A:Answer The default humidistat setting is CO (continuous on). The programmable humidistat can be set in 5% increments, from 35% to 55% humidity. To program the humidity level, press the humidistat button. Then press the + or – button. The humidity level will increase/decrease by 5% every time the + or – button is pressed and will show on the display screen. Keep pressing the + or – button until the desired humidity setting is reached. The display will show the set humidity level for 5 seconds, then default back to display the mist output level.
