INTRODUCTION
Must be installed by a trained, experienced technician.
Read these instructions carefully. Failure to follow these instructions can damage the product or cause a
hazardous condition.
Please read this manual completely. It is important that you understand how the Electrode Steam works, and how
to safely perform the required maintenance procedures. Read and understand all safety-related labels found on
and posted near the Electrode Steam. These labels provide additional instructions and important
safety information.
Safety Denitions
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
WARNING: Electrocution Hazard.
The Electrode Steam uses 120V or 240V, which can cause death or serious injury. Take precautions when
service is being preformed on the Electrode Steam or when removing the water tank or cover. If in doubt,
turn off the breaker which is operating the Electrode Steam 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. Be sure you know
how to turn the Electrode Steam off, and how to drain the water tank safely.
CAUTION: Steam Condensation and Freezing Water Hazard.
Be sure the Electrode Steam Humidier is located in a conditioned space, as well as having proper
condensate and drain line locations. Improper installation can result in water damage to home.
Make sure you read and understand the following safety hazards before installing, using, or working
with the Electrode Steam:
• Do not direct the steam nozzle at people.
• Water inside cylinder can be very hot. Read the warning label on the Electrode Steam and make sure
you understand the hazards of scalding hot water in the cylinder.
• 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.

INTRODUCTION
Congratulations on your new humidier.
The Honeywell Electrode Steam humidier provides the high performance and efciency of steam, with easier
maintenance than traditional humidiers.
We are sure the Electrode Steam will be a welcome addition to your home.
• How is the Electrode Steam different from other humidiers?
- The steam goes directly into your hot air supply duct, rather than evaporating from a wet pad, which requires
furnace temperature to produce humidity efciently.
- The Electrode Steam delivers humidity independent of your furnace. This allows you to achieve ideal humidity
levels in your home, year-round.
- The Electrode Steam wastes less water than ow-through humidiers.
- The Electrode Steam operates automatically, just like a thermostat, to keep your home’s humidity at the
desired level.
- The Electrode Steam is easy to maintain. Just have your HVAC professional change the steam cylinder when
the unit determines its life is about to expire.
• What safety features does the Electrode Steam have?
- Separate sensors and water monitoring (via the electrodes and software) monitor water within the tank. These
two important components prevent the tank from being over-lled, running dry, and optimize steam production
with various water qualities.
- The auto-adaptive feature monitors the Electrode Steam humidier’s water supply, current, and load. The unit
also self-tests on a regular basis, letting you know when the unit should be serviced.
• How should I get started? Your Electrode Steam must be installed by an HVAC Professional Installer. If the
Electrode Steam 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 the Electrode Steam 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 Electrode Steam.
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.

YOUR NEW
Electrode Steam
Steam Generation
• Once the unit receives a demand signal and the safety loop between terminal 1 and 2 is closed, the humidier
closes the contactor and measures the electrical current.
• If the demand is lower than the actual output the inlet valve is kept closed and output is reduced by letting the
water level in the cylinder decrease by evaporation.
• If demand is higher than the actual output, after a brief delay the ll valve is activated and water ows into the
ll cup. Water from the ll cup ows into the bottom of the cylinder through a hose connected to the drain valve
housing.
Note: The cylinder is gravity fed from the ll cup. If backpressure from the steam line is too high it will cause water
to back up in the ll cup and ow down the overow line to the drain.
• As soon as the water in the cylinder comes in contact with the energized electrodes, current ows through
the water. The resistance of the water to the electrical charge generates heat and in turn steam. The electrical
current (and steam output) increases as the level of water increases, as more of the electrode becomes
submerged. The unit continues to ll until the current matches demand or the high water sensor detects a high
water level.
• The Electrode Steam repeats the ll and boil down cycle repeatedly to match output to demand.
• Over time minerals in the water will adhere to the cylinder electrodes. The humidier will automatically ll to a
higher water level to maintain full capacity during the life of the cylinder. Eventually because of scale formation
it will no longer be possible for the humidier to reach its full capacity. The Electrode Steam software monitors
this condition and, when detected, will stop operating and ash the yellow LED in a repeating sequence of 4
ashes.
Drains
• As steam is produced, minerals are left behind, increasing the conductivity of the water. The Electrode Steam
patented auto adaptive cycle will monitor the water conductivity and perform drains to maintain the water at
optimal conductivity for peak performance.
• The auto adaptive cycle ensures cylinder life is maximized. It does this by keeping the tightest control and most
efcient use of water during the entire cylinder life.
Steam Distribution
Steam generated by the humidier may be introduced into the air in several different ways. The most common
method for adding the steam into the air is to mount a steam distributor tube in a supply air duct.
Steam Line
The steam line between the cylinder steam outlet and the distributor serves two purposes: it is used as a conduit
to transfer the atmospheric steam from the humidier to the distributor, as well as providing a means to remove
condensate.
Condensate Return
Whenever steam is distributed condensate is formed in the distribution system. Insulating steam lines is one
important way to reduce the amount of condensate formed. Steam lines are sloped so that condensate does not
collect in the lines and create a restriction to steam ow. The condensate must be collected and removed from the
system so that it does not build up and leak into the duct. Condensate can be returned to the Electrode Steam ll
cup to reduce water waste or can be fed to drain.

YOUR NEW
Electrode Steam
The Electrode Steam is available in two sizes, each with a different humidifying capacity:
The Electrode Steam produces 11 gallons per day (GPD) when run on 120 V and 22 GPD when run on
240 V. It is generally suitable for homes 8,000 to 32,000 cubic feet in size.
Which Electrode Steam model do I have?
The proper model for your home depends on many factors.
Size of the area to be humidied, 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
the Electrode Steam. Vented replaces, high exhaust from
fans, or driers can reduce humidity in your home and make
the Electrode Steam work harder.
Your Professional Installer or salesperson will have
considered these and other factors when choosing the best
Electrode Steam model for your unique situation.
Sizing
IMPORTANT: The Electrode Steam should only be installed if it has been sized properly. Do not use square feet
when sizing a humidier installation. Instead, cubic feet must be used, since the humidity is lling a volume of
space (width x length x height). Also, take into consideration the “tightness” of a home’s construction.

YOUR NEW
Electrode Steam
Honeywell wants to make sure you know what to expect from your new Electrode Steam 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, the Electrode Steam should not have to run as much to maintain humidity.
• On/Off Noise. When the humidier starts up after being off, the unit will run a self-test sequence and may a
“click” noise, engaging the ll & drain valves. This is normal .
• 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 the Electrode Steam 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 10. The Cylinder
may also be at the end of its life, in which case you will be notied by the LED sequence.
• Setpoint Not Reached. If humidity doesn’t reach the setpoint, the Electrode Steam 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.
• Home Ventilation. Excessive ventilation exhausts humidied 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.
• LED Status Lights. The HM700 user interface includes 2 LEDs that provide information about the humidier
status. Please see “What do the lights tell me?” on page 11 for more information.
• Water Draining. It is normal for the Electrode Steam to periodically drain some water automatically. This is
due to the humidier maintaining the perfect level of water conductivity and steam output.
• Water Conductivity. Your home’s water conductivity determines how quickly the Electrode Steam will produce
steam and also how often the replacement steam cylinder needs to be replaced.
• Energy Consumption. You may notice a slight increase in overall energy consumption when operating
any humidier. However, the Electrode Steam 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.

EVERYDAY
OPERATION
Once the Electrode Steam is installed and running, operation is automatic. Use the humidity control provided to
make any changes to the setpoint, or to turn the Electrode Steam on or off.
Your Professional Installer congured the Electrode Steam 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.
Ask your Professional Installer if you have questions about how to operate the Electrode Steam.
• 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 the Electrode Steam?
Steam Humidication System 33-00165—01 9
Thermostat with integrated humidity
control (such as Prestige IAQ, VisionPRO
8000, or Lyric).
This arrangement allows you to control your
furnace, central air conditioning, and Electrode
Steam, all with one device.
Humidity control separate from the thermostat
(such as the HumidiPRO) .
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 Electrode Steam.

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 8000, and HumidiPRO)
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 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.

Steam Humidication System 33-00165—01 11

CLEANING AND
MAINTENANCE
The Electrode Steam 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. The Electrode Steam will rell the tank with water and reset itself when your
control calls for humidity again.
• What if I go on vacation? Even though the Electrode Steam’s water tank will drain automatically after several
days, Honeywell recommends shutting off the Electrode Steam 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 at the end of the season?
The lights will blink when the internal dignostics systems needs attention. See LED list on page 11.
• Call customer care or your HVAC professional for all service requirements
What should I do if the LED light is blinking, or if something is
wrong?
