It may need to run all day. It's July, and the hottest average month is still ahead of us.
I've worked to many times in attics. They get hot Mister.
Anyway, mine was set for 90. When I had it. I took it out and installed two more 12" attic deck vents. Works just as good and not using electricity.

I like to set them at 90. You may not have very good air flow into the attic or the fan may be undersized. Make sure you have a big enough fan for the square footage.
Assuming the ambient temperature drops below 120 at night after a few hours the fan should be able to exchange all the hot air in the attic with cooler outside air.

120 sounds good, But if it is set lower, at night you can get the temperature lower in the attic.
Are the controls easy to get to?
I would run it more with a lower setting at a lower speed during the day & increase the speed in the early evening. The attic temperature should drop to less than the setting so it won't run all night long.

If your fan is set at 120 and still runs most of the day I would consider adding more vents in the soffit or a couple vents on the roof. It is important for the life of your roof to vent. Roof vents can be purchased from Lowes/Home Depot for as little as $10, and installed in under an hour. But to answer your question I would set the fan at no more than 100. Mine are set at 90

you will possibly not in simple terms like the respond yet there are issues that must be performed first on the grounds which you're actually not the unique proprietor. you will ought to make certain what proportion cubic ft of air the fan will pass, perhaps be on the nameplate. you will additionally ought to understand how lots "loose area " you ought to pass the air around the attic. If the fan strikes greater air than it could get it will strengthen the amp draw. I had one in a house lengthy in the past. you may deploy a line voltage thermostat interior the attic it fairly is used for air con, while the temp. rises the fan runs and while the temp drops the fan stops. you need to use a low voltage thermostat yet you may ought to additionally deploy a relay and a transformer to deliver interior the fan, which may be greater wiring to make the relationship. a reliable electrician must be waiting to try this, not all electricians are into wiring controls.

The one I had was set at 120 also. It ran most of the time on a sunny summer day. If it is not to your liking then raise or lower the temp to suit your preferences. good luck.

The dial isn't for temperature. It's for time. And running an attic fan with the A/C on isn't very cost effective. You are pulling cool air into the attic.

It sounds correct and normal to me. It should shut off at night when things cool off.
