Do not cut or drill into any air conditioning line or
electrical accessory.
CAUTION
Freezing Water, Flooding or
Static Pressure Hazard.
Can cause water damage to home or permanent
equipment damage.
• The humidifier must be located where the ambient
temperature is above 32°F and below 160°F (0°C
and 71°C).
• Be sure supply plenum static pressure is no
greater than 0.3 in. w.c. and water pressure is no

WIRING THE HUMIDIFIER
CAUTION
Hazardous Voltage.
Can cause personal injury or equipment damage.
• Disconnect the power supply before installing or
servicing.
• On multispeed blower applications, do not wire the
high voltage side of the transformer to the same
power source that services the furnace blower.
Premature transformer burnout may occur.
All wiring must comply with applicable local codes,
ordinances and regulations.
1. Mount the transformer in a convenient location.
2. Connect wires to the 120V side of the transformer.
3. Wire the humidifier solenoid valve, current sensing
relay, or sail switch, humidity control and transformer.
Refer to the humidity control installation instructions for
mounting and wiring information.
M12304
10. Seal the duct connections with duct tape.
NOTE: To avoid sagging and stress on the humidifier,
add support when ducting is longer than
4 ft (120 cm).
68-0191—3
NOTE: Select models of fan centers include humidifier taps
so the current sensing relay or sail switch is not
needed.

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 HE220A and HE260A
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 Honeywell HE220B and
HE260B 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.

OPERATION
The HE220A,B and HE260A,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 a humidifier pad. The
warm dry air from the furnace passes over the humidifier pad
and collects moisture and them 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.
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.
Every 1 to 3 Months
(Depending on Water Quality)
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.
