ABSTRACT:
A process is disclosed for checking communications that a controller receives from elements in an HVAC system. The process includes storing the communications and thereafter checking each stored communication against a range of permitted values for that particular communication. The thus checked communication is made available for use by the controller only if it is within the range of permitted values. A count of times that a particular element does not comply with the check is maintained with a warning being generated in the event that the element continues to communicate unacceptable signal values.
