The Humidistat mode automatically turns ON a ventilation fan for a set period until the relative humidity (RH) is greater than or equal to the selected humidistat setting (35%, 50%, 65% or 80%). The fan will run for the time you set and when that time expires, the fan will turn OFF for the remainder of the hour. (Ex: The fan will run 20 minutes every hour until the relative humidity level is less than 50%.)This feature may be used in areas requiring periodic ventilation on a continuous basis such as basements, laundry rooms and other damp rooms in the home.
