After reading the manual quite a bit, it appears that if I want to turn off ALL the heating/AC functions I just turn the fan **** to the "O" When I do this it still blows (maybe in bypass) until I turn the temp control **** to the recirculation setting (far left), then there is no airflow at all. Is this normal? Or is something not closing right.

Thanks.
