    Abstract: Systems and methods of generating performance index for connected equipment in a building management system are provided. The connected equipment measures monitored variables and generates status codes. The system obtains data points of the monitored variables and the status codes from past N time units, and connected equipment specific parameters. The system performs first performance checks for the connected equipment using the status codes from the past N time units. The system performs second performance checks using the data points of the monitored variables from the past N time units, the connected equipment specific parameters, and a set of predetermined rules. The system determines individual performance check indicators based on the first performance checks and the second performance checks using first weights each determined based on a different timing. The system generates an overall performance index for the connected equipment using the individual performance check indicators and second weights.

    Abstract: A building management system includes a communications bus, field devices connected to the communications bus, a cloud service including a machine learning engine; and a controller for an HVAC device. The controller communicates with the communications bus and the cloud service and is configured to transmit messages through the communications bus to the field devices, compile a list of connected field devices, receive sample data from the connected field devices, and transmit the sample data from the connected field devices to the cloud service. The controller is further configured to receive identifying characteristics for each of the connected field devices from the cloud service and to select a control logic file for the HVAC device based on the identifying characteristics.

    Abstract: A multi-tiered data storage system for building management system (BMS) data includes a plurality of data stores including a first data store and a second data store. The system further includes a data access router configured to provide a consistent endpoint for the BMS data to an application that provides or consumes the BMS data regardless of whether the BMS data is stored in the second data store or the first data store, obtain a requested data object of the BMS data from the second data store in response to a determination that the requested data object is available in the second data store, and obtain the requested data object from the first data store in response to a determination that the requested data object is not available in the second data store.

    Abstract: A heating, ventilation, and/or air conditioning (HVAC) unit includes a drain pan including a basin defined by a base and a plurality of side walls configured to collect condensate from an evaporator of the HVAC unit. The HVAC unit also includes a drain port disposed in the base of the basin and arranged such that the drain pan is configured to direct the condensate toward the drain port and out of the basin, a protruded portion extending from an outer surface of a side wall of the plurality of side walls, and a passage proximate to a top edge of the side wall of the plurality of side walls and configured to facilitate overflow of the condensate out of the basin and along the protruded portion.

    Abstract: A control system includes a device of building equipment operable to alter a variable state or condition of a building in response to a command, a controller in communication with the device and operable to generate the command by executing an expected control sequence in response to one or more inputs, and a system manager. The system manager is configured to automatically verify that the controller executes the expected control sequence by automatically generating test logic based on a common data model tag for the device. The test logic specifies an input condition and an expected system response. The system manager is further configured to automatically verify that the controller executes the expected control sequence by adjusting one or more of the one or more inputs such that the input condition is satisfied and determining whether the expected system response occurs.
