system may switch to recirculated air mode automatically. This may also
reduce fuel consumption.
●
It is possible to switch to outside air mode at any time by pressing
●
Engine speed and compressor operation controlled to restrict heating/cool-
ing capacity
●
Fan speed restricted when automatic mode is selected
