Outdoor unit display
Indoor unit display
• Refer to how to determine below
Criteria
• Wire breaking or failure of the relevant sensor
Cause of problem
■ How to detect OPEN/SHORT error in Low/High pressure sensor
1. During oil retrieval, omit the error detection and start detecting 5 minutes after complete operation.
2. During safety start operation, omit the error detection and start detecting 5 minutes after complete operation.
3. During defrost operation, omit the error detection and start detecting 5 minutes after complete operation
4. SHORT error detection: carry out error detection only if it is under 0.4V.
5. During refrigerant refill/retrieval, omit low pressure sensor error detection.
