Anomaly signalled Cause Boiler status / Solution
29 Flue probe anomaly
If the board detects an anomaly on the flue gas probe the boiler will not
start
(1)
31
Loss of remote
control communi-
cation
This occurs in the event of connection to a non compatible remote control
or if there is a communication breakdown between boiler and CAR
V2
or
Super CAR remote control.
Power cycle the boiler. If the Remote Con-
trol is still not detected on re-starting the
boiler will switch to local operating mode,
i.e. using the controls on the control panel.
In this case the “CH ON” function cannot
be activated. To make the boiler work in “”
mode in any case, activate the “P33” func-
tion in the “M3” menu (1) (2).
36
IMG Bus communi-
cation loss
Communication between the control units is interrupted due to an
anomaly on the boiler control unit or on the IMG Bus. The boiler does not satisfy the room heating
requests (1) (2).
37
Low power supply
voltage
This occurs when the power supply voltage is lower than the allowed limits
for the correct boiler operation. If normal conditions are restored the boiler
restarts without having to be reset (1) (2).
38
Loss of flame signal
This occurs when the boiler is ignited correctly and the burner flame
switches off unexpectedly; a new ignition attempt is performed and if
normal conditions are restored, the boiler does not need to be reset (this
fault can be checked in the list of errors in the “M1” menu only).
If normal conditions are restored the boiler
restarts without having to be reset (1) (2).
45
ΔT high
The boiler detects a sudden, unexpected increase in the ΔT between 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
returns to 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 limita-
tion
In the event the heat exchanger is blocked, the boiler reduces the power
supplied so as not to damage it.
(1) (2)
49
High temperature
block on return
probe
This occurs when the heat exchanger return circuit reaches a temperature
that is too high.
Make sure that water circulates properly
in the boiler and that the three-way valve
works properly.
Press the Reset button (1) (2).
(1) If the shutdown or fault persists, contact an authorised company (e.g. Authorised Technical After-Sales Service).
(2) This anomaly is not displayed by the CAR
V2
and Super CAR.
