humidity control to the recommended setting.
2. Use 1/4 in. O.D. copper tubing and connect the saddle
valve to the inlet side of the solenoid valve.
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.
CAUTION
Hazardous Voltage.
Can cause personal injury or equipment damage.
Do not use any line connected to an air conditioner.
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.
a. Place the brass compression nut over the copper
tubing.
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.
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.

inside the automatic humidity control
CHECKING THE INSTALLATION
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.
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.
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.
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.

OPERATION
(Depending on Water Quality)
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.
Use the following procedure to clean the humidifier:
1. Disconnect the power and turn off the humidifier water
supply.
2. Remove the humidifier cover. See Fig. 5.
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 and collects moisture and them
circulates it through the house.
WATER
FEED NOZZLE
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.

to restart the humidifier.
IMPORTANT
To maintain the antimicrobial properties of the
humidifier, use only a Honeywell HC22E or HC26E
Antimicrobial Pad. See Table 8 List of Replacement
Parts for appropriate pad. Be sure the marked side
of the antimicrobial humidifier pad is facing up for
proper performance.
CHECKOUT PROCEDURE
After winter startup or servicing, use the following procedure
to check the humidifier operation:
15. Snap the water nozzle back on the tray.
16. Reattach the tray to the frame.
17. Place the humidifier pad assembly in the humidifier
housing and press until the assembly is completely
seated. Be careful not to pinch or kink the water feed
tube.
1. Turn on the humidifier power and water supply.
2. Turn the Convertible Humidity Control to the highest
setting, or place the H1008A Automatic Humidity
Control in the Test position and set the thermostat to
10°F (6°C) above the room temperature.
3. Observe that water is flowing out of the drain hose.
18. Replace the humidifier cover.
19. Verify the humidifier operation by following the steps in
the Checkout Procedure section.
NOTE: The furnace blower must be on for the
humidifier to operate.
4. Reset the thermostat and Convertible Humidity Control
to a comfortable setting, or the H1008AAutomatic
Humidity Control to the desired frost factor setting, for
automatic operation.
End of Humidification Season
At the end of the heating season, follow steps 1 through 18
from the Every 1 To 3 Months section to clean the humidifier
and shut if off.
