3.9 COMPLETE CALIBRATION FUNCTION
Before carrying out complete calibration, ensure that all
the requirements indicated in the relevant paragraphs
have been met (Par. 1.25 e 1.26).
To access this function it is crucial that there are no active requests
for central heating or DHW production and that the boiler is not
in “Stand-by” mode.
In the event of anomaly “62” or “72” (Par. 2.5) the boiler cancels
any requests by itself.
During the various calibration stages, the CO
2
value can be
checked and possibly corrected as described in (Par. 3.10).
The energy produced is dissipated via the heating circuit; alterna-
tively, the energy can be released from the DHW circuit by open-
ing any hot water tap.
In this case the only active temperature control is the
flow probe that limits the maximum temperature exit-
ing the boiler at 90°C, therefore be careful not to get
burned.
The calibration procedure involves various stages:
- nominal heat output calibration;
- intermediate heat output ignition calibration;
- minimum heat output calibration;
- calibration self-check.
Each calibration procedure, if carried out without altering the
parameters, lasts 5 minutes at the most, after which it switches au-
tomatically to the next parameter until the calibration process is
complete.
Once activated, to cancel the complete calibration func-
tion, press the button ( ) for 2 seconds or disconnect
the power supply. The adjustments present before acti-
vating the function will be maintained.
Complete calibration activation procedure.
42
Press and hold buttons “ ”
and “ ” for more than 5 sec-
onds.
43
The display will show two dash-
es “--” flashing. Now enter the
password “62” to activate the
complete calibration (enter the
first digit by pressing the 1-2
buttons ( ) and the second
digit by pressing the buttons
5-6 ( ).
44
Press the “ ” key to activate
calibration.
Once activated, the complete
calibration function has four
phases:
Nominal heat
output: with the function active, the boiler carries out the proce-
dures required to calibrate the appliance at the nominal heat out-
put.
At this stage the display features flashing icons: “ ” and “ ”
and the operating temperature alternated with the current oper-
ating heat output (99%) is displayed; once the parameters are de-
tected and stabilised, the “ ” symbol will start flashing (this
may take a few minutes), meaning that the nominal heat output
settings have been set.
45
Only after the “ ” symbol
flashes is it possible to change
the CO
2
value (Par. 3.10) or
switch to the next heat output
parameter by pressing the “ ”
button.
