12.2 Effective burner anti-cycling times
12.1.6 Setting the maintenance interval
You can define maintenance intervals for the ecoTEC plus.
Using this function, the message that the boiler must be
serviced appears in the display after a defined, configurable
number of burner operating hours.
After the set burner operating hours have expired, the
maintenance symbol
(open-end spanner) appears next to
the current flow temperature. The display on the eBUS con-
troller ( Accessories) shows the information "Maintenance"
"MAIN".
> Set the operating hours until the next service using diag-
nostics code D.084.
You can see the operating hours in increments of ten from
0 to 3010 h.
If you do not enter a figure under diagnostics code D.084,
but instead enter the symbol "–", then the "Maintenance
display" function is not active.
i
On completion of the set operating hours, you
must set the maintenance interval again in diag-
nostics mode.
