Your Enviracaire Elite™ HE225A and HE265A 

Humidifiers from Honeywell are controlled by the 

H8908B Convertible Humidity Control. The 

convertible humidity control is installed either on an 

interior wall in the living area, or on the return air duct. 

Choose the humidity control setting using the 

combination relative humidity/outdoor temperature 

setting scale on your humidity control dial. Match the 

dial setting to the outdoor temperature for optimizing 

the humidity level while reducing moisture 

condensation on your windows. The table below can 

also be used to adjust humidity control to the 

recommended setting.

NOTE: As outside temperature drops, the recommended humidity control setting is 

lowered to adjust for effects of dewpoint. These settings should reduce accu-

mulation of moisture and ice on your windows and other areas of your home.

Some indoor activities such as cooking, showering and clothes drying can cause 

excessive levels of humidity and start the accumulation of moisture on your windows. 

NOTE: If this condition persists for more than a few hours, set the humidity control to 

the lowest setting to turn off the humidifier. If the condition does not improve, 

ventilate your home to remove the moisture.

Your Enviracaire Elite™ HE225B and HE265B 

Humidifiers are controlled by the Honeywell H1008 

Automatic Humidity Control with HumidiCalc+™. The 

automatic humidity control is mounted in the return air 

duct where it can be exposed to the air stream of the 

return air.
