panel anomaly
(1) If the shutdown or fault persists, contact an authorised company (e.g. Authorised Technical After-Sales Service)
(2) The anomaly can only be verified in the list of errors in the "Information" menu

Cause
In the event of request of room central heating or domes-
tic hot water production, the boiler does not switch on
within the preset time. Upon appliance commissioning
or after extended downtime, it may be necessary to
eliminate the block.
During normal operation, if a fault causes excessive over-
heating internally, the boiler goes into overheating block.
During normal operation, if a fault causes excessive flue
gas overheating, the boiler blocks
The P.C.B. detects a fault on the gas valve supply. Check
its connection. (the anomaly is detected and displayed
only in the event of a request).
The board detects an anomaly on the flow NTC probe. The boiler does not start (1)
The board detects an anomaly on the domestic hot water
NTC probe. In this case the antifreeze function is also
inhibited
Number of allowed resets already performed.
Sufficient water pressure inside the central heating
circuit to guarantee the correct operation of the boiler
is not detected.
If the board detects an anomaly or incongruity on the
electric wiring, the boiler will not start.
This occurs if the fan has a mechanical or electrical fault. Press the Reset button (1)
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.
Boiler status / Solution
Press the Reset button (1)
Press the Reset button (1)
Press the Reset button (1)
Press the Reset button (1)
In this case the boiler continues to produce domestic hot
water but not with optimal performance (1)
Attention: the fault may be reset up to 5 times con-
secutively, 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 again, the 5 attempts are re-acquired.
Check on the boiler pressure gauge 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. Check that the boiler is con-
figured correctly (1)
Press the Reset button (1)
If normal conditions are restored the boiler restarts
without having to be reset (1).
