Yet another "newbie" question....
My ducted combo hvac system has a thermostat that has a "hi", "low" and "auto" fan setting. The fan seems to be part of the rooftop AC unit and I am assuming that the furnace has its own blower (since it is fairly quiet when the heat is on).
My main question is that when putting the fan in "auto", the fan is actually "off". I am a bit confused as to why the setting says "auto" instead of simply "off".
I moved into this unit before I had a chance to "study up" on living in an RV and I am encountering a bit of a learning curve.
Thanks in advance for any help.
