Meaning
High pressure sensor (heat source unit): 1.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. 2.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. 3.During 3-minute antirestart mode, preliminary errors will be displayed o | High pressure sensor (heat source unit): 1.
