Abstract: A building management system (BMS) operates a plurality of HVAC devices to affect a physical state or condition and detects a fault condition at a second HVAC device affected by the physical state or condition and having causal relationships with the plurality of HVAC devices such that faulty operation of one or more of the plurality of HVAC devices causes a detectable effect at the second HVAC device. The BMS identifies, based on the fault condition, a predetermined set of system parameters corresponding to the fault condition and comprising a plurality of system parameters of the plurality of HVAC devices that are potential causes of the fault condition. The BMS retrieves operating data for the predetermined set of system parameters and transmits a signal to display a user interface comprising the operating data on a display screen.

Abstract: A system for controlling a flow rate of a fluid through a valve includes a controller. The controller is configured to receive a raw flow rate measurement from a flow rate sensor assembly configured to measure the flow rate. The controller is further configured to apply a flow rate measurement filter to the raw flow rate measurement to generate a filtered flow rate measurement. The controller is further configured to control actuation of an actuator configured to change the flow rate using the filtered flow rate measurement. The controller is configured to automatically adjust the flow rate measurement filter in response to detecting an event that causes stoppage of the actuation of the actuator.

Abstract: A system for controlling building equipment devices includes a processing circuit comprising a processor and memory storing instructions executed by the processor. The system is configured to generate a first combination profile indicating a number of active devices within each of one or more device groups according to a first combination of the building equipment devices, and generate a second combination profile indicating a number of active devices within each of the one or more device groups according to a second combination of the building equipment devices. The system is also configured to compare the first combination profile against the second combination profile to determine whether the first combination is redundant with the second combination, generate control decisions for the building equipment devices based on whether the first combination is redundant with the second combination, and operate the building equipment devices in accordance with the control decisions.
