Dynamic / recirculation air
The special actuator rotates the air intake flap (P) between the two extreme positions: the one if figure A
closes the internal air intake and consequently the electric fan only draws in outside air; the latter is in­
hibited and recirculation air is drawn in if the flap is positioned as illustrated in figure B.

Hot/cold air mixing
The special actuator rotates the flap (M) between the extreme positions (LO) and (HI).
In the (LO) position, the flow of air drawn in by the fan is distributed to the various vents without under­
going any variation in temperature because it is impossible to come into contact with the heater radiator
(R) finned surface.
When the mixture flap is in the limit position (HI) the entire flow of air introduced by the electric fan has
to come into contact with the heater radiator fins with hot air at the maximum possible temperature be­
ing distributed to the various vents.
When the mixture flap is in an intermediate position between the two positions mentioned above, only
part of the air flow introduced by the electric fan comes into contact with the heater fins.
