Setting the fan speed
Turn the fan speed knob to the
desired setting. To increase the
humidity in a room more quickly, set
the knob to HI. For normal operation,
set the knob to MED. For quiet,
nighttime operation or for a more
gradual increase, set the knob to
Quietmist™ .
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 s and t buttons to adjust the
humidity level. The humidifier will then
turn on automatically whenever the cur-
rent 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.

The power on indicator will light to
indicate that the humidifier is on.
