display (14) according to the following table:

(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 domestic
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 overheating
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 con-
nection. (the anomaly is detected and displayed only in the event
of a request).
The board detects an anomaly on the flow NTC probe.
Number of allowed resets already performed.
Water pressure inside the central heating circuit that is sufficient
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.
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.
The board detects an anomaly on the flue probe
This occurs if an incompatible remote control is connected, or
if communication between the boiler and the remote control
is lost.
Communication between the various components is interrupted
due to an anomaly on the boiler control unit, on the zone control
unit (optional) or on the IMG Bus.
This occurs when the power supply voltage is lower than the
allowed limits for the correct boiler operation.
This occurs when the boiler is ignited correctly and the burner
flame switches off unexpectedly; a new attempt at ignition is
performed and if normal conditions are restored, the boiler
does not have to be reset.
This occurs if the ''Flame signal loss'' error occurs many times
in a row within a preset period (38).
Boiler status / Solution
Press the Reset button (1)
Press the Reset button (1)
Press the Reset button (1)
Press the Reset button (1)
The boiler does not start (1)
The anomaly can be reset 5 times consecu-
tively, 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 re-
set. Check that the boiler is configured
correctly (1)
Press the Reset button (1)
Press the Reset button (1)
If normal conditions are restored the
boiler restarts without having to be reset
(1).
The boiler does not start (1)
Disconnect and reconnect the power to the
boiler. If the Remote Control is still not
detected on re-starting, the boiler will
switch to local operating mode, i.e. using
the controls on the control panel. In this
case the "Central Heating" (1) function
cannot be activated.
The boiler does not satisfy the room heat-
ing requests (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) (2)
Press the Reset button, before restart-
ing, the boiler will run a post-ventilation
cycle. (1)
