HE120 BY-PASS DRUM HUMIDIFIER

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 disburses 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 through your home.
Humidified air feels warmer and more comfortable so you may be able to lower your
thermostat heating setpoint and save money on your heating fuel bills. The end result
is that your humidifier gives you a comfortable environment that is also energy
efficient.
OPERATING YOUR HUMIDIFIER
Your HE120 Honeywell humidifier is controlled by
the Humidity Control that is installed either on the
return air duct or on an interior wall in your living
area. 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.
NOTE: As the outside temperature drops, the recommended humidity control setting
is lowered to accommodate for the effects of dewpoint. 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.
