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.

How should I get started? Your TrueSTEAM must be installed by an HVAC Professional Installer. Ifthe

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 }/our 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

TrueSTEAM Humidification System 69-2286EF--01

How does TrueSTEAM work?

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.

The heating element coil heats water in the tank to the boiling point.

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.

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.

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.

m 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.

TrueSTEAM Humidification System 69-2286EF--01

Which TrueSTEAM model do l 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 _sgenerally suitable for homes

4.000 to t4.400 cubic feet in size.

HM509 Delivers up _o9 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

komes 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.

Your Professional Installer or salesperson will have considered these and other factors when choosing the best TrueSTEAM model for your unique situation.

This label displays the model number and date code of your TrueSTEAM.

TrueSTEAM Humidification System 69-2286EF--01

Which humidity control do l 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 (TruelAQ 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 wil! 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 Humidification System 69-2286EF--01

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.

What TrueSTEAM parts do ! need to know?

Your TrueSTEAM installation includes the following parts and components that you should be familiar with:

A. Cold Water Connection with Shutoff Valve

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 Line

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.

M29679

C. In-line Water Filter

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.

M27981

D. Shutoff Valve and Backflow Preventer

This valve was provided by Honeywell and is

required by code. It prevents water from flowing backward in the water supply line.

TrueSTEAM Humidification System 69-2286EF--01

E, Power Cord

TrueSTEAM is plugged into a 120 volt AC

household electrical outlet. The power cord provided is 6 feet long.

F, Water Drain Line

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.

G. Safety Release Button

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.

H, Ventilation Holes

These holes provide airflow for the electronic components inside the TrueSTEAM cover. Normal

maintenance includes keeping these holes clean.

TrueSTEAM Cover 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.

Jm Tank Release Lever

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

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.

Lm TrueSTEAM Buttons

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.

M, Water Tank

The tank holds the water that TrueSTEAM heats and converts to steam. The tank can be removed for cleaning.

Hm Manual Shutoff Valve

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.

IMPORTANT: Only remove the tank after it is

completely empty. See "How do I clean the tank?"

on page 16.

TrueSTEAM Humidification System 69-2286EF--01

What should ! 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 Hot 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.

lO TrueSTEAM Humidification System 69-2286EF--01

How do ! 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).

,o... 72°

This arrangement allows you to control your furnace, central air conditioning, and

TrueSTEAM all with one device.

Humidity control separate from the

thermostat(sUchastheHago8

With this arrangementl you wil use your current therm0stat to contr01 y0ur furnace and central

air conditioning. Use the separate humidity

control to control your TrueSTEAM. .........................

TrueSTEAM Humidification System 69-2286EF--01 11

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

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.

M27982

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.

12 TrueSTEAM Humidification System 69-2286EF--01

What do the lights tell me?

The six lights show TrueSTEAM status and indicate when service needs to be performed.

Power (Green). On indicates the power cord is

plugged in.

Humidifying (Green). Lit - TrueSTEAM is actively heating water and creating

steam. Blinking - TrueSTEAM is resetting or filling. This is

usually done when plugging in the power cord, and

lasts for about 3 minutes. You can press the Go button to reset TrueSTEAM immediately. Dark - TrueSTEAM is in Ready mode - it can heat water and produce steam when a humidity call comes

from the control.

M29628

Empty (Green). When on, the water tank is empty and can be removed for manual cleaning.

Service (Red). Blinking - The number of blinks (1-18) shows the type

of fault TrueSTEAM has detected. See "What should I

do if the Service light is blinking?" on page 22.

Draining (Yellow). Blinking - TrueSTEAM is flushing water from the tank

for manual cleaning. See "What is the automatic flush

cycle?" on page 15.

Cleaning Required (Yellow). On - Indicates that the tank needs to be cleaned

manually. See "How do I clean the tank?" on page 16.

TrueSTEAM Humidification System 69-2286EF--01 13

When will l press the Drain and Go buttons?

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.

M29628

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 212°F (100°C), or wait at least 45 minutes to allow the water to cool before using

this feature.
