Setting Homeowner Expectations
Make sure the homeowners know what to expect from their TrueSTEAM humidifier, Discuss the following points
with the homeowners and answer any questions they have,
,, Achieving Humidity Setpoint. It may take up to a week of continuous operation to achieve the humidity
setpoint. This depends on such factors as weather, size of home, furnishings in the home, and insulation.
,, Plastic or Rubber Odor. At startup, 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 by industry experts.
Homeowners can adjust to their own comfort or until there is condensation on the windows. Lower the
setpoint if condensation appears.
,, Unit Hot Humidifying. If TrueSTEAM is not running but the humidity is below the setpoint, the humidity
control may have a frost protection setting. TrueSTEAM will not humidify while in a drain cycle mode.
Setpoint Not Reached. If humidity doesn't reach the setpoint, TrueSTEAM may be undersized for the home.
This can be due to factors such as insulation, windows, and arid climate. Also, the outdoor temperature may
be too low to maintain the humidity level. Wait for the outdoor temperature to warm closer to 20°F (-6°C). If the
desired humidity is still not reached, then a larger capacity TrueSTEAM may be needed.
Home Ventilation. Excessive ventilation sends moist air outside and replaces it with dry air. This can make it
hard to maintain the humidity setpoint. If 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
the "Routine Maintenance" section on page 24, or in the Homeowner's Operating Manual. TrueSTEAM will
continue to run normally while this light is on.
Hard Water. The home's water hardness determines how often TrueSTEAM must be cleaned. A water
hardness test kit is provided with your TrueSTEAM. It will help you determine the cleaning interval and filter
requirements for your TrueSTEAM.
Energy Consumption. There may be a slight increase in overall energy consumption when operating
any humidifier. However, TrueSTEAM will make the home feel warmer. This allows the homeowner 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 69-2285EF--01
Important Installation Requirements
Personal Safety
Wear safety glasses while installing TrueSTEAM.
Do not cut into any air conditioning or electrical line.
Follow professional safety standards and all local regulations.
Mounting Location
Mount TrueSTEAM in a level position to avoid water damage or heating element failure.
Install TrueSTEAM on the supply duct. Use the Remote Mounting Kit if duct mounting is not possible.
Do not install TrueSTEAM where the ambient temperature is lower than 34°F (1.1°C) or higher
than 104°F (40°C).
Mounting area must be strong enough to support TrueSTEAM's weight when full of water (up to 15 Ibs.).
Choose a location that is well ventilated. Do not install TrueSTEAM in completely enclosed spaces, such as a
cabinet or unventilated closet.
Allow at least 1 foot clearance to ventilation holes in the TrueSTEAM cover. Do not cover the holes. Covering
them can increase the temperature inside TrueSTEAM and shorten its life.
Do not mount directly to duct board. The remote mount nozzle attachment is allowed only with a Honeywell
duct board adapter kit. See "Appendix B: Parts List" on page 35.
If used near a pool or spa, make sure TrueSTEAM can not fall into the water or be splashed. Also, ensure
TrueSTEAM is plugged into a ground fault interrupted (GFI) outlet.
Duct Nozzle
Do not install the duct nozzle into a supply duct with static pressure exceeding 0.5 in. w.c.
Do not install the duct nozzle through wooden sidewalls (e.g., floor joist).
If the duct has exposed insulation on the interior, be sure the nozzle extends beyond the insulation. Clear
away excess insulation at the insertion point, or replace a section of insulated duct (approximately 6 in. x
6 in.) with rigid, non-insulated sheet metal.
Allow at least 4 in. clearance between nozzle outlet and any interior duct to avoid water condensation.
Mount TrueSTEAM where the nozzle outlet has a minimum 24 in. of downstream open air space.
Water Drainage
Consult local plumbing codes for drain size, material, and maximum temperature allowed.
TrueSTEAM Humidification System 69-2285EF--01
Choosing a Mounting Method
Before installing TrueSTEAM in a home, you must decide which mounting method you want to use:
Which is right for you?
DUCT MOUNTING - if you can mount
TrueSTEAM onto the supply duct of
the HVAC system:
[] The generated steam goes directly into the
supply duct.
[] This is the simplest type of installation, but
it requires that a suitable mounting location
can be found on tlqe supply duct.
REMOTE MOUNTING - if a suitable
mounting location can not be found
on the supply duct:
The TrueSTEAM can be mounted up to 20
feet away from the supply duct for
select models.
A remote hose must be installed to carry
steam from TrueSTEAM to the supply duct.
You will need to use a remote mounting kit
_see "Appendix B: Parts List" on page 35).
This manual covers duct mounting of TrueSTEAM. For Remote Mounting Instructions, see "Appendix C: Remote
Installation" on page 36 or "Document 69-2317" (included with Remote Mounting Kit).

TrueSTEAM Humidification System 69-2285EF--01
STEP THREE: Install Mounting Bracket to the Duct
M29600
Position the template on the supply duct:
Make sure the template is level and in the desired
position on the duct.
Ensure proper clearances from A-coil.
Make sure the duct nozzle will have proper
clearances from duct walls.
Minimum 4-inch clearance from nozzle outlet to
any duct wall.
Minimum 24 inches of downstream open duct air
space. (Needed to prevent water condensation.)
Drill the 1-3/4 inch hole.
Secure the mounting bracket to the duct, using four
self-drilling sheet metal screws provided.
STEP FOUR: Install TrueSTEAM onto the Mounting Bracket
Make sure the foam gasket is positioned correctly
over the nozzle.
Lift TrueSTEAM into place against the mounting
bracket. Insert the nozzle directly into the duct hole.
Check the foam gasket - it must form a tight seal in
the duct hole.
Push down to secure TrueSTEAM to the bracket arms.

Choosing the Proper Water Filter
[] I have compieted the duct mounting installation, including installing the duct nozz!e and securely
mounting TrueSTEAM t0the duct
TrueSTEAM uses a water tank to hold water in place as it is converted to steam. When water is boiled, the
dissolved minerals in the water (known as water hardness) fall out in solid form. This solid mineral fallout is
known as scale or sediment.
The quantity of scale or sediment and the time it takes to accumulate in the tank depends on the hardness of the
TrueSTEAM water supply. The harder the water, the more dissolved minerals it holds. This leads to faster solid
mineral accumulation in the tank.
Honeywell provides water filtration solutions that fit the needs of the home's water hardness. A water hardness
test kit is included with TrueSTEAM to assess which filter is needed.
STEP ONE: Test the Water Hardness
M29684
Fill the plastic tube with water directly from the
TrueSTEAM input water source.
Note: It is important to test the specific input to TrueSTEAM, as it may
differ from the faucet taps in the home.
Dip the colored end of one of the test strips into the
tube's water for 3 seconds.
Remove the test strip. Do not shake the strip.
Wait 20 seconds and then match the test strip's
color to the closest color block on the water
hardness scale.
Note: Strip color results are no longer valid after one minute.

Before Wiring TrueSTEAM
TrueSTEAM wiring is different from evaporative pad humidifier wiring, in addition to solenoid water valve
actuation, TrueSTEAM can monitor system power and regulate system fan operation.
Using the DiP Switches
The wiring features are configured by DiP settings, which are described under the TrueSTEAM cover.
STEP ONE: Remove the TrueSTEAM Cover
Loosen the cover screw.
Slide cover out from front.
With the cover removed, you will see six DIP switches
to the left of the user interface panel. This manual
refers to DIPs 1-6 from left to right.

You need to decide on the configurations you will use before wiring the TrueSTEAM, These decisions will affect
how the connections are made, how the DIP switches are set, and how TrueSTEAM operates for the homeowner.
STEP ONE: Make Power Monitoring Decision
Power Monitoring is a configuration that allows TrueSTEAM to humidify only when it has confirmation that the
HVAC system transformer has power. This helps prevent steam from entering the supply duct when the HVAC
system is not operating. There are two ways to configure power monitoring, depending on the humidity
control used:
,, CONFIGURATION 1 - Using a thermostat with integrated humidity control
,, CONFIGURATION 2 - Using a humidistat separate from the thermostat
Which is right for you?
CONFIGURATION 1 -- using a thermostat
with an integrated humidity control such as
VisionPRO IAQ or Prestige -- is ideal for
contractors who:
[] Want simplified wiring - TrueSTEAM
only needs to be connected to the HUM
_erminals from the control.
Provide integrated system and accessory
control in the living space.
[] Are using VisionPRO IAQ or
Prestige thermostat.
Proceed to "Wiring Basics: Conf_uration 1"
illustration at top of next page.
CONFIGURATION 2 u using a humidistat
separate from the thermostat such as H8908
or TruelAQ -- is ideal for contractors who:
[] Use a humidity control separate from
the thermostat.
[] Wish to locate the humidity control on the
return duct.
Proceed to "Wiring Basics: Configuration 2

The thermostat is powered by the
system transformer. In this configuration,
the thermostat must have power or
TrueSTEAM will not be able to
produce steam.
Because the thermostat knows when the
system transformer has power, set DiP 4
to UP, so that it is not looking for an R input
from the system R.

TrueSTEAM HVAC System
TrueSTEAM generally supplies power
to the humidistat. In this configuration,
TrueSTEAM must monitor HVAC system
power to determine if humidity is allowed.
Leave DiP 4 in the DOWN position (factory
setting), and wire the HVAC system R and
C to the TrueSTEAM R and C. TrueSTEAM
will verify power is present before allowing
steam production.
TrueSTEAM Humidification System 69-2285EF--01
15
STEP TWO: Make System Fan Regulation Decision
System Fan Regulation is a configuration that requires TrueSTEAM to monitor the HVAC system fan and make
sure the fan is on if humidity is needed. This helps ensure that airflow will distribute humidity into the living space,
and prevents water condensation in the duct. There are two ways to configure system fan regulation, depending
on the humidity control used:
,, CONFIGURATION 1 - Using a thermostat with integrated humidity control
,, CONFIGURATION 2 - Using a humidistat separate from the thermostat
Which is right for you?
CONFIGURATION 1 -- using a thermostat
with an integrated humidity control such as
VisionPRO IAQ or Prestige -- is ideal for
contractors who:
Want integrated control of the humidifier and
HVAC system in the living space.
[] Want the system fan to turn on immediately
upon a call for humidity.

TrueSTEAM will relay power from its RT
terminal to GF and out to HVAC system
G to ensure the fan has power for
humidity calls.

STEP THREE: Make Add-On Air Proving Decision
In addition to monitoring system power and fan regulation, TrueSTEAM can monitor physical air movement
through an optional add-on air proving device. If an air proving device is added, TrueSTEAM can create steam
only if the fan is moving air through the supply duct.
