type of boiler by means of the relative wiring.
15
The board is configured as instant boiler.
(NO jumper between clamps 7-8 of connector X8).
No
For the VICTRIX 26 2 I boiler check there is NO PRESENCE of the
connection jumper between clamps 7-8 of the connector X8.
Yes
Replace the P.C.B.
ERROR 16
Fan anomaly
16
a
The wiring between the P.C.B. and fan is OK.
Check continuity of the cable on clamp 5 of connector X12.
No
Restore the electric connection/replace the wiring.
Yes
Replace the fan. If the anomaly persists, replace the P.C.B.
16
b
At least 24 VDC is present to clamps 3-1 of the connector X12.
No
Replace the P.C.B.
Yes
The wiring between the P.C.B. and fan is OK.
No
Restore the electric connection/replace the wiring.
Yes
Replace the fan. If the anomaly persists, replace the P.C.B.

c
The wiring between the P.C.B. and fan is OK.
Check continuity of the cable on clamp 4 of connector X12.
No
Restore the electric connection/replace the wiring.
Yes

The pump functions correctly.
N.B.: make sure that the pump functions at maximum speed.
No
See section B
Yes
Any CH system zone valve or cut-off cocks are open.
No
Restore circulation in the CH system by acting on the closed devices
and also check:
- the correct functioning of the boiler by-pass;
- the opening times of any zone valves;
- the correct functioning of any thermostatic valves.
Yes
The NTC flow probe is OK (10 kΩ at 25°C).
No
Replace NTC flow probe.
Yes
Check/clean/replace the main heat exchanger (condensation module). If the anomaly persists, replace the P.C.B.
