When the temperature adjustment switch on the control
panel is pressed to set a specific temperature, the auto
amplifier performs computation based on various input
sensor signals, and obtains the overall signal T. Further,
it compares the predetermined air mix door opening
and P.B .R . signal with respect to this overall signal T,
and determines whether the air mix door opening is
appropriate.
If the air mix door opening is not appropriate, the air mix
door moves toward the heat or cool side so that the
appropriate door opening can be obtained .
