Possible causes
1. Sensor badly connected
2. Sensor defective
3. PCB defective
Same causes as P3
1. Flow rate too low
2. Water temperature at intake too low
3. PCB defective
Protection activated when ambient tempe-
rature is too low and unit is on standby.
1. Insufficient water flow
2. Defective 4-way valve or excess
refrigerant
3. Water temperature setting too high
4. Pressure switch disconnected or
defective
5. PCB defective
1. Insufficient refrigerant
2. Defective 4-way valve
3. Pressure switch disconnected or
defective
4. PCB defective
1. Water flow rate too low
2. Defective water flow sensor
3. PCB defective
1. Water flow rate too low
2. PCB defective
Insufficient refrigerant gas
Same causes as fault E4
1. Water flow rate too low or water intake
temperature too high
2. Defective thermal protection
3. Bad connection
4. PCB defective
1. Bad connection
2. Wired controller defective
3. PCB defective
Troubleshooting
1. Reconnect sensor
2. Replace sensor
3. Replace PCB
Same measures as P3
1. Check water filter and hydraulic circuit
(no cloggings)
2. Adjust temperature
3. Replace PCB
No intervention necessary
1. Check water pump operation or adjust
regulating valve
2. Refill refrigerant
3. Lower water temperature
4. Reconnect or replace pressure switch
5. Replace PCB
1. Refill refrigerant
2. Replace valve
3. Connect or replace pressure switch
4. Replace PCB
1. Check your water circuit operation and
the opening of the bypass valves
2. Replace water flow contactor
3. Replace PCB
1. Check your water circuit operation and
the opening of the bypass valves
2. Replace PCB
1. Refill refrigerant
2. Same measures as fault E4
1. Check water flow rate or adjust water
temperature
2. Replace circuit breaker
3. Check connections
4. Replace PCB
1. Check wiring connection between
controller and PCB
2. Replace controller
3. Replace PCB
