Overview
The RAC system evacuates heat load from the small space and sends it to the outside corridor
or ceiling plenum return. The RAC system provides control and monitoring via a built-in web
server. Web pages, including graphs, are generated by the unit to monitor RAC settings and
environmental conditions within the room. No software other than a web browser is required
for operation and several data formats are available. The RAC system includes one internal
temperature sensor, two external temperature sensors, and ports for two additional (optional)
external temperature sensors. Optional external network cameras can also be displayed on the
RAC’s web pages.

Installation
The RAC10 relies on the building installation for protection from overcurrent. A Listed
circuit breaker is required in the building installation. The circuit breaker should be rated at
15 or 20 Amps.
Install the RAC10 so the input plug may be disconnected for service.
Installation:
1. Using appropriate hardware, mount unit into wall or dropped ceiling as detail in Mounting
Requirements Section of Instruction Sheet.
2. Plug RAC10 into appropriately rated and protected branch circuit receptacle.
Service and Maintenance:
No service or maintenance is required. Do not attempt to open the RAC10 or you may void the
warranty. No serviceable parts inside.
Two Installation Options
Wall or ceiling mount for automated heat exhaust and critical monitoring / alerts. Optional System
for room air supply required for some room and load conditions

Mounting Requirements
Drop-Ceiling Mount
1. Must use 18 gauge drop-ceiling hanger wire.
2. Attach to unit through 4 eyelets on top of unit as shown in Figure 1.
3. Supplying power receptacle must be below drop ceiling to keep power cord
out of plenum space.
4. Optional RAC-D002 duct kit may be used for interfacing to existing duct
work.

Network Overview
This product comes preconfigured with a default IP address set. Simply connect to the RAC and
access the web page with your browser.
Default IP Address
RAC units have a default IP address for initial setup and access to the unit if the assigned
address is lost or forgotten. Once an IP address is assigned to a unit, the default IP address is
no longer active. To restore the default IP address, press and hold the reset button located
below the network connector for 20 seconds. The idle and activity lights on the network
connector will both light up when IP address has been reset. The reset button is accessed
through the white, circular hole located below the Ethernet jack.
Note: Pressing the reset button under the network connector will restore the default IP address
and will also clear all password settings.

Web Interface
Overview
The unit is accessible via a standard, unencrypted HTTP connection as well as an encrypted
HTTPS (SSL) connection. The following web pages are available:
Sensors Page
The front page, Sensors, gives both instantaneous and historical views of the unit’s data. Real
time readings are provided for all data next to historical graphs.
Optional cameras may be added and their live snapshots are shown on this page. Plug-andplay external temperature sensors appear on this page when installed.
The menu bar allows access to the rest of the RAC’s functionality.

Logging Page
The Logging page allows the user to access the historical data by selecting the desired sensors
and time range to be graphed. Selected sensor values are logged into the data file at a rate of
one point per minute. Recorded data is available for download in a comma-separated values
(CSV) file.
