From this moment the boiler functions automati-
cally. With no demand for heat (central heating
or domestic hot water production) the boiler
goes to "standby" function, equivalent to the
boiler being powered without presence of ame.
Each time the burner ignites, the relative ame
present symbol is displayed (10) with relative
output scale.

e boiler regulation parameters can be set via
the CAR V2 control panel and the reset button

along with the switch-off button (1) ("off "

ing state is shown.
Caution: if the boiler is switched "o " 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.

• Operation with optional external probe
( ). In the case of a system with optional
external probe, the boiler ow temperature
for room central heating is managed by the
external probe depending on the external
temperature measured (Par. 1.8). The flow
temperature can be modi ed by selecting the
functioning curve via the selector switch (6)

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 a er extended downtime, it may be neces-
sary to eliminate the block.

2.5 TROUBLESHOOTING.

e Victrix EXA 24 X 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
V2
(e.g. CAR = Exx).
Boiler status / Solution
Press the Reset button (1).
Press the Reset button (1).
Press the Reset button (1).
e boiler does not start (1).
e boiler does not start (1).
Attention: the anomaly can be reset 5 times
consecutively, a er 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
o 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.
e boiler does not satisfy the DHW pro-
duction requests (1).
If normal conditions are restored the boiler
restarts without having to be reset. Check
that the boiler is con gured correctly (1).
