Abstract: A HVAC controller located within a building zone includes a housing, a wireless radio, a controller monitor, a temperature sensor, and a temperature compensation module. The wireless radio is contained within the housing and is configured to transmit data via a wireless HVAC network. The controller monitor is configured to detect wireless activity of the wireless radio, the wireless activity generating heat inside the housing and causing a temperature inside the housing to exceed a temperature of the building zone outside the housing. The temperature sensor is configured to measure the temperature inside the housing. The temperature compensation module is configured to determine a wireless heat rise resulting from the wireless activity, to calculate a temperature offset based on the wireless heat rise, and to determine the temperature of the building zone outside the housing by subtracting the temperature offset from the temperature measured inside the housing.

Abstract: A plant includes equipment that operate to affect a variable state or condition of the plant in response to a control signal. A feedback controller monitors a process variable received via a feedback signal from the plant and uses an error signal representing a setpoint error between the process variable and a setpoint to generate the control signal for the plant. An exponentially-weighted moving average (EWMA) calculator generates EWMA values based on the setpoint error. A normalized index generator uses the EWMA values to calculate a normalized performance index. A threshold generator generates a threshold based on a first alarm parameter κ representing a normalized magnitude of the setpoint error and a second alarm parameter η representing a normalized duration that the setpoint error has persisted. An alarm manager generates an alarm in response to the normalized performance index crossing the threshold.

Abstract: A setpoint alarming system includes a feedback controller that monitors a process variable provided as a feedback signal from a plant and uses an error signal representing a difference between the process variable and a setpoint to generate a control signal for the plant. The plant uses the control signal to affect the process variable. The system includes a normalized index generator that uses the error signal to generate a normalized performance index for the plant. The system includes an expected value estimator that estimates a value of the normalized performance index expected to occur when a setpoint error of a predetermined magnitude has persisted for a predetermined duration. The system includes an alarm manager that compares the normalized performance index to the expected value and generates an alarm in response to the normalized performance index dropping below the expected value.
