The E2 controller is a microprocessor-based control
system designed to provide complete control of compressor groups, condensers, refrigerated cases, and other components related to refrigeration and building control. The
E2 is the controlling component of a three-network configuration (RS485 I/O, Echelon
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
refrigeration (including compressor racks and condensers)
and other components not directly related to refrigeration
control, such as HVAC systems, anti-sweat heaters, and
sensor control modules.

1.1The E2 Refrigeration
Controller
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
capable of controlling two separate refrigeration systems
(including two condensers and up to four suction groups).
The RX-100 is a low-cost alternative to the RX-300 with
fewer capabilities and a monochrome display.
The E2 RX is primarily designed to control temperature and defrost in refrigerated cases using either direct
control (connected to the E2 via I/O boards or ESR8
lineup control boards) or by using CC-100 case control
boards (connected via the LonWorks Network).

1.2The E2 Building Controller
The counterpart to the E2 RX is the E2 BX, which controls 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

1.3The E2 Convenience
Store Controller
The CX controls HVAC, lighting, and refrigeration
systems for convenience store and small-box retail facilities. 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, logging, 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 CX300 with fewer capabilities and a monochrome display.

Most of the general purpose input and output commu-
nications devices required by the E2 to control refrigeration systems are connected to the E2 via the I/O Network.
The I/O Network is a simple RS485 three-wire connection
that allows data interchange between input boards (which
read sensor values and digital closures), output boards
(which carry out commands from E2’s control applications), and the E2 itself.
The I/O Network is the same thing as the COM A and
COM D Networks found on Retail Solutions’ previous
generation of controllers, REFLECS. This allows current
owners of Retail Solutions’ Refrigeration Monitor and
Control (RMC) or Refrigeration Monitor and Case Control
(RMCC) controllers to easily retrofit with an E2 RX without need for re-wiring.

1.4.2The E2 Echelon Lonworks
Network
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 controllers, rooftop HVAC controllers, and other
E2 RX and BX units — are interconnected on the Echelon
Network. These controllers do most of their own computa-

software licensing.
This section gives an overview of the E2, the hardware, and how it communicates across the I/O and Echelon Networks to control an entire system.
2.1E2 Hardware
The E2 controller is programmed to monitor and command all aspects of a refrigeration or building environmental control system. The E2 uses both an RS485 I/O
Network and a LonWorks Network to gather data from
input devices, communicate with other E2s, and activate
or deactivate loads.
In general, an E2 control network will consist of the
following components:
1.E2 - The “brain” of the control network, which
performs all necessary computations and sends
commands to the output devices that control the
system.
2.Input Boards - Transfer readings to the E2.
3.Output Boards - Banks of relays, digital pulse
outputs, or analog outputs, which the E2 may use
to control loads.
4.Smart Boards - Boards such as case controllers
(for refrigeration) or rooftop controllers (for
building control) that perform control functions
for an individual case or rooftop unit, and send
the data to the E2 for logging and alarm purposes.
5.Modem - For remote communication via phone,
if necessary .
6.Network Wiring - Wiring that connects the E2 to
other E2s, and all the input, output, and smart
boards.
7.Sensors and Loads - The “eyes” and “hands” of
the control network. Sensors “see” what needs to
be controlled on the network, and Loads are what
can be controlled, or more specifically, be turned
on and off, such as compressors, condensers,
lights, and fans.

Figure 2-6 - Gateway Board
The Gateway board is an RS485 to RS485 converter.
One side of the Gateway is always connected to the Retail
Solutions I/O Network. The other side of the Gateway is
the receiver bus (RS485). The receiver bus is connected to
one or more RS485 devices depending on which type of
Gateway is being used. The Gateway interfaces devices to
the Einstein/E2 and legacy Retail Solutions controller
(REFLECS) by simulating 16AI and 8RO boards using
Retail Solutions standard I/O board protocol. The Gateway can also convert third-party controller protocols to
Retail Solutions protocol for custom cells created in the
Einstein/E2 to interface with third-party controllers (Danfoss, Woodley , etc.).
The Gateway performs one of two basic functions:
1.It allows control of and/or status of a device using
I/O board simulation
2.Converts a third-party protocol to Retail Solutions I/O Net protocol and interfaces to a custom
cell in Einstein/E2

2.2.2MultiFlex Boards
The MultiFlex line of control system boards provides a
wide variety of input, output, and smart control solutions,
all of which are based on a single universal hardware platform. The board design uses flash-uploadable firmware
and plug-in expansion boards to configure the base platform board and apply it for use as an input board, relay
output board, analog output board, or a combination I/O
board.
2.2.2.1MultiFlex 16 Input Board
Figure 2-7 - MultiFlex 16 Input Board
The MultiFlex 16 input board offers sixteen combination analog/digital input points for use by Retail Solutions
E2, Einstein, and REFLECS control systems. The MultiFlex 16 may be used in retrofits with no additional hardware or software setup or upgrades.
The MultiFlex 16 is designed to be 100% compatible
with the previous generation of Retail Solutions input
boards (the 16AI),
via an RS485 connection to a REFLECS COM A&D Network or an E2 I/O Network. Dip switches on the board set
the network ID (board number) and baud rate.
The board also provides both +5VDC and +12VDC
output voltage points for use in powering transducers or
other input devices that require power.
The MultiFlex 16 has a Hand-held Terminal interface
Section 2.2.4, Hand-held Terminal (P/N 814-3110) that
may be used by technicians to view the input voltage and
engineering unit values for each input point without need
of a voltmeter or front panel controller display.
Table 2-6 sh ows the part number of the MultiFlex 16.
The MultiFlex 16 is designed with several features that
make it easy to install, wire, and configure. These main
user interface features are shown in Figure 2-7.
The MultiFlex combination I/O boards consist of up
to 16 combination digital/analog inputs, and a combination of relay outputs, digital outputs, and analog outputs.
