Table. 8- THROTTLE position and parameter setting
Checking the combustion values
MAKE SURE THE FRONT CASING IS CLOSED AND THE INTAKE/FUME EXHAUST DUCTS ARE COMPLETELY
ASSEMBLED.
1. Put the boiler in heating or DHW mode for at least 2 minutes. During this period if the flame symbol flashes on the
display, it means that the boiler is performing a calibration. Wait until the flame becomes steady (end of calibration).
2. Activate the TEST mode (see *** 'TEST mode activation' on page 173 ***).
3. By means of a combustion analyzer, connected to the points located on the starting accessories above the boiler,
check that the CO2 content in the fumes, with boiler working at maximum and minimum output, matches that given
in the following table.
4. If the combustion values do not match, perform the
100% calibration
as described in the following paragraph.
5.
Case A:
if the values still do not match, do not activate other calibrations, as the system needs to work longer to be
able to
self-adapt
.
6.
Case B:
if the values still do not match yet, proceed with activation of the parameter
SC12
or
SC13
, depending on
the type of adjustment necessary (see *** '"Sc" - Combustion Control Parameters Menu' on page 178 ***)
