1.2The 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-300and the E2 BX-400 is the total number of building control devices that may be operated by a single controller. Table 1-2shows the differences between capabilities for the BX-300 and BX-400.
