HOW TO USE THE INSTRUCTION BOOK
e instruction book has been divided into 3 main parts:
in the rst, for the installer, the assembly and connection
phases of the remote control with the boiler are described;
in the second, all operating program customisation phases
are described;
in the third and last part, all operations for displaying and
keeping system operation under control are described.
FOREWORD
The “CAR V2 Wireless” (Comando Amico Remoto)
modulating remote control has been designed to guarantee
ideal temperature conditions at any time of the day and night
for each day of the week.
Only a few minutes are required for installation: the radio
frequency controlled Base is powered by the boiler and is
connected to the appliance with 2 cables, through which, it
receives and sends the adjustment and control commands
and receives the power supply. Whereas the chrono-
thermostat, with separate battery power supply, must only be
wall mounted and does not require any electrical connection
if not radio frequency acknowledgement with its own Base.
On completion of installation it is ready to function thanks
to the internal pre-set program. e customer can modify
the basic program according to requirements.
Programming the “CAR V2” is extremely easy and a wide
display allows constant control of all values set.
GENERAL RECOMMENDATIONS
is manual has been drawn-up for: the Installer and the
User.
• Carefully read the warnings contained in this document
as they are required to indicate the use of the CAR
V2 envisioned by the design hypothesis, the technical
features, the installation, assembly, programming,
adjustment and use instructions.
• e system must be in compliance with the IEC Standards
in force.
• e instruction manual must be considered part of the
CAR V2 and must be “kept for future reference”.
• Aer having removed the packaging, check the integrity
of the CAR V2. If in doubt, do not use it and contact the
Dealer or Manufacturer.
• e CAR V2 is intended only for the use for which it
has been expressly designed. Any other use must be
considered improper and therefore dangerous.
• Our products are produced in compliance with the Safety

5
Standards in force, it is therefore recommended to use all
devices or attentions in a way that injury/damage is not
caused to persons or objects.
• Do not remove parts of the CAR V2 when it is running.
• Do not use the CAR V2 exposed to heat sources or under
the scorching sun.
• Periodically check the battery charge.
• e manufacturer is relieved from any liability in the
following cases:
a) Incorrect installation.
b) Operating defects of the boiler to which the Remote
Control is applied.
c) Unauthorised modications or interventions.
d) Total or partial failure to comply with instructions.
e) Exceptional events etc.
CASE CLEANING
To clean the case of the CAR V2 use damp cloths. Never use
abrasive or powder detergents.
WARNING

1. INSTALLATION
1.1 Installation recommendations.
e CARV2, including the relative cables and connections
to the boiler, must be installed by specialised sta. On the
free initial check of the boiler, when the CARV2 is inserted
into the system, the Immergas authorised aer-sales centre
checks the connection to the generator terminal board
and adjusts functioning. e free check just of the CARV2
is not envisioned by the Immergas authorised aer-sales
centre is requested successively to the start phase of the
boiler warranty.
Important: installation of the CARV2 base wires are not
included in the free checks of the boiler and is to be carried
out by the installer company.
N.B.: follow the installation sequence by rst installing the
Base and then the CARV2.
1.2 Installation operations.
1) Separate the xing bottom from the lid of the CARV2
Base using a screwdriver as a lever in the relative recess
(Fig. 1-1). Pull the lid manually outwards to separate it
from the bottom.
2) Install the CARV2 Base bottom using the openings on
its rear part onto the wall or onto a recess box using the
relative supplied screws (Fig. 1-2).

N.B.: it is recommended to use in non-critical electro-
magnetic places and in structures consisting of
material that is not mainly metal or shielding. During
installation, pay attention as indicated in Fig. 1-3.

3) To make the electrical connections (Fig. 1-4) do not
operate when the boiler is live. e connection must
be made to the relative clamps and the jumper on
clamps 40 and 41 of the boiler P.C.B. (if present) must
be eliminated.
en connect the base to the boiler clamps envisioned
during communication with the CARV2 or, if not
present, to the clamps envisioned for the CRD
indicated as 40 and 41 or 41 and 44.
Note: refer to the electrical connections stated in the
boiler instruction book.
Important: do not connect to clamps 42 and 43.
e connection to the boiler is made using two wires (Fig.
1-5) with a minimum section of 0.50 mm2and maximum
1.5 mm2and with a maximum length of 50 metres.

N.B: for correct installation prepare a dedicated line for
the connection of the Base according to the Standards in
force regarding electrical systems. If this is not possible,
interference due to other electric cables could cause the
Base to malfunction.
4) Fasten the lid of the CARV2 Base to the support bottom,
engaging it using pressure (Fig. 1-5).
N.B.: when closing the lid, make sure it is aligned correctly
with the bottom.
6) Separate the xing template from the body of the CARV2
using a screwdriver as a lever in the relative recess (Fig.
1-8). Install the CARV2 away from heat sources and in a
suitable position to detect the room temperature correctly
(Fig. 1-6 and 1-7).
7) Install the CARV2 using the openings on its rear part
directly onto the wall or on a recess box using the relative
supplied screws.
8) Fasten the body of the CARV2 to the support template,
engaging it with pressure and using the two screws
supplied (Fig. 1-8).
9) Insert 2 1.5 V AA batteries (not supplied) into the pre-set
housing (Fig. 1-8) and close the battery compartment.
10) e Base and the CARV2 are associated to each other
during the testing phase in the factory. erefore, an
additional radio frequency association procedure is not
necessary.

Important: the xing screws (action n° 3) on rst
installation are not present on the CARV2, but are
supplied in a bag present in the packaging box.
Once the template is xed to the wall, x the body of
the CARV2 using the 2 screws.
