2.5 USING THE BOILER.
Important: the Mini Nike X 24 3 E boiler has
been designed to operate as an appliance for
room central heating only or, coupled to a specific
optional kit, for central heating and the produc-
tion of DHW. For this reason the boiler control
panel has a button to adjust the temperature of
DHW, but its operation is only activated by the
optional kits that also enable the production of
DHW. Without the coupling of these specific kits,
the functioning of this button and all functions
referring to the DHW are inhibited.
Before ignition, make sure the heating system
is filled with water and that the manometer (7)
indicates a pressure of 1 ÷ 1.2 bar.
- Open the gas cock upstream from the boiler.
- Press the button (2) until the display switches
on, after which press the button in sequence
(2) and take the boiler to the summer ( )
or winter ( ) position.
• Summer ( ) : in this mode the boiler func-
tions only to produce the DHW (when the
boiler is connected to an external cylinder) , the
temperature is set via the buttons (3-4) and the
relative temperature is shown on the display via
the indicator (16).
• Winter
( )
:
in this mode the boiler functions
both for producing domestic hot water (when
the boiler is connected to an external cylinder)
and heating the environment. The temperature
of the DHW is always regulated via buttons
(3-4), the heating temperature is regulated via
buttons (5-6) and the relative temperature is
shown on the display via the indicator (16).
From this moment the boiler functions auto-
matically. With no demand for heat (heating or
domestic hot water production) the boiler goes to
“standby” function, equivalent to the boiler being
powered without presence of flame. Each time
the burner ignites, the relative flame present sym-
bol is displayed (10) with relative power scale.

Operation with Comando Amico Remoto
remote control
V2
(CAR
V2
) (Optional) . If the
CAR
V2
is connected, the ( ) symbol will
appear on the display. The boiler regulation pa-
rameters can be set via the CAR
V2
control panel
and the reset button (1) remains active on the
boiler control panel, along with the switch-off
button (2) (“off” mode only) and the display
where the functioning state is shown.
Important: if the boiler is put into “off” mode
on the CAR
V2
the “CON” connection error
symbol will appear on the CAR. The CAR
V2
is
however powered constantly so as not to loose
memorised programs.
• Functioning with optional external probe
( ) . In the case of a system with optional
external probe, the boiler flow temperature for
room central heating is managed by the exter-
nal probe depending on the external tempera-
ture measured (Par. 1.8). The flow temperature
can be modified by selecting the functioning
curve via buttons (5 and 6), selecting a value
from “0 to 9” (Fig. 1-5).
With external probe present, the relative
symbol will appear on the display (12). In the
central heating phase, if the temperature of the
water contained in the syste m is sufficient to
heat the radiators, the boiler can only function
with the activation of the pump.
• “Stand-by” mode. Press button (2) in suc-
cession until the ( ) symbol appears. The
boiler remains active from this moment and the
anti-freeze function, pump anti-block function
and 3-way and signalling of any anomalies is
guaranteed.
N.B.:
in these conditions the boiler is consid-
ered still live.
•
“Off” mode.
By holding the button (2) down
for 8 seconds, the display switches-off and the
boiler is off completely. The safety functions are
not guaranteed in this mode.
N.B.:
in these conditions the boiler is consid-
ered still live even if there are no functions
active.
• Display functioning. The display lights up dur-
ing the use of the control panel, after 15 seconds
inactivity, the brightness drops until just the
active symbols are displayed. The lighting mode
can be varied via parameter P2 in the circuit
board customisation menu.
2.6 TROUBLESHOOTING.
The boiler signals out anomalies by flashing on
the display and relative error codes, listed on
the table, are displayed. The boiler signals out
anomalies by flashing on the display and relative
error codes, listed on the table, are displayed.
On the remote control, the error code will be
displayed by means of the same numeric code
represented according to the following example
(e.g. CAR
V2
= Exx).

01
No ignition
block
In the event of a request for room central heating or
domestic hot water production, the boiler does not switch on within
the preset time. Upon
the first ignition or after prolonged downtime of the appliance,
an intervention may be required to eliminate the block.
Press the Reset button (1)

During normal operation, if a fault causes excessive internal overheating,
the boiler blocks.

The fume evacuation pipe does not function correctly..
The boiler goes in stand-by for 30 minutes
after which, if the normal operating
conditions are restored, it restarts without
having to be reset. If 3 consecutive blocks
occur, the boiler blocks and it must be rest
for it to restart. (1)
