OPERATING PRINCIPLE
Unfinished spaces of your house need proper ventilation and/or dehumidification. The goal of
ATMOX is simple – reduce the moisture level in your crawl space and reduce both heat and
moisture levels in your attic.
The basic principle of how it works is also simple. Ventilate with “good” air from the outside only
when it will improve conditions in the space. The ATMOX controllers use sensors to measure
temperature and humidity and then calculate dew point both inside and outside. Based on the data,
the software will determine the best course of action to reduce moisture and/or heat. In a crawl space
environment, ATMOX can incorporate a dehumidifier in addition to fans that circulate internal air.
ATMOX systems are designed with a focus on energy efficiency and air quality of the home. Once
installed, the ATMOX system will operate automatically.
INFORMATIONAL SCREENS
The ATMOX display will automatically rotate through its standard informational screens about every
five seconds. To scroll more quickly, press the Information button.

The ATMOX system uses a series of calculations based on the data to determine the best action.
Temperature determines:
• If attic fans should operate for high heat. (APEX)
• If the outside temperature is within parameters to allow ventilation and to avoid air that is too cold
or too hot.
Dew point comparison determines:
• If outside ventilation will reduce moisture. Lower dew point means there is less moisture in the air.
Relative humidity determines:
• If internal fans or a dehumidifier should operate. (ACE)
• If outside ventilation should cease to optimize energy efficiency.
NOTIFICATIONS
When illuminated, the lights on the controller indicate which components on the system are currently
active. Flashing lights indicate that the system is in a time delay and may be
switching operations.
ACE DISPLAY LIGHTS
EXHAUST/INTAKE: Fans installed in exterior vent locations are in operation.
INTERNAL FANS: Fans installed inside a crawl space are in operation.
DEHUMIDIFIER: Dehumidifier is in operation.
IDLE: System has no current operation and no current alerts.
LIGHTS: Lights are in operation. Lights are turned on and off manually
by pressing the light bulb buttons. After two hours of operation, lights will
automatically turn off.
ALERT: The system is bringing an alert to your attention. Read message on
screen for more information.
WOOD MOISTURE
SNOW MODE
If installed, wood moisture measurement is a great tool to evaluate actual
moisture in the space. The readings will vary throughout the year. In
general, 10-16% wood moisture content is considered a healthy range for
an unfinished space.
(APEX) If activated, snow mode is a feature that can be turned on to
mitigate the potential for ice damming in climates where snow and ice
buildup create challenges for the attic. Snow mode is a tool used to fight
ice damming but needs to be viewed as part of an overall strategy as it
may not eliminate all issues in all attics on its own. Snow mode must be
activated during setup or in the settings menu. See SETTINGS MENU
section for instructions on how to turn on.

MAINTENANCE
ATMOX suggests a periodic maintenance inspection of your ATMOX system and unfinished space
by your installer. Conditions in and around your home are always changing. Please be aware of the
following during other times of the year:
Power Connection
If the display screen is not showing any readings, it most likely has no electrical power and is not
operating. In this case, see if something is unplugged or make sure that the outlet being used by the
controller in the unfinished space has power. It is possible for controller to operate independently
of display for several days. If display and/or controller have no power, then contact your installer for
more information.
System Alerts
If the ATMOX system is showing an alert, then the system may not be operating or may be notifying
you of another potential issue. Please check periodically to make sure that the display has no alerts
needing attention.
Fan Operation
ATMOX fans (particularly in a crawl space environment) should periodically be brushed off lightly
to keep debris from blocking ventilation. The display may not give a notification if any single fan or
group of fans are not operating. Fans should periodically be checked for operation.
Dehumidifier Operation (ACE)
If a dehumidifier is installed, follow the guidelines from the dehumidifier manufacturer with regard to
filter replacement or cleaning. Many homes do not need a dehumidifier, but there are exceptions.
If you live in a very humid climate and have excessive ground moisture being released into the
crawl space during peak summer months, it may be necessary to incorporate a dehumidifier with
the ATMOX system. Contact your installer if you have questions about your situation or need more
information.

OPERATOR’S GUIDE

Water Management (ACE)
It is important to note that the ATMOX system is a moisture management system and not a water
management system. Dry air or a dehumidifier cannot get rid of standing water in a crawl space.
Every effort should be made to drain water away from the foundation. Gutters should be cleaned out,
and downspouts should drain away from the house. If you have water intrusion in your crawl space,
this needs to be addressed separately from or in addition to your moisture problem.
FREQUENTLY ASKED QUESTIONS
What happens if there is a blackout or power outage?
The ATMOX controller and components will not run without electrical power. When power is restored,
the ATMOX controller will automatically restart and continue normal operation. If controller has no
power, then check outlet for power interruption (i.e. a tripped GFCI). All settings are retained so there
is no need to do anything on display.
Will the fans running cause too much cold air to be brought in during the winter?
In the crawl space, the controller adjusts for seasonal ventilation modes. The fans will not bring
outside air into the crawl space below a set temperature. In the attic, the fans will not bring outside
air into the attic below a set temperature which can be adjusted.
The relative humidity inside my space is higher than outside, why aren’t my fans on?
Fans ventilating with air from the outside will compare conditions between the outside air and the
inside air. The fans will run based on a dew point comparison as this gives the best measurement of
actual moisture in the air. There are times of the year when the outside temperature is high, and the
dew point will not be lower outside even though the humidity appears lower. Humidity measurements
are greatly affected by temperature and can be misleading with regard to moisture in the air.
It is raining outside, and the fans are running. What is wrong?
The answer is probably nothing. You have to trust the system even when it doesn’t seem intuitive.
The fans will be activated by dew point and not humidity levels. If a cold front comes through (even
with rain), it is possible that the colder air will have a lower dew point than the dew point in the
space. The air with lower dew point will be beneficial to the space.
I have a system alert or a question, who should I contact?
Contact your local installer first as they will have more information about the specifics of your home
and system. For any additional information or questions, contact ATMOX by phone at 704-248-2858
or email [email protected].

LOW VOLTAGE WIRING PLANNING
Do not use a separate wire for each fan. The setup is a daisy chain.
Keep total length of low voltage wire on one run to a maximum of 150 feet.
Determine where components will be placed. The controller location will dictate the origin of your wiring.
It is important to understand the function of each component in the space. The function (not necessarily the
type of component) determines which output line the component will be wired to. These functions should
be determined prior to running low voltage wire to components. Each output line uses its own separate wire
running from the controller to the component locations.
Think about how to bring the low
voltage wire to all of the components on
the same output line starting from the
controller.
Begin at the controller and start taking
the primary wire to the components. At
the end of a run, cut off any wire.
If extra length is needed on the primary
wire, attach a supplemental wire to the
primary wire to keep going in the same
direction.
If your fans split off into different
directions, you can add a supplemental
wire to the primary wire in any location
and make a Y-type split.
For details on how to connect the wiring,
see LOW VOLTAGE WIRING section.
Wiring in an attic is the same as in a crawl
space.

Follow instructions supplied with each fan for proper mounting. The
controller will determine when fan operation is beneficial to the space.
CAUTION
LIGHTS
Follow instructions supplied with each light for proper mounting. Lights
can be turned on and off manually from the display box by pressing the
buttons with the light bulbs.
DEHUMIDIFIER (ACE)
Follow instructions supplied by dehumidifier manufacturer for proper
setup and water drainage. Follow instructions with ATMOX Relay Kit
or Adapter Kit to connect dehumidifier to ATMOX controller for proper
operation and setup.
The power supply in the controller is limited to 150 WATTS. Refer to the
specification sheet of each component used to determine total power usage.
If you exceed 150 watts of power with fans or lights, you must add a power
booster, which also has a limit of an additional 150 watts. Up to four power
boosters can be used with one controller. Each of the output lines on the power
booster will mirror those designated on the synced controller.

The ATMOX controller will power and/or control components. Once installed, components will
operate automatically or on command.
The use of fans or lights not manufactured by ATMOX may not be compatible with the ATMOX
controller and may cause an electrical surge or damage the controller. Damage caused by
noncompatible components or incorrect wiring is not covered under the ATMOX product
warranty.
Using components on the wrong output line may lead to improper operation of the ATMOX
controller and have a detrimental effect. As the installer, you should have a plan on effective
placement of components. Follow specific guidelines on wiring configuration by controller and
power booster, as described in PLANNING section.
CAUTION
Dehumidifier must have its own electrical outlet within distance of
dehumidifier electrical cord.

CAUTION Do not plug in the controller or booster until all wiring is complete.
ATMOX components such as fans and lights are designed for connection to controllers via
low voltage wiring.
Use 14/2 low voltage wire. This wire can have different grooves
or writing. Pick one side as positive and the other as negative. Be
consistent throughout installation. ATMOX suggests grooved side
as NEGATIVE and smooth side as POSITIVE.
Quick Splice Connectors
connect connector wire to the
low voltage wire.
Low voltage wiring connects to
controller in terminal blocks. The
colored block is POSITIVE. The
black block is NEGATIVE. Each
color is used for a different function.
Connector Wire connects
the ATMOX component to
low voltage wire with quick
splice connectors. Black wire
is POSITIVE. White wire is
NEGATIVE.
OVERVIEW
TIP
Before you begin any wiring, please follow these important steps:
• Determine function of each component being installed and determine which output line the
component needs to be wired to. Review page 11 and 12 in the PLANNING section.
• Refer to specification sheet of each component to determine watts used. The controller and
power booster each have the ability to power 150 watts.
• If your total usage exceeds 150 watts, then you need to split the components up between the
controller and a power booster. Output lines will function the same on both units once they have
been synced properly. Instructions on power booster setup are on page 24.
Note: The power booster will not work independently of the controller except for the use of the
constant power output.
Once you have finished wiring, proceed through the display setup and, if applicable, the booster
syncing process.
