OPERATION
Controlling Your Humidity Settings
Your H8908 Humidistat (or other humidity control)
controls your humidifier.
• Choose the humidity control setting using the
combination of relative humidity/outdoor temperature
setting scale on your humidity control dial.
• Match the dial setting to the outdoor temperature to
optimize the humidity level while reducing the moisture
condensation on your windows. See Table 2 on page 6
to adjust the humidity control to the recommended
setting.
NOTE:
As the outside temperature drops, a lower humid-
ity setting is recommended to accommodate
dewpoint effects. These settings should reduce
the accumulation of moisture and ice on windows
and other areas of the home.
• Adjust the humidity control setting to adjust for indoor
activities such as cooking, showering and clothes
drying, which can cause excessive levels of humidity
that can accumulate moisture on your windows.
NOTE:
If these activities persist for more than a few
hours, set the humidity control to the lowest set-
ting to turn off the humidifier. If the condition
does not improve, ventilate your home to remove
the moisture.
Table 2.
MAINTAINING YOUR
HUMIDIFIER
A regular maintenance program prolongs the life of your
humidifier and makes your home more comfortable. The
frequency of cleaning depends on the condition of your
water.
You can use either hard or soft water in your humidifier,
but hard water mineral deposits are more difficult to clean
than soft water deposits.
IMPORTANT
Never oil any part of the humidifier.
End of Humidification Season
• Clean the humidifier and shut it off at the end of the
heating season.
• Turn the water off at the saddle valve or T-valve fitting
by turning the handle to the right (clockwise) until the
water stops flowing and/or there is resistance.
• Un-power the humidifier.
• Turn the damper blade to the "closed" position.
Replacement Humidifier Pads
Honeywell recommends replacing the humidifier pad on
an annual basis. However, if your home has hard water, the
pad may need to be replaced more frequently because of
the buildup of minerals diminishing its ability to operate
normally. If there is access to a water softener, it is
recommended to use softened water.
