That's not "the way it works."

Odds are the thermostat that measures inside temp has failed or
the hose the feeds it has come undone (sucks air past it and back
into the system) used to be on the dash, just to the right of the
A/C control. Look for some small slots in the dash. If yours is a
split system there are probably two sensors. One failing to hot
could cause this symptom. (at least it does in buildings that have
multiple climate areas) I'm not familiar with your system but
they all work about the same way.
