Cause
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 reduc-
es power supplied so as not to damage it.
If there is no communication between the boiler and Wire-
less version CAR, an anomaly is signalled. From this mo-
ment, it is only possible to control the system by means of
the control panel of the boiler itself.
The board detects a main supply voltage frequency anoma-
ly
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.
Missing calibration is detected by the P.C.B. It may occur in
the event the P.C.B. is replaced or if the parameters are al-
tered in the air / gas section, thus requiring "complete cali-
bration".
In case of an incorrect boiler wiring connection the error is
detected.
The P.C.B. detects that some parameters have been altered,
thus requiring "fast calibration".
A malfunction of one or both system return and flow
probes is detected.
Boiler status / Solution
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)

Check operation of the Wireless CAR,
check the battery charge (refer to the
relative instructions booklet)
The boiler does not start (1)
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
