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 probe.
Yes
The safety thermostat functions regularly (intervention temperature
higher than 100°C).
No
Replace the over-heating safety thermostat.
Yes
There are no combustion products in the air intake pipe.
N.B.: check the absence of CO
2
or other combustion products in the
intake pipe.
No
Check the correct positioning of the terminals, of all joints and
gaskets, to prevent the recirculation of the combustion products inside
the pipes.
N.B.: Error 02 could be preceded by the disply of error 38.
Yes
Check/clean/replace the main heat exchanger (condensation module).
N.B.: it is recommended to check the correct pressure of the inlet gas and check any obstructions of the gas piping upstream from the boiler. Error 02 intervenes
also if the board detects a loss of the flame signal 6 times in 8.5 minutes.
ERROR 05
NTC flow probe anomaly
The wiring between the flow probe and the board (connector X11 ter-
minals 3-4) is OK.
No
Restore the electric connection/replace the wiring.
Yes
Replace the NTC flow probe. If the anomaly persists, replace the P.C.B.
ERROR 08
Reset selector switch fault
The main selector is blocked on Reset.
No
Check that there is no interference between the knob and P.C.B.
Yes
Replace the P.C.B.
ERROR 10
Insufficient system pressure
The boiler manometer displays a pressure exceeding 0.8 bar.
No
Restore the correct pressure by acting on the system filling valve.
N.B.: in this case it is always advisable to ensure that there are no leaks
in the central heating plant and check the correct factory-set value of the
expansion vessel.
Yes
The wiring between the system pressure switch (connector X8 terminals
1-2) is OK.
No
Restore the electric connection/replace the wiring.
Yes
Check/replace the system pressure switch. If the anomaly persists, replace the P.C.B.
ERROR 12
Storage tank NTC probe anomaly
The boiler prevents functioning in DHW mode but can function in CH mode
The wiring between the DHW probe and the board (connector X8
terminals 5-6) is OK.
No
Restore the electric connection/replace the wiring.
Yes
Replace DHW NTC probe. If the anomaly persists, replace the P.C.B.
