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. M13608 At Outside Temperature -20°F (-29°C) -10°F (-23°C) 0°F (-18°C) Recommended Setting Low Low Med At Outside Temperature +10°F (-12°C) +20°F (-7°C) Above 20° (-7°C) Recommended Setting Med High High 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. 69-1110EF-02 2
