Essick 826 800 Care And Use Manual page 7

Operation:
18) The automatic humidistat will turn the humidifier on when the relative humidity in
your home is below the humidistat setting and will turn off the humidifier when
the relative humidity reaches the humidistat setting. When the humidifier is
running, you will feel cool, invisible, humid air exiting from the outlet grille.
19) When first plugged in, the display will show the current Room Humidity and will
default to 45% set humidity. If there is no water in the reservoir, the red "Refill"
indicator will be lit and the motor will not run. Unplug the humidifier and fill to
the water level specified.
20) When the reservoir has been filled to the "Fill to Here" marking on the
cabinet side wall, connect the power cord. The Refill indicator will not
be lit, and the motor speed can be set to desired LO or HI speed by
pressing the "OFF LO/HI" button. The green Power indicator will be
lit. To change motor speed or to turn OFF, repeatedly press the "OFF
LO/HI" button.
21) If the room humidity is lower than the Set Humidity, the motor will run. If
higher than the Set Humidity, the motor will not run. The desired humidity
level can be changed with the "Set Humidity" button. Press the button
once, and the display will flash. Press the button repeatedly to increase
the Set Humidity in steps of 5% RH. When the desired humidity level is
reached, (between 30 - 90 % RH), release the button. If the button is
released and then held down while flashing, the display will
auto-advance rapidly through the range (30 - 90% RH). To exit the
auto-advance mode, release the button.
22) After the "Set Humidity" button has been inactive for three (3) seconds,
it will exit the Set Mode with the last programmed number remaining on
the display.
CAUTION: Under certain conditions, cold objects in the room, such as
windows and outside walls, may cause moisture to condense. Severe
condensation on window sills and walls may result in water damage.
When these conditions exist, a lower humidistat setting is recommended.
