Electric Connection; Remote Controls And Room Chrono-Thermostats (Optional) - Immergas VICTRIX 24 TT 1E Instruction And Warning Book

1.7 ELECTRIC CONNECTION.

The appliance has an IPX5D protection degree,
electrical safety of the appliance is reached only
when it is connected properly to an efficient
earthing system as specified by current safety
standards.
Attention: Immergas S.p.A. declines any respon-
sibility 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.
• Open the control panel connections compart-
ment (Fig. 1-4).
To carry out electrical connections, all you have
to do is open the connections compartment as
follows.
- Remove the front panel (Fig. 3-15b).
- Remove the cover (b fig. 1-4).
1) Loosen the two screws (a).
2) Press the two hooks on the cover (b).
3) Remove the cover (b) from the control
panel (c).
- At this point, it is possible to access the terminal
board (d).
Also ensure that the electrical installation cor-
responds to maximum absorbed power specifi-
cations as shown on the boiler data nameplate.
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 a multi-pole circuit breaker with class III
over-voltage category.
To protect from possible dispersions of DC
voltage one must provide a type A differential
safety device.
When replacing the power supply cable, contact a
qualified company (e.g. the Immergas Authorised
After-Sales Technical Assistance Service). The
power cable must be laid as shown (Fig. 1-3).
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.

Installation with system operating at direct
low temperature. The boiler can directly supply
a low-temperature system by setting the flow
temperature adjustment range "t0" and "t1"
(Par. 3.11). In this situation it is good practice
to insert a relevant safety kit (optional) made up
from a thermostat (with adjustable temperature).
Execute connection to terminal boards 14 and 15,
eliminating jumper X70 (Fig. 3-2). The thermo-
stat must be positioned on the system flow pipe
at a distance of at least 2 metres from the boiler.
1.8 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 (Fig. 1-5).
All Immergas chrono-thermostats are connected
with 2 wires only. Carefully read the user and
assembly instructions contained in the acces-
sory kit.
• On/Off Immergas digital chrono-thermostat.
The chrono-thermostat allows:
- set two room temperature value: one for
daytime (comfort temperature) and one for
nighttime (reduced temperature);
- set a weekly program with four daily switch
on and switch off times;
- select the required operating mode from the
various possible alternatives:
• manual operation (with adjustable tempera-
ture).
• automatic operation (with set programme).
• forced automatic operation (momentarily
changing the temperature of the automatic
programme).
The chrono-thermostat is powered by two 1.5V
LR 6 type alkaline batteries.
• Comando Amico Remoto Remote Control De-
vice (CAR ) with climate chrono-thermostat

function. In addition to the functions described
in the previous point, the CAR
V2
the user to control all the important informa-
tion regarding operation of the appliance and
the heating system with the opportunity to
easily intervene on the previously set parame-
ters, without having to go to where the appli-
ance is installed. The panel is provided with

self-diagnosis to display any boiler functioning
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. The CAR
fed directly by the boiler by means of the same 2
wires used for the transmission of data between
the boiler and device.
Important: if the system is subdivided into zones
using the relevant kit, the CAR
with its climate thermostat function disabled, i.e.
it must be set to On/Off mode.
Comando Amico Remoto Remote Control
or On/Off chrono-thermostat electrical con-
nections (Optional). The operations described
below must be performed after having removed
the voltage from the appliance. Any thermostat
or 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 voltage, otherwise the
P.C.B. would be damaged. Any Comando Amico
Remoto Remote Control
clamps 44 and 41 eliminating jumper X40 on the
P.C:B., paying attention not to invert the polarity
in the connections (Fig. 3-2).
Important: if the Comando Amico Remo-
to Remote Control
chrono-thermostat is used, 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 elimination of this risk
before making the boiler electrical connections.
