Abstract: A building system includes heating ventilation or air conditioning (HVAC) devices configured for communication on a building automation network and a communication engine. The communication engine is configured to provide a diagnostic attribute. The diagnostic attribute indicates communications with the HVAC devices as being according to a first communication protocol or at least one different communication protocol. Systems and methods may detect insecure communications and/or upgrade in secure communication protocols in wireless or wired networks, such as, BACnet systems and/or subsystems

Abstract: A variable air volume controller includes a communications interface and a processing circuit. The communications interface is configured to facilitate communication with an external device and building equipment. The processing circuit is configured to store a plurality of predefined, selectable-applications; receive a selection of one of the plurality of predefined, selectable-applications; and implement the selected application such that the building equipment is controlled according to the selected application.

Abstract: An equipment controller in a building management system (BMS) includes a feature detector and a dynamic point list generator. The feature detector is configured to receive sensor input from a sensor and determine a set of features available to the equipment controller based on the sensor input. The dynamic point list generator is configured to determine unavailable features based on the set of available features and identify one or more points in a complete point list associated with the set of unavailable features. The dynamic point list generator is configured to generate a dynamic point list by removing the identified points from the complete point list and expose the dynamic point list to a BMS controller communicably connected to the equipment controller.

Abstract: A heating, ventilation, or air conditioning (HVAC) system with automated flow direction detection is provided. The HVAC system includes one or more hoses configured to provide airflow from HVAC equipment, a bidirectional pressure sensor coupled to the hoses, and a controller coupled to the bidirectional pressure sensor. The controller is configured to receive a signal from the bidirectional pressure sensor, determine a direction of the airflow relative to the bidirectional pressure sensor based on the signal, correct the signal for a reversed hose polarity relative to the bidirectional sensor based on the direction of the airflow, and perform a control activity using the corrected signal.
