High pressure
EE01
1. Too much refrigerant
1. Discharge excess refrigerant from
the heat pump’s gas system
2. Insufficient airflow
2. Clean the air exchanger
Low pressure fault
EE02
1. Insufficient refrigerant
1. Check if there is any gas leakage,
re-fill the refrigerant
2. Insufficient water flow
2. Clean the air exchanger
3. Filter jammed or capillary
jammed
3. Replace the filter or capillary tube
No water flow
EE03
Low water flow, wrong flow
direction, or flow switch
fault.
Check if that the water supply is
sufficiently high and that it is flowing
in the right direction, otherwise there
may be a fault with the flow switch.
