OPERATOR’S GUIDE

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.
