Informational Display Screens

Dew Point Screen

The Dew Point Screen displays the dew point outside
and inside the attic.

Temperature Screen

The Temperature Screen displays the temperature
outside and inside the attic.

The ATMOX system evaluates the outside and inside
temperature to determine whether or not to ventilate the
attic for general moisture control parameters. For heat
reduction, the ATMOX System will ventilate based on a
high inside temperature.

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 one degree 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.

27

Informational Display Screens

Relative Humidity Screen

The Relative Humidity Screen displays the relative
humidity outside and inside the attic.

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 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 attic for extended periods of time.

Fans On Screen

The Fans On Screen displays when the fans are activated.

When this screen is showing, the conditions outside are
beneficial to the attic and fans have been triggered to run.
All fans will be activated.

28

System Notifications

Humidity Too High

Missing, None, Defect (Def), with Inside or
Outside Sensor

System notifications are designed to alert you of a potential problem. The following are all possible alerts:

Under the system default settings, this humidity alarm
setting is turned to the off position, but could be active
on the system. If this alert is on for a brief period of time,
there is no reason for concern as humidity can fluctuate.
If this alert is on for an extended period of time, the attic
should be checked.

Any of these alerts indicate that there is a data connection
problem with the corresponding sensor. See page 35 for
“Troubleshooting.”

29

Testing Fans Output

All fans should be tested to make sure that they are
working properly. The best way to do this is to start
the fans manually and then go check the fans.

TIPS

After a manual start of fans, all fans will continue to operate for 24
hours. This will go back to Automatic Mode after this time. You
cannot leave system in Manual Mode for more than 24 hours.

If any fans are not running, see
Troubleshooting on pages 36 and 37.

Start the fans in Manual Mode:

Step 1: Press Arrow button.
Step 2: Make sure the red Manual light is illuminated.

Step 3: Press + button.
Step 4: Check display for “Manual on: 24h.”

Step 5: Check all fans by physically going to look at them.

Put system back to Automatic Mode:

System Settings

Most ATMOX Systems do not need any software adjustments for operation. There are instances where you
may want to adjust a setting to better suit your needs. These adjustments are described here.

Heat Reduction

Heat Reduction Mode is designed to mitigate heat
buildup in the attic. This mode allows for the attic fans to
ventilate regardless of dew point calculations once the
temperature exceeds the set inside temperature. The
default setting is an inside temperature of 99.2° F. The
trigger for Heat Reduction can be set lower or higher
within the range of 80° F and 120.8° F. The fans will
run continuously until the inside temperature goes five
degrees below the set temperature.

No Ventilation Temperature Setting

The No Ventilation setting is designed to avoid bringing
in cooler outside air in the winter time in most geographic
climates. In colder climates, it may be desired to
expand this temperature range for increased ventilation
during the winter. This setting determines the minimum
temperature inside the attic that will allow ventilation to
occur. The default setting to stop ventilation is an inside
temperature below 46° F. The setting can be set lower or
higher within the range of 1.2° F and 85.2° F.

WARNING

Improper settings can negatively

affect the operation of the ATMOX
system.

Snow Mode

Snow Mode is a special setting in the ATMOX Attic systems designed to mitigate the potential for ice damming
in climates where snow and ice buildup create challenges for the attic. Snow Mode is a tool in fighting ice
damming but needs to be viewed as part of an overall strategy and may not eliminate all issues in all attics.

Often when attics are warmer than outside temperatures, it can create issues when snow and ice begin to melt
and possibly cause water penetration into the home or attic. The Snow Mode creates a way to cool the attic
to balance the temperature differential. When the Snow Mode is turned on, the fans will run when the inside
temperature is above 32° F and the outside temperature is below 32° F in system default setting. The fans run
to dissipate the heat in the attic to resist excessive melting of snow or ice.

Snow Mode is defaulted to OFF and will need to be turned on manually.

CAUTION

In order for ventilation to reduce temperatures
effectively under Snow Mode, the fan setup may
need to be adjusted. It is important that exhaust
fans have clean outflow points and are not
restricted by snow. Additionally, there need to be
open intake points by soffit vents to get airflow to
the low corners. There may need to be additional
internal fans to get cold air to these corners.
Please discuss the fan setup with ATMOX if you
have any questions.

TIP

Snow Mode is only important when there
is snow or ice on the roof. The homeowner
may want to make it inactive during other
parts of the winter to keep attic warmer
from an energy efficiency standpoint.
