HEATER - Description

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 control the following: one knob electrically controls the air ventilation at four differente speeds, the other mechanically controls the function of air recirculation in the interior compartment, via a flexible cable.

The different fan speeds are controlled by a resistive divider.

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

The whole system is protected by specific fuses, housed in the junctions 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.
