The E2 Convenience
Store Controller (CX)
The E2 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.
