• VICTRIX 50 code 3.015276
NOTE: to correctly install the boiler, use the "Green series" Immergas
air intake/fumes exhaust kit dedicated to the VICTRIX 50 boiler in
both the single and series (bank) congurations.
VICTRIX 50 is the new wall-mounted condensing boiler for
room heating alone. It is pre-engineered for operation both
independently and in series (up to 3 appliances connected),
with the advantage of providing a globally higher efciency at lower running costs. Condensing technology allows
particularly high efciency ratings to be achieved (4 stars,
as established by Directive 92/42/EEC). VICTRIX 50's high
power is ideal when it comes to heating domestic systems
that have to deal with large volumes (semi-detached houses,
small condominiums and apartment blocks) and for commercial and industrial uses. If a single boiler is installed, an
external three-way valve can be connected so as to use it
with a separate water heater and produce domestic hot water. A hydraulic manifold can also be connected to boost the
circulation in the system, thus making it versatile and quick
to install. When operation is in series, several distribution
manifolds can be connected by means of threaded mechanisms. The special environment-friendly burner guarantees
particularly low polluting emissions (the boiler belongs to the
most environment-friendly class established by the European
standards, i.e. class 5).

6 CIRCULATOR HEAD AND FLOW RATE GRAPH
VICTRIX 50 boilers are supplied with built-in circulator and
three-position electric speed governor.
The circulator is the single-phase type (230 V - 50 Hz) are co-
mes already equipped with condenser. In new systems (single
pipe and modules), it is advisable to use the circulator pump
at top speed to obtain optimum operation from the boiler.

7 THERMOREGULATION SYSTEMS (OPTIONAL)
8 SERIES AND ZONE REGULATOR (CODE 3.015244)
Single modular generators or ones installed in series need an
adequate thermoregulation system able to dialogue with the
boiler in a simple way and meet the most varied operating
requirements.
This is why the VICTRIX 50 generator can be tted with a
series of accessories able to optimize the climatic adjustments
made to the entire system.
In short, VICTRIX 50 can be installed with two types of
system:
• In series (with the system divided into one or more zones),
using the series regulator with either the zone controller or
modulating ambient thermostat that regulates the heat in
the individual zones.
• Individually (with the system divided into zones) using the
series regulator with either the zone controller or modulating
ambient thermostat that regulates the heat in the individual
zones. A commercially available timer-thermostat can be
used if there is only one zone.
The Series and zone regulator allows the user to control, monitor and program the operating sequence of the generators
connected. The regulator can be set-up and programmed
using parameters that guarantee ideal temperature conditions at all times of the day and night and throughout every
day of the week for both the heating system and domestic
hot water system (when VICTRIX 50 is used in conjunction
with a water heater). The series regulator can be tted into a
support afxed to a wall.
8.1 SPECIFICATIONS
The electrical connections are made with 2 wires powered at
230V (1.5 mm2 ) in diameter.
2 BUS data cables up to 50 meters in length are used to
connect to the boiler, allowing the device to:
• control up to three zones (2 of which mixed if necessary)
and a separate water heater unit. Since up to 5 series regulators can be installed (of which only one, the so-called
Master, will be connected to the boiler board), systems with
up to a total 15 zones (of which 10 mixed if necessary) and
5 separate water heater units can be controlled;
• enter two ambient temperature values, one for the daytime
(comfort temp.) and one for the night (lower temp.);
• control the temperature of the domestic hot water (in
conjunction with a water heater Unit);
• select the operating mode for the heating and hot water
production functions of each individual hydraulic circuit:
- comfort temperature mode,
- low temperature mode,
- adjustable antifreeze temperature mode;
• control the boiler delivery temperature according to the outdoor temperature (in conjunction with the external probe),
with climatic curve settings;
• obtain information about the system:
- temperature of the system,
- operating mode,
- meter data,
- timer program,
- pump operating status,
- variable input values and operation;
• enter the operating parameters:
- operating times,
- operating mode,
- domestic hot water,
- direct, mixed 1, mixed 2 circuits,
- date and time;
• display operating faults with their relative error codes by
means of the check-control system;
• display the date, time, day of the week and temperature of
the generator.

9 ZONE CONTROLLER (CE 3.015264)
The zone controller only operates in conjunction with the
series regulator. Besides the functions described for the series
thermoregulator, it allows the user to keep all the important
information concerning the operation of the appliance and
heating system under control and particularly ready to hand.
This means that the previously set parameters can be easily
modied without having go go to the place where the series
regulator is installed. the climatic timer-thermostat built
into the remote control panel allows the system's delivery
temperature to be adapted to the effective needs of the place
being heated so as to obtain the required ambient temperature
with the utmost precision and, thus, with evident savings in
running costs. The controller also allows the ambient temperature and effective outdoor temperature to be displayed (this
latter if the external probe is installed). The zone controller is
powered by the series thermoregulator by means of 2 BUS
data cables.
9.1 SPECIFICATIONS
2 BUS data cables up to 50 meters in length are used to
connect to the series and zone regulator, allowing the device
to:
• control up to one zone;
• enter two ambient temperature values, one for the daytime
(comfort temp.) and one for the night (lower temp.);
• control the temperature of the domestic hot water (in
conjunction with a water heater Unit);
• select the operating mode for the heating and hot water
production functions of each individual hydraulic circuit:
- comfort temperature mode,
- low temperature mode,
- adjustable antifreeze temperature mode;
• control the boiler delivery temperature according to the outdoor temperature (in conjunction with the external probe),
with climatic curve settings;
• obtain information about the system:
- temperature of the system,
- operating mode,
- meter data,
- timer program,
- pump operating status,
- variable input values and operation;
• enter the operating parameters:
- operating times,
- operating mode,
- domestic hot water,
- direct, mixed 1, mixed 2 circuits,
- date and time;
• display operating faults with their relative error codes by
means of the check-control system;
• display the date, time, day of the week and temperature of
the generator.

VICTRIX 50
11 EXTERNAL PROBE (CODE 3.015266)
The external probe allows the maximum temperature delivered to the system to be automatically lowered or raised as
the outdoor temperature rises or lowers, thus adapting the
heat supplied to the system to suit the outdoor temperature
variations.
The probe is connected straight to the boiler's terminal board
with two wires. Once connected, it always acts even without
the thermoregulation kit.
10 MODULATING AMBIENT THERMOSTAT (CODE 3.015245)
The modulating ambient thermostat (not a conventional
On/Off model) only operates in conjunction with the series
regulator and allows the user to regulate the ambient temperature of one of the zones into which the system is divided
(both in individual and series installations).
The regulation curve of the ambient temperature in the zone
can be modied by means of the series regulator itself.
The modulating ambient thermostat is powered by the series
thermoregulator via 2 BUS data cables.
10.1 SPECIFICATIONS
2 BUS data cables up to 50 meters in length are used to
connect to the series and zone regulator, allowing the device
to:
• control up to one zone;
• vary the ambient temperature of the zone;
• select the operating mode for the zone heating function:
- xed comfort temperature mode,
- xed low temperature mode,
- operation with the timer program.
