– Passenger compartment heating resistors (depending on the equipment level):
The passenger compartment heating resistors (RCH) are electrical heating devices in the air conditioning unit.
This system is an additional heating system which operates when the engine is cold (when starting).
• ACTUATORS
– Air distribution flap:
This flap enables the air flowing into the passenger compartment to be directed.
– Air mixing flap:
This flap mixes the air in order to meet the temperature requirements of the occupants.
– Recirculation flap:
This flap prevents the entry of exterior air. In this case, the passenger compartment is isolated from the
exterior and air is blown in the passenger compartment in a closed circuit.
These three flaps are controlled by a cable.
• OTHERS
– Passenger compartment blower unit:
The passenger compartment fan assembly is controlled by the Resistive Blower Dimmer Module (MVPR).
