8 U8 Outdoor unit fan protection stop
9 U6 Compressor overcurrent interruption/Abnormal of power module
10 U7 Abnormality of superheat due to low discharge temperature
11 U9, UH
Abnormality such as overvoltage or undervoltage and abnormal synchronous signal to main circuit/
Current sensor error
12 - -
13 - -
14 Others Other errors (Refer to the technical manual for the outdoor unit.)
Notes:
1. If the beeper does not sound again after the initial 2 beeps to confirm the self-check start signal was received and
the OPERATION INDICATOR lamp does not come on, there are no error records.
2. If the beeper sounds 3 times continuously “beep, beep, beep (0.4 + 0.4 + 0.4 seconds)” after the initial 2 beeps to confirm
the self-check start signal was received, the specified refrigerant address is incorrect.
* The check code in the parenthesis indicates PAR-3xMAA ("x" represents 0 or later) model.
