KEY BENEFITS
WHY ATMOX?

Operating Principle
Crawlspaces need dry and proper ventilation. The goal of ATMOX is simple – reduce the moisture and humidity
level in your crawlspace.
The basic principle of how it works is also simple. Ventilate with “good” air from the outside only when it will
improve the conditions in the crawlspace. Using sensors, ATMOX calculates dew point inside and outside your
crawlspace to determine when the fans or dehumidifier should run. The fans allow for natural air circulation into
the crawlspace.
An optional dehumidifier, if equipped, is only used when the system cannot find “good” air from the outside,
making the system energy efficient and environmentally friendly.
Once installed, the ATMOX System will operate on its own and automatically. The system will adjust for seasonal
changes as needed. There is no need to manually make any changes to the system.

ATMOX Settings
The ATMOX System is a fully automatic and software-
controlled moisture management system. The system
continually measures conditions inside and outside to
determine the best course of action for your home and
crawlspace.
The system is preset to the proper settings. It is very
rare for adjustments to be necessary.
If you have inadvertently made changes by pressing
buttons, talk to your installer about setting system back
to its default settings.
Do not adjust the settings on your system without
talking to your installer. Improper settings can
negatively affect the operation of the ATMOX system.

Informational Display Screens
The ATMOX Controller will automatically rotate through
its standard informational screens about every fifteen
seconds.
System Screen
This screen displays the name of the ATMOX model
and the installed software version.
To view all screens, you can wait and watch as it scrolls
automatically.
For faster rotation of screens, you can manually change
the display. Press the M Button on the panel to scroll
through each of the screens.
The M Button will also light up the screen for easier
viewing.
Note: The system will continue to auto rotate even while
the M Button is being pressed.

Informational Display Screens
Dew Point Screen
The Dew Point Screen displays the dew point outside
and inside the crawlspace.
Temperature Screen
The Temperature Screen displays the temperature
outside and inside the crawlspace.
The ATMOX system evaluates the outside and inside temperature
to determine whether or not to ventilate the crawlspace. If the
temperatures are too cold or too hot based on several calculations,
the system will not ventilate with outside air. The ATMOX system
automatically adjusts its temperature parameters for different times of
the year.
Note: If the outside sensor is located in direct sunlight, it will often
heat the metal housing causing the sensor to read a temperature that
is higher than the ambient outdoor temperature. The overall outside
moisture calculations (dew point) will not be incorrect, so this generally
does not affect basic operation of the ATMOX system in determining
when fans should be running.
Dew point is the key to the ATMOX system. Dew point is calculated
from the temperature and humidity measurements and gives you the
best indicator of moisture in the air. A higher dew point means there
is more moisture in the air, and a lower dew point means there is less
moisture in the air. The ATMOX system does not activate ventilation
on an absolute number but instead uses a comparison of air in the
two locations. Under most circumstances, the fans will ventilate when
the outside dew point is 1 to 1.5 degrees lower than inside dew point.
There are some exceptions to this built into the software, for example
temperature parameters need to be met. There is also a time delay
of 15 to 30 minutes to conserve energy and avoid constant on and
off. This means that you will not always see instantaneous change in
operations.

Informational Display Screens
Fans On Screen
The Fans On Screen displays when the fans are
activated.
Relative Humidity Screen
The Relative Humidity Screen displays the relative
humidity outside and inside the crawlspace.
Relative humidity is measured by the sensor along with temperature
in each location and is used to calculate dew point. An important
component of relative humidity is the word “relative.” Humidity is
relative to temperature and can fluctuate significantly with changes
in temperature. ATMOX ventilates based on a dew point comparison
for this reason. It is possible for the humidity outside to be higher
than inside but to still trigger the fans to run. It all depends on the
corresponding temperature. In general, the ATMOX system is not
looking to target an exact humidity level but instead is looking to have
variations mirroring the outdoors. The goal is not to have extremely
high humidity in the crawlspace for extended periods of time.
There are some operations on the ATMOX system that are triggered by
inside humidity levels. Under default settings, if the crawlspace humidity
exceeds 80%and outside dry air is not beneficial, then the controller
will activate the Orange and Yellow outputs used for internal fans and
an optional dehumidifier. Once activated, the fans and/or dehumidifier
will continue operation until the inside relative humidity is below 75% or
when outside air is drier. Your system will automatically trigger these
outputs even if your setup does not have a dehumidifier or internal fans.
The relative humidity setting to activate Yellow and Orange outputs is
adjustable. Contact your installer if you have questions about custom
settings.
When this screen is showing, the conditions outside are beneficial to
the crawlspace and fans have been triggered to run. All fans plugged
in the Red and Orange outputs will be activated.
Dehumidifier On Screen
The Dehumidifier On Screen displays when the Yellow
and Orange outputs are activated.
When this screen is showing, the conditions outside are not beneficial
to the crawlspace and the inside relative humidity is elevated. All
components plugged in the Yellow and Orange outputs will be
activated. It is important to note that this screen will come on
regardless of whether or not a dehumidifier is actually installed with
the system.

This light Indicates there is an alert on the
system. Check screen to identify the reason
for alarm.
MANUAL
Under normal automatic operation, this light
