fault

Description

Checking / solution

L11

DEF.DT.RET.ECH

PCU

Difference between the return

temperature and the exchanger

temperature too big

Sensor fault

Check the Ohmic value of the sensor

Replace the sensor if necessary

Bad connection

Check that the sensor has been correctly fitted

No water circulation

Vent the air in the heating system

Check the circulation (direction, pump, valves)

Check the water pressure

Check the cleanliness of the heat exchanger

Check that the heating pump is operating

correctly

L12

STB OPEN

PCU

Maximum boiler temperature

exceeded (STB thermostat

maximum)

Air differential pressure switch

has been triggered

Bad connection

Check the wiring between the PCU PCB and the

STB

Check that the SU PCB is correctly in place

Check the electrical continuity of the STB

Check whether the STB has been correctly fitted

STB failure

Replace the STB if necessary

Check that the sensor has been correctly fitted

Check for correct operation

No water circulation

Remove the air from the installation

Check the circulation (direction, pump, valves)

Check the water pressure

Check the cleanliness of the heat exchanger

Check that the heating pump is operating

correctly

Air pressure switch is triggered

Check that the air inlet and flue gas discharge

flues are not blocked

Check that condensate has been removed and

the cleanliness of the siphon
