Electrical Connection; Remote Controls And Room Chrono Thermostats Optional - Immergas VICTRIX TERA 24 PLUS Instruction Booklet And Warning

1.8 ELECTRICAL CONNECTION:

e appliance has an IPX5D protection degree;
electrical safety of the appliance is achieved only
when it is connected properly to an e cient
earthing system, as speci ed by current safety
standards.
Attention: the manufacturer declines any
responsibility for damage or physical injury
caused by failure to connect the boiler to an
e cient earth system or failure to comply with
the reference standards.
• Open the control panel connections compart-
ment (Fig. 7).
To carry out electrical connections, all you have
to do is open the connections compartment as
follows (Fig. 7):
- Disassemble the cover (Fig. 52).
- Disassemble the cover (b)
1) Loosen the screw (a).
2) Press the two hooks on the connections
compartment cover.
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 speci -
cations as shown on the boiler data nameplate.
Boilers are supplied complete with an "X" type
power cable without plug. e power supply cable
must be connected to a 230V ±10% / 50Hz mains
supply respecting L-N polarity and earth connec-
tion; this network must also have a multi-pole
circuit breaker with class III overvoltage category.
To protect from possible dispersions of DC volt-
age, it is necessary to provide a type A di erential
safety device.
When replacing the power supply cable, con-
tact a quali ed company (e.g. the Authorised
A er-Sales Technical Assistance Service).
power cable must be laid as shown (Fig. 6).
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.

a low-temperature system by setting the ow
temperature adjustment range "t0" and "t1" (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).
thermostat must be positioned on the system
ow pipe at a distance of at least 2 metres from
the boiler.
1.9 REMOTE CONTROLS AND
ROOM CHRONO THERMOSTATS
OPTIONAL .
e boiler is prepared for the application of room
chrono-thermostats or remote controls, which
are available as optional kits (Fig. 8).
All Immergas chrono-thermostats are connected
with 2 wires only. Carefully read the user and
assembly instructions contained in the acces-
sory kit.
• On/O Immergas digital chrono-thermostat.
e chrono-thermostat allows:
- set two room temperature value: one for day
(comfort temperature) and one for night
(reduced temperature);
- set a weekly programme with four daily
switch on and switch o times;
- selecting the required function 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).
e chrono-thermostat is powered by two 1.5V
LR 6 type alkaline batteries.
• Comando Amico Remoto Remote Control De-
e

function. In addition to the functions described
in the previous point, the CAR

tion regarding operation of the appliance and

Important: if the Comando Amico Remo-

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.
