(1) If the shutdown or fault persists, contact an authorised company (e.g. Authorised Service Centre)
(2) The anomaly can only be verified in the list of errors in the "Information" menu
Cause
The board detects an anomaly on the return NTC probe
The board detects an anomaly on the pushbutton panel.
This occurs if there is overheating in the boiler due to insuf-
ficient 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 (deaerated);
circulating pump blocked; free the circulating pump.
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 inter-
rupted due to an anomaly on the boiler control unit, on the
zone control unit 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 re-
stored, 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).
This occurs if the gas valve remains open for longer than
required for normal operation, without the boiler switch-
ing on.
Boiler status / Solution
The boiler does not start (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)
The boiler does not start (1)
Disconnect and reconnect the power
to the boiler. If the Remote Control is
not detected on re-starting the boiler
will switch to "Summer" mode. In this
case the "Central Heating" (1) function
cannot be activated
The boiler does not satisfy the room
heating 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)
Press the Reset button, before
restarting, the boiler will run a
post-ventilation cycle (1)
Press the Reset button (1)
