312001111 - E6020 AIR CONDITIONER - DESCRIPTION (Manual air conditioning)
DESCRIPTION
The manually operated air conditioning system integrates the heater with the function of producing cold and dehumidified air achieved by switching on the compressor and the cooling system.The vehicle climate control system is operated using the four control knobs:
the left-hand knob mechanically controls the hot and cold air mixing (22 positions);
the left middle knob allows the regulation, through an electrical control, of the air ventilation at four different speeds (4 positions) and the engagement of the compressor by pressing the ring nut;
the right middle knob makes it possible to select whether or not to set the "recirculation" function which prevents the intake of new air into the passenger compartment.
the right knob mechanically controls the opening of the flaps that regulate the distribution of air flows (5 positions).
The transmission of the air mixing, air distribution and recirculation commands from the knobs to the climate control casing takes place by means of bowden cables.With the compressor enabled, the on switch does not allow the user to zero the fan speed (turn the knob to zero) to prevent the evaporator from freezing.An LED in the knob allows the compressor status (activated/deactivated) to be signalled.The electronic thermostat is designed to detect the formation of ice on the evaporator allowing the compressor to be disabled to prevent the evaporator from freezing.For further details, See descriptions 5040 AIR CONDITIONING CASING AND COMPONENTS The fan is controlled by a dedicated relay and is protected by a dedicated fuse located in the engine compartment junction unit.
