displayed on the control panel a second time.
Description of the error
Outside temperature sensor
Flow back sensor
Flue gas sensor
Return sensor
Domestic hot water sensor (only for heating only models with
hot water tank)
Solar domestic hot water sensor (if incorporating a solar in­
stallation)
Solar collector sensor (if incorporating a solar installation)
Communication problem between boiler PCB and control
unit. Probable short circuit on the heating.
Address conflict between several control units (internal
anomaly)
Air present in the boiler circuit (anomaly)
Safety thermostat cut-off for overheating (pump blocked or
air in the heating circuit)
Safety thermostat cut-off for overheating
Pressure in hydraulic circuit too high
Pressure in hydraulic circuit too low
Safety cut-off for absence of circulation (check made by a
sensor)
Flame extinguished
Cut-off by flue gas sensor for overheating
Ignition error (4 attempts)
Internal error on heating PCB
General parameter setting error
Fan operation error
Error ACI board
Domestic hot water sensor damaged
General parameter setting error on the solar installation (if in­
corporating a solar installation)
Light incorrect (parasite flame — internal anomaly)
Power supply voltage too low
Fan threshold speed not reached
