Emerson E2 Manuel D’Utilisation

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-
tion and system control, but they communicate with other 
E2s to provide logging, alarm control, and other functions. 
In addition to these, Emerson Retail Solutions also offers 
Echelon-compatible input and output boards similar to 
those available for the RS485 Network.

Figure 1-3 shows the E2 RX peripherals that commu-

nicate across the Echelon Network:

• CC-100 - Case control board - controls all lights, 

fans, defrost, and refrigeration for a single case. The 
CC-100 controls pulse or stepper valves to provide 
precise evaporator control, resulting in better tem-
perature maintenance and energy efficiency.

• ESR8 - Evaporator stepper regulator - the analog 

outputs on this board allow the E2 to control circuit 
temperature in up to eight circuits using suction-

side mounted electronic evaporator pressure regula-
tors (EEPRs).

• TD3 - Temperature display - has three inputs that 

monitor case temperature, product temperature and 
defrost status. 

• Third Party Echelon Devices - Echelon

 devices communicate with E2 through its 

“Open Echelon” networking feature, and require a 
license key and a description file that is loaded into 
the E2 that enables communication.

In large installations where more than one refrigeration 

system is present, or where E2s are controlling both refrig-
eration and building HVAC systems in the same site, the 
E2s share information with each other across either the 
Echelon Network or via Ethernet.
