Whole Home Bypass Humidifier
APPLICATION
This kit contains your new Honeywell HE105 or HE205
Humidifier, H8908 Humidistat and all the accessories
required for installation.
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.
