1.2 The E2 Building Con-
troller
The counterpart to the E2 RX is the E2 BX, which con-
trols HVAC systems for low-rise retail, industrial, and
commercial buildings. The BX’s primary function is to
provide energy-efficient control of air handling units
(AHUs), rooftop units (RTUs), and other systems related
to environment control. In addition, the BX provides
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.
