Error code
Mitsubishi Electric PQRY code 5201
No approved translation for this record yet; showing the original text.
Meaning
High-pressure sensor fault (63HS1): If the high pressure sensor detects 0.098MPa [14psi] or less during the operation, the heat source 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 heat source unit makes an error stop, and the error code "5201" will appear. During 3-minute antirestart mode, preliminary errors will be displayed on t | High-pressure sensor fault (BC controller PS1): When a pressure sensor reading of 4.06 MPa [589 psi] or above OR 0.98Mpa[142psi] or below is detected, error codes "5201" OR "5203" will appear. The unit will continue its operation by using other sensors as a backup.
