The anomaly occurs if:
sensor resistive value
≥ 47 kΩ
The anomaly is deactivated if:
sensor resistive value
<47 kΩ
DISPLAYS
"Err." appears alternating with the message "F033". The
flashing fault symbol and the
flashing sensor fault
symbol are displayed.
DEVICES
Gas valve: Off.
Fan: if foreseen, a post-purge cycle is performed, then it is
deactivated.
Circulation pump: it performs a post-circulation cycle, if
foreseen, then it turns off.
FAULT F034
DESCRIPTION
Short-circuited boiler probe.
ACTIVATION / DEACTIVATION CONDITIONS
The anomaly occurs if:
sensor resistive value
≤ 400 Ω
The anomaly is deactivated if:
sensor resistive value
> 400 Ω
DISPLAYS
"Err." appears alternating with the message "F034". The
flashing fault symbol and the
flashing sensor fault
symbol are displayed.
DEVICES
Gas valve: Off.
Fan: if foreseen, a post-purge cycle is performed, then it is
deactivated.
Circulation pump: it performs a post-circulation cycle, if
foreseen, then it turns off.
FAULT F035
DESCRIPTION
Overheated boiler probe.
ACTIVATION / DEACTIVATION CONDITIONS
The anomaly occurs if:
Flow probe
temperature ≥ Menu 02.Paramet
er 08
The anomaly is deactivated if:
Flow probe temperature < Menu 02.Parameter 08
DISPLAYS
""Err." appears alternating with the message "F035". The
flashing fault symbol and the
flashing sensor fault
symbol are displayed.
DEVICES
Gas valve: Off.
Fan: If the request is still active, the system brings the fan
speed to the ignition speed to try a new burner ignition.
Circulation pump: Off.
FAULT F036
DESCRIPTION
Interrupted flues probe.
ACTIVATION / DEACTIVATION CONDITIONS
The anomaly occurs if:
probe resistive value ≥ 80 k Ω
The anomaly is deactivated if:
probe resistive value <80 k Ω
DISPLAYS
"Err." appears alternating with the message "F036". The
flashing fault symbol and the
flashing sensor fault
symbol are displayed.
DEVICES
Gas valve: Off.
Fan: if foreseen, a post-purge cycle is performed, then it is
deactivated.
Circulation pump: it performs a post-circulation cycle, if
foreseen, then it turns off.
