5.26 Standard Circuits
Refrigerated cases that do not use case controllers are
controlled by Standard Circuit applications. In a Standard
Circuit application, the Site Supervisor is responsible for
all case monitoring and control; it uses the RS485 I/O Net-
work to both gather case temperature inputs and activate
or deactivate the liquid line solenoids, defrost modes, and
fans. Also, circuits that use ESR8s and MultiFlex ESRs
are controlled using Standard Circuits.
The Standard Circuits application provides supervisory
control of controllers. It keeps the temperature setpoint
and other basic configuration parameters synchronized
across all associated devices.
How To Add a Standard Circuits Device on the Site
Supervisor:
1. From the Home screen, navigate to Main Menu>
Summaries and Floor Plans> Site Summaries>
Refrigeration, click the screen drop-down arrow
on the upper right of the screen, click
Add
Controls
.
2. Select the Control or Application Type -
Circuits (Standard)
, enter the Quantity, Control
Name and Serial Type. Note that Serial Type
information can be enter later. Click
Save
to add
the application.
3. A Confirmation box will appear saying that the
application is successfully added to the system,
click
Close
or
Edit these controls
.
4. The system will display the new application(s) on
the Site Summary screen.
5. Click the Standard Circuits application panel box
to view the application.
6. The system will display the Standard Circuits
application parameters.
7. The user can view and configure the properties of
the application by setting the Edit Mode to
ON
on the screen drop-down arrow on the upper right
of the screen.
Licensing:
The maximum number of Standard Circuit
applications that can be licensed is 48.

5.27 Case Control Circuits
5.27.1 Overview
Case circuits that use CC-100s, CS-100s, EC-2s, or
CCBs for case control rely on Case Circuit Control appli-
cations in the Site Supervisor to provide them the neces-
sary setpoints, defrost scheduling, and other control
parameters. Unlike Standard Circuit applications, Case
Control Circuits do not directly control temperature in the
case circuits; instead, the case controller controls tempera-
ture for each individual case based on the setpoint(s) sup-
plied to them by their associated Site Supervisors.
Setup of a case-controlled refrigerated case system is a
two-fold process:
1. For each case circuit in the refrigeration system, a
separate Case Control Circuit application is cre-
ated with its own set of control parameters.
2. Each CC-100, CS-100, EC-2, and CCB is
associ-
ated
with a Case Control Circuit application in
the Site Supervisor. Association creates a net-
work link between the case controller and the
application which supplies the information neces-
sary to control temperature, defrost, lights, fans,
and anti-sweat heaters.
This section of the manual covers both the program-
ming of a Case Circuit Control application and the process
of associating a CC-100, CS-100, EC-2, or CCB with a
Case Circuit Control application.
NOTE: Do not set up a Standard Circuit
application for a case that uses a CC-100 or
CCB case controller. These cases must use
Case Circuit Control applications.
