3) Pressure switch disconnected or defective
4) Defective PCB
1) Insufficient water in heat exchanger
2) Defective water flow sensor
3) Defective PCB
1) Water flow rate too low
2) Defective PCB
1) Insufficient refrigerant gas
2) Same causes as fault E4
1) Water flow too low or water intake temperature
too high
2) Defective thermal protection
3) Bad connection
4) Defective PCB

Action
1) Reconnect sensor
2) Replace sensor
3) Replace PCB
Same actions as P3
1) Check water filter and hydraulic circuit
2) Adjust temperature
3) Replace PCB
No intervention is necessary
1) Check water pump operation and openings of By-Pass inlet/outlet
valves
2) Readjust the quantity of refrigerant
3) Set the required temperature to 5°C above the current temperature
then proceed in increments of 5°.
4) Reconnect or replace pressure switch
5) Replace PCB
1) Readjust the quantity of refrigerant
2) Replace valve
3) Reconnect or replace pressure switch
4) Replace PCB
1) Check your water circuit operation and the opening of the By-Pass
valves
2) Replace water flow contactor
3) Replace PCB
1) Check water pump and hydraulic system operation, and the opening
of the By-Pass inlet/outlet valves
2) Replace PCB
1) Readjust the quantity of refrigerant
2) Same actions as fault E4
1) Check water flow or adjust water temperature
2) Replace protection
3) Check connections
4) Replace PCB
Check wiring connections between
remote control and PCB
2) Replace remote control
3) Replace PCB
