INTRODUCTION
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.
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.
Welcome!
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.
TrueSTEAM Humidification System 69-2286EF—01 3

INTRODUCTION
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.

YOUR NEW
TrueSTEAM
TrueSTEAM is available in three sizes, each with a different humidifying capacity:
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.
Your Professional Installer or salesperson will have considered these and other factors when choosing the best
TrueSTEAM model for your unique situation.
M29668
This label displays the model number and date code
of your TrueSTEAM.
HM506 Delivers up to 6 gallons of water each day into your home. This is generally suitable for homes

Which humidity control do I have?

YOUR NEW
TrueSTEAM
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.
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.

YOUR NEW
TrueSTEAM
M27981
Your TrueSTEAM installation includes the following parts and components that you should be familiar with:
Cold Water Connection with Shutoff ValveA.
Provides the connection from TrueSTEAM to your
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.
In-line Water FilterC.
It is likely the installer provided a water filter on
the water supply line leading to TrueSTEAM.
This helps minimize mineral deposits forming
in TrueSTEAM’s tank. For optimal performance,
replace this water filter once each humidification
season. See “How do I change the water filter?”
on page 19.
Shutoff Valve and Backflow PreventerD.
This valve was provided by Honeywell and is
required by code. It prevents water from flowing
backward in the water supply line.

YOUR NEW
TrueSTEAM
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.
IMPORTANT: Only remove the tank after it is
completely empty. See “How do I clean the tank?”
on page 16.
Light DisplayK.
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.

YOUR NEW
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.
What should I expect from my TrueSTEAM?
TrueSTEAM Humidification System 69-2286EF—01

EVERYDAY
OPERATION
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:
How do I operate TrueSTEAM?
TrueSTEAM Humidification System 69-2286EF—01 11
Thermostat with integrated humidity
control (such as VisionPRO IAQ or
RedLINK Prestige).
This arrangement allows you to control
your furnace, central air conditioning, and
TrueSTEAM, all with one device.
Humidity control separate from the
thermostat (such as the H8908 or TrueIAQ).
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.

EVERYDAY
OPERATION
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.
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.
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.

EVERYDAY
OPERATION
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.
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.
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.

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.
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:
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.
What is the automatic flush cycle?
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)
M29669
TrueSTEAM Humidification System 69-2286EF—01 15

CLEANING AND
MAINTENANCE
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.
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
draining when the Draining light is blinking.
Wait for the Empty light to turn on. (It takes about 45
minutes for the tank to drain.) This indicates that the
water has finished draining.
IMPORTANT: You can stop a manual flush once the
cycle has started by pressing and holding the Drain
button while the Draining light is already blinking. The
tank will refill and TrueSTEAM will return to normal
operation in about 5 minutes.
Turn the manual shutoff valve at the tank bottom to the
“Unlock” position.
Grip the white water valve arm and push it back to
disconnect it from the tank.
