floor managers of alarms and notices. Other lights on the
display show the ON/OFF status of refrigeration, defrost,
and fans.
The EC-2 can be easily programmed using either the
four front-panel buttons or an optional infrared remote
control. For security, the buttons can be disabled to prevent
tampering.
NOTE: There are several variations of the
EC-2. Contact Retail Solutions at 1-800-829-

2.3.4 CC-100 Case Controllers and
CS-100 Case Circuit Controllers
A CC-100 case control board is a “smart” board capable
of controlling all functions for a single case, including
lights, fans, defrost, anti-sweat, and suction side or liquid
side valve control. CC-100s perform these functions independently
from the E2 RX controllers, but it does rely on a
parent E2 for logging, alarming, providing supplemental I/
O values, and coordinating defrost times among circuits.
There are four different models of the CC-100, each of
which controls a different type of valve.
1. CC-100P (P/N 810-3160)— Case controller for
liquid-side pulse valves (also called electronic
expansion valves, or EEVs). This model is capable
of controlling up to two pulse valves simultaneously
(for use in dual-evaporator applications
such as walk-in boxes).
2. CC-100LS (P/N 810-3170) — Case controller for
liquid-side stepper valves (EEVs).
3. CS-100 (P/N 810-3177) — Case circuit controller
for suction-side stepper valves (also called electronic
evaporator pressure regulators, or EEPRs).
4. CC-100H (P/N 810-3171)— A special version of
the CC-100 that is used by a particular manufacturer.
This board controls temperature in a case
using suction-side stepper valves that regulate
pressure in the evaporator.
The CC-100/CS-100 board is shown in Figure 2-20.

2.3.5 The ESR8 (Discontinued)
The ESR8 electronic suction regulator (P/N 810-3195)
is an Echelon Network-based control board that controls
up to eight separate electronic suction regulator (ESR)
stepper valves. The ESR8 uses suction-side variable position
ESRs to vary evaporator pressure and control temperature
for an entire circuit. The ESR8 offers an economical,
more efficient alternative to TXV control.
The board can be used with either Emerson Flow Controls
ESR12 or ESR20 valves as well as a number of commercially
available ESR stepper valves. Note that
Emerson Flow Controls supplies both a 24 Volt and a 12
Volt version of the valve. The ESR board is only compatible
with the 12 Volt version of the valve.
The board features two LEDs for each valve which
indicate movement and direction. A status LED indicates
the general status of the board.
The ESR8 board is shown in Figure 2-21.
