• Furnace filter is dirty and needs replacement.
• Bypass tube and humidifier not installed parallel, use hard
ducting – use hard ducting for any elbows – take the most
direct route when ducting.
• The bypass tube or humidifier is installed in front of air-
conditioning coils or is blocked in some other way – move to
another location and ensure maximum air flow.
• The humidifier and bypass tube are installed on the same duct
– you must install the unit on either the supply or return and
the bypass tube on the opposite duct or the unit will not work.
• Your furnace does not supply air hot enough to maximize
output. If you use a heat pump or a high efficient furnace
you may see this problem. You may want to consider the
use of supplemental humidification such as floor or table
top humidifiers.
POSSIBLE CAUSE: The outside conditions have been
extremely cold -15°C to -20°C for extended periods.
During extended periods of extreme cold your
humidifier is working to replenish the moisture which is
being lost in the home's structure, furniture, and other
household items. As the humidifier is working the cold
weather is continually drying out the house. Because the
temperature drop outside the water temperature being
supplied to the unit is also low, a 5°F drop in water
temperature will reduce the output of the unit by as
much as 15-25%
REMEDY: There is no remedy for this situation – except time.
Your humidifier has a stated output. All you can do is ensure
that your unit is working at its peak performance. (See section
in the instructions.)
All homes bring in outside fresh air – whether through
infiltration (cracks) or through the use of HRV's. This is
imperative to ensure proper indoor air quality. The
amount of outside air brought in will directly affect the
humidity levels in your home, and the colder that air is
the more moisture it will take from the humidifier.
PROBLEM: HUMIDIFIER IS NOT CYCLING ON
WHEN THE FURNACE TURNS ON
There may be a time lag occurring between your furnace
turning on and the humidifier turning on. Anything ranging
from 60 – 120 seconds is considered acceptable, as the unit
is waiting to sense the minimum air temperature required to
evaporate water. As well it is waiting for a minimum
temperature rise to occur over a one minute period. This is
a safe guard to ensure efficient water use.
POSSIBLE CAUSE: Humidistat is not turned on.
REMEDY: Adjust humidistat.
POSSIBLE CAUSE: Unit is not plugged in.
REMEDY: Plug in unit.
POSSIBLE CAUSE: The air going through the unit is not
hot enough. For this unit to work it must sense a 4°C
temperature rise over 1 minute of time and the air
temperature must be at least 30°C. This ensures that the
humidifier is using water efficiently. If your furnace does
not supply the require temperatures you will have to
purchase and install a pressure switch.
REMEDY:
• Adjust bypass damper to fully open position.
• Ensure the bypass tube is fully stretched out tight.
• Furnace filter is dirty and needs replacement.
• Bypass tube and humidifier not installed parallel, use hard
ducting – use hard ducting for any elbows – take the most
direct route when ducting.
• The bypass tube or humidifier is installed in front of air-
conditioning coils or is blocked in some other way – move to
another location and ensure maximum air flow.
• The humidifier and bypass tube are installed on the same duct
– you must install the unit on either the supply or return and
the bypass tube on the opposite duct or the unit will not work.
• Your furnace does not supply air hot enough to activate the
control – you will have to install a flow through pressure switch
(through our parts and service line) or bypass the humidifiers
control and have the unit hardwired to your furnace by an
electrician or hvac professional.

PROBLEM: HUMIDIFIER IS NOT CYCLING
OFF WHEN THE FURNACE TURNS OFF
POSSIBLE CAUSE: Temperature set point on the control is not set
properly for your furnace. The
temperature settings.
REMEDY: Follow the section in the instructions to customize the
humidifier's control to your furnace's cycles.
POSSIBLE CAUSE: The temperature in the furnace is not
dropping fast enough to activate the control's off cycle. The
control will work on all typical residential furnace
installations available today. However if for some reason you
have customized your furnace installation, or are using
various supplemental heating apparatus for your home (fire
place – gas or wood, radiant floor, etc.), have made additions
or renovations to your home without up grading your heating
system, or have not properly maintained your home's heating
system, it may by necessary to use our pressure switch or
have the unit interlocked with your furnace by an electrical
or HVAC professional.
