2.2 Self-diagnosis by Wired Remote Control

Explanation If operation stops due to malfunction, the remote control’s operation LED blinks, and malfunction code is

displayed. (Even if stop operation is carried out, malfunction contents are displayed when the inspection

mode is entered.) The malfunction code enables you to tell what kind of malfunction caused operation to

stop. See

page 137 for malfunction code and malfunction contents.

Note:

1. Pressing the INSPECTION/TEST button will blink the check indication.

2. While in check mode, pressing and holding the ON/OFF button for a period of five seconds or more

will clear the failure history indication shown above. In this case, on the codes display, the malfunction

code will blink twice and then change to “00” (=Normal), the Unit No. will change to “0”, and the

operation mode will automatically switch from check mode to normal mode (displaying the set

temperature).

3. Subcode is needed to indicate which refrigerant system is causing the error.
