• It may take up to a week of continuous operation to achieve the humidity set point,
depending on weather, size of home, furnishings in the home, insulation, etc.
• 35% relative humidity in a typical winter humidifier market is considered ideal by industry
experts. Homeowner can adjust to their own comfort or until there is condensation on the
windows. Lower the setpoint if there is condensation.
• If TrueSTEAM is not humidifying but the humidity is below the setpoint, it is likely the humidity
control has a frost protection setting, or TrueSTEAM is in a drain cycle mode.
• Excessive ventilation will exhaust humidified air outside and replace it with dry air, making
it difficult to maintain humidity set point under certain conditions. If installing a ventilator, a
solution that retains moisture, such as an Energy Recovery Ventilator (ERV), is preferable for
maintaining indoor humidity set points.
• If the home can't achieve the setpoint, the unit may be under-sized for the home. This can
be due to insulation, windows, arid climate, etc. or the outdoor temperature may be too
low to maintain adequate humidity levels. Honeywell recommends waiting for the outdoor
temperature to moderate closer to 20°F (-6°C). If the selected humidity levels are not
achieved, then a larger capacity model may be needed.
• At startup, it is normal to experience a slight plastic odor in the home, depending on the
amount of ventilation. If the remote hose is used, there may be a slight rubber odor. These
odors will dissipate within days of installation.
• If the PRESS EMPTY light is blinking, clean TrueSTEAM per the steps found in the
maintenance section. TrueSTEAM will continue to humidify as normal while PRESS EMPTY is
blinking.
• The home's water hardness will determine how often TrueSTEAM needs to be cleaned and
how often the included water filter needs to be replaced.
• Data shows there may be a slight increase in the homeowner's energy consumption when
operating any humidifier. However, TrueSTEAM will make the home feel warmer, allowing the
homeowner to lower the temperature setting on the thermostat. Every degree lower on the
thermostat can save up to 3% on heating costs.
