- press the d.h.w. temperature setting push buttons (3) + and
(4) - simultaneously to cancel the operation;
Note:
if no push buttons are pressed for 30 seconds the
operation is cancelled automatically.
Solar panel selection.
This function is useful for setting the
boiler so that it can work with solar panels.
By setting parameter P0 to
on
“solare” mode, the burner
shut-down is related to the domestic hot water temperature
regulation. In
oF
mode, the burner shut-down occurs at
maximum value.
N.B.:
in combination with a solar valve kit, it is preferable to
set the parameter P0 to
on
“solare” mode.

Post d.h.w. circulation function.
With the post circulation
function active after domestic hot water has been drawn, the
pump is kept working for 2.5 seconds in the Winter phase
and 1.5 seconds in the Summer phase to reduce the formation
of scale.

Central heating power.
The EOLO Star 23 kW boiler featu-
res electronic modulation that adapts boiler power to the real
heat requirements of the home. So the boiler works normally
in a variable range of gas pressures going from the minimum
to maximum central heating power according to the system’s
thermal load.
Note:
the EOLO Star 23 kW boiler is made and calibrated at
the nominal output in the central heating phase. But you need
about 10 minutes for it to reach the nominal heating output,
modifiable by selecting parameter (P6).
Note:
if the “Minimum central heating power” and “Maxi-
mum central heating power” parameters are selected when
there is a central heating request, boiler ignition is allowed
and powering of the modulation coil with a current equal to
the relative value set.
