(1) If the shutdown or fault persists, contact an authorised company (e.g. Authorised Service Centre)
(2) The anomaly can only be verified in the list of errors in the "Information" menu
(3) Error displayed only on CAR
(4) Error displayed only on Anomalies log
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
CAR Wireless version, an anomaly is signalled. From this
V2
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.
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 "automatic 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 "automatic calibration".
Possible failure of one or both system return and flow
probes
A malfunction of one or both system return and flow
probes is detected.

Cause Boiler status / Solution
(1)
When the temperature detected by the
return probe drops below 70°C, you
may press the Reset button (1)
Check operation of the Wireless
CAR , check the battery charge (refer
V2
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)
