I - FOREWORD
The automatic climate control system allows the user to control the operation of
the air conditioning-heating system automatically, by adjusting:
• the air flow (blower motor),
• the air temperature (mixing),
• the distribution of air in the passenger compartment (distribution),
• the air inlet (recycling),
• the air conditioning function.
The desired temperature is obtained by setting the mixing flap, controlled by a
stepper motor, to the correct position.
The heating is provided by a heater matrix in the engine coolant circuit.
The cold air is produced by a traditional cooling system through an evaporator.
The air flow is provided by a blower motor.
The distribution and air inlet are adjusted by flaps controlled by stepper motors.
The control panel also includes the control for the heated rear screen (this is totally
independent to the other air conditioning functions).
