INTRODUCTION
Congratulations on your new humidifier.
The Resideo Electrode Steam humidifier provides the high performance and efficiency of steam, with easier
maintenance than traditional humidifiers.
We are sure the Electrode Steam will be a welcome addition to your home.
• How is the Electrode Steam 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.
- 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 flow-through humidifiers.
- 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-filled, running dry, and optimize
steam production with various water qualities.
- The auto-adaptive feature monitors the Electrode Steam humidifier’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 Resideo Customer Care
at 18004681502.

INTRODUCTION
Steam Generation
• Once the unit receives a demand signal and the safety loop between terminal 1 and 2 is closed, the
humidifier 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 fill valve is activated and water flows into
the fill cup. Water from the fill cup flows into the bottom of the cylinder through a hose connected to the
drain valve housing.
Note: The cylinder is gravity fed from the fill cup. If backpressure from the steam line is too high it will cause
water to back up in the fill cup and flow down the overflow line to the drain.
• As soon as the water in the cylinder comes in contact with the energized electrodes, current flows 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 fill until the current matches demand or the high water sensor
detects a high water level.
• The Electrode Steam repeats the fill and boil down cycle repeatedly to match output to demand.
• Over time minerals in the water will adhere to the cylinder electrodes. The humidifier will automatically fill
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 humidifier to reach its full capacity. The Electrode Steam
software monitors this condition and, when detected, will stop operating and flash the yellow LED in a
repeating sequence of 4 flashes.
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 efficient use of water during the entire cylinder life.
Steam Distribution
Steam generated by the humidifier 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 humidifier 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 flow. 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 fill 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 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 the Electrode Steam. Vented fireplaces, 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 humidifier installation. Instead, cubic feet must be used, since the humidity is
filling a volume of space (width x length x height). Also, take into consideration the “tightness” of a home’s
construction.

YOUR NEW
Electrode Steam
Resideo 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 humidifier starts up after being off, the unit will run a self-test sequence and
may a “click” noise, engaging the fill & 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 notified 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 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.
• LED Status Lights. The HM700 user interface includes 2 LEDs that provide information about the
humidifier 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 humidifier 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 humidifier. 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.
