ON/OFF BUTTON
(fig. 116)
Inside air re-circulartion is controlled ac-
cording to three operating logics:
- automatic control, indicated by the turn-
ing on of the right led on the button;
- forced engagement (inside air re-circula-
tion always on), indicated by the turning on
of the left led on the button (and by the right
led going off at the same time);
- forced switching off (inside air re-circula-
tion always off with air inlet from outside),
indicated by the turning off of both leds.
These operating conditions are obtained
pressing in sequence the inside air re-circu-
lation button (8) v .
When inside air re-circulation is controlled
automatically by the system, the right led
on the air re-circulation button (8) v
stays on all the time and the left led shows
the air re-circulation condition:
on = air re-circulation operating;
off = air re-circulation off.
If inside air re-circulation has been turned
on or off manually, the led on button (13)
turns off.

the windows misting inside, espe-
cially if the climate control system
is off.
