- modify the corresponding value with push buttons (5) and
(6), consulting the following tables;
- confirm the value set by pressing the Reset push button (1)
for about 5 seconds;
- press the d.h.w. temperature setting push buttons (3) + and
(4) – simultaneously to cancel the operation.
NOTE: if no push buttons are touched for 30 seconds the
operation is cancelled automatically.
Selecting the type of gas. Setting this function is used to adjust
the boiler so it can work with LPG or Natural Gas.

Range of settable values
LG (LPG) o nG (Natural gas) (Standard setting)
Gas G110 - China gas. Setting this function is used to adjust
the boiler so it can work with the first family gases.

Range of settable values
on - oF (Standard setting)
Fixed or correlated d.h.w. set-point (for combi versions
only). By setting the P3 parameter on the on mode, burner
switching off is correlated to the d.h.w. temperature setting. In
the oF mode the burner switches off at the maximum value.

Range of settable values

D.h.w. thermostat (for boilers used for central heating only
in the case of combination with a storage tank). By setting
parameter P3 on the oF mode, boiler ignition for heating do-
mestic water occurs when the temperature of the water inside
the tank drops 3°C compared to the temperature set. In the
on mode, boiler ignition for heating domestic water occurs
when the temperature of the water inside the storage tank
drops 11°C compared to the temperature set.
NOTE: whatever mode is selected the boiler always switches
off at a set point value.
Domestic hot water thermostat
Range of settable values
on - boiler ignition at -11°C
oF - boiler ignition at -3°C (standard setting)

Central heating power. The NIKE Mini 24-28-24 S boilers are
equpped with 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 ranging from the
minimum to the maximum central heating power according
to the system's thermal load.
NOTE: the NIKE Mini 24-28-24 S boilers are manufactured
and calibrated at the nominal output in the central heating
phase. But it takes about 10 minutes to reach 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
