(1) If the block or anomaly persists, contact an authorised company (e.g. Authorized Technical A er-Sales Service).
(2) The anomaly can only be verified in the list of errors in the "Information" menu
Cause
e boiler detects a sudden, unexpected increase in the ΔT between
the ow probe and the system return probe.
Should ue 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.
e 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 ow probes
A malfunction of one or both system return and ow probes is
detected

Boiler status / Solution
e 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 con gured 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).
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)
