ATMOX ACE 2.0 Controller with Sensors

The ATMOX ACE 2.0 controller offers the best crawl space moisture control and monitoring designed to optimize your choice of drying. This controller uses highly accurate sensors to monitor conditions in the crawl space. The sensors are constantly measuring the temperature and humidity both inside and outside the crawl space. The controller uses this data to calculate dew point to determine the best operation to improve the conditions of the crawlspace to reduce moisture.

Solving Crawl Space Moisture

The ATMOX ACE 2.0 Controller will use different forms of drying depending on the house and geographic area and climate. There are different drying options for moisture control within a crawl space and the ATMOX ACE is fully adaptable to work with your moisture control selection. The controller directs ventilation, dehumidification and air circulation.

Crawl Space Moisture Products

The ATMOX Crawl Space Products work together to improve your crawl space conditions. The ATMOX ACE 2.0 Controller can integrate a dehumidifier to dry the crawl space in peak humidity conditions keeping the crawl space at a target humidity level. The controller may also use crawl space fans in vent locations to dry out the space with outside air when ventilation is the selected drying method. In this case, the fans will exchange inside air with outside air when it’s beneficial. The ACE 2.0 Controller will do this by comparing dew point information calculated from the sensors. Some setups will also use ATMOX Internal Fans internally to distribute and circulate air evenly. The internal/circulation fans will also avoid “dead areas” within the crawl space and assist a dehumidifier.

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 (not including dehumidifier) 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 ACE 2.0 Controller is the ultimate tool for crawl space moisture. It will also provide a notification tool to monitor conditions in the crawl space to give you peace of mind.
