General Aire GFX4 Automatic Digital Humidistat

The General Aire GFX4 automatic digital humidistat controls the furnace blower motor to provide consistent humidity levels in your home. With the included outdoor sensor, the humidistat will automatically adjust by reading outdoor temperatures -- or you can adjust the humidity levels manually without the sensor. This humidistat can be mounted on your wall or directly on the duct to accurately display humidity levels on its easy-to-read LCD. It features an extended humidity range from 10 to 75 percent.
