In the event of a fault/malfunction the message
"AL"
will appear
on the display alternating with the alarm number eg.
"AL 04"
(Domestic Hot Water Sensor Fault).
Before repairing the fault:
– disconnect the appliance from the mains power by setting the
main switch to "OFF"
OFF
Fig. 28
– as a precautionary measure, close the gas isolation valve.
Repair the fault and start-up the boiler again.
NOTE:
after having repaired the fault, when the alarm number
appears on the display together with the message RESET (see
figure), press the button o ( R ) for approximately 3 seconds
to start the appliance up again.
3.5 Display of operating data and counters
Once the boiler is operating a qualified technician can view the
operating data
"In"
and the counters
"CO"
as follows:
– from the operating screen in the mode enabled at that
moment (WINTER n or SUMMER l )
– go into "INFO" by pressing the buttons > and < at the same
time
for more than 3 seconds until
"In"
appears alternating
with
"0.0"
(information number) and
"25"
(eg. value)
From this point, the technician has 2 options:
– scroll through the list of
"info"
and
"counters"
by pressing the
button > . This way, scrolling will be in sequence
– display the “activated alarms” (no more than 10) by pressing
the button < . Once in this section, proceed with button > or < .
When all the values have been displayed, exit the menu by
pressing and holding down the buttons < and o at the same time
for approximately 5 seconds until the initial screen is displayed.
