Operating the Controls
(cont’d.)
Speed Button
This humidifier is equipped with a
3-speed fan control. Each push of the
speed button advances the mode through
the settings of
HIGH, MEDIUM, ULTRA
QUIET, and AUTO.
The selected setting
is displayed on the digital readout. The
higher the setting, the faster water is
evaporated and released into the air.
ULTRA QUIET
is the quietest setting and
is provided for conditions that do not
require a rapid evaporation rate.
How Auto Control Works
The
AUTO
setting allows the humidifier to
manage it’s speed range to maintain your
desired humidity setting. It will
automatically cycle to the most efficient
speed to achieve the desired humidity.
Here is how the fan will operate:
•
HIGH
speed if room humidity is 10% or
greater RH (Relative Humidity) below
the
SET
point.
•
MEDIUM
speed if room humidity is
10 - 5% RH below the
SET
point.
•
ULTRA QUIET
speed if room humidity
is 5% or less RH below the
SET
point.
Humidity Control
These buttons allow you to adjust the
humidity to suit your needs. This
humidifier will automatically cycle on and
off as required to maintain the selected
setting. Press the humidity buttons
to cycle the
SET
humidity readout in 5%
increments between 25% and 65%.RH
Once you have set the desired humidity,
after 5 seconds the readout will change
to the actual room humidity.
NOTE:
When the
ROOM
humidity is
displayed, pressing the set humidity
buttons once will display the current
SET
point. To increase or decrease the current
SET
point, press either the
“+”
or
“-”
button until the desired
SET
point is
reached.
A
SET
point of 65% RH operates the
humidifier continuously regardless of the
ROOM
reading. The humidistat that
senses the readings is located on the
power cord. Insure that it is free from
obstruction.

If the room humidity is not increasing at
the current fan speed during a 15 minute
period, the fan speed increases to the
next higher speed until the humidity
SET
point is reached.
NOTE:
The humidifier may run on
HIGH
for an extended period of time if the
actual room humidity is extremely low.
