Programming the integrated P.C.B..
If wanted, some of the EOLO Mini kW Special boiler’s para-
meters can be programmed.
By modifying these parameters the boiler can be adapted to
your own specic requirements.
To access programming, put the main selector switch on Reset
for 15 to 20 seconds (LEDs 2 and 3 will start ashing simul-
taneously after about 10 seconds - wait for them to stop and put
the main selector switch on d.h.w. and c.h.).
Now put the main selector switch back on d.h.w.-c.h. ( ).
Once programming is activated, you enter the rst level where
you can choose the parameter you want to set.
e latter is indicated by the fast ashing of one of the LEDs
between 1 and 8.
Select by turning the d.h.w. temperature knob.
Consult the following table for the LED/parameter associa-
tion:
List of parameters LED ashing (fast)

Once you have chosen the parameter to change conrm selec-
tion by temporarily turning the main selector switch round to
RESET until the LED relative to the parameter switches o
and then release it.
When the ok has been given for the selection, go to the second
level where the value of the parameter selected can be set.
e value is indicated by the slow ashing of one of the LEDs
between 1 to 8.
e value is selected by turning the central heating tempera-
ture knob.
To exit the programming mode, do nothing for 30 seconds
or, if you are on the “parameter setting” level, put the main
selector switch on position .
For the association of the LED to the value, see the following
tables:
Heating output.  e boiler is made and calibrated in the cen-e boiler is made and calibrated in the cen-
tral heating phase at nominal output. In addition, it features
an electronic adjustment that adapts boiler potential to the
home’s actual heating requirements.
is means that the boiler works normally in a variable eld
of gas pressures, ranging from minimum to maximum output
depending on the system’s heating load.
NOTE: selection of the “Minimum heating output” and
“Maximum heating output” parameters, when there is a cen-
tral heating request, allows boiler ignition and powering of
the modulation with current equal to the value of the relative
parameter selected.
