You already got the 'bad' news that it only circulates house air but..
The good news is that running it 'on' will significantly delay the
start of the AC. Much cheaper to run that fan than the AC. In my
case, when it becomes a bit uncomfortable in the house, putting it
"on" will keep the AC from running for another hour or two if it isn't
too hot outside.

Harry is right. Turning the fan "ON" will circulate the cooler air
that sinks to the lowest level of the house and cool the upper levels
while heating up the lower levels. So, it depends on where the
thermostat is located. In my 4-level split, the thermostat is on the
third level up, and running the fan "ON" cools it down about 2 degrees
while heating up the lower levels, and does delay turning the
compressor on by an hour or two.

You and Harry are clueless. As Noon said, it will raise the humidity
level. Also, trying to pull that cool air from the basement will
reduce the ability of your system to be able to remove the warm air
from a first and second floor. Air will take the path of least
resistance and you will remove no warm air from your upper levels.
You two should really get a clue before you start babbling
