3.13 FAST CALIBRATION.
Th is function allows you to calibrate the boiler automatically
without requiring or giving the possibility to alter the parameters.
Typically “fast calibration” is used after having set the type of fl ue
in menu “F”, which once altered causes anomaly “72”.
N.B.:
before performing quick calibration, ensure that all the
requirements indicated in (Par. 1.23 and 1.24.
N.B.: to access this function it is crucial that there are no active
requests for central heating or DHW production.
In the event of anomaly “62” or “72” (Par. 2.5) the boiler cancels
any requests by itself.
The energy produced is dissipated via the heating circuit; al-
ternatively, the energy can be released from the DHW circuit by
opening any hot water tap.
ATTENTION:
in this case the only active temperature
control is the fl ow probe that limits the
maximum temperature exiting the boiler at
90 ° C, therefore be careful not to get burned.
In order to access the fast calibration stage, set the DHW selec-
tor in the “6 o'clock” position and the heating selector in the “9
o'clock” position, (Fig. 44) and press the “ ” button for
about 8 seconds until the “chimney sweep” function is activated;
then press the “ ” button within 3 seconds. If the temperature
read from the storage tank during this phase is below 60 °C, the
boiler can be switched on.
44
If the energy produced in
the central heating circuit
is to be discharged, turn
the selector to “0” after
the calibration function is
enabled.
Once the quick calibra-
tion function is active, the boiler sequentially carries out the
procedures required to calibrate the appliance with the nominal,
intermediate and minimum heat output values.
45
At this stage, the display
features flashing icons:
“ ”, “ ”, “
” and
“ ” and the operating
temperature will be dis-
played, alternated with
the current operating
heat output.
Th e calibration stages (nominal, intermediate and minimum) pro-
gress automatically and you must wait until calibration is complete.
•
Minimum heat output:
after having calibrated the boiler with
the intermediate heat output, it is calibrated with the minimum
heat output.
At this stage, the display features fl ashing icons: “ ”, “ ”,
“ ” and the operating temperature alternated with the current
operating heat output (0 % );
42
once the parameters are
detected and stabilised, the
frame of the fl ame pres-
ence symbol ( )
will start fl ashing, mea-
ning that the minimum
heat output parameters
have been set.
If is only possible to correct the CO
2
(Par. 3.12) value after the
fl ame presence frame (
) fl ashes, or exit the calibration
phase by pressing “ ”.
• Calibration self-check: once calibration operations are complete,
the boiler runs a self-check for about one minute. During this
check, the boiler can run at different powers and it is not possible
to apply modifications to the operating parameters or to delete
the operation in progress. Moreover, it is important not to cut
the boiler's power.
3.12 CO
2
ADJUSTMENT.
During complete calibration (Par. 3.11), you can modify the
values of CO
2
.
To have an exact value of CO
2
in the fl ue, the technician must
insert the sampling probe to the bottom of the sample point, then
check that the CO
2
value is that specified in the table (Par. 3.3). If
otherwise, change the value as described hereunder:
- during calibration, when the frame of the
fl ame presence starts
fl ashing ( ) (indicating the correct acquisition of the
parameters) it is possible to alter the CO
2
value by pressing the
“ ” button.
43
At this stage, the display
features flashing icons:
“
”, “ ”, “ ”,
“ ”, “ ” and
display of the operating
temperature is alternated
with the set combustion.
- To increase the combustion setting, press button “ ”; to de-
crease it, press the “ ”. As the combustion setting increases,
the CO
2
value decreases and vice-versa.
- Once the parameter has been altered wait for the value to be saved
(displayed via the frame of the fl ame presence symbol fl ashing
).
- To confirm the set value press ” ”.
