• Operation with Comando Amico Remoto
(CAR V2 ) (Optional). If the CAR
V2
the ( ) symbol will appear on the display.
The boiler regulation parameters can be set via
the CAR V2 control 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 function-
ing state is shown.
Caution: if the boiler is switched "off " the
CAR V2 will display the connection error symbol
"ERR>CM", the CAR V2 is however powered
constantly so as not to lose the stored programs.
• Solar operating mode ( ). This function
is activated automatically id 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

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.
• Operation with optional external probe

external probe, the boiler flow temperature

temperature can be modified by selecting the
functioning curve via the selector switch (6)
(or on the CAR
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.

for 8 seconds, the display switches-off and the
boiler is off completely. The safety functions are
not guaranteed in this mode.
IMPORTANT NOTE: in these conditions the
boiler is considered still live even if there are
no functions active.
• "Automatic vent" mode. Every time the boiler
is electrically powered, the system automatic
vent function is activated (lasting 8 minutes).
This function is displayed via a countdown
signalled by the indicator (14). During this
period the DHW and CH functions are not
active.
Cause
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 neces-
sary to eliminate the block.
During normal operation, if a fault causes excessive overheating internally,
the boiler goes into overheating block.
During normal operation, if a fault causes excessive flue gas overheating,
the boiler blocks.
The P.C.B. detects an anomaly on the gas valve supply. Check the connec-
tion. (the anomaly is detected and displayed only in the event of a request).
The board detects an anomaly on the flow NTC probe.
The board detects an anomaly on the domestic hot water NTC probe.
Number of allowed resets that have already performed.
Water pressure inside the central heating circuit that is sufficient to guar-
antee the correct operation of the boiler is not detected.
If the board detects an anomaly or incongruity on the electric wiring, the
boiler will not start.
This occurs if the fan has a mechanical or electrical fault.
This occurs in the event of a leak on the detection circuit or anomaly in
the flame control unit.

The "automatic vent" can be annulled by press-
ing the "reset" button (4).
• Display operation. The display lights up during
the use of the control panel, after 15 seconds
inactivity, the brightness drops until just the
active symbols are displayed. The lighting mode
can be varied via parameter T3 in the P.C.B.
customisation menu.

2.5 TROUBLESHOOTING.

The Victrix EXA 28 1 ErP - 32 1 ErP boiler
reports any anomalies using a code shown on
the boiler display (14), listed in the table below:
On the remote control, the error code will be
displayed by means of the same numeric code
represented according to the following example
(e.g. CAR V2 = Exx).
Boiler status / Solution
Press the Reset button (1).
Press the Reset button (1).
Press the Reset button (1).
Press the Reset button (1).
The boiler does not start (1).
The boiler continues to produce domestic
hot water but not with optimal perfor-
mance. The antifreeze function is also
disabled (1).
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.
Check on the boiler pressure gauge (1) that
the system pressure is between 1÷1.2 bar
and restore the correct pressure if necessary.
If normal conditions are restored the boiler
restarts without having to be reset. Check
that the boiler is configured correctly (1).
Press the Reset button (1).
Press the Reset button (1).
