摘要： PROBLEM TO BE SOLVED: To provide an operation diagnosis display which can display the operation diagnosis of an electronic automatic control damper at an easily confirmable place in order to keep good air conditioning. SOLUTION: An operation diagnosis display comprises a damper blade open/ close controller 4 for an electronic automatic control damper, a detector 5 for detecting the opening time required for opening/closing the damper blade 2, a variable timer 7 for setting an arbitrary opening time required for a desired opening/closing amount of the damper blade 2, and an operation diagnostic unit 6 for comparing an opening time detected by the damper blade opening detector 5 with the opening time of the variable timer. Comparison results are presented on a display 15 providing seven kinds of display at an easily confirmable place using the two wire transmission line 16 of a display 9 so that an appropriate operation diagnosis can be made quickly.
