automatic climate control

["Stefan Richter" <Stefan13@worldnet.att.net>]

It has gotten rather cool here in Buckingham Pennsylvania over the past 4
or 5 days.  My 95 S6 seems to love the temperature and air quality, it is
running better than ever.  Perhaps some of you can enlighten me on the
climate control system a little.  When I press the AUTO button, no matter
what the outside temperature, (52 F this morning), and no matter what I set
the temperature on the system, the a/c symbol lights up, and you can hear a
relay clicking in the dash, presumably to turn on the a/c on.  I am a
little surprised that the system is not sophisticated enough to recognize
when a/c is not needed, hence automatic climate control.  Is there a
problem with my system or is this simply something I should get used to? 
Please forgive the childish questions, this is my first Audi.
