appear on the display. The boiler regulation
parameters can be set via the CAR
panel and the reset button (3) remains active
on the boiler control panel, along with the
switch-off button (1) ("off " mode only) and the
display where the functioning state is shown
Important: if the boiler is put into "off "
mode, the "ERR>CM" connection error
V2
symbol will appear on the CAR
however powered constantly so as not to loose
memorised programs.
• Solar functioning mode ( ). This function
is activated automatically if the boiler detects
a probe on the DHW inlet (optional) or if the
"Solar ignition delay" parameter is more than
0 seconds.
During a withdrawal, if the outlet water is
hot enough, the boiler does not switch on,
the DHW withdrawal symbol (
on the display along with the flashing solar
function symbol ( ).
When the water supplied by the solar system
is at a temperature lower than that at which
the boiler is set, the boiler switches on. At this
point, the solar function symbol will stay on
without flashing.
• Functioning with optional external probe
( ). In the case of a system with optional
external probe, the boiler flow temperature
for room central heating is managed by the
external probe depending on the external
temperature measured (Par. 1.6). The flow
temperature can be modified by selecting the
functioning curve via the selector switch (6)
(or on the CAR V2 control panel, if connected
to the boiler) selecting a value from "0 to 9".
With external probe present, the relative
symbol (18) will appear on the display. In the
central heating phase, if the temperature of the
water contained in the system is sufficient to
heat the radiators, the boiler can only function
with the activation of the pump.
• "Stand-by" mode. Press button (1) in
succession until the ( ) symbol appears.
The boiler remains inactive from this moment
and the anti-freeze function, pump anti-block
function and 3-way and signalling of any
anomalies is guaranteed.
N.B.: in these conditions the boiler is
considered still powered.
• "Off " mode. By holding the button (1) down
for 8 seconds, the display switches-off and the
boiler is off completely. The safety functions are
not guaranteed in this mode.
N.B.: in these conditions the boiler is considered
still live even if there are no functions active.
• "Automatic vent" mode. Every time power is
supplied to the boiler. the system automatic
vent function is activated (duration 8 minutes).
This function is displayed via countdown
signalled by the indicator (14). During this
period the DHW and CH functions are not
active.
The "automatic vent" can be annulled by
pressing the "reset" button (4).

just the active symbols are displayed. The

2.5 FAULT AND ANOMALY SIGNALS.
The Victrix 26 2 I boiler signals any anomalies
using a code shown on the boiler display (14)
according to the following table.

N.B.:on the Comando Amico Remoto
control (Optional), the error code corresponds
to the previous list with the "ERR>" indication in
front (E.g. code 01 CAR
Ignition block. The boiler ignites automatically
with each demand for room central heating or
hot water production. If this does not occur
within the pre-established time, the boiler goes
into no ignition block. To eliminate "no ignition
block" the Reset button (3) must be pressed. On
commissioning or after extended inactivity it
may be necessary to eliminate the "no ignition
block". If this phenomenon occurs frequently,
contact a qualified technician for assistance
(e.g. Immergas After-Sales Technical Assistance
Service).
Safety thermostat block (over-heating), flame
control anomaly. During regular operation, if a
fault causes excessive overheating internally or
an anomaly occurs in the flame control section,
an overheating block is triggered in the boiler. To
eliminate "overheating block" the Reset button
(3) must be pressed. If this phenomenon occurs
frequently, contact a qualified technician for
assistance (e.g. Immergas After-Sales Technical
Assistance Service).
Error
code
Flue safety thermostat block. This occurs in
the case of partial internal obstruction (due to
01
the presence of lime scale or mud) or external
blocking should occur (combustion residues)
02
to the condensation module. To eliminate the
"flue thermostat block" the Reset button (3)
03
must be pressed. Call an authorised technician
to remove the obstructions (e.g. Immergas After-
04
sales Service).
Contacts resistance block. This occurs in the
05
case of faults to the safety thermostat (over-
temperature) or anomaly in the flame control.
06
The boiler does not start and a technician must
be called (e.g. Immergas After-Sales Service).
08
System flow probe anomaly.If the board detects
10
an anomaly on the system NTC flow probe, the
boiler will not start; contact a qualified technician
15
for assistance (e.g. Immergas After-Sales Service).
Domestic hot water probe anomaly. If the board
16
detects an anomaly on the domestic hot water
NTC probe, the boiler signals the anomaly. In this
20
case the boiler continues to produce domestic
hot water but not with optimal performance.
24
Moreover, the anti-freeze function is prevented
and an authorised technician must be called (e.g.
25
Immergas After-Sales Service).
Maximum N° of reset. To eliminate any
27
anomaly, the Reset button (3) must be pressed.
The Anomaly can be reset 5 times consecutively,
29
after which the function in inhibited for at least
one hour. One attempt is gained every hour for
31
a maximum of 5 attempts.
Insufficient system pressure. Water pressure
36
inside the central heating system that is sufficient
to guarantee the correct functioning of the boiler
37
is not detected. Check on the boiler manometer
(7) that the system pressure is between 1÷1.2
38
bar and restore the correct pressure if necessary.
43
Configuration error. If the board detects an
anomaly or incongruency on the electric wiring,
44
the boiler will not start. If normal conditions are
restored the boiler restarts without having to be
reset. If this anomaly persists, contact a qualified
46
technician for assistance (e.g. Immergas After-
Sales Service).
