PC
Antifreeze protection
Protection activated when the ambient temperature is
too low and the unit is on standby
No intervention is necessary
E4
High pressure protection
1) Insufcient water ow
1) Check water pump operation and openings of By-Pass inlet/outlet
valves
2) Defective 4-way valve
or excess refrigerant
2) Readjust the quantity of refrigerant
3) Water temperature setting too high
3) Set the required temperature to 5°C above the current temperature
then proceed in increments of 5°.
4) Pressure switch disconnected or defective 4) Reconnect or replace pressure switch
5) Defective PCB 5) Replace PCB
P9
