AND CONTROLS
After demisting/defrosting, operate the
controls to keep the required comfort.
IMPORTANT The climate control system
is very useful to speed up demisting since
it dehumidifies the air. Set controls to
demisting function and switch on the cli-
mate control system by pressing button
E; the knob led will turn on.
Window demisting
In the event of considerable outside mois-
ture and/or rain and/or considerable dif-
ferences in temperature inside and outside
the passenger compartment, perform the
following preventive demisting procedure:
❒turn slider Ato red section;
❒turn air recirculation off by turning
knob Dto
Ú;
❒turn slider Cto -or to ®if the
windows do not demist;
❒turn knob Bto 2nd speed.

Press button Ato start this function;
when this function is on the button led is

This function is timed and switches off au-
tomatically after 20 minutes. To cut out
this function press again button A.
IMPORTANT Do not apply stickers on
the inside of the rear window over the
heating filaments to avoid damage that
might cause it to stop working properly.AIR RECIRCULATION
Turn knob Dto
Ò.
This function is particularly useful when
the outside air is heavily polluted (in a traf-
fic jam, tunnel etc.). However, it is better
not to use it for long periods, especially
if there several people in the vehicle.
IMPORTANT The inside air recirculation
system makes it possible (according to the
selected operating modes) to reach the
required “heating” or “cooling” conditions
faster.
Do not use the air recirculation function
on rainy/cold days as it would consider-
ably increase the possibility of the win-
dows misting inside.

Air temperature
adjusting knob (I)
temperatura
Turning the knob
clockwise or counter-clockwise,
respectively raises or lowers the
temperature of the air required in the
passenger compartment.
Set temperature is shown on the
display.
Turning the knob fully clockwise or
counter-clockwise until it reaches the ex-
treme selections HI or LO, the maximum
heating or cooling functions are respec-
tively engaged:
❒HI function (highest heating power):
this is turned on by rotating the temper-
ature knob clockwise and passing the max.
temperature value (32 °C).
This function can be engaged when re-
quiring to heat the passenger compart-
ment as quickly as possible, exploiting the
maximum potential of the system. Under
these conditions, the system is no longer
controlled by the automatic temperature
adjustment system and sets air mixing to
maximum heating by modulating speed
and air distribution.
More particularly, max. fan speed will not
be immediately engaged if coolant is not
hot enough; this to prevent admitting air
that is not warm enough to the passenger
compartment.
All manual settings are possible with this
function on.To switch the function off, simply turn the
knob counter-clockwise and set the re-
quired temperature.
❒LO function (highest cooling power:
this is turned on by rotating the temper-
ature knob counter-clockwise and passing
the min. temperature value (16 °C).
This function can be engaged when re-
quiring to cool the passenger compart-
ment as quickly as possible, exploiting the
maximum potential of the system. Under
these conditions, the system is no longer
controlled by the automatic temperature
adjustment system and sets air mixing to

Air distribution
buttons (B)
Pressing these buttons it
is possible to choose manually one of the
seven possible air distributions:
▲Air flow to the windscreen and front
side window vents to demist or de-
frost them.
˙Air flow at central and side dashboard
vents to ventilate the chest and the
face during the hot season.
▼Air flow towards the front and rear
lower parts of the passenger com-
partment. Due to the natural tenden-
cy of heat to spread upwards, this type
of distribution allows heating of the
passenger compartment in the short-
est time, also giving a prompt feeling
of warmth.
˙Splitting of the air flow between the ▼vents to the lower part of the pas-
senger compartment (warmest air)
and the dashboard centre and side
outlets (coolest air). This air flow dis-
tribution is particularly useful in spring
and autumn when the sun is shining.
▲Splitting of the air flow between the ▼windscreen and front side window
demisting/defrosting vents and the
lower part of the passenger compart-
ment. This type of air distribution al-
lows satisfactory heating of the pas-
senger compartment while preventing
possible misting of the windows.
▲Splitting of the air flow between the
˙windscreen and front side window
demisting/defrosting vents and the
dashboard centre and side outlets.
This air flow distribution enables to
obtain satisfactory cooling of the pas-
senger's compartment and to keep the
required cooling condition in summer.
▲Splitting of the air flow between the ˙windscreen and front side window ▼demisting/defrosting vents, dashboard
centre and side outlets and the lower
part of the passenger compartment.
This air flow distribution enables to
keep good overall comfort conditions
both in summer and in winter.
Lighting up of the relevant button leds
shows the type of air distribution select-
ed.
To restore automatic air distribution con-
trol after a manual selection, press button
AUTO.

IMPORTANT If it is no longer possible to

manual function operation, the set tem-

To restore system automatic control at
any time, after one or more manual ad-
justments, press button AUTO.Air recirculation
on/off button (G)
Air recirculation works
according to the following operating
logics:
❒forced switching on (inside air recir-
culation always on), indicated by the
turning on of the led on the button G
and by symbol íon the display;
❒forced switching off (air recirculation
always off with air inlet from the out-
side), indicated by the turning off of
the led on the button and by symbol
êon the display.
The above operating conditions are ob-
tained by pressing in sequence the air re-
circulation button G.
IMPORTANT The inside air recirculation
system makes it possible to reach the re-
quired heating or cooling conditions faster.

SELF-STANDING
SUPPLEMENTARY
HEATER
(where provided)
Fiat Ducato can be equipped, upon re-
quest, with two different self-standing
heaters: one is totally automatic whereas
the other is programmable.
AUTOMATIC VERSION
The supplementary heater will activate au-
tomatically with engine turned on and
proper engine coolant and outside tem-
perature conditions. Deactivation is always
automatic.
IMPORTANT During periods of low tem-
perature when the device is activated,
check that the fuel level is higher than the
reserve. Otherwise the device could lock
and require the assistance of the Fiat
Dealership.PROGRAMMABLE VERSION
The supplementary heater is totally inde-
pendent from the engine and can be used
to:
❒heat the passenger compartment
when the engine is off;
❒defrost the windows;
❒heat the engine coolant and conse-
quently the engine before starting.The system consists of:
❒diesel burner to heat coolant with ex-
haust fume muffler;
❒metering pump connected to the ve-
hicle fuel pipes to feed the burner;
❒heat exchanger connected to the en-
gine cooling system pipes;
The heater burns fuel in the
same way as the engine,
though, of course, to a lesser degree
and therefore to avoid intoxication
and suffocation, never use the sup-
plementary heater in closed areas,
garages or workshops not equipped
with specific exhaust evacuation de-
vices even for short periods of time.

In cold weather, the supplementary heater
warms and circulates constant tempera-
ture fluid in the engine cooling system for
the time required to ensure optimal en-
gine ignition and passenger compartment
temperature conditions.
The heater can be started automatically
(programmed by means of the digital
timer) or manually by pressing the “heat
now” button on the timer.
When the heater is turned on (automat-
ically or manually), the electronic control
unit operates the fluid circulation pump
and safely ignites the burner according to
preset and controlled modes.
❒control unit connected to the
heater/ventilation unit for automatic
operation;
❒electronic control unit to check and
adjusted the integrated heater burner;
❒digital timer A-fig. 54to start the
heater manually or to program staring
time.The electronic control unit also controls
the circulation pump delivery in order to
reduce initial heating time. When the sys-
tem is operating, the control unit operates
the heater unit fan to the second speed.
Thermal power is adjusted automatically
by the control unit according to the en-
gine coolant temperature.
