Fault And Anomaly Signals - Immergas VICTRIX OMNIA Instructions And Recommendations

2.5 FAULT AND ANOMALY SIGNALS

The boiler signals any anomalies using a code shown on the boiler
display (11) according to the following table:

(1) If the shutdown or fault persists, contact an authorised company (e.g. Authorised Service Centre)
(2) The anomaly can only be verified in the list of errors in the "Information" menu

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 necessary to eliminate the
block. Clogged condensate drain.
During normal operation, if a fault causes excessive over-
heating 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 a fault on the gas valve supply. Check its
connection. (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. In this case only the antifreeze function is in-
hibited
Water pressure inside the central heating circuit that is suf-
ficient to guarantee the correct operation of the boiler is not
detected.
It occurs in the event of failure of the flue gas pressure
switch (electrical contact closed) or fan speed sensor.
NOTE: the flue gas pressure switch contact is checked only
when the burner is ignited.
This occurs in the event of a leak on the detection circuit or
anomaly in the flame control unit.
The board detects an anomaly on the return NTC probe
The board detects an anomaly on the pushbutton panel.
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)
In this case the boiler continues to
produce domestic hot water but not
with optimal performance and with
possible scalding risk(1)
The anomaly can be reset 5 consecu-
tive times, after which the function is
inhibited for at least one hour and it is
possible to try once every hour, for a
maximum of 5 attempts. By switching
the appliance on and off again, the 5
attempts are re-acquired
Check on the boiler pressure gauge
that the system pressure is between
1-1.2 bar and restore the correct
pressure if necessary (1)
If normal conditions are restored the
boiler restarts without having to be
reset (1)
Press the Reset button (1)
The boiler does not start (1)
If normal conditions are restored the
boiler restarts without having to be
reset (1)
