(1) If the shutdown or fault persists, contact an authorised company (e.g. Authorised Service Centre)
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.
The temperature measured by the return probe is above
90°C. The block is with manual reset.
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 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
The power of the burner is limited to
prevent damage to the condensation
module; 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.

The error disappears when the
temperature detected by the return
probe drops below 70°C. Press the
Reset button (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)
