OPERATING YOUR HUMIDIFIER
Humidifiers are controlled by the Convertible
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 moisture condensation on your
windows. The table below can also be used to
adjust humidity control to the recommended setting.
NOTE: As outside temperature drops, the recommended humidity control setting is
lowered to adjust for effects of dewpoint. These settings should reduce accu-
mulation of moisture and ice on your windows and 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.
HOW YOUR HUMIDIFIER WORKS
Your 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 the
antimicrobial 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.
