<p>PROBLEM TO BE SOLVED: To provide an easy-to-use controller which efficiently handle current actual trouble. SOLUTION: A system equipped with a system controller to which a plurality of controlled devices are connected is provided with a maintenance button so as to handle trouble which can not be detected in such a case. With the button, trouble items are displayed and when a corresponding trouble item is selectively specified, a CPU performs an estimation process for sequencing its occurrence causes in the decreasing order of probability and further perform a process of preferentially displaying handling information corresponding to higher occurrence probability according to the estimation result; and then a user performs operation, etc., based upon the preferentially displayed handling information to make an efficient recovery to a trouble-removed state.</p> |
