Operation can now be monitored via the code window:
With a heat demand:
1 Boiler starts
2 Burner starts
3 Central heating operation; briefly in part load then in full load
When a heat demand ceases:
5 Burner stops
6 Boiler stops
0 Stand-by mode
15 Check and, if necessary, correct the gas/air ratio control
setting.
Perform the check at full load and minimum load for all boiler
models. Only perform settings for the 210-80 and 210-120 models
at minimum load. Perform settings for the 210-160 and 210-200
models at full load and minimum load. An electronic CO
2
or O
2
meter is required for checking and adjustment purposes. Check
that the opening around the probe is properly sealed when meas
urements are taken.
15.a Set full load: press the key, the symbol appears in the
menu bar; if h3 appears in the display, full load has been set.
15.b Now measure the CO
2
percentage and compare it with the
values in table 13. If the CO
2
% level deviates from these
values, set the CO
2
percentage using the screw under the
cap of the V2 coil on the gas block (this can only be adjusted
on the 210-160 and 210-200 models). Check the flame
through the inspection glass (at full load): the flame must not
blow off and the burner's surface must not be red hot.
