Pressing the ECON button disables the
air-conditioning system compressor
function. When this is disabled the LED
on the button switches on and ECON

the ECON function press the button
again; the LED on it switches off. The
air is cooled and/or dehumidified
according to the temperature set.
WARNING: It is not possible to have air
flow in the passenger compartment at
a lower temperature than the outside
air temperature when the compressor
is switched off; Under special
environmental conditions the
windows could fog up quickly.

Description of operating

strategies
During automatic operation, the
system controls the following
functions:
– temperature of the air entering the
compartment
– fan speed (stepless change)
– air distribution
– air recirculatiion function
– ventilation compressor activation.
It is however possible to manually
intervene on the following functions:
– fan speed
– air distribution
– air recirculatiion function
– ventilation compressor activation.
Functions activated manually have
priority over automatic functions and
are stored in the memory until
automatic control is reactivated.
With one or more manually operated
functions, air temperature adjustment
continues to be automatically
controlled by the system, except with
deactivated compressor: under this
condition, the temperature of the air
entering the compartment shall not be
lower than outside temperature.
The system can be operating under
one of the following conditions:
– automatic control of the fan speed
and air distribution (AUTO message
switched on in both sectors of the
display)
– automatic control only of the fan
speed or air distribution, according
to the preferences of the user (AUTO
and MANUAL messages switched on
in the display sectors, indicating
automatic and manual operation)
– manual operation, in which the user
directly controls fan speed and air
distribution (MANUAL message
switches on in both sectors of the
display).
When the ECON button is pressed, the
ventilation compressor is switched off.
With deactivated compressor, the air
entering the compartment cannot be
cooled or dehumidified and the
recirculating air function is
automatically deactivated to avoid
window steaming. Pressing again the
ECON button with disabled
compressor, activates the previous
operating conditions.
Turn knob 3 to OFF to switch off the air
conditioning and heating system; no
air will be delivered to the passenger
compartment that remains isolated
from the outside environment.
