SETTING THE DESIRED HUMIDITY LEVEL
The control will allow you to set
the desired humidity level in your
space and can be used to turn
dehumidification on or off.
Begin by pressing the ON button
and ON will be displayed on the
LCD Screen (see LCD display in
FIGURE 1). Use the arrow buttons
to set the control to the desired
humidity level.
Raise the setting if you prefer
the air to be less dry; this will
reduce the amount of time that
the dehumidifier runs.
Lower the setting if you prefer
the air to be more dry; this will
increase the amount of time
that the dehumidifier runs.

CONTROL LIMITS
The control limits are used to make sure the dehumidifier does not run when conditions are
outside of the operating limits. Dehumidifiers are not as effective when conditions are outside
of the operating limits. For example, the dehumidifier will not remove much moisture when
conditions are cool and dry. Control limits allow the dehumidifier to work efficiently within the
operating range and turn off when conditions are outside of these limits.
Dew Point Lower Limit 40°F Temperature High Limit 99°F
