PLUMBING THE SADDLE VALVE
Hot or cold water, either hard or softened, can be used in the
humidifier.
1. Use the self-piercing saddle valve (included) to tap into
the water supply line at an appropriate location.
IMPORTANT
• The saddle valve is not designed to regulate water
flow. The valve is either open or closed.
• To prevent debris from clogging the solenoid inline
filter, be sure to install the saddle valve handle
pointing toward the ceiling.
NOTE: Lightly clean the copper tubing ends with fine
sandpaper before making any connections.
2. Use 1/4 in. O.D. copper tubing and connect the saddle
valve to the inlet side of the solenoid valve.
CAUTION
Hazardous Voltage.
Can cause personal injury or equipment damage.
Do not use any line connected to an air conditioner.
a. Place the brass compression nut over the copper
tubing.
NOTE: Do not over tighten the compression nut.
Moderate tightness prevents leaking.
b. Slide the brass ferrule over the tubing.
c. Insert the tubing into the solenoid valve fitting and
support the valve while tightening the
compression nut.
3. Connect a 1/2 in. (13 mm) drain tube to the humidifier
drain fitting and run to a suitable drain.
NOTE: Slope the drain tube downward for correct
drainage.
CHECKING THE INSTALLATION
Use the following procedure to check out the humidifier
installation:
1. Open the saddle valve.
2. Set the thermostat setpoint to 10
°
F (6
°
C) above the
room temperature.
NOTE: The furnace blower must be on for the
humidifier to operate.
3. Set the Convertible Humidity Control to a high setting,
or place the H1008A Automatic Humidity Control in the
Test position.
4. Observe the water running out of the drain line to be
sure the humidifier is working.
5. Check for leaks.
6. Reset the thermostat and Convertible Humidity Control
to a comfortable setting, or the Automatic Humidity
Control to the desired frost factor setting, for automatic
operation.
OPERATING THE HUMIDIFIER
The HE225A and HE265A
Humidifiers are controlled by
the Convertible Humidity
Control that 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 the
humidity control dial. Match the
dial setting to the outdoor temperature for optimizing the
humidity level while reducing the moisture condensation on
inside windows. Table 5 can also be used to adjust the
humidity control to the recommended setting.
NOTE: As the outside temperature drops, the
recommended setting is lowered to accommodate
the effects of dewpoint. These settings should
reduce the accumulation of moisture and ice on the
windows and in other areas of the house.
Some indoor activities such as cooking, showering and
clothes drying can cause excessive levels of humidity and
start the accumulation of moisture on the 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.
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 air stream 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 measured
outdoor temperature, and the setting of the frost factor dial.
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 at 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 proper setting has been found, 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.
