Note: 1. The error codes in the parenthesis ( ) are displayed only when the system is shut down.
2. When a sensor error occurs, check the remote controller display to determine which sensor
is malfunctioning.
If the remote controller does not indicate the error code, conduct the following procedure.
∗ 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.
