7. Repairs
7.2 List of faults
Code Fault Possible causes Action
03 Flow sensor malfunction
Insufficient water in heat exchanger
Check your water circuit operation and the opening of the By-Pass
valves
Sensor disconnected or defective Reconnect or replace sensor
04 Antifreeze protection
Protection activated when the ambient temperature is too low and
the unit is on standby
No intervention is necessary
05 High pressure protection
Insufficient water flow
Check water pump operation and openings of By-Pass inlet/outlet
valves
Excess refrigerant gas Readjust the refrigerant volume
Defective 4-way valve Replace the 4-way valve
High pressure switch disconnected or defective Reconnect or replace high pressure switch
06 Low pressure protection
Insufficient refrigerant gas Readjust the refrigerant volume
Defective 4-way valve Replace valve
Low pressure switch disconnected or defective Reconnect or replace low pressure switch
