2.5 Fault and anomaly signals.
e boiler signals out anomalies by ashing on the display and
relative error codes, listed on the table, are displayed.
Error
Code
Anomaly signalled Cause Boiler status / Solution
01 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 down-
time, it may be necessary to eliminate the block.
Press the Reset button (1).
02
Safety thermostat
block
(over-temperature),
ame control anomaly
During normal operation, if a fault causes excessive overheating
internally, the boiler goes into overheating block.
Press the Reset button (1).
03 Fan anomaly
is occurs if the fan is blocked or if the intake or drain pipes
are obstructed.
If normal conditions are restored the boiler
restarts without having to be reset (1).
04
General boiler board
anomaly
is takes place if the boiler board microprocessor erroneously
recognises a signal.
Press the Reset button (1).
05 Flow probe anomaly e board detects an anomaly on the ow probe. e boiler does not start (1).
06
Domestic hot water
probe anomaly
e board detects an anomaly on the domestic hot water NTC
probe.
In this case the boiler continues to produce
domestic hot water but not with optimal
performance (1). Moreover, the anti-freeze
function is prevented and an authorised com-
pany must be called.
08 Maximum N° of reset Number of allowed resets that have already performed.
Attention: the anomaly can be reset 5 times
consecutively, after which the function in
inhibited for at least one hour. One attempt
is gained every hour for a maximum of 5 at-
tempts. By switching the appliance on and o
again, the 5 attempts are re-acquired.
10
Insucient system
pressure
Water pressure inside the central heating circuit that is sucient
to guarantee the correct operation of the boiler is not detected.
Check on the boiler pressure gauge (1) that
the system pressure is between 1÷1.2 bar and
restore the correct pressure if necessary.
11
Flue pressure switch
failure
is occurs in case of a fault in the ue pressure switch or the fan.
If normal conditions are restored the boiler
restarts without having to be reset (1).
15 Conguration error
If the board detects an anomaly or incongruity on the electric
wiring, the boiler will not start.
If normal conditions are restored the boiler
restarts without having to be reset. Check that
the boiler is congured correctly (1).
20 Parasite ame
is occurs in the event of a leak on the detection circuit or
anomaly in the ame control unit.
Press the Reset button (1).
24
Push button control
panel anomaly
e board detects an anomaly on the pushbutton panel.
If normal conditions are restored the boiler
restarts without having to be reset (1).
27
Insucient circula-
tion
is occurs if there is overheating in the boiler due to insucient
water circulating in the primary circuit; the causes can be:
- low system circulation; check that no shut-o devices are closed
on the heating circuit and that the system is free of air (deaer-
ated);
- pump blocked; free the pump.
If normal conditions are restored the boiler
restarts without having to be reset (1).
(1) If the block or anomaly persists, contact an authorised company (e.g. Authorised Technical Aer-Sales Service).
