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 specific requirements.
To access programming, put the main selector switch on Reset
for 15 to 20 seconds (LEDs 2 and 3 will start flashing 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 first level where
you can choose the parameter you want to set.
The latter is indicated by the fast flashing 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:

Once you have chosen the parameter to change confirm selec-
tion by temporarily turning the main selector switch round to
RESET until the LED relative to the parameter switches off
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.
The value is indicated by the slow flashing of one of the LEDs
between 1 to 8.
The 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.
Th e boiler is made and calibrated in the cen-
The 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.
This means that the boiler works normally in a variable field
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.
