HOW YOUR
HUMIDIFIER WORKS
Your Honeywell humidifier uses the principle
that hot water creates moist air and as the
moist air circulates, the relative humidity rises.
Your humidity control monitors the relative
humidity and activates the humidifier
accordingly.
When the humidity control calls for humidity,
the humidifier underwater heater starts
heating the water in the humidifier reservoir.
When the water is warm enough, the
humidifier activates a relay that turns on the
furnace fan. The warm dry air from the
furnace picks up the moist air and circulates it
through the home. The fan continues to
circulate the air until the water cools down
and then turns off the fan.
Humidity Level
Recommended Adjustment
Insufficient humidity
Increase the frost factor dial by one setting.
Condensation on windows
Decrease the frost factor dial by one setting.
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.
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.
