Attic Fan Thermostat/Humidistat 60-120°F
This Dayton thermostat controls attic fans by monitoring both temperature and humidity. It operates on a 120V AC supply and switches up to 10 amps. The bi-metallic spring sensor triggers the fan when conditions exceed the set points. It is designed for residential attic ventilation systems.
Installation and common issues
The unit mounts with standard screws and connects via screw terminals for 120V wiring. Power must be isolated before work begins. A frequent issue is setting the differential too narrow, causing rapid cycling. The 10-degree differential helps prevent this. Ensure the sensor is exposed to attic air, not insulated.
Who this suits and who should look elsewhere
This switch suits homeowners needing automatic attic cooling within a 60 to 120°F range. It is not for buyers who want smart-home integration or remote monitoring. It does not support heating systems or multi-stage equipment. Installers requiring a different voltage or amperage rating should select another model.

Questions about this item
How do I verify the thermostat is cycling the attic fan correctly after installation?
Set the dial between 60 and 120 degrees F and watch for the fan to start when the attic temperature reaches that point; the bi-metallic spring sensor and close-on-rise action will open the circuit again once the temperature drops about 10 degrees F.
What comes with the thermostat and what must I supply separately?
The unit includes the thermostat/humidistat housing with two SPST switches rated for 10 A at 120 V AC; you must provide mounting hardware, wiring, and a compatible attic fan.
Which control range should I choose for my attic ventilation needs?
This model offers a single adjustable range of 60 to 120 degrees F with a fixed 10-degree differential, so select it if your desired fan-on temperature falls within that span.
