When the AUTO switch on the control panel is pressed,
the switch signal is sent into the auto amplifier. The auto
amplifier microcomputer computes the outlet air tem-
perature based on the evaporator sensor signal and air
mix door opening signal (computed from the tempera-
ture setting signal and various sensor signals) . It also
compares the computed result with the outlet port
selection criterion, and drives the mode door actuating
motor to select the air outlet from among the VENT,
BI-LEVEL and HEAT modes.
