DIGITAL DISPLAY
Press the power button once to turn the unit on. Initially there is a slight delay while the
electronics calibrate. Two bars (
- -) appear during this time. Once calibration is
complete a ROOM humidity reading between 20%
- 95% will be displayed. A flashing
20 display indicates that the room humidity is less than 20%.
NOTE:
The default settings at initial startup are (Ultra Quiet) F1 fan speed and
65% SET humidity.
After desired settings are selected by the user, they remain
as long as the unit remains plugged in and there is no power interruption. If the
unit is unplugged the original default settings are employed.
ABOUT
HUMIDITY
Where you set your desired
humidity levels depends on your personal comfort
level, outside temperature and inside temperature. A starting set point of 30%
-
40% ROOM
humidity is recommended but there may be conditions that require a
different setting
.
NOTE
: Recent CDC tests show that the chances of flu transmission are greatly
reduced at levels of 43% humidity.
You may wish to purchase a hygrometer* to measure the humidity level in your
home. The following is a chart of recommended humidity settings

*Model 1990 digital hygrometer is available for purchase by calling 1-800-547-3888.
NOTE:
External hygrometer readings and humidistat readings may differ.
Humidity levels can vary significantly even in one room.
HUMIDITY CONTROL
NOTE: Allow 10 to 15 minutes for the
humidistat to adjust to the room when
setting up the unit for the first time.
The MA1201 has an automatic humidistat
located on the cord that measures the
relative humidity in the room. When the
selected humidity level drops 3% below
the relative humidity, the humidifier cycles on and off as required to maintain the
selected
setting allows you to adjust the humidity to suit your needs. The
readout displays both actual (ROOM) and desired (SET) humidity percentage
(%) settings when humidity control button is pressed. The ROOM readout has a
range of 20% to 95%. If the room humidi
ty level is equal to or less than 20% the
display will show a flashing
20.
IMPORTANT: Water
damage may result if
condensation starts to form
on windows or walls.
Humidity SET point should
be lowered until
condensation no longer
forms. We recommend
room humidity levels do not
exceed 50%.
