1. Error Code
High-pressure sensor fault (63HS1)
2. Error definition and error detection method
If the high pressure sensor detects 0.098MPa [14psi] or less during the operation, the outdoor unit stops once, turns to anti-
restart mode for 3 minutes, and restarts after 3 minutes when the detected high pressure sensor is 0.098MPa [14psi] or more.
If the high pressure sensor detects 0.098MPa [14psi] or less just before the restart, the outdoor unit makes an error stop, and
the error code "5201" will appear.
During 3-minute antirestart mode, preliminary errors will be displayed on the LED display.
A error is not detected for 3 minutes after the compressor start, during defrost operation, or 3 minutes after defrost operation.
