OPERATION
How Your Humidifier Works
Your Honeywell humidifier uses the principle that vapor
(evaporated water) is created when warm air blows over
a water-soaked area. As the vapor circulates, the relative
humidity rises.
Your humidity control monitors the relative humidity and
activates the humidifier accordingly. The humidifier has a
water supply that dispenses water evenly over a
humidifier pad. The warm dry air, from the furnace,
passes over the humidifier pad and picks up the moist air
to circulate it throughout your home.
Humidified air feels warmer and more comfortable so you
may be able to lower your thermostat heating setpoint,
which saves money on your heating fuel bills. The end
result is that your humidifier gives you a comfortable
environment that is also energy efficient.
Controlling Your Humidity Settings
Your H8908 Humidistat 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
to adjust the humidity control to the recommended
setting.
NOTE: As the outside temperature drops, a lower
humidity setting is recommended to accommo-
date 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.
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.
Use the following procedure to clean your Honeywell
humidifier.
WARNING
