Ignition Of The Boiler - Immergas MINI EOLO X 24 3 E Instructions And Warnings

2.4

IGNITION OF THE BOILER.

ATTENTION:
the 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 production 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 sum-
mer ( ) or winter ( ) position.
• Summer ( ): in this mode the boiler functions only to heat
the DHW, 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 heating
domestic hot water and heating the environment. The temper-
ature 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 automatically. With no
demand for heat (central heating or domestic hot water pro-
duction) the boiler goes to "standby" function, equivalent to
the boiler being powered without presence of flame. Each time
the boiler ignites, the relative flame present symbol is displayed
(10) with relative power scale.

• Operation with Comando Amico Remoto
(CAR ) (Optional). If the CAR
V2
symbol will appear on the display. The boiler regulation param-
eters can be set via the CAR
(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.
ATTENTION:
if the boiler is put into "off " mode on
the CAR the "CON" connection error
V2
symbol will appear on the CAR
however powered constantly so as not to loose
memorised programs.
• Functioning with optional external probe (
a system with optional external probe, the boiler flow tempera-
ture for room central heating is managed by the external probe
depending on the external temperature measured (Par. 1.10). The
flow temperature can be modified by selecting the functioning
curve via buttons (5 and 6), selecting a value from "0 to 9" (Fig.
34).
With external probe present, the relative symbol will appear on
the display (11). In the central heating phase, if the temperature
of the water contained in the plant is sufficient to heat the ra-
diators, the boiler can only function with the activation of the
boiler pump.
• "Stand-by" mode. Press button (2) in succession 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.
ATTENTION:
in "Stand-by" and "Off " mode, the
boiler is still powered.
• "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.
ATTENTION:
in "Stand-by" and "Off " mode, the
boiler is still powered.
• Display functioning. The display lights up during 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.
