FAULT F037
DESCRIPTION
Short-circuited flues probe
ACTIVATION / DEACTIVATION CONDITIONS
The anomaly occurs if:
sensor resistive value ≤ 100 Ω
The anomaly is deactivated if:
sensor resistive value> 100 Ω
DISPLAYS
"Err." appears alternating with the message "F037". 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.
29.
FAN FAULTS
These anomalies involve the fan speed.
FAULT F060
DESCRIPTION
Failure at the fan Hall sensor.
ACTIVATION / DEACTIVATION CONDITIONS
The anomaly occurs, if the board detects from the
Hall sensor a number of impulses per second
higher than, or equal to 500.
The anomaly is deactivated if the board detects
from the Hall sensor a number of impulses per
second less than 500.
DISPLAYS
"Err." appears alternating with the message "F060". The
flashing fault symbol and the
flashing symbol of
fan failure are displayed.
DEVICES
Gas valve: Off.
Fan: If the demand is still active, the system tries to bring
the fan to the ignition speed in order to try a new burner
ignition.
FAULT F061
DESCRIPTION
Fan speed out of the expected range (instantaneous
condition).
ACTIVATION / DEACTIVATION CONDITIONS
The anomaly occurs if the fan reached the set-
point of the expected speed but exits, even only
instantly, the permissible range [set-point ± 1000
rev / min].
The anomaly is deactivated if the fan goes back
within the permissible range for the set-point [set-
point ± 1000 rev / min].
DISPLAYS
"Err." appears alternating with the message "F061". The
flashing fault symbol and the
flashing symbol of
fan failure are displayed.
DEVICES
Gas valve: Off.
Fan: If the demand is still active, the system tries to bring
the fan to the ignition speed in order to try a new burner
ignition.
FAULT F062
DESCRIPTION
Fan speed out of the expected range (extended condition).
ACTIVATION / DEACTIVATION CONDITIONS
The anomaly occurs if the fan does not reach the
set-point in the range [set-point ± 1500 rev / min]
for more than 30 consecutive seconds.
The anomaly is deactivated if the fan enters the
permissible range for set-point [set-point ± 1500
revolutions / minute].
