HE225A,B AND HE265A,B BYPASS FLOW-THROUGH HUMIDIFIERS
The Enviracaire Elite
HE225B and HE265B
Humidifiers are controlled
by the Honeywell H1008A
Automatic Humidity Control
with HumidiCalc+™
Software. The automatic
humidity control is mounted
in the return air duct where
it can be exposed to the
airstream of the return air.
The HumidiCalc+™ Software inside the automatic humidity
control is designed to automatically adjust the humidity level
based on indoor temperature and humidity, inferred or

OPERATION

The HE225A,B and HE265A,B Humidifiers use 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.
The humidity control monitors the relative humidity and
activates the humidifier accordingly. The humidifier has a
water supply that disburses water over an antimicrobial
humidifier pad. The warm dry air from the furnace passes over
the humidifier pad, collects moisture and then circulates it
through the house.
Humidified air feels warmer and more comfortable so the
homeowner may be able to lower the thermostat heating
setpoint and save money on heating fuel bills. The end result
is that the humidifier gives the homeowner a comfortable
environment that is also energy efficient.

measured outdoor temperature and the frost factor dial
setting. The frost factor allows for variations in furnace size,
window insulation and average daily climate temperature.
The Automatic Humidity Control with HumidiCalc+™ Software
requires an initial adjustment period. Set the frost factor dial
on 5 and use Table 6 to adjust the frost factor —only one
setting a time—increasing the dial setting for more humidity or
reducing the setting if moisture develops on inside 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 the correct
M12817
setting is determined, no further adjustment is needed.
HumidiCalc+™ 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.

MAINTENANCE

A regular maintenance program prolongs the life of the
humidifier and provides a more comfortable environment.
Either hard or soft water can be used in the humidifier.
Frequency of cleaning depends on the condition of the water.
CAUTION
Voltage Hazard.
Can cause electrical shock and equipment
damage.
Disconnect power supply before installing or servicing.
IMPORTANT
Never oil any part of the humidifier.
