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
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 (
