A dehumidistat is a device that reads the moisture of the air in your home. You can set dehumidistats to a humidity level that’s within the optimal humidity range for your health and comfort (between 40 and 65%). If the humidity levels rise above the level you’ve set, the dehumidistat will automatically turn on an exhaust device, such as a bathroom fan.
In general, the humidistat should be set according to the outdoor air temperature. When it’s colder outside, you’ll want to set your humidity level lower (but within the 40-60% range).
