extensive sensor control, logging, and graphing features
that allow the user to view accurate real-time information
about system conditions. The BX is equipped with many
power monitoring and demand control features that give
you the information you need to keep your site’s energy
consumption low.
The E2 BX is available in two models: the BX-300 and
BX-400. The only significant difference between the E2
BX-300 and the E2 BX-400 is the total number of building
control devices that may be operated by a single controller.
Table 1-2 shows the differences between capabilities for
the BX-300 and BX-400.

Store Controller
The CX controls HVAC, lighting, and refrigeration
systems for convenience store and small-box retail facili-
ties. The CX’s primary function is to provide energy-effi-
cient control of rooftop units as well as refrigeration and
defrost control of display cases and walk-in boxes. In
addition, the CX provides extensive sensor control, log-
ging, and graphing features that allow the user to view
accurate real-time information about system conditions.
The CX is equipped with many power monitoring and
demand control features that give you the information you
need to keep your site’s energy consumption low.
The E2 CX is available in three models: the CX-300,
CX-400, and CX-100. The only significant difference
between the E2 CX-300 and the E2 CX-400 is the amount
of C-Store equipment that may be operated by a single
controller. The CX-100 is a low-cost alternative to the CX-
300 with fewer capabilities and a monochrome display.
Table 1-3 shows the differences between capabilities for
the CX-300 and CX-400.
