High Pressure Sensor Error (Open/Short)
✳ Low pressure/High pressure sensor open/short error detection method
✳ 1. During the oil collection operation, omit the error detection and start the detection after 5 minutes from the completion of
the operation.
✳ 2. During the safety starting operation, omit the error detection and start the detection after 5 minutes from the completion
of the operation.
✳ 3. During the defrost operation, omit the error detection and start the detection after 5 minutes from the completion of the
operation.
✳ 4. Short error detection: Detect an error if under 0.4V.
✳ 5. Omit the low pressure sensor error detection when the refrigerant charging and collection operation.
