Fault and anomaly signals.
The boiler signals out anomalies by flashing on the display and
relative error codes, listed on the table, are displayed.

Cause
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 after extended down-
time, it may be necessary to eliminate the block.
During normal operation, if a fault causes excessive overheating
internally, the boiler goes into overheating block.
This occurs if the fan is blocked or if the intake or drain pipes
are obstructed.
This takes place if the boiler board microprocessor erroneously
recognises a signal.
The board detects an anomaly on the flow probe.
The board detects an anomaly on the domestic hot water NTC
probe.
Number of allowed resets that have already performed.
Water pressure inside the central heating circuit that is sufficient
to guarantee the correct operation of the boiler is not detected.
This occurs in case of a fault in the flue pressure switch or the fan.
If the board detects an anomaly or incongruity on the electric
wiring, the boiler will not start.
This occurs in the event of a leak on the detection circuit or
anomaly in the flame control unit.
The board detects an anomaly on the pushbutton panel.
This occurs if there is overheating in the boiler due to insufficient
water circulating in the primary circuit; the causes can be:
- low system circulation; check that no shut-off devices are closed
on the heating circuit and that the system is free of air (deaer-
ated);
- pump blocked; free the pump.
Boiler status / Solution
Press the Reset button (1).
Press the Reset button (1).
If normal conditions are restored the boiler
restarts without having to be reset (1).
Press the Reset button (1).
The boiler does not start (1).
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.
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
attempts. By switching the appliance on and
off the 5 attempts are re-acquired.
Check on the boiler pressure gauge (1) that
the system pressure is between 1÷1.2 bar and
restore the correct pressure if necessary.
If normal conditions are restored the boiler
restarts without having to be reset (1).
If normal conditions are restored the boiler
restarts without having to be reset. Check that
the boiler is configured correctly (1).
Press the Reset button (1).
If normal conditions are restored the boiler
restarts without having to be reset (1).
If normal conditions are restored the boiler
restarts without having to be reset (1).
