(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
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 (deaerated);
- pump blocked; free the pump.
The board detects an anomaly on the flue probe
This occurs if an incompatible remote control is con-
nected, 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.
This occurs if the ''Flame signal loss'' error occurs many
times in a row within a preset period (38).
The boiler detects a sudden, unexpected increase in the
ΔT between the flow probe and the system return probe.
Should flue high temperature be detected, the boiler
reduces power supplied so as not to damage it.
If there is no communication between the boiler and
Wireless version CAR, an anomaly is signalled. From
this moment, it is only possible to control the system by
means of the control panel of the boiler itself.
The pump is stopped due to one of the following causes:
- Impeller blocked, electrical fault
Air is detected inside the pump; the pump cannot work
In case of an incorrect boiler wiring connection the
error is detected
Possible failure of one or both system return and flow
probes
A malfunction of one or both system return and flow
probes is detected
Boiler status / Solution
Press the Reset button (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.
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)
The power of the burner is limited to prevent damage
to the condensation module and once the right ΔT is
restored, the boiler resumes regular operation. Make sure
there is water circulating in the boiler, that the pump is
configured according to system requirements and that
the return probe works properly. (1) (2)
(1)
Check operation of the Wireless CAR, check the battery
charge (refer to the relative instructions booklet).
Try to unblock the pump as described in the relative
section. If normal conditions are restored the boiler
restarts without having to be reset (1)
Vent the pump and the central heating circuit. If normal
conditions are restored the boiler restarts without having
to be reset (1)
