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.
