HOW TO USE THE CLIMATE
CONTROL SYSTEM
The system can be switched on in
various ways. We recommend start-
ing by pressing the AUTObutton
and setting the required tempera-
tures on the display.
Since the system controls three
areas of the passenger compartment,
the driver and the front/back pas-
sengers can select different tempera-
ture values, with a maximum differ-
ence accepted by the system of 7 °
C.
In this way, the system will start
working fully automatically to reach
the required temperature as soon as
possible. It will maintain the tem-
perature by adjusting the amount
and distribution pattern of the air let
into the passenger compartment and
manage the recirculation function
and the climate control system com-
pressor.When the system is working auto-
matically, the only possible manual
functions are:
– MONO, to align air temperature
and distribution on the passenger
side or in the back-seat passengers’
area with that on the driver side;
– REAR, to activate the back con-
trol panel;
– √, to switch off the compressor:
in these conditions the system works
only as a heater;
– air recirculation, to keep recircu-
lation always turned on or off;
–-, for faster defrosting/demist-
ing the front windows, rear window,
external rearview mirrors and wind-
screen wiper nozzles;
– (,for defrosting/demisting the
heated rear window and external
rearview mirrors.The temperature, air distribution
and fan speed settings can be
changed at any time during auto-
matic system operation. The system
will automatically adjust to the new
request. When the system is fully
working in automatic mode (FULL
AUTO), if air distribution and/or
flow is changed, definition FULL
disappears. In this way functions
pass from the automatic mode to the
manual mode, until button AUTOis
pressed again. There is only one fan
speed for all the passenger compart-
ment areas and it can be changed
also by operating back controls,
when activated.
With one or more functions manu-
ally on, the air temperature let into
the passenger compartment is auto-
matically managed by the system
unless the climate control compres-
sor is off. In this condition, in fact,
the air inlet into the passenger com-
partment cannot have a lower tem-
perature than that of the external
air.

153
To switch this function off, turn
the temperature knob to the left and
set the required temperature.
– LOfunction (maximum cooling):
it is activated by turning the temper-
ature knob to the left beyond the
minimum value (16 °C). It can be
independently switched on from dri-
ver’s side or from (front/back) pas-
senger’s side or from both sides (also
by selecting the MONOfunction).
This function can be switched on to
speed up cooling the passenger com-
partment by exploiting the system
potential to the maximum. This
function cuts out the heater and
switches the air recirculation and the
climate control compressor on. The
air distribution and the fan speed
are selected according to the envi-
ronmental conditions. All the manu-
ally settings can be adjusted when
the function is on. To switch this
function off, turn the temperature
knob to the right and set the
required temperature.Buttons for adjusting front air
distribution (10, 18 fig. 121)
Press these buttons to manually
select one of the seven possible air
distribution patterns in the front
passenger compartment (right and
left side):
AAir flow to windscreen and front
side window vents for defrosting/
demisting the windows.
FDAir flow to central and side
dashboard vents and the rear vents.
IMPORTANTOn versions equipped
with solar cell operated sunroof
(where provided), to check opera-
tion at first speed of climate control
system fan when the car is parked,
disengage air vents and set air distri-
bution from central dashboard vents
only before leaving the car.
SAir flow to the front and rear
footwells. The air distribution pat-
tern, due to the natural tendency of
heat to move upwards, allows to
heat the passenger compartment up
as fast as possible. Furthermore, it
offers a prompt feeling of warmth to
the coolest parts of the body.Air flow shared between
footwell vents (warmer air)
and central and side dashboard
vents and the rear vents (cooler air).
This air distribution pattern is par-
ticularly useful in middle seasons
(spring and autumn) when it is
sunny.
Air flow shared between the
footwell vents and the windscreen
and front side window
defrosting/demisting vents. This air
distribution pattern ensures a good
heating of the passenger compart-
ment and prevents possible misting
up.
Air flow distribution between
central and side dashboard
vents, rear vents and windscreen
and front side window vents.
Air flow distribution
between all passenger com-
partment vents.
Air distribution setting is displayed
when leds relevant to the selected
button are lit, which will be turned
off in case of fully automatic opera-
tion (FULL AUTO). F

SUPPLEMENTARY
HEATER
The supplementary heater can
work with the engine off or on and it
allows the following:
– to heat the engine coolant before
start up
– to reduce the engine warming up
time after cold starting
– to warm up the passenger com-
partment before departure
– to remove ice or condensate from
the windows.
Using the heater in winter has the
following advantages:
– to reduce engine wear
– to reduce polluting emissions
– to improve comfort during dri-
ving and stops
– to improve safety.The supplementary heater function
is useful to integrate the engine
coolant warming up during driving
in order to reach and keep the opti-
mal working temperature of the pas-
senger compartment heater in the
quickest way, especially if the cli-
mate is extremely cold.
The system is composed of:
– a heating unit
– an electric pump for the engine
coolant circulation
– an exhaust pipe with muffler
– an electric pump metering the
fuels
– a fuel delivery pipe
– a sensor for outside air tempera-
ture.The system is connected to the car
through the engine cooling system,
the fuel system and the electric sys-
tem. The coolant coming out from
the engine is conveyed to the heater
and made flow in the circuit by an
electric pump. The heater burner is
supplied with the car fuel taken
directly from the tank by means of
an electric pulse pump and then
conveyed to the appropriate system
pipe. The heater control unit sup-
plies directly both electric pumps
(fuel and coolant), activates and
checks the heater functions.
The supplementary heating system
works both with the engine running
and the engine stationary. These two
conditions determine the type of sys-
tem operating mode:
– when the engine is stationary the
supplementary heater can work in
“programmable heater” or “parked-
car heater” mode;

163
– when the engine is running the
system works only in “supplemen-
tary heater” mode.
Regardless of the operating mode,
the start up procedure for the sup-
plementary heater, once it has been
activated, is the following:
1- Fan activation for comburant
air, for at least 30 seconds, to venti-
late and oxygenate the combustion
chamber. The fan speed is progres-
sively increased until the average
operating value is reached.
2- After about 30 seconds, the
heater control unit activates the
electric pump metering the fuel and
the comburant air fan is deactivated
for at least 3 seconds, in order to
facilitate fuel burning. A spark plug
starts combustion inside the heater.
3- At this point, there is a com-
bustion stabilizing phase which lasts
around 15 seconds, during which
the fan speed is kept at average
level.4- In the following 50 seconds the
control unit makes the fan reach
nearly its highest speed.
5- Once combustion has stabilized,
the heater control unit deactivates
the plug and the fan reaches its
maximum speed.
6- From now on the plug is used
by the system as a combustion and
flame sensor.
7- Regardless of the operating
mode, the heater extinction proce-
dure is always based on the combus-
tion chamber ventilation for about
30 seconds, in order to eliminate
completely any combustion remain-
der.
IMPORTANTAfter switching the
system off, both automatically or
manually, it can be switched on
again (ON) only approx. 3 minutes
after or when the CONNECT mes-
sage “COOLING DOWN” disap-
pears from the display. IMPORTANTAlthough in a lesser
quantity the heater burns fuel as the
engine. Therefore, to prevent poi-
soning and suffocation the supple-
mentary heater shall never be turned
on, even temporarily, in confined
areas like garages and workshops
not equipped with exhaust fans.
IMPORTANTThe heater must
always be turned off during refu-
elling and at filling stations to pre-
vent the risk of explosions.
IMPORTANTDo not park the car
over flammable materials like paper,
grass or dry leaves: risk of fire.
OPERATION WITH ENGINE
STATIONARY
“Programmable heater” mode
With this operating mode, the sys-
tem heats the engine coolant and the
passenger compartment before
starting the engine, it keeps air recir-
culation closed and activates air dis-
tribution to the windscreen and the
floor by operating the passenger
compartment fan.

164
This function can be activated with
the CONNECT (from the main
SETUP screen) or with the remote
control.
The system works with this mode on
if the following conditions are present
– outside temperature lower than 20
°C
– coolant temperature lower than 50
°C
– ignition key at STOPor removed
– car battery charged
– fuel not in reserve.
When this mode is on, the heater is
deactivated when one of the following
conditions occur:
– end of planned working time
– OFF signal from the remote con-
trol
– manual shutdown by the user
through CONNECT– ignition key at MAR
– partial battery rundown
– fuel in reserve
– malfunction detected by the heater
control unit.
Timed heater activation/
deactivation through CONNECT
Timed heater activation and deacti-
vation can be set through the CON-
NECT. Select and confirm “Heater”
on the main SETUP screen to display
the parked-car heater settings.
Settings available are the following:
– Operate now
– Timer 1
– Timer 2.
To activate/deactivate the required
function, select and confirm it with
the CONNECT right knob.“Operate now”
The option “Operate now” enables
to warm the passenger compartment
with the engine stopped and warm
and the ignition key to MAR, using
the engine coolant, heater coolant cir-
culation pump, automatic air distrib-
ution control (if not set manually) and
closing air recirculation. The timer
cannot be programmed when this
function is on.
To guarantee the required comfort,
this function shall be mainly activated
when coolant is hot enough. When
coolant temperature is lower than 50
°C the control unit starts the heater,
and when temperature is over 70 °C,
the control unit turns the heater off
and lets only the coolant circulation
pump keep on working.

165
The “parked-car heater” mode is
automatically deactivated when one
of the following conditions takes
place:
– engine started
– limit time (around 30 minutes) of
heater and/or coolant pump func-
tioning overcome
– turn off requested by the user
through the CONNECT
– malfunction detected by the heater
control unit
– partial battery run-down or alter-
nator fault.
“Timer 1” and “Timer 2”
The “Timer” options shall be used
to programme two heater daily cycles;
for each cycle enter the time of acti-
vation and the length of operation
both with 5 minute intervals.
Each cycle cannot last more than 60
minutes. The default operation is 15
minutes. The timer works regardless
of the ignition key position.During heater operation, messages
referred to the following conditions
are shown on CONNECT display:
– fuel level in reserve (continue any-
way?)
– fuel level in reserve. Parked-car
heater has been switched off
– parked-car heater not operating
because of cooling down
– parked-car heater not operating
because external temperature is
higher than 20 °C
– parked-car heater not operating
because motor is on
– parked-car heater has been
switched off because of low voltage.IMPORTANTFor safety reasons,
the timer must be programmed/con-
firmed at any activation and con-
firmed not later than 24 hours since
programming. In addition, the user
must confirm every time the timer ac-
tivation. The timer does not automat-
ically correct standard time.
The timer can be in one of the fol-
lowing conditions:
– off: in this condition the timer is
programmable and parameters can be
loaded or adjusted. Loaded parame-
ters should be valued and approved
by CONNECT
– on: activated parameters approved
by CONNECT are stored in the mem-
ory. The user confirms the set cycle
waiting for the programmed activa-
tion moment which is indicated on the
CONNECT display
– active: the heater is working in
“programmable heater” mode con-
trolled by the timer present on the
CONNECT display. When the timer
is activated, the CONNECT records
the system conditions

166
– stationary: with the “programma-
ble heater” mode controlled by the
timer, the system conditions are con-
trolled by CONNECT.
The timer is automatically deacti-
vated if:
– the “programmable heater” mode
function is stopped by CONNECT if,
at the timer start, the “programmable
heater” mode is activated with the re-
mote control
– if the user manually activates the
heater during the timer operation
– if the timer is activated within 3
minutes after the previous heater
shutdown
– if the user manually deactivates
the timer– if the fuel level in the tank is low
when the timer is activated. This con-
dition is indicated with a message
coming from the system and the user
must confirm activation. If the user
does not confirm activation, the timer
is deactivated. The fuel level is indi-
cated by the CONNECT; if this infor-
mation is not available, it is taken into
consideration the last record before
stopping the engine
– if the timer is activated when the
heater operated by the remote control
is activated.
IMPORTANTIf the heater is in
prompt operating mode, the timer is
automatically stopped at the moment
of activation. Parameters set with the
timer are stored in the memory. If the
timer has been deactivated or
stopped, it should be manually reac-
tivated by the user.HEATER ACTIVATION/
DEACTIVATION WITH THE
REMOTE CONTROL (fig. 123)
Activation/deactivation of the heater
can be operated with remote control
A.
The activation signal is issued by the
remote control with a range of around
600 meters and picked up by a spe-
cific antenna placed on the car, then
it is transmitted to the supplementary
heater receiver and sent to CON-
NECT.
IMPORTANTThe maximum re-
mote control range is reached on open
land, while it is reduced in the pres-
ence of buildings.

This control is accepted by CON-
NECT only if:
– outside temperature lower than 20
°C
– coolant temperature lower than 50
°C
– the ignition key is at STOPor re-
moved
– car battery charged
– sufficient fuel level
– the timer is deactivated.
Switching the heater on
To switch the heater on, press the
remote control button ONfor 1 or 2
seconds, while keeping the antenna in
vertical position; the positive or un-
successful activation is indicated by
the remote control red led Bin the fol-
lowing way:
– the led turns on for about 2 sec-
onds = the signal has been correctly
received and the heater has been ac-
tivated– the led flashes for about 2 seconds
= the signal has not been received.
In the latter case you are advised to
move before trying to activate it by
pressing again the ONbutton.
After the confirmation activation,
the led Bwill flash every 2 seconds for
the whole operation cycle duration.
IMPORTANTIf led Bturns on with
green colour, press twice both remote
control buttons ONand OFFwithin 1
second to set the red colour.
Activation length
When pressing the remote control
button ONthe last recorded activa-
tion length is always activated.
To see the recorded length, press at
the same time for three consecutive
times within 1 second, the remote
control buttons ONand OFF, count
the number of flashes of led Bthen
compare them to those shown in the
table below, including also the first
flash appearing the third time you
press the buttons. Default activation length is 30 min-
utes but it can be changed through
the following procedure:
– press at the same time for three
consecutive times within 1 second, the
remote control buttons ONand OFF
– count the number of flashes of led
Bincluding also the first flash ap-
pearing the third time you press but-
tons ONand OFF
– press OFFto set the length suc-
cessive to the set one (press OFFfor
several times to set the required
length in sequence)
– wait for about 10 seconds for timer
storing.
