hazardous condition.
INTRODUCTION
Please read this manual completely. It is important that you understand how TrueSTEAM works, and how to
safely perform the required maintenance procedures. Read and understand all safety-related labels found on
and posted near the TrueSTEAM humidifier. These labels provide additional instructions and important
safety information.
Safety Definitions
These safety terms identify information you must read.
CAUTION: Indicates a hazardous situation which, if not avoided, could cause bodily injury or
property damage.
WARNING: Indicates a hazardous situation which, if not avoided, could result in death or serious injury.
Safety Precautions
Make sure you read and understand the following safety hazards before installing, using, or working
with the TrueSTEAM humidifier:
Do not direct the steam nozzle at people.•
Water inside tank can be very hot. Read the warning label on TrueSTEAM and make sure you •
understand the hazards of scalding hot water in the tank.
Scalding danger from draining water. When the water tank empties, draining water can be hot enough •
to cause injury. Make sure you know where the water exits the drain hose. Be certain hot water will not
pose a hazard to people or pets.
WARNING: Electrocution Hazard.
TrueSTEAM uses 120 volts AC, which can cause death or serious injury. Take precautions when servicing
TrueSTEAM or when removing the water tank or cover. If in doubt, unplug TrueSTEAM and disconnect
HVAC equipment power before servicing.
CAUTION: Heavy Equipment and Water Hazard.
Improper installation or misuse can cause death, blindness, and water damage to home, and heating

TrueSTEAM Humidification System 69-2286EFS—03
Welcome!
Congratulations on your new humidifier.
The Honeywell TrueSTEAM humidification system provides the high performance and efficiency of steam, with
easier maintenance than traditional humidifiers.
We are sure TrueSTEAM will be a welcome addition to your home.
How is TrueSTEAM different from other humidifiers?•
- The steam goes directly into your hot air supply duct, rather than evaporating from a wet pad, which
requires furnace temperature to produce humidity efficiently.
- TrueSTEAM delivers humidity independent of your furnace. This allows you to achieve ideal humidity levels
in your home, year-round.
- TrueSTEAM wastes less water than flow-through humidifiers.
- TrueSTEAM operates automatically, just like a thermostat, to keep your home’s humidity at the desired level.
- TrueSTEAM is easy to maintain. Just clean the tank as instructed. The tank is easily accessible and does not
require tools to remove it.
What safety features does TrueSTEAM have?•
- An interlock switch located inside the water tank shuts off 120 VAC power to TrueSTEAM when the tank
is removed.
- Three sets of sensors constantly monitor water level in the tank. The sensors prevent the tank from being
over-filled and from running dry.
INTRODUCTION
How should I get started?• Your TrueSTEAM must be installed by an HVAC Professional Installer. If the
TrueSTEAM has just been installed, it should either be running and humidifying your home, or waiting for a
humidity call from the humidity control provided.
Once TrueSTEAM is up and running, all you have to do is use the humidity control to change the humidity to
your desired comfort.
Please read this manual completely for tips on getting the most out of your TrueSTEAM.
Read your humidity control manual and make sure you know how to operate your system.
If you have questions, now or later, please ask your Installer or call Honeywell Customer Care
at 1-800-468-1502.

How does TrueSTEAM work?
INTRODUCTION
1

2
1. A call for humidity comes from the humidity control
provided with TrueSTEAM. The humidity control is
connected to TrueSTEAM, either with wires or by
wireless connection.
2. The heating element coil heats water in the tank to
the boiling point.
3. The resulting steam flows out of TrueSTEAM into
the hot air supply duct of your HVAC system. If
remote mounting is used, the steam flows through
an insulated steam hose from TrueSTEAM to your
supply duct.
4. Air flow from your furnace fan carries the moisture
throughout your home. Your furnace may or
may not be heating the air, depending on your
thermostat setting and TrueSTEAM configuration.
5. When humidity in your home reaches the setpoint,
the humidity call ends and TrueSTEAM stops
producing steam. The furnace fan may continue
to run until humidity in the duct is completely
distributed to your home.
6. Sensors monitor water level in the tank. The built-in
solenoid valve opens and closes to automatically
refill the tank, as needed. During long periods of
inactivity, the tank will drain completely to prevent
water stagnating. The tank will automatically refill
when there is demand for humidity.

M29668
Which TrueSTEAM model do I have?
TrueSTEAM is available in three sizes, each with a different humidifying capacity:
HM506 Delivers up to 6 gallons of water each day into your home. This is generally suitable for homes
4,000 to 14,400 cubic feet in size.
HM509 Delivers up to 9 gallons of water each day into your home. It is generally suitable for homes
8,000 to 18,400 cubic feet in size.
HM512 Delivers up to 12 gallons of water each day into your home. This model is generally suitable for
homes 12,000 to 24,000 cubic feet in size.
The proper model for your home depends on many factors. Size of the area to be humidified, ceiling height,
window and insulation type, as well as your geographic area, all affect how much humidity your
home needs.
Some activities in your home may create heavier loads for TrueSTEAM. Vented fireplaces, high exhaust from
fans, or driers can reduce humidity in your home and make TrueSTEAM work harder.
TrueSTEAM
YOUR NEW
Your Professional Installer or salesperson will have considered these and other factors when choosing the best
TrueSTEAM model for your unique situation.

Which humidity control do I have?
TrueSTEAM comes with a humidity control. Your humidity control will either be included in your home thermostat
(RedLINK Prestige or VisionPRO IAQ), or it will be a separate device (TrueIAQ or H8908). You will use the
humidity control to set the desired humidity level for your home, and to turn TrueSTEAM on and off.

How is my TrueSTEAM installed?
Your HVAC Professional Installer will install TrueSTEAM in a proper location in your home. The best location
depends on your furnace type and configuration, and how your living space is arranged around the furnace
ducts. Your TrueSTEAM will be either duct mounted or remote mounted.
Duct mounting. TrueSTEAM is installed directly onto
the supply (hot) air duct of your furnace. The steam
nozzle sends steam directly from TrueSTEAM into the
duct for distribution through your home.
TrueSTEAM
YOUR NEW
TrueSTEAM Humidification System 69-2286EFS—03
Remote mounting. TrueSTEAM is installed some
distance away from your furnace supply duct. An
insulated hose carries steam from TrueSTEAM to a
suitable location on the supply duct.
Remote mounting is usually done when a suitable
mounting location can not be found on your
furnace duct.

home’s cold water pipe. Your Professional Installer
may have used the saddle valve that came with
TrueSTEAM, or may have chosen a different type
of connection. This connection must include
a shutoff valve for you to turn off water flow to
TrueSTEAM, if necessary.
IMPORTANT: TrueSTEAM requires cold water.
Do not connect a hot water supply to TrueSTEAM.
Water Supply LineB.
This 1/4-inch line brings cold water to TrueSTEAM
from a water pipe in your home. Your Professional
Installer may have used the plastic line provided or
a copper pipe, as appropriate.

TrueSTEAM Humidification System 69-2286EFS—03
Power CordE.
TrueSTEAM is plugged into a 120 volt AC
household electrical outlet. The power cord
provided is 6 feet long.
Water Drain LineF.
This 1/2-inch hose drains water from TrueSTEAM
to a drain in your home. The tank is drained
automatically when TrueSTEAM performs an
automatic flush cycle, and at the end of the
humidification season. You may also drain the tank
manually in order to clean the tank or perform
additional maintenance.
Safety Release ButtonG.
This button prevents the tank release lever from
accidentally moving forward and releasing the
water tank. Press and hold the button down to
move the lever forward.
Ventilation HolesH.
These holes provide airflow for the electronic
components inside the TrueSTEAM cover. Normal
maintenance includes keeping these holes clean.
TrueSTEAM CoverI.
TrueSTEAM wiring connections and electronic
components are located behind the cover. There
are no homeowner-serviceable parts here, and
the cover should only be removed by a qualified
HVAC Service Technician.
Tank Release LeverJ.
This lever locks the water tank in place on
TrueSTEAM. Press the safety release button, then
pull the lever forward to release the water tank
when removing for cleaning or service.
Light Display K.
The six lights are on or blinking to indicate
TrueSTEAM’s operational status and when service
is required. See “What do the lights tell me?” on
page 13.
TrueSTEAM ButtonsL.
The two buttons are the only controls located
on TrueSTEAM. They are seldom used by the
homeowner. (Remember, day-to-day operation is
done using your humidity control.) Use the Drain
button to manually drain the water tank. Use the
Go button to reset TrueSTEAM when restarting the
system. See “When will I press the Drain and Go
buttons?” on page 14.
Water TankM.
The tank holds the water that TrueSTEAM heats and
converts to steam. The tank can be removed
for cleaning.
Manual Shutoff ValveN.
Turn this valve by hand to either of two positions:
Lock: The valve will be locked during operation.
This turns the water supply on and locks the
solenoid valve in place. (TrueSTEAM uses the
solenoid valve to control water flow into the tank.)
Unlock: Turning the valve to “Unlock” seals the
bottom of the tank and the water supply to avoid
leaks when performing manual cleaning of the tank.
It also disengages the solenoid valve so that you
can push the solenoid back in its base to release
the tank. Once this is done, you can pull the tank
release lever forward to remove the tank
for cleaning. See “How do I clean the tank?” on
page 16.

TrueSTEAM
What should I expect from my TrueSTEAM?
Honeywell wants to make sure you know what to expect from your new TrueSTEAM installation. Make sure you
discuss these items with your Professional Installer:
Achieving Humidity Setpoint.• It may take up to a week of continuous operation to initially achieve the
humidity setpoint. This depends on factors such as weather, size of home, furnishings in the home, and
insulation. Once this is achieved, TrueSTEAM should not have to run as much to maintain humidity.
Plastic or Rubber Odor.• When the humidifier starts up after the initial installation, it is normal to smell a slight
plastic odor in the home. If the remote hose is used, there may be a slight rubber odor. These odors will go
away within a few days.
Ideal Humidity.• 35% relative humidity in typical winter weather is considered ideal for indoor comfort by
industry experts. You can adjust to your own comfort or until there is condensation on the windows. Lower the
setpoint if condensation appears.
Unit Not Humidifying.• If TrueSTEAM is not running but the humidity is below the desired setting, the humidity
control may have a frost protection setting. See “What is a frost setting?” on page 12. Note that TrueSTEAM
will not humidify while in an automatic flush cycle.
Setpoint Not Reached. • If humidity doesn’t reach the setpoint, TrueSTEAM may be under-sized for the home.
This can be due to insulation, windows, arid climate, and other environmental factors. Also, the outdoor
temperature may be too low to maintain the humidity level. If the desired humidity is still not reached, then a
larger capacity TrueSTEAM may be needed.
Home Ventilation.• Excessive ventilation exhausts humidified air and replaces it with dry air. This can make it
hard to maintain the humidity setpoint. If you are installing a ventilator, use a solution that retains moisture. An
Energy Recovery Ventilator (ERV) is recommended.
Cleaning Required Light.• If the Cleaning Required light is on, clean TrueSTEAM using the steps found in
“How do I clean the tank?” on page 16. TrueSTEAM will continue to run normally while the Cleaning Required
light is on.
Hard Water.• Your home’s water hardness determines how often TrueSTEAM must be cleaned and how often
the water filter needs to be replaced.
Energy Consumption.• You may notice a slight increase in overall energy consumption when operating any
humidifier. However, TrueSTEAM will make the home feel warmer. This allows you to lower the temperature
setting on the thermostat. Every degree lower on the thermostat can save up to 3% on heating costs.

TrueSTEAM Humidification System 69-2286EFS—03
How do I operate TrueSTEAM?
Once TrueSTEAM is installed and running, operation is automatic. Use the humidity control provided to make any
changes to the setpoint, or to turn TrueSTEAM on or off.
Your Professional Installer configured TrueSTEAM so that it only creates steam when conditions in your HVAC
system are right. Steam can only be produced when your system fan is blowing air through the duct.
Be sure to read the manual that came with your humidity control. Ask your Professional Installer if you have
questions about how to operate TrueSTEAM.
How do I use the humidity control?• Whenever humidity in the home is lower than the humidity control’s
setpoint, the control will call for humidity. Some controls will also monitor outdoor conditions to ensure indoor
humidity does not condense on windows and walls. Refer to the manual provided with your humidity control
for instructions on setting the control. There are two different types of humidity control:
Thermostat with integrated humidity
control (such as VisionPRO IAQ or
RedLINK Prestige).
Humidity control separate from the
thermostat (such as the H8908 or TrueIAQ).
OPERATION
EVERYDAY
This arrangement allows you to control
your furnace, central air conditioning, and
TrueSTEAM, all with one device.
With this arrangement, you will use your current
thermostat to control your furnace and central
air conditioning. Use the separate humidity
control to control your TrueSTEAM.
TrueSTEAM Humidification System 69-2286EFS—03

EVERYDAY
M27982
What should my humidity setpoint be? • The outdoor air temperature affects how much humidity can be
retained by the air in your home. Use this table as a starting point. Then adjust the humidity control to your
own comfort or until condensation appears on the windows.
Outdoor Recommended Relative
Temperature Humidity Setting
-20°F (-29°C) 15%
-10°F (-23°C) 20%
0°F (-18°C) 25%
10°F (-12°C) 30%
20°F (-7°C) 35%
>20°F (-1°C) 35%
What is a frost setting?• Some humidity controls (such as Prestige, VisionPRO IAQ, and True IAQ) contain
a Window Frost Protection feature which limits humidity output based on outdoor conditions. For example,
on colder days, the air in your home can hold less humidity. The humidity control automatically lowers the
humidity setpoint accordingly, to prevent frost from appearing on the inside of your windows.
OPERATION
Lower the frost setting by one value each morning that you see frost or condensation on windows. Allow 24
hours for the new setting to take effect before re-adjusting. Once you have this set to a comfortable level
without condensation, you will not need to adjust further. You can adjust your humidity setpoint without
worrying about condensation.
Manual humidity controls (such as the H8908) do not have built-in frost settings. They require you to adjust
the humidity setpoint when the outdoor temperature changes. Use higher humidity setpoints when the
temperature is warmer, and lower setpoints when the temperature is cooler.

When will I press the Drain and Go buttons?
M29628
The two buttons are used when starting TrueSTEAM and to manually drain the tank.
Drain Button: Press and hold to drain water from the
TrueSTEAM tank. See “How do I clean the tank?” on
page 16.
When the Draining light is blinking, TrueSTEAM is
actively flushing water during a manual drain.
Go Button: Press to start or reset TrueSTEAM when
the Humidifying light is blinking.
EVERYDAY
OPERATION
Pressing and holding Go also clears the blinking
Service light and stops water draining from the tank.
Drain and Go Button: Pressing and holding both the
Drain and Go buttons in at the same time will interrupt
the water cooling cycle and immediately drain
the tank.
IMPORTANT: Pressing and holding the Drain and Go
buttons together—when the Draining light is already
on—causes TrueSTEAM to empty the tank, regardless
of water temperature. Make sure the drain outlet can
handle up to 212ºF (100ºC), or wait at least 45 minutes
to allow the water to cool before using
this feature.
14
CAUTION: Scalding Hazard.
Initial temperature of the drain water may be above 140°F (60°C) and can cause scalding injury.
Make sure the drain outlet is not exposed, and use caution when pressing the Drain button.
TrueSTEAM Humidification System 69-2286EFS—03
What is the automatic flush cycle?
M29669
TrueSTEAM automatically flushes out the water tank
during the humidifying season. In the automatic
flush cycle, cold water enters the tank while water
is being emptied through the drain line. The action
of simultaneous filling and draining cools the water
to a safe draining temperature. It also dilutes water
hardness concentration to reduce mineral deposits
from forming in the tank.
At the end of the automatic flush cycle, TrueSTEAM
refills the tank with fresh water, and automatically
returns to normal operation.
Automatic flush is performed regularly, based on the number of hours that TrueSTEAM heats water and produces
steam. Automatic flush can be set to occur at any of the following intervals:
Autoflush Intervals
8 hours (recommended for hard water)
12 hours (factory setting)
20 hours (when a water softener is installed)
30 hours (when an optional RO filter is installed)
Your Professional Installer set TrueSTEAM to flush at the appropriate interval for your installation. During any
service call, the automatic flush interval can be changed, if desired.
CLEANING AND
MAINTENANCE
CAUTION: Scalding Hazard.
Initial temperature of the drain water may be above 140°F (60°C) and can cause scalding injury.
Make sure the drain outlet is not exposed, and use caution when pressing the Drain button.

M29680
M29629
M29671
Why do I need to manually clean the tank?
Manual cleaning is needed at least once each season to clean out the mineral deposits that remain in the tank
after automatic flushing. Manual cleaning is easy – just empty and remove the water tank and clean the interior
components. Then re-assemble and start TrueSTEAM up again.
When should I clean the tank?• TrueSTEAM should be manually cleaned at least once every 5 months.
(Hard water may require more frequent cleaning.) The Cleaning Required light turns on when the tank needs
manual cleaning. TrueSTEAM will still operate normally when the Cleaning Required light is on. The light will
turn off when you have cleaned the tank and re-started TrueSTEAM.
Note: The Cleaning Required light turns on when the tank drains too slowly during a manual flush cycle. (This is probably due to tank sediment.) TrueSTEAM
will still operate as normal. If during the next manual flush cycle, the tank drains normally, the Cleaning Required light will stop blinking.
CAUTION: Scalding Hazard.
Initial water temperature may be above 140°F (60°C) and can cause scalding injury. Make sure
the drain outlet is not exposed, and use caution when pressing the Drain button.
CLEANING AND
How do I clean the tank?• Follow these steps to manually clean TrueSTEAM:
Press the Drain button to initiate a flush cycle and
empty the water tank. You will know the tank is

How do I change the water filter?
Your HVAC Professional Installer chose one of these two in-line water filters for use with your TrueSTEAM. The
selection was based on the hardness of your home’s water supply. Both types of filter must be replaced at least
once every humidification season:
Polyphosphate water filter with backflow preventer.
Reverse osmosis (RO) filter with backflow preventer.
Changing the in-line polyphosphate filter.• Your Professional Installer will have secured the water filter and

Changing the reverse osmosis filter cartridges. • If the reverse osmosis filter is used in your
M29663
installation, you will need to replace two filter cartridges once every humidification season. Notice that the
reverse osmosis filter option has more components than the in-line filter and includes a separate drain line.
This option provides better filtration and prevents harder water from flowing into your TrueSTEAM.

What should I do at the end of the season?
M29678
TrueSTEAM automatically shuts down when humidity is not needed for an extended period. After several days
of inactivity, the water tank will drain and remain empty until humidity is called again. This prevents water from
stagnating inside the tank. TrueSTEAM will refill the tank with water and reset itself when your control calls for
humidity again.
Follow these maintenance steps at the end of the heating season. Doing this each year helps keep your
TrueSTEAM at peak efficiency:
WARNING! Electrocution Hazard.
During cleaning, TrueSTEAM must be unplugged if cover is removed to prevent 120 VAC from
being present in the coil and other tank components.
Clean the tank, following the procedure in “How do I clean the tank?” on pages 15 - 18. Cleaning the tank at the
end of the season ensures TrueSTEAM will be ready to perform the next time your home needs humidity.
Examine the water tank gasket. If the gasket

is cracked or split, it must be replaced before
re-attaching the water tank.
Clean out the ventilation holes in the
TrueSTEAM cover.
Clear the water drain tube connected to the solenoid
valve. Disconnect the hose and inspect for blockage,
then run hot tap water through the hose.

Check that TrueSTEAM is still installed in a
level position.
What if I go on vacation? • Even though TrueSTEAM’s water tank will drain automatically after several days,
Honeywell recommends shutting off the TrueSTEAM water supply and turning off the humidity control for
extended leaves. Upon return, turn on the water supply and reset the control to the desired setpoint.

What should I do if the Service light is blinking?
The red Service light blinks when the internal diagnostics detect a problem with TrueSTEAM. Follow these steps
to try and correct the problem:
1. Press and hold the Go button to clear the fault. If TrueSTEAM can reset itself, the Service light will
stop blinking, and TrueSTEAM will operate normally. No further action is required.
2. If the fault doesn’t clear, unplug the TrueSTEAM power cord and plug it back in to the electrical outlet.
3. If the fault reappears, wait 24 hours before calling a HVAC Professional Installer. TrueSTEAM may correct
itself automatically.
