Using The Boiler - Immergas VICTRIX 24 TT 1E Instruction And Warning Book

2.4 USING THE BOILER.

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 (6) until the display switches
on. The boiler now returns to the state prior to
switch-off.
- If the boiler is in stand-by, press the button (6)
again to activate it. If this is not the case, go to
the next point.
- Then press the button (3) in sequence and set
the boiler in the summer ( ) or winter (
) position.
• Summer ( ): in this mode the boiler only
works to produce DHW; the temperature is set
via the selector (1) and the relative temperature
is shown on the display via the indicator (14).
• Winter ( ): in this mode the boiler works
both for producing domestic hot water and for
central heating. The temperature of the DHW is
always regulated via the selector (1), the heating
temperature is regulated via selector (4) and the
relative temperature is shown on the display via
the indicator (14).
From this moment the boiler functions automat-
ically. With no demand for heat (central 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 symbol is displayed (10) with relative
output scale.
• Operation with Comando Amico Remoto
(CAR ) (Optional). If the CAR
V2 V2
the ( ) symbol will appear on the display.
The boiler regulation parameters can be set via
the CAR control panel and the reset button
V2
(2) remains active on the boiler control panel,
along with the switch-off button (6) ("off "
mode only) and the display where the func-
tioning state is shown.
Caution: if the boiler is switched "off " the
CAR will display the connection error symbol

"ERR>CM", the CAR is however powered

constantly so as not to lose the stored programs.
• Solar operating mode ( ). This function
is activated automatically id the boiler detects
a probe on the DHW inlet (optional) or if the
"Solar ignition delay" parameter is more than
0 seconds.
During a withdrawal, if the outlet water is hot
enough or if there is "Solar ignition delay" time,
the boiler does not switch on, the D.H.W. with-
drawal symbol ( ) appears on the display
along with the flashing solar function symbol
( ).
When the water supplied by the solar system
is at a temperature lower than what is set, or
if the "Solar ignition delay" time has elapsed,
the boiler switches on. At this point, the solar
function symbol will go off.
• Operation 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
external probe depending on the external
temperature measured (Par. 1.9). The flow
temperature can be modified by selecting the
functioning curve via the selector switch (4)
(or on the CAR
to the boiler) selecting a value from "0 to 9".
With external probe present, the relative
symbol (18) will appear on the display. In the
central heating phase, if the temperature of the
water contained in the system is sufficient to
heat the radiators, the boiler can only function
with the activation of the pump.
• "Stand-by" mode. Press button (6) repeatedly
until the symbol (
the boiler remains inactive 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 still
powered.
• "Off " mode. By holding the button (6) 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.
• "Automatic vent" mode. Every time the boiler
is electrically powered, the system automatic
vent function is activated (lasting 8 minutes).
This function is displayed via a countdown
signalled by the indicator (14). During this
period the DHW and CH functions are not
active.
The "automatic vent" can be annulled by press-
ing the "reset" button (2).
