ATMOX Crawlspace Ventilation System - Controlling Moisture - Component Details

The following components are parts of the ATMOX Smart System.

The ATMOX Smart System can be set up with AC Power of Fans or DC Power of Fans. This will determine some of the components being used. For details, see the Smart System - Setup Options page.

For All Smart Systems:

Control Box A

The Smart System Control Box A is the “brains” of ATMOX measuring data and controlling the system. It allows for monitoring of crawlspace conditions from inside the house or garage. It can be placed almost anywhere within reasonable distance from the crawlspace. It comes with a special mounting plate for easy wall placement. It does not need its own power supply but must be connected to the Distribution Box B via a flat telephone wire and RJ11 jacks. (Item Number: 01-100-306 for Smart System with Sensors)

Distribution Box B

This distribution box is typically installed at the crawlspace entrance door. It has an external 24V power supply, which needs to be plugged into a 115V outlet. All required and optional sensors plug into this distribution box.

Inside Climate Sensor

The inside climate sensor can be placed where needed in the crawlspace (generally in the “worst” spot). It has a holding bracket and must be connected via wire and jacks to the Distribution Box B. This sensor measures temperature and humidity outside the crawlspace. It is included with the ATMOX controls.

Outside Climate Sensor

The outside climate sensor is the same sensor as the inside climate sensor but comes with a separate installation plate designed for outdoor usage. It also needs to be connected via wire and jacks to the Distribution Box B. This sensor measures temperature and humidity inside the crawlspace. It is included with the ATMOX controls.

X-10 Transmitter
The Smart System communicates with the fans and optional dehumidifier via X-10 technology that transmits signals via existing electrical wiring. This means that wires to do not need to be run to individual fans or dehumidifiers. The X-10 transmitter is connected to the Distribution Box B with a flat telephone wire and RJ11 jacks. It also needs to be connected to a 115V outlet. It is included in the purchase of the ATMOX control set.

Optional Sensors

See details on individual pages for these options for the ATMOX Smart System.

Wood Moisture Sensor

Water Sensor

Smoke Alarm Attachment

CO Alarm Attachment

Pipe Heating Attachment

For AC Power Setup:

In-Line 15Amp Relay
Generally, all the fans will be set to come on and off at the same time. In this case, unless only 2 fans are being used, the ATMOX system will use a relay as a receiver for the X-10 information. In this case, all the electrical outlets for the fans should be wired off this relay. The function code must be set to #1 and the ATMOX system will then tell the relay whether or not to run the fans. This relay must be purchased separately from the ATMOX controls. (Item Number: 01-175-206)

SR-227 115V Receptacle
This receptacle can also serve as an X-10 receiver. When only 1 or 2 fans are being run with the ATMOX system, it may be more economical to use an SR-227 for each fan instead of a relay. If a dehumidifier is being used (or any internal fans to run with a dehumidifier), then an SR-227 will be needed for each dehumidifier/fan. The function codes will need to be set according to use.   The upper side of the outlet is the controlled side for fans to be plugged in. The lower side is just a regular outlet that could be used for some other purpose. The SR-227s must be purchased separately from the ATMOX controls as needed. (Item Number: 01-175-201)

AC-Powered or DC-Powered ATMOX Fans

With the ATMOX Smart System, any type of fan can be used. There is no limit to the number of fans triggered through the system. See full listing for best solution for your crawlspace needs: AC-Powered or DC-Powered.

For DC Power Setup:

SR-227 115V Receptacle

This receptacle serves as the X-10 receiver.  The DC Power Supply for the DC-Powered Fans will need to be plugged into this receptacle to receive proper signal. If a dehumidifier is being used (or any internal fans to run with a dehumidifier), then an SR-227 will be needed for each dehumidifier/fan. The function codes will need to be set according to use.   The upper side of the outlet is the controlled side for fans to be plugged in. The lower side is just a regular outlet that could be used for some other purpose. The SR-227s must be purchased separately from the ATMOX controls as needed. (Item Number: 01-175-201)

ATMOX Power Supply

The Power Supply is sold as 150W or 100W depending on watts needed to power DC-Fans. This will plug into the active side of the SR-227 receptacle. For larger crawlspaces, more than one Power Supply could be used if a large number of fans are needed. (Item Number: 03-800-100 for 100W ATMOX Power Supply; Item Number: 03-800-150 for 150W ATMOX Power Supply)

14 gauge Low Voltage Cable

The system uses 14 gauge low voltage cable, which is often used as landscape lighting cable. This cable attaches directly into the Power Supply through banana clips provided. The fans will connect onto the low voltage cable with snap splices provided. The cable which is sold in 100 ft sections is sold separately from the control set. It can be purchased through ATMOX or from a local hardware store. It is possible to use more than 100 ft for larger crawlspaces. (Item Number: 03-200-100)

DC-Powered Fans

The Power Supply can only be used in conjunction with ATMOX DC-Powered Fans. See full listing for best solution for your crawlspace needs. It can use any combination of those fans as needed by the layout of the crawlspace.
