DESCRIPTION OF OPERATING
STRATEGIES
Operating the button, the
climate control system sets to automati-
cally control the following functions:
– temperature of the air at the vents
and outlets
– fan speed (constantly changing)
– air distribution
– air recirculation
– compressor engagement.
It is still however possible to intervene
manually on the following functions:
– fan speed
– air distribution
– air recirculation
– compressor engagement.
The functions activated manually have
priority over the automatic ones and they
remain memorised until automatic control
is re-activated.
With one or more functions engaged
manually, adjustment of the temperature
admitted to the passenger compartment
86
still continues to be controlled automati-
cally by the system except with the com-
pressor off: in fact, in this condition the
air admitted to the passenger compart-
ment cannot be below the outside tem-
perature.
Pressing the button for en-
gaging/disengaging automatic operation,
the system may be in one of the follow-
ing conditions:
– FULL AUTO with automatic control
of the fan speed and air distribution;
– AUTO with automatic control only of
the fan speed or of air distribution accord-
ing to the driver's preference;
– MAN with manual operation where
the driver controls the fan speed and air
distribution directly.
Pressing the button turns
the compressor on/off. With the com-
pressor off, the air admitted to the pas-
senger compartment can not be cooled or
dehumidified and recirculation is switched
off automatically to avoid misting the
windows: when wanting to activate recir-
culation in the condition, press the corre-
sponding button.
Pressing the button again
with the compressor off, will restore the
operating conditions of before the com-
pressor was turned off.
Pressing the button turns
off/back on the climate control, in the
former case air is no longer admitted to
the passenger compartment which is thus
isolated from outside, in the latter, the
previous operating mode is restored.
Pressing the button selects
the possible air distributions to the pas-
senger compartment:
Flow of air towards the windscreen
and front side windows
Distribution of the flow between
the windscreen /front side windows and
lower part of the passenger compartment
Flow of air to the lower part of the
passenger compartment and secondary
flow of air towards the windscreen and
front side windows
Distribution of the flow between
the upper centre, centre, side and rear
outlets and the lower part of the passen-
ger compartment
