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.
