When in AUTO and weather conditions require
cooling, the EATC will use outside air or
recirculated air, depending on the temperature
that is selected.
If unusual conditions exist (i.e., window fogging,
etc.), the six manual override buttons allow you
to select special air discharge locations. The fan
speed button allows you to adjust the fan speed
to suit your needs.
