congruent with the written one, the anomaly
activates.
This anomaly is deactivated if, in view of a new
operation towards the EEPROM, the data is
properly stored.
DISPLAYS
The message "Err." appears alternately with the message
"F096". The
flashing fault symbol is 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 F097
DESCRIPTION
Discordant values for the two NTC sensors of the
flow/safety probe.
ACTIVATION / DEACTIVATION CONDITIONS
The anomaly occurs if the safety microcontroller
detects discordant temperature values for the two
NTC sensors of the dual flow/safety probe.
The anomaly occurs if the safety microcontroller
detects congruent temperature values for the two
NTC sensors of the dual flow/safety probe.
DISPLAYS
"Err." appears alternating with the message "F097". 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 F098
DESCRIPTION
Flow/safety double sensor interrupted or short-circuited
→
flow NTC
ACTIVATION / DEACTIVATION CONDITIONS
The anomaly occurs if the safety microcontroller
detects that the NTC of the flow / safety double
sensor is interrupted or short-circuited.
The anomaly is deactivated if the safety
microcontroller detects that the NTC of the flow /
safety double probe is no longer interrupted or
short-circuited.
DISPLAYS
The message "Err." appears alternately with the message
"F098". The
flashing fault symbol and the
sensor
fault flashing 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 F099
DESCRIPTION
Flow/safety double sensor interrupted or short-circuited
→
safety NTC.
ACTIVATION / DEACTIVATION CONDITIONS
The anomaly occurs if the safety microcontroller
detects that the NTC of the flow / safety double
probe concerning the safety is interrupted or
short-circuited.
The anomaly is deactivated if the safety
microcontroller detects that the NTC of the flow /
safety double sensor related to safety is no longer
interrupted or short-circuited.
