Anomaly signalled
Cause
Boiler status / Solution
38
Loss of flame signal
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.
If normal conditions are restored the boiler
restarts without having to be reset (1) (2)
43
Block due to loss of
flame signal
This occurs if the ''Flame signal loss'' error occurs many times
in a row within a preset period (38).
Press the Reset button, before restarting,
the boiler will run a post-ventilation
cycle. (1)
45
High ΔT
The boiler detects a sudden, unexpected increase in the ΔT be-
tween the flow probe and the system return probe.
The power of the burner is limited to pre-
vent 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)
47
Burner power limitation
Should flue high temperature be detected, the boiler reduces
power supplied so as not to damage it.

51
CAR Wireless
communication failure
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.
Check operation of the Wireless CAR,
check the battery charge (refer to the rela-
tive instructions booklet).
60
Anomaly pump blocked
The pump is stopped due to one of the following causes:
Impeller blocked, electrical fault
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)
61
Air present in the
pump
Air is detected inside the pump; the pump cannot work
Vent the pump and the central heating cir-
cuit. If normal conditions are restored the
boiler restarts without having to be reset (1)
70
Return/flow probe
exchange
In case of an incorrect boiler wiring connection the error is
detected
The boiler does not start (1)
75
Return and/or flow
probe malfunction
Possible failure of one or both system return and flow
probes
The boiler does not start (1)
76
Flow and/or return
probes temperature drift
A malfunction of one or both system return and flow probes is
detected
The boiler does not start (1)
(1) If the block or anomaly persists, contact an authorised company (e.g. Immergas Technical After-Sales Service)
(2) The anomaly can only be verified in the list of errors in the “Information” menu
