(1) If the block or anomaly persists, contact an authorised company (e.g. Authorized Technical A er-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 a er 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 ue gas overheat-
ing, the boiler blocks
e 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).
e board detects an anomaly on the ow NTC probe.
Number of allowed resets that have already performed.
Water pressure inside the central heating circuit that is su cient to
guarantee the correct operation of the boiler is not detected.
e board detects an anomaly on the storage tank probe
If the board detects an anomaly or incongruity on the electric wiring,
the boiler will not start.
is occurs if the fan has a mechanical or electrical fault.
is occurs in the event of a leak on the detection circuit or anomaly
in the ame control unit.
e board detects an anomaly on the return NTC probe
e board detects an anomaly on the pushbutton panel.
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 (deaerated);
- circulating pump blocked; free the circulating pump.
e board detects an anomaly on the ue gas probe
This occurs if an incompatible remote control is connected, or if
communication between the boiler and the remote control is lost
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.
is 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)
e boiler does not start (1)
Attention: the fault may be reset up to
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 o again, 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.
e boiler cannot produce domestic hot
water (1)
If normal conditions are restored the boiler
restarts without having to be reset. Check
that the boiler is con gured correctly (1)
Press the Reset button (1)
Press the Reset button (1)
e boiler does not start (1)
If normal conditions are restored the boil-
er restarts without having to be reset (1).
Press the Reset button (1).
e 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.
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 restarting,
the boiler will run a post-ventilation
cycle. (1)
