Check method

On the remote control (Wired remote control, Central control remote control) and the interface P.C. board of the

outdoor unit (I/F), a check display LCD (Remote control) or 7-segment display (on the outdoor interface P.C. board)

to display the operation is provided. Therefore the operation status can be known. With this self-diagnosis function,

a trouble or position with error of the air conditioner can be found as shown in the table below.
