Setting the electronic humidistat
The electronic humidistat allows you to
set the humidity within a range from
20% to 90%, in 5% increments. The
current room humidity level is displayed
in large numbers, while the desired
humidity level is displayed in smaller
numbers. If the current room humidity
level drops below 20%, the display will
show LO. If it is higher than 90%, HI
will be displayed. Press the ▲ and ▼
buttons to adjust the humidity level. The
humidifier will then turn on automatically
whenever the current room humidity
drops more than 2% below the desired
humidity. Once the desired humidity is
reached, the fan will turn off and the
unit will go into stand-by mode.
