Table. 7- THROTTLE position and parameter setting
Checking the combustion values
MAKE SURE THE FRONT CASING IS CLOSED AND THE FLUE SYSTEM IS CORRECTLY ASSEMBLED & IN-
STALLED TO THE CURRENT REGULATIONS.
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 24).
3. With the boiler working at maximum and then minimum output, connect a calibrated electronic combustion analyser,
to the flue gas sampling point on the appliance conector, check that the CO2 content in the flue, matches that given
in the below table.
4. If the combustion values do not match, perform the
100% calibration
as described in the following paragraph.
5.
Value 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.
Value 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 29)
