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 functioning program customisation phases
are described;
in the third and last part, all operations for displaying and
keeping system functioning under control are described.
FOREWORD.
e “Immergas” “CAR V2 modulating remote control has been
designed to guarantee ideal temperature conditions at any
time of the day and night for each individual day of the week.
Only a few minutes are required for installation: it is connected
to the boiler by just 2 cables, through which, it receives and
sends the adjustment and control commands and receives
the power supply. On completion of installation it is ready to
function thanks to the pre-set program inside. e customer
can modify the basic program according to requirements.
Programming of the "CAR V2" remote control 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
remote control envisioned by the design hypothesis,
the technical features, the installation, assembly,
programming, adjustment and use instructions.
• e system must be in compliance with the Standards in
force.
• e instruction manual must be considered a part of
the CAR V2 remote control and must be “kept for future
reference”.
• Aer having removed the packaging, check the integrity
of the CAR V2 remote control. If in doubt, do not use it
and contact the Dealer or Manufacturer.
• e CAR V2 remote control is destined only for the use
for which it has been expressly designed. Any other use
must be considered improper and therefore dangerous.
• Our products are realised in compliance with the Safety
Standards in force, it is therefore recommended to use all
those devices or attentions in a way that injury/damage
is not caused to persons or objects.

1. INSTALLATION.
1.1 Installation recommendations.
e CAR V2 remote control, including the relative cables and
connections to the boiler, must be installed by specialised
sta. On the initial check of the boiler, when the CAR V2
remote control is inserted into the system, the authorised
aer-sales centre checks the connection to the generator
terminal board and adjusts functioning.
Important: laying of the CAR V2 remote control cables is
excluded from the boiler checks; it is the responsibility of
the installer company.
1.2 Installation operations.
1) Separate the xing template from the body of the CAR
V2 remote control using a screwdriver as a lever in the
relevant recess (Fig. 3). Install the CAR V2 remote control
away from heat sources and in a suitable position to detect
the room temperature correctly (Fig. 1 and 2).
Note: the presence on the rear of the remote control of the
pipe for electric connection cables with the boiler could
recall air from outside the establishment and interfere with
the correct detection of the room temperature (e.g.: boiler
installed outside and use of the suction hood in the kitchen).
Have the job carried out by qualied sta.
2) Install the CAR V2 remote control using the holes made
in the rear of the same directly onto the wall (Fig. 4) or
on a recess box (Fig. 5) using the relative supplied screws.

Important: the xing screws (action n° 3) on rst
installation are no present on the CAR V2 remote
control, but are supplied in a bag present in the
packaging box.
Once the template is xed to the wall, x the body of
the CAR V2 remote control using the 2 screws.

3) To make the electrical connections (Fig. 4) do not operate
when the boiler is live. e connection must be made
respecting the polarity of the wires (+ and -). e jumper
on clamps 40 and 41 of the boiler P.C.B. (if present) must
also be eliminated.
Connect the CAR V2 remote control to the boiler clamps
envisioned at communication with the CAR remote
control or, if not present, to the clamps envisioned for
the CRD.
Note: refer to the electrical connections stated in the
boiler instruction book.
e connection to the boiler is made using two wires (Fig.
5) with minimum section of 0.50 mm2and maximum of
1.5 mm2and with maximum length of 50 metres.
N.B: for correct installation prepare a dedicated line for
the connection of the CAR V2 remote control according
to the Standards in force regarding electrical systems.
If this is not possible interference due to other electric
cables could cause malfunctioning of the CAR V2 remote
control itself.
4) Fix the body of the CAR V2 remote control to the support
template, engaging it with pressure and using the two
screws provided (Fig. 3).
5) Insert 2 1.5 V AA batteries (not supplied) into the pre-set
housing (Fig. 1-8) and close the battery compartment.
6) Aer the boiler has been powered, wait about 30 seconds
before regulation in a way that the communication be-
tween CAR V2 remote control and boiler has established.
