1Introduction

The E2 controller is a microprocessor-based control system designed to provide complete control of compres­sor groups, condensers, refrigerated cas ponents related to refrigeration and building control. The E2 is the controlling
uration (RS485 I/O, Echelo n Ethernet) that includes input and output communication boards, remote communication software, and a variety of sensors, probes, and transducers.
The E2 efficiently operates all systems that support

1.1 The E2 Refrigeration Controller (RX)

The E2 RX is available in three models: the RX-300, RX-400, and RX-100. The E2 RX-300 is capable of con­trolling a single refrigeration system (including one con­denser and up to four suction groups). The E2 RX-400 is
e of controlling two separate refrigeration systems

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.

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-effi­cient 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 E2 is also compatible with a network platform called Lonworks. This is most commonly referred to as “the Echelon Network,” after the company who invented the platform, the Echelon Corporation.
In general, peripherals with control functions — such as case E2 RX and BX units — are interconnected on the Echelon Network. These controllers do most of their own computa­tion and system control, but they E2s to provide logging, alarm control, and other functions.

There are several models of the MultiFlex board that combine the functionalities of input boards, relay output boards, digital output boards, and analog output boards. The MultiFlex combination input/output boards are designed to be replacements for the 8IO Combination Input/Output Board, but the MultiFlex board provides sev eral new hardware options and software features.
The MultiFlex combination I/O boards consist of up
combination digital/analog inputs, and a combina-
to 16 tion of relay outputs, digital outputs, and analog outputs.
All boards feature both +5VDC and +12VDC output
tage points for use in powering transducers or other
vol input devices that require power.
On the RS485 Network, the MultiFlex combination
ut/output boards present themselves to Einstein, E2, or
inp REFLECS site controllers as 16AI Analog Input Boards, 8RO Relay Output Boards, 8DO Digital Output Boards, and/or 4AO Analog Output Boards, depending on what type of inputs or outputs are equipped. Dip switches are used to assign network ID numbers to each board type.

The MultiFlex Condensing Unit Board (CUB) is a
“smart” input/output board designed to control single con­densing units. A single condensing unit is a self-contained
pressor and condenser bearing unit which controls
com refrigeration in a single case line-up or walk-in cooler.
The MultiFlex CUB uses the same general hardware
ration as a MultiFlex 168AO. It is equipped with a
configu processor and extra memory to allow it to control com­pressors, condensers, refrigeration, and
defrost for a single condensing unit using on-board I/O and control algo­rithms.
The MultiFlex CUB has its own installation and opera-
tion manual, (P/N 026
-1705).
2.2.2.4 MultiFlex RTU (BX and CX Only)
Similar in design to the MultiFlex combination input / output boards, the MultiFlex RTU board is designed spe­cifically for operating package rooftop of an E2 BX or REFLECS BCU building control system. The MultiFlex RTU is designed to be a replacement for the previous generation ARTC, and is 100% compatible with all legacy E2 BX and BCU systems.

of the MultiFlex RTU. The RCB has sixteen fully configurable analog and digital input points, whereas the RTU has only eight inputs, two of which are configurable. The RCB has four analog outputs for use in controlling variable speed fans, economizers or modulating heating and/or cooling valves, whereas the RTU has only two analog outputs for use only with VS fans and economizers. The RCB also features a more sophisticated HHT interface and updated algorithms for controlling heating, cooling, dehumidification, and air quality.
The MultiFlex RCB-P (pulse control board P/N 81

logic for controlling heating and cooling functions.
The MultiFlex RCB has its own installation and opera-

The MultiFlex RTU board h relay outputs and 4 analog outputs. Most of these I/O points are reserved for sensors and input devices required to read environmental data (such as space and supply air temperature) and control all output devices that control the environment (such as heat/cool stages and dampers). Both auxiliary inputs can be configured for a variety of sensor types including any type of linear sensor. For linear sen­sors, the auxiliary inputs can be configured as By doing this, the minimum and maximum voltage and minimum and maximum Engineering Unit parameters are user configurable for these inputs. The RTU relay outputs are rated for line voltage (240VAC).
The RTU board controls the rooftop unit directly with
