2.5 TROUBLESHOOTING.
The Victrix X TT boiler reports any anomalies
via a code shown on the boiler display (14)
according to the following table:
Error
Code
Anomaly signalled
Cause
Boiler status / 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 down-
time, it may be necessary to eliminate the block.
Press the Reset button (1)
02
Safety thermostat
block (over-temper-
ature)
During normal operation, if a fault causes excessive overheating
internally, the boiler goes into overheating block.
Press the Reset button (1)
03
Flue safety thermostat
block
During normal operation, if a fault causes excessive flue gas over-
heating, the boiler blocks
Press the Reset button (1)
04
Contacts resistance
block
The P.C.B. detects an anomaly on the gas valve supply. Check the
connection. (the anomaly is detected and displayed only in the
event of a request).
The boiler does not start (1)
05
Flow probe anomaly
The board detects an anomaly on the flow NTC probe.
The boiler does not start (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 again, the 5 attempts
are re-acquired.
10
Insu
ffi
cient 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.
12
Storage tank probe
anomaly (optional)
If the board detects an anomaly on the storage tank probe, the
boiler cannot produce domestic hot water and signals the anomaly.
The boiler does not satisfy the DHW
production requests (1).
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 re-
set. Check that the boiler is configured
correctly (1)
16
Fan anomaly
This occurs if the fan has a mechanical or electrical fault.
Press the Reset button (1)
20
Parasite
fl
ame 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)
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).
29
Flue probe anomaly
The board detects an anomaly on the flue gas probe
The boiler does not start (1)
31
Loss of communica-
tion with the CAR
V2
This occurs 1 minute after communication is lost between the
boiler and the CAR
V2
.
Switch the boiler on and off again (1).
36
IMG Bus communica-
tion loss
Communication between the various components is interrupted
due to an anomaly on the boiler control unit, on the zone control
unit or on the IMG Bus.
The boiler does not satisfy the room heat-
ing requests (1).
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 boil-
er restarts without having to be reset (1)
38
Loss of
fl
ame signal
This occurs when the boiler is ignited correctly and the burner
flame switches off unexpectedly; a new attempt at ignition is per-
formed and if normal conditions are restored, the boiler does not
have to be reset.
If normal conditions are restored the
boiler restarts without having to be reset
(1) (2)
43
Block due to loss of
fl
ame signal
This occurs if the ''Flame signal loss'' error occurs many times in
a row within a preset period (38).
Press the Reset button, before restarting,
the boiler will run a post-ventilation
cycle. (1)
44
Block for exceeding
the maximum accu-
mulated time, close
gas valve opening
This occurs if the gas valve remains open for longer than required
for normal operation, without
the boiler switching on.
Press the Reset button (1)
(1) If the block or anomaly persists, contact an authorised company (e.g. Immergas Technical After-Sales Service).
(2)
Th
e anomaly can only be verified in the list of errors in the “Information” menu
