摘要： A system for detecting a control loop interaction between two or more control loops. The system includes a processing circuit configured to store a history of detected loop disturbances for a plurality of control loops. The processing circuit is also configured to compute a measure of interaction between control loops using the history of detected loop disturbances. The processing circuit is further configured to determine whether a loop interaction exists based on the computed measure of interaction.

摘要： A system is disclosed for detecting faults in an environmental control system for a building zone. The system includes a circuit configured to determine that a fault exists based on a comparison of the current value for the climate condition in a heating state and the estimate of the climate condition at which a transmission from the heating state to the no heating state is expected to be caused by a finite state machine of the system.

摘要： A system is disclosed for detecting faults in an environmental control system for a building zone. The environmental control system is controlled by a finite state machine that causes states of the environmental control system to change based on a varying climate condition. A circuit is configured to receive a current value for the climate condition when the environmental control system is in a heating state and to calculate an estimate of the climate condition at which a transition from the heating state to a state of no heating by the environmental control system is expected to be caused by the finite state machine. The circuit is configured to determine that a fault exists based on a comparison of the current value for the climate condition in the heating state and the estimate of the climate condition at which a transition from the heating state to the no heating state is expected to be caused by the finite state machine.
