Attic fan thermostat

I'm a relatively new homeowner, we've been in our house slightly over 1 year. Our 2nd floor has always been too warm in the summer. We knew we had an attic fan and went up to investigate. It appears to be working properly and the thermostat was set at 110. We lowered the thermostat to 100 and it has made a huge difference. The thermostat change made the 2nd floor much more comfortable.

We don't want the attic fan to be continuously running. Are there recommendations as to what the thermostat for an attic fan should be set at and does it vary by the season? Ours is hardwired, so we don't have the luxury of flipping a switch off when we don't want it to run.

Thanks for any help you can provide!

Test it.

90 to 100 is OK. A lower setting only means the fan runs more and keeps the attic temperature down. Trying a lower setting might improve the upper floor more. It is a cheap experiment. Then decide for yourself what the best setting is.
