1. How to count the lamp blinking frequency
・The product will repeat blinking with 2-second
intermissions.
・The blinking speed is as follows: on for 0.35 seconds and
off for 0.35 seconds.
While the "timer lamp" (orange), the "clean lamp" (yellow), the "mist and air purification lamp" (yellow) or "monitor
lamp" (yellow) of the indoor unit is blinking, troubleshoot the product while referring to the table below.
2. If you wish to try another operation while the lamp is blinking, operate the START/STOP button on the remote control unit
twice. The first push will reset the indoor microcomputer, while the second will activate the product
(except for the mode in ※1).
[Cautions]
・There is a failure mode displayed only while the self-diagnosis memory is read (※2). Read and check it as necessary.
・ An erroneous connection (a wrong insertion) of terminals A or B of F cable may go undetected.
