Abstract
The present invention provides a sequencing control strategy for environmental system controllers that takes better advantage of the capabilities of the system elements to enhance performance and reduce operating costs. A state machine controller is implemented by employing digital technology which enables greater accuracy in monitoring system performance and performing diagnostics. This control modality also provides greater tolerance of faults by permitting automatic reconfiguration of the control strategy so as to be independent of malfunctioning components.
