HE365A
Your Enviracaire Elite™
HE365A Humidifier from
Honeywell is controlled
by the H8908B Convert-
ible Humidity Control.
The convertible humidity
control 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 dial. 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.
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.

insulation. The Automatic Humidity Control with
HumidiCalc+™ requires some initial adjust-
ments when you first install your HE365B. For
maximum humidification, set the H1008 to 10
and run the fan continuously. Check for
condensation on windows after a cold night. If
there is no condensation, leave the setting at
10. If there is condensation, lower the frost
factor dial one setting. Continue to check for
condensation on cold mornings until the correct
humidity setting is reached for your home. Allow
two days between adjustments to determine if
further adjustment is necessary. Once you have
tuned in the proper setting, you should never
have to adjust it again. HumidiCalc+™ takes
over and makes any future adjustments caused
by varying outdoor temperatures, thus reducing
moisture build-up on windows while maintaining
the optimal humidity level.

HE365B
Your Enviracaire
Elite™ HE365B
Humidifier is
controlled by the
Honeywell H1008
Automatic Humidity
Control with
HumidCalc+™. 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
HumidCalc+™ software inside your automatic
humidity control is designed to measure or infer
the outdoor temperature and automatically
adjust the humidity based on the frost factor. The
frost factor is set by the homeowner and allows
for variances in furnace size, window type and
Humidity Level Recommended Setting
Insufficient humidity Increase the frost factor dial by one setting.
Condensation on windows Decrease the frost factor dial by one setting.
