This patent describes, in a combustion control system including a sensor assembly having sensor means for providing an output signal indicative of at lest one parameter of the process, a process controller means. It comprises: input means for receiving the output signals provided by the sensor means, processing means for processing the signals and generating control outputs to maintain a desired operation of the process. The signal processing means including monitoring means for continuously monitoring parameters of the combustion control system including parameters of the sensor means and generating an alarm signal whenever any one of the parameters deviates from a setpoint value, display means controlled by the signal processing means for displaying alarm conditions. The signal processing means including prioritization means for automatically prioritizing the alarms to provide a display of select alarm conditions based on detailed knowledge of internal operations of an analyzer system which is a direct result of a construction of the analyzer system, and the combustion control system and the prioritization means disregard suspect sensor readings through a program contained in a memory of the combustion control system.
