Operating Your Humidifier - Honeywell HE220A Owner's Manual

HE220A,B AND HE260A,B BY-PASS FLOW-THROUGH HUMIDIFIERS

OPERATING YOUR HUMIDIFIER

Your Honeywell HE220A and HE260A humidifiers are
controlled by the H908A Convertible Humidity Control that is
installed either on an interior wall in the living area or on the
return air duct. Choose the humidity control setting using the
combination relative humidity/outdoor temperature setting
scale on your humidity control. Match the dial setting to the
outdoor temperature for optimizing the humidity level while
reducing the moisture condensation on your windows. The
table below can also be used to adjust the humidity control to
the recommended setting.
At Outside
Temperature
-20°F (-29°C)
-10°F (-23°C)
0°F (-18°C)
NOTE: As the outside temperature drops, the recommended humidity control setting is
lowered to accommodate for effects of dew point. These settings should reduce the
accumulation of moisture and ice on your windows and in other areas of your home.
Some indoor activities such as cooking,
showering and clothes drying can cause
excessive levels of humidity and start the
accumulation of moisture on your windows.
NOTE: If this condition persists for more
than a few hours, set the humidity
control to the lowest setting to turn
off the humidifier. If the condition
does not improve, ventilate your
home to remove the moisture.

Software inside your automatic humidity
control is designed to automatically adjust the
humidity level based on indoor temperature
and humidity, inferred or measured outdoor
temperature, and the setting of the frost factor
dial. The frost factor allows for variations in
furnace size, window insulation and average
daily climate temperature.
The Automatic Humidity Control with
HumidiCalc+™ Software requires an initial
adjustment period. Set the frost factor dial on
5 and use the following table to adjust the
frost factor—only one setting at a time—
increasing the dial setting if you feel you need
more humidity, or reducing the setting if you
see moisture on the inside of your windows.
For more precise humidity adjustment, set
the frost factor between dial settings. Allow
two days for the humidity level to subside
before making further adjustments. Once you
have tuned in the proper setting, you should
never have to adjust it again. HumidiCalc+™
Software takes over and makes any future
M12817
adjustments caused by varying outdoor
temperatures, thus reducing moisture build-
up on windows while maintaining the optimal
humidity level.
