Note:
1. The indications in the parenthesis ( ) in the remote control display column are displayed only
when system-down occurs.
2. When a sensor error occurs, check the remote control display to determine which sensor is
malfunctioning.
If the remote control does not indicate the error type, conduct the following operation.
*Turn the power switch off and back on again. If the same LED indication appears again
immediately after the power is turned on, the fault is in the thermistor.
*If the above condition does not result, the fault is in the CT.
3. The indoor unit error indication may take the precedence in the remote control display.
