POWER SUPPLY CABLE CAVO ALIMENTAZIONE
Electrical connection: The "Victrix 26 2 I" boiler
has an IPX4D protection rating for the entire
appliance. Electrical safety of the appliance is
reached only when it is correctly connected to an
efficient earthing system as specified by current
safety standards.
Important: Immergas S.p.A. declines any
responsibility for damage or physical injury
caused by failure to connect the boiler to an
efficient earth system or failure to comply with
the reference standards.
Also ensure that the electrical installation
corresponds to maximum absorbed power
specifications as shown on the boiler data-plate.
Boilers are supplied complete with an "X" type
power cable without plug. The power supply
cable must be connected to a 230V ±10% /
50Hz mains supply respecting L-N polarity and
earth connection . This network must also
have an omnipolar circuit breaker with class III
over-voltage category. When replacing the power
supply cable, contact a qualified technician (e.g.
the Immergas After-Sales Technical Assistance
Service). The power cable must be laid as shown
(Fig. 1-4).
In the event of mains fuse replacement on the
P.C.B., use a 3.15A quick-blow fuse. For the
main power supply to the appliance, never use
adapters, multiple sockets or extension leads.
1.5 REMOTE CONTROLS AND
ROOM CHRONO-THERMOSTATS
(OPTIONAL).
The boiler is prepared for the application of room
chrono-thermostats or remote controls, which
are available as optional kits.
All Immergas chrono-thermostats are connected
with 2 wires only. Carefully read the user and
assembly instructions contained in the accessory
kit.
• On/Off digital chrono-thermostat (Fig. 1-6).
The chrono-thermostat allows:
- to set two room temperature values: one for
day (comfort temperature) and one for night
(lower temperature);
- to set up to four on/off differential weekly
programs;
- selecting the required function mode from
the various possible alternatives:
• permanent operation in comfort temp;
• permanent operation in lower temp;
• permanent operation in adjustable anti-freeze
temp.

The chrono-thermostat is powered by two 1.5V
LR 6 type alkaline batteries.
• Comando Amico Remoto Remote Control
V2 V2
Device CAR ) (Fig. 1-7) with climate
chrono-thermostat function. In addition to
the functions described in the previous point,
V2
the CAR panel enables the user to control all
the important information regarding operation
of the appliance and the heating system with
the opportunity of easily intervening on the
previously set parameters without having to
go to the place where the appliance is installed.
The Comando Amico Remoto
Control panel is provided with self-diagnosis
to display any boiler operating anomalies.
The climate chrono-thermostat incorporated
into the remote panel enables the system flow
temperature to be adjusted to the actual needs
of the room being heated, in order to obtain
the desired room temperature with extreme
precision and therefore with evident saving
in running costs. It also allows to display the
effective room temperature and the external
temperature (if external probe is present).
The chrono-thermostat is fed directly by the
boiler by means of the same 2 wires used for
the transmission of data between boiler and
chrono-thermostat.
Important: if the system is divided into zones
using the relevant kit. the CAR V2
with its climate thermostat function disabled, i.e.
it must be set to On/Off mode.
CAR V2 or chrono-thermostat On/Off electric
connection (Optional). The operations described
below must be performed after having removed
the voltage from the appliance. The eventual
On/Off environment chrono-thermostat must
be connected to clamps 40 and 41 eliminating
jumper X40 (Fig. 3-2). Make sure that the On/
Off thermostat contact is of the "clean" type,
i.e. independent of the mains supply, otherwise
the P.C.B. would be damaged. Any CAR

clamps 41 and 44 on the P.C.B. (in boiler),
eliminating jumper X40 and respecting polarity
(Fig. 3-2). Connection with the wrong polarity
prevents functioning, but without damaging the
CAR V2 . The boiler can only be connected to one
remote control.
Important: If the CAR
arrange two separate lines in compliance with
current regulations regarding electrical systems.
No boiler pipes must ever be used to earth the
electric system or telephone lines. Ensure this risk
is eliminated before making the boiler electrical

connections.

V2 Remote
Installation with system operating at direct
low temperature. The boiler can directly feed a
low temperature system by acting on parameters
"S5" and S6" (par. 3.8). In this situation it is good
practice to insert a relevant safety kit (optional)
made up from a thermostat (with adjustable
temperature). The thermostat must be positioned
on the system flow pipe.
