ATMOX APEX 2.0 Controller with Sensors

The ATMOX APEX 2.0 Controller offers the best in attic heat and moisture control through the use of smart ventilation. It is a sophisticated controller that accurately measures the inside and outside conditions of your attic before running the ATMOX energy efficient fans. Sensors inside the attic and outside measure temperature and humidity. The APEX Controller uses this data to determine when it is best to operate fans to reduce attic moisture and heat. The fans will run only when the air outside is beneficial to replace the inside air with drier fresh air.

Solving Attic Moisture

The ATMOX APEX Controller has a unique focus on reducing attic moisture. There is no other attic solution quite like it. The APEX Controller 2.0 uses sensors to measure both inside and outside temperature and humidity, and then uses this information to calculate dew point. Knowing the conditions of the inside and outside air allows the controller to determine when fans should run to exchange the air in the attic.

Solving Attic Heat

In order to solve attic heat there must be an exchange of air within the attic space. The ATMOX APEX Controller uses data from highly accurate ATMOX Sensors to determine when the outside air is best. The ATMOX controller directs the operation of ATMOX fans and provides a notification tool for homeowners. Various mounting options are available to accommodate different construction styles. This customization allows the ATMOX fans to  spread airflow evenly throughout your attic space.

Attic Products

Learn how all the ATMOX Attic Products work together. Attics will use ATMOX energy efficient fans to dry out the space with outside air. The fans will be placed in gables, ridge vents or other openings depending on your construction. Fans may also be set up internally to move air across attic spaces or to get to hard to reach areas and balanced airflow to prevent the buildup of heat and moisture.

The ATMOX fans and lights are all low voltage, so they will receive all of their power by using low voltage wire attached to the controller. This means that the setup of components will run from one electrical outlet. This allows for a simple installation, and it minimizes or eliminates the need for an electrician at the installation.

The ATMOX APEX Controller 2.0 is the ultimate tool for attic moisture. It will also provide a notification tool to monitor conditions in the attic to give you peace of mind.
