Anomaly signalled Cause Boiler status / Solution
0A1 No ignition block
In the event of request of room central heating or domestic hot water
production, the boiler does not switch on within the preset time.
Upon appliance commissioning or aer extended downtime, it may
be necessary to eliminate the block.
Press the Reset button (1)
0A2 Parasite ame block
is occurs during the power-on phase in the event of a leak on the
detection circuit or anomaly in the ame control unit.
Press the Reset button (1)
0A3 Overheating block
During normal operation, if a fault causes excessive overheating inter-
nally, the boiler goes into overheating block.
Press the Reset button (1)
0A4 Air pressure switch
During the heat request phase, the board detects the stuck/open
contacts of the air pressure switch.
Press the Reset button (1)
0A5 Fan signal anomaly is occurs if the fan speed is incorrect. Press the Reset button (1)
0A7
Flue temperature
anomaly
If the boiler fails, the ue circuit will provide an excessively high
temperature reading and the boiler will switch o.
Press the Reset button (1)
0A8 Flame circuit anomaly
During the ignition phase an anomaly was detected on the electronic
ame control circuit and the boiler switches o.
Press the Reset button (1)
0A9
Gas valve electric
circuit anomaly
e board detects an anomaly in the gas valve circuit. Before replacing
the board, verify the absence of short circuits on gas valve and related
connector.
Press the Reset button (1)
0A15
Flow and return NTC
probe temperature
detection incorrect (in
stand-by)
With the boiler in stand-by, the board detects an anomalous dierence
between the NTC probe ow and return temperatures. e error may
be caused by a failure in one of the two probes
Press the Reset button (1)
0A16
Poor thermal ow
NTC probe contact
During boiler operation the board does not detect a change in the ow
NTC probe temperature. e error may be caused by a poor thermal
probe contact or a system with excessive thermal inertia.
Press the Reset button (1)
0A17
Poor thermal return
NTC probe contact
During boiler operation the board does not detect a change in the return
NTC probe temperature. e error may be caused by a poor thermal
probe contact or a system with excessive thermal inertia.
Press the Reset button (1)
0A18
Flow and return NTC
probe temperature
detection incorrect
If the board detects a sudden drop in temperature on one of the two
NTC probes (ow and return), it will report an anomaly. is may be
caused by the failure of one of the two probes
Press the Reset button (1)
0A21 P.C.B. error An error is detected on the P.C.B. and the boiler does not start up Press the Reset button (1)
0A30
Flow NTC probe in
short circuit
e board detects a short circuit on the ow NTC probe. Press the Reset button (1)
0A31
Flow NTC probe
outside the operating
range
e board detects an open contact on the ow NTC probe. Press the Reset button (1)
0A37
Insucient system
pressure
If the system pressure is too low the boiler switches o.
Check on the boiler pressure gauge (1)
that the system pressure is between 1÷1.2
bar and restore the correct pressure if
necessary.
(2) (1)
0A43
Return NTC probe in
short circuit
e board detects a short circuit on the return NTC probe Press the Reset button (1)
0A44
Return NTC probe
outside the operating
range
e board detects an open contact on the return NTC probe. Press the Reset button (1)
0A80
Flow and return NTC
probe connection error
If the electrical connection between the two NTC probes is switched
around, the board will detect the anomaly (it may be necessary to wait
3 minutes for the error to be detected).
Press the Reset button (1)
(1) If the block or anomaly persists, contact an authorised company (e.g. Immergas Technical Aer-Sales Service).
(2) If normal operating conditions are restored, the boiler re-starts without having to be reset.
