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