Verify Before Replacing Parts
- Confirm the exact Daikin model family and heat reclaim ventilator context before acting on a generic code description.
- Start with the exact model documentation and verify the full operating sequence before replacing parts, particularly around remote temperature setting wire disconnection.
- Use the listed causes as branches to confirm or eliminate with measurements, not assumptions — defective connector contact is a reasonable second branch.
- After the correction, run the system long enough to confirm the heat reclaim ventilator fault does not return under normal load.
