PROGRAMMABLE HUMIDISTAT
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. 
NOTE: To eliminate any programmed humidistat setting, press the humidistat 
 button. Then press the + 
button until you reach “CO” (continuous on), one level above 55%.

5% below the set humidity level, then will cycle on until the set humidity level is reached again.
