protection under cooling mode
PP11
1. Water pump failure
2. Water piping blocked
3. Water flow switch seized
High pressure failure
EE01
1.Refrigerant is too much
2. Air flow is not enough
1.Discharge redundant refrigerant
from HP gas system
2.Clean the air exchanger
Low pressure failure
EE02
1.Refrigerant is not enough
2.Water flow is not enough
3. Filter jammed or capillary
jammed
1.Check if there is any gas
leakage , re-fill the refrigerant
2.Clean the air exchanger
3.Replace the filter or capillary
Water flow failure
EE03
Low water flow, wrong flow
direction, or flow switch failure.
Check if the water flow is enough
and flow in right direction, or else
the flow switch could be failed.
