2006 Hyundai Tucson has hot fresh air, is this normal? - used hyundai tucson

If you only have fresh air, no auto temp, warm air through the ventilation slots. Service said it was normal, and the cold air into the engine and start the return (no fresh air), which include many cars and never this problem. I must add that the outside temperature is cold, about 50 degrees
