A method for checking communications that a controller (56, 58, 60) receives from elements (20-54, 62-74) in an HVAC system, 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 (56, 59, 60) only if it is within the range of permitted values. A count of times that a particular element (20-54, 62-74) 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. <IMAGE> |
