What Does Humidistat Mean?

A humidistat or hygrostat is an electronic device analogous to a thermostat but which responds to relative humidity, not temperature. Humidistats are used in a number of devices including dehumidifiers, humidifiers, and microwave ovens.

What is the purpose of a humidistat?

A humidistat (sometimes called a humidistat control) is a device that works with a home's heating and cooling system to automatically adjust the amount of moisture in the air to maintain a specific humidity level throughout the home.

What should your humidistat be set at?

So to be safe, we recommend setting your humidistat's relative humidity (RH) to 58 percent and setting your thermostat temperature between 77 and 80 degrees Fahrenheit. These settings will not maintain your selected temperature indoors but will maintain 58 percent humidity.
