AIR CONDITIONER, ITS CONTROL UNIT, INDICATING PANEL AND MANUFACTURING METHOD OF CONTROL UNIT OF AIR CONDITIONER

摘要

PROBLEM TO BE SOLVED: To make the installation of a jumper wire unnecessary at the time of changing over the function of a main control part according to the specifications in control units with different specifications. SOLUTION: A terminal for distinguishing forms 42 and grounding terminal 43 that are pulled up are formed on indicating panels 28a and 28b with different specifications from each other, and the terminal for distinguishing forms 42 is short-circuited with the grounding terminal 43 by a jumper 43 on the indicating panel 28a with a predetermined specification. The jumper is omitted on the indicating panel 28b with the other specification, and the electric potential of the terminal for distinguishing forms 42 is made high. A main control part 25 determines the electric potential of the terminal for distinguishing 42 and the distinction of the specifications of an air conditioner in which the main control part 25 itself is mounted, and the control of a driving unit is changed on the basis of the result of determination.
