over the one or more network channels.

Abstract: A heat exchanger includes a frame and a plurality of coil passes disposed within the frame. The plurality of coil passes is configured to direct a flow of a refrigerant therethrough to transfer heat with an air flow passing over the heat exchanger. The plurality of coil passes include a U-bend disposed between first and second linear portions of the plurality of coil passes to redirect the refrigerant from a first longitudinal end of the heat exchanger to a second longitudinal end of the heat exchanger. Additionally, a first plurality of fins is disposed on an outer surface the U-bend.

Abstract: A thermostat is disclosed. The thermostat can include one or more temperature sensors configured to measure one or more temperature values. The thermostat can include a processing circuit. The processing circuit can receive the one or more temperature values from the one or more temperature sensors. The processing circuit can receive one or more central processing unit (CPU) usage values, wherein the one or more CPU usage values indicate computing usage of the processing circuit. The processing circuit can determine, based on an empirical model comprising one or more gain values and one or more filters and based on one or more signals, a temperature of the building. The one or more signals comprise the one or more temperature values and the one or more CPU usage values. The empirical model accounts for dynamics of heat generated by the processing circuit and airflow acting on the thermostat.

Abstract: The present disclosure relates to a gas valve assembly for a furnace. The gas valve assembly includes a gas valve including an inlet flange having an outer geometric profile and defining a gas inlet of the gas valve. The gas valve assembly also includes a bracket having a mounting panel, a first support flange, and a second support flange, where the mounting panel extends between and is integral with the first support flange and the second support flange. A slot is formed in the first support flange and defined by a portion of a perimeter of the bracket. The outer geometric profile of the inlet flange corresponds to a profile of the slot, and the slot is configured to receive and abut a portion of the outer geometric profile. A passage is formed in the second support flange and configured to receive a gas flow from the gas valve.
