Anomaly signalled Cause Boiler status / Solution
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 function “CH ON” cannot
be activated. To make the boiler work in
“CH ON” mode in any case, activate the
“P33” function in the “M3” menu (1) (2).
32
Low tempera-
ture zone 2 probe
anomaly
If the board detects an anomaly on the low temperature zone 2 probe, the
boiler cannot work in the affected area.
(1) (2)
33
Low tempera-
ture zone 3 probe
anomaly
If the board detects an anomaly on the low temperature zone 3 probe, the
boiler cannot work in the affected area.
(1) (2)
34
Low temperature
zone 2 safety ther-
mostat intervention
During operation, if a fault causes excessive over-heating internally on
the low temperature zone 2, the boiler does not satisfy the requests of
the interested zone.
If normal conditions are restored the boiler
restarts without needing to be reset (1) (2).
35
Low temperature
zone 3 safety ther-
mostat intervention
During operation, if a fault causes excessive over-heating internally on
the low temperature zone 3, the boiler does not satisfy the requests of
the interested zone.
If normal conditions are restored the boiler
restarts without needing to be reset (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).
(1) If the shutdown or fault persists, contact an authorised firm (e.g. Authorised Technical After-Sales Service).
(2) Error codes over 31 are not shown on the CAR
V2
and Super CAR display.
