2.6 TROUBLESHOOTING.
The boiler signals any anomalies via the flashing
symbol (5) along with the “ERRxx” indication
on the indicator (6) where “xx” corresponds to
the error code described in the following table.
One the remote control the error code will be
displayed via the same numeric code represented
according to the following example: CAR
V2
= Exx.
Error
Code
Anomaly signalled Cause Solution
01
No ignition block
In the event of request of room central heating or domestic hot
water production, the boiler does not switch on within the preset
time. Upon appliance commissioning or after extended downtime,
it may be necessary to eliminate the block.
Press the Reset button (1) (2).
02
Safety thermostat
block (overheating),
flame control or
fumes thermofuse
anomaly
During normal operation, if a fault causes excessive overheating
internally, the boiler goes into overheating block.
Press the Reset button (1) (2).
04
Contacts resistance
block
Safety thermostat fault (overheating) or flame control anomaly. The boiler does not start (1) (2).
05
Flow probe anomaly
The board detects an anomaly on the flow NTC probe. The boiler does not start (1) (2).
06
Domestic hot water
probe anomaly
The board detects an anomaly on the domestic hot water NTC probe.
In this case the antifreeze function is also inhibited.
In this case the boiler continues to produce
domestic hot water but not with optimal
performance (1).
08
Maximum N° of reset
Number of allowed resets that have already performed.
Attention:
the anomaly can be reset 5 times
consecutively, after which the function in
inhibited for at least one hour. One attempt
is gained every hour for a maximum of 5
attempts. By switching the appliance on and
off the 5 attempts are re-acquired.
10
Insufficient system
pressure
Water pressure inside the central heating circuit that is sufficient to
guarantee the correct operation of the boiler is not detected.
Check on the boiler pressure gauge (1) that
the system pressure is between 1÷1.2 bar
and restore the correct pressure if necessary.
15 Configuration error
If the board detects an anomaly or incongruity on the electric wiring,
the boiler will not start.
If normal conditions are restored the boiler
restarts without having to be reset (1) (2).
16
Fan anomaly
This occurs if the fan has a mechanical or electrical fault. Press the Reset button (1) (2).
20
Parasite flame block
This occurs in the event of a leak on the detection circuit or anomaly
in the flame control unit.
Press the Reset button (1) (2).
23
Return probe anomaly
The board detects an anomaly on the system return NTC probe. The boiler does not start (1) (2).
24
Push button control
panel anomaly
The board detects an anomaly on the pushbutton panel.
If normal conditions are restored the boiler
restarts without having to be reset (1).
27
Insufficient
circulation
This occurs if there is overheating in the boiler due to insufficient water
circulating in the primary circuit; the causes can be:
- low system circulation; check that no shut-off devices are closed on
the heating circuit and that the system is free of air (deaerated);
- pump blocked; free the pump.
Press the Reset button (1) (2).
36
IMG Bus
communication
failure or CAR
V2
absent
Communication between the control units is interrupted due to an
anomaly on the boiler control unit or on the IMG Bus. Or CAR
V2
not connected.
The boiler does not satisfy the room heating
and cooling 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).
(1) If the block or anomaly persists, contact an authorised company (e.g. Immergas Technical After-Sales Service).
(2) The boiler does not start, the heat pump stays active to satisfy the room heating and cooling requests.
(3) The heat pump does not start, the boiler stays active to satisfy the room heating and domestic hot water production requests.
