Operating Your Humidifier - Honeywell Enviracaire Elite HE225A Owner's Manual

HE225A,B AND HE265A,B BY-PASS FLOW-THROUGH HUMIDIFIERS

OPERATING YOUR HUMIDIFIER

Your Enviracaire Elite™ HE225A and HE265A Humidifi-
ers from Honeywell are controlled by the H8908B Convert-
ible 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. The automatic humidity control is
mounted in the return air duct where it can
be exposed to the air stream of the return
air. The HumidiCalc+ 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

adjustments. Once you have tuned in the
