AIR CONDITIONING - Description

1.1, 1.2 8v · Automatic Air Conditioning

Description

The control unit manages the automatic climate control system for air distribution and temperature inside the interior compartment, heating/coolign and distributing air into the interior compartment in order to achieve the desired comfort.

The climate control system automatically adjusts the following parameters/functions:

• Air temperature at outlets;
• Air distribution to the vents;
• Fan speed (continuous variation);
• Compressor engagement;
• Recirculation.

The following parameters/functions can be modified manually:

• Temperature;
• Distribution pattern over 5 seats;
• Fan speed;
• Compressor enabled;
• Demist/defrost function;
• Recirculation.

Manual selections always take precedence over automatic selections and are stored until the user deliberately cancels the command (by pressing AUTO), allowing the automatic device to take control over the relevant function.

The manual setting of a function does not adversely affect the control of other functions set to automatic, in particular, the control of the temperature is always automatic when the system is running.

The display of the climate control system functional state is shown through LED and DISPLAY.

The 'MAX DEF function, used for rapid demisting of the windows, is managed by a procedure activated by the relevant button.

The operations activated by this procedure are:

• the DEFROST LED comes on;
• the LEDS/indications relating to the AUTO and recirculation functions are switched off;
• the DEFROST distribution LEDS come on, and the compressor engagement, open Recirculation and HEATED REAR WINDOW are enabled;
• the fully hot (HI) temperature is displayed;
• display of the fan;
• activation of the following controls on the climate control system.

The duration of the procedure is set to 3 minutes from the time when the coolant temperature exceeds 50 degrees.

Manual Air Conditioning

Description

The vehicle climate control system involves a duct/distributor unit with a heater, controlled via the knobs in the dashboard:

• the left knob mechanically controls the mixture flap between hot and cold air;
• the right knob, mechanically operated via a cable, controls the opening of the flaps which regulate the distribution of air flows;
• the two central knobs are as follows: one with electrical control regulates the air ventilation at four different speeds, and the other mechanically regulates the 'recirculation' function of air in the interior compartment, via a flexible cable.

The operation of the different fan speeds is achieved through a resistive divider.

The control panel is lit up when the side lights are on.

The entire system is protected by specific fuses, housed in junction units in the engine compartment and under the instrument panel. A specific relay controls the switching on of the fan.

The fan can only be switched on when the ignition is on.

To obtain a cold interior compartment temperature, in addition to switching on the air conditioner, it is necessary to set the temperature knob to the blue area and regulate the air flow, and possibly set it to recirculation.
