Description - SUPPLEMENTARY AIR CONDITIONER - Fiat DUCATO 2.0 16V fino a 02/05

The basic air conditioner is complemented by a supplementary air conditioner to offer all passengers comfortable environmental conditions by taking in cool air even when temperature and relative humidity are high.The supplementary air condition is activated with the basic air conditioner by means of a specific button on the air conditioning system control panel. Special adjustable, positionable direct the air flow toward passengers in the central and rear seating rows.The supplementary air conditioner is activated automatically when the basic air conditioner is turned on.The power supplies are protected by special fuses in the engine bay junction unit, underfacia control unit and optional underfacia control unit.

Operational Description - SUPPLEMENTARY AIR CONDITIONER - Fiat DUCATO 2.0 16V fino a 02/05

The supplementary air conditioner is activated by pressing a key located in climate control unit M070 - pin 4 -. Control unit M070 receives a power supply via the ignition and directly from the battery at pins 3 and 2. The ignition-operated power supply is protected by fuse F31, located in underfacia junction unit B002, and fuse F34, located in the optional underfacia junction unit B101.An activation control from pin 3 of control unit M070 reaches relays J132 and J121. Both relays are excited and supply battery power to switch H100. Relay J132 turns on the first speed automatically to supply fan N084 via resistor O031 - pins 1 and 3. For the second speed, the power supply flows through resistance load O030 - pins 2 and 3 -; while the power supply for the third speed is directed to motor N084 - pin 1 -.The direct battery power supply supplied to relays J121 and 132 is protected by fuse F56, located in optional junction unit B101.767The following figure does not show electrical components belonging to the supplementary Air Conditioner wiring circuit.
