The E2 RX and BX controllers are among the most versatile and customizable control system products avail- able on the market. Because of the enhanced capabilities of the E2s, programming, installation, and operation of E2 and its accompanying peripherals are supported by several different Retail Solutions publications. All of the publica- tions listed below can be ordered by contacting Retail Solutions:

•E2 Installation and Operation Manual for RX Refrigeration, BX HVAC, and CX Convenience Store Controllers (026-1610) - The manual you are currently reading. The Installation and Operation Manual covers hardware installation, network setup, and important operator functions such as viewing status screens or logs, and performing manual defrosts.

The Quick Start section (Chapter 8) is designed to guide you quickly through setup of the most simple and vital refrigeration control applications (such as suction groups and condensers). More detailed information is included in the online help.

•Router and Repeater Installation Guide (P/N 026- 1605) - If you have a large site with 64 or more devices on the Echelon Network, you might require the use of a router or repeater to properly set up your Echelon Network. The Router and Repeater Installation Guide will help you determine when a router or repeater should be used, how and where to set it up, and how to configure the E2(s) on the net- work to interact with the router or repeater.

•Emerson Retail Solutions Product Technical Sheet Binder (P/N 026-1904)- The product sheet binder gives important installation information about sensors, transducers, thermostats, and other essential items that are a part of every Retail Solu- tions control network. The product sheet binder is not necessary for field installation instructions; however, it may be a useful reference for contrac- tors and OEMs who require more information about a specific peripheral.

•MultiFlex ESR Installation and Operation Man- ual (P/N 026-1720)- From general information to details on mounting, wiring, and heat dissipation, the MultiFlex ESR manual provides the informa- tion you need to install and operate the MultiFlex ESR board, in addition to valuable information on software setup and valve control.
