The system automatically switches from air
recirculation to fresh air:
• after 30 minutes if the outside temperature is above
about 40 ° F (5 ° C),
• after 5 minutes if the outside temperature is below
about 40 ° F (5 ° C),
• after 5 minutes if economy mode AC OFF is selected.
The system switches automatically to air recirculation at
high outside temperatures. A quantity of outside air is
added after a maximum of 30 minutes.
Important!
If the windows should fog up from the inside, switch
from recirculated air back to fresh air.
