BASIC DISPLAYS

GETTING STARTED
1. Unlike most other remote controls you may have
used, the 1999 must be turned on to be used as a
remote control to the humidifier. Likewise, when not
in use, we recommend the remote be turned off to
save the batteries.
2. Pressing the I/O button once will turn the remote and the
humidifier ON and take command of the humidifier.
3. After the remote is turned on, the remote display
will show - - as it calibrates. It will then display
the air temperature (in °F) and the relative
humidity (in %).
4. When the humidifier is under the command of the
1999 remote, the display on the humidifier will
show EC for External Control.
COMMAND ORDER NOTE:
If the humidifier is already on when the remote is turned
on, the remote will take command of the humidifier
controls and revert to the last settings used on the
remote control.
If the humidifier controls are adjusted while it is under
the Remote’s command, the humidifier will take
precedence over the remote, and revert to the last
settings used on the humidifier.

5. Pressing the I/O button a second time will change

ENTERING SETTINGS
Settings are entered into the remote control just as
they are on the humidifier itself.
1. Setting Humidity: Press the center (humidity)
button to increase the humidity. The humidity
setting will increase in 5% increments starting at
25%, progressing up to 65%*, then cycling back to
25%. The humidity setting displays on the lower
segment of the screen. After the setting is entered
and displayed momentarily, the screen will return
to showing the relative humidity.
2. Setting Fan Speed: Press the right hand button
to adjust the fan speed. Each push of the button
increases the speed ranging from F1 to F9, and
then cycles back to F1. The fan setting will
display on the lower segment of the display until
complete, and then revert back to relative
humidity setting.
NOTE: Periodically the remote performs a
frequency check and will be unresponsive to
input. Wait 5 seconds and try your input again.

continuously.
