Possible Intervention
Check the connections, the wires,
change it or replace the electronic card
Check the connections, the wires,
change it or replace the electronic card
Increase lightly the water flow going into
the heat pump; the effect is to increase
the temperature of the refrigerant in the
evaporator.
Check the connections, the wires,
change it or replace the electronic card
No action required
No action required
Check the water flow
Replace the pressure switch Have
the heat pump checked by a
refrigeration technician
Have the heat pump checked by a
refrigeration technician
Have the heat pump checked by a

Check the connections, the wires,
change it or replace the electronic card
Check the connections and the wires
Check and repair.
Environment problem
Refrigerant leakage
Capillary is half blocked
Check the connections
Put phases in order
Check the connection of signal cable
