6.18 REMOTE DUAL TEMPERATURE WITH CIRCUIT EEPR – CONFIGURATION R
The S3C case controller is capable of controlling and monitoring dual temperature, single evaporator refrigerated fixtures
installed as a line-up. The case shown in the diagram below is the lead case of the line-up. In this scenario, one S3C case controller
is required. The S3C case controller will control all case functions as well as take all the desired sensor inputs for one evaporator
and drive the EEPR. The typical control method is to regulate the average discharge air temperature with the EEPR while allowing
the TEV to control superheat. Note that the required liquid line solenoid (LLS) may be installed as one-per-case or one-per-line-
up. In addition, only one case in the line-up (lead case) needs an EEPR connected to the S3C case controller. Case numbers 2,
3, 4,…n will require their own S3C case controller but will not have an EEPR connected to them if they share a common suction
line with the lead case shown in the diagram below. The case is toggled between its two operating temperatures either via the
building automation system (BAS) or with a locally installed physical switch. When the case controller receives a command to
change temperature, the EEPR will either open or close to lower or raise the case temperature, respectively.
To configure the S3C control package for configuration R
shown above, follow these directions:
If the controller has not been factory set, then upon initial
start-up, the controller will be in set-up mode and the screen
will display
 (for self-contained case).
1. Press the
SET
button, then use
▲▼
buttons to scroll
to o ; press
SET.
This will configure the controller to
support a remote case.
2. Press the
SET
button when  (Rack Identifier)
is displayed. Use the ▲▼ buttons to configure the 4
character Rack Identifier.
Note: Push
▲
button for
numeric,
▼
for alpha characters.
When satisfied
with each digit, press the
SET
button to go to the next
digit. Pressing
SET
multiple times will move to the next
parameter.
3. Press the
SET
button when
ud
(Line-up Identifier)
is displayed. Use the
▲▼
buttons to configure the 4
character Line-up Identifier.
Note: Push
▲
button for
numeric,
▼
for alpha characters.
When satisfied
with each digit, press the
SET
button to go to the next
digit. Pressing
SET
multiple times will move to the next
parameter.
4. Press the
SET
button when
d
(Case Identifier)
is displayed. Use the
▲▼
buttons to configure the 4
character Case Identifier.
Note: Push
▲
button for
numeric,
▼
for alpha characters.
When satisfied
with each digit, press the
SET
button to go to the next
digit. Pressing
SET
multiple times will move to the next
parameter.
5. Press the
SET
button when  (Application Type) is
displayed. Use the
▲
button and scroll to du (Dual
Temperature Case); press
SET.
6. Press the
SET
button when  (Local Stepper Valve
Configuration) is displayed. Use the
▲
button to scroll to
 (Electronic Evaporator Pressure Regulator); press
SET.
This is the valve that is attached to the main S3C
Case Controller.
7. Press the
SET
button when  (Expansion Valve Type)
is displayed. Use ▲▼ buttons to choose the Expansion
Valve Type based on the below chart; press
SET.
8. Press the
SET
button when  (Building Automation
System Expected) is displayed. Use the ▲▼ buttons to
choose
