HE220 AND HE260 BY-PASS FLOW-THROUGH HUMIDIFIER

The Automatic Humidity Control with Hum
™
Software requires an initial
adjustment period. Set the frost factor dial on 5 and use the following table to adjust
the frost factor—only one setting at a time—increasing the dial setting if you feel you
need more humidity, or reducing the setting if you see moisture on the inside of your
windows. For more precise humidity adjustment, set the frost factor between dial
settings. Allow two days for the humidity level to subside before making further
adjustments. Once you have tuned in the proper setting, you should never have to
adjust it again. Hum
™
Software 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.
CHECKING YOUR HUMIDIFIER FOR CORRECT
OPERATION
After winter startup or servicing, use the following steps to check your humidifier
operation:
1.
Turn on the humidifier power and water supply.
2.
Turn the humidistat to its highest setting and set the thermostat to 10°F (6°C)
above the room temperature.
3.
Observe that water is flowing out of the drain hose.
NOTE: The furnace blower must be running to activate the humidifier.
4.
Reset the thermostat and humidistat to a comfortable setting for automatic
operation.
