How Your Humidifier Works; Maintaining Your Humidifier - Honeywell HE250A1005 Owner's Manual

HE225A,B AND HE265A,B BY-PASS FLOW-THROUGH HUMIDIFIERS WITH AGION
The HumidCalc+™ software inside your automatic humidity control is designed to
measure or infer outdoor temperature and automatically adjust the humidity based on
the frost factor setting that the homeowner sets to allow for variances in furnace size,
window type and insulation.
The Automatic Humidity Control with HumidiCalc+™ requires an initial adjustment
period. For maximum humidification, set the H1008 to 10 and run the fan continuously.
Check for condensation on windows after a cold night. If there is no condensation,
leave the setting at 10. If there is condensation, lower the frost factor dial one setting.
Continue to check for condensation on cold mornings until the correct humidity setting
is reached for your home. Allow two days between adjustments to determine if further
adjustment is necessary. Once you have tuned in the proper setting, you should never
have to adjust it again. HumidiCalc+™ takes over and makes any future adjustments
caused by varying outdoor temperatures, thus reducing moisture build-up on windows
while maintaining the optimal humidity level.

HOW YOUR HUMIDIFIER WORKS

Your Enviracaire Elite™ 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
AgION™ 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.
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 cleaner, more comfortable environment that is
also energy efficient.

MAINTAINING YOUR HUMIDIFIER

A regular maintenance program prolongs the life of your humidifier and provides a
more comfortable home. Frequency of cleaning depends on the condition of your
water. You can use either hard or soft water in your humidifier, but hard water mineral
deposits are more difficult to clean than soft water deposits. For optimum performance,
Honeywell recommends replacing the AgION™ antimicrobial pad once a year. Use the
following procedure to clean your Honeywell humidifier.
Recommended Setting
Increase the frost factor dial by one setting.
Decrease the frost factor dial by one setting.
