Description general (page 2 of 2)

The flap (1) is controlled via a linkage by an electric motor fastened on the outside of the duct.

On the left-hand side of the heater-distributor unit, three bowden cables are connected which suitably direct the lower air distribution port (3) the upper port (2) and the mixing port (5) and control the position of the cock fitted on the inlet duct of the heater radiator (4).

Control panel

The control panel comprises three knobs and two pushbuttons:

• the lefthand knob (1) controls the flow of air:
  • OFF: air inlet shut off
  • 0: inlet of outside air without fan (dynamic air) (NOTE: if the compressor is engaged, the fan is operated at the first speed).
  • from 1 to 4: a switch is operated which turns on the fan through a four-speed regulator.
• the centre knob (2) controls the mixing port between warm air (red) and cold air (blue); if it is turned completely to the left, it closes a special cock and shuts off the heater;

• the righthand knob (3) adjusts the air flow distribution acting on the distribution ports sending air to the passenger compartment in the directions shown on the ideograms;
• the special pushbutton (4) operates the "recirculation" function;
• Pushbutton (5) turns on the cooling system which produces cold and dehumidified air.
