7.2.5
Determination of maintenance
interval/maintenance display
The ecoTEC electronics incorporate a feature that
enables you to determine the maintenance intervals for
the boiler. This function serves to provide a signal after
a specific, adjustable number of burner operating hours
that the boiler needs to be maintained.
The service signal SEr and the current flow temperature
are shown alternately in the display of the ecoTEC once
the specified number of burner operating hours has
elapsed. The "maintenance" message appears in the
display of the eBUS controller (accessories).

Table 7.3 Guide values for operating hours
The number of operating hours up to the next
maintenance can be set under the diagnosis point
"d.84". Guide values can be taken from table 7.3; these
values comply with an approximate operating time of
one year for the appliance.
The operating hours can be set in steps of ten from 0 to
3000 h.
If the symbol "–" is entered at diagnosis point "d.84"
instead of a numerical value, the "maintenance display"
function is deactivated.
