11.2 Effective burner anti-cycling times
11.1.6 Setting the maintenance interval
You can define maintenance intervals for the ecoTEC pro.
After the set burner operating hours have elapsed, in addi-
tion to the current flow temperature, the maintenance sym-
bol
(open-end spanner) appears in the display and this
shows that the boiler must be serviced. The display on the
eBUS controller (accessory) shows the information "Mainte-
nance" "MAIN".

11.3 Guideline values for operating hours
> Set the operating hours until the next service using diag-
nosis code "d.084".
Guideline values for the setting can be found in
¬ table 11.3. The values stated correspond to an average
boiler operating time of one year.
You can set the operating hours in increments of ten from
0 to 3,000 h.
If you do not enter a figure under diagnosis 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-
nosis mode.
11.1.7 Setting the by-pass valve
The boilers have a by-pass valve.
The pressure is adjustable in the range between 17.0 MPa
(170 mbar) and 35.0 MPa (350 mbar). Approx. 25.0 MPa
(250 mbar) is pre-set (mid-position). The pressure changes
by approx. 1.0 MPa (10 mbar) each time the adjusting screw
is rotated. By turning right, the pressure increases and turn-
ing left decreases it.
