The S3C family of controls includes a case controller, display module, and valve module that all support open protocol communication via BACnet and Modbus. The system is designed to facilitate both installation and integration by the refrigerated appliance OEMs as well as retrofit into existing supermarket refrigeration control installations. When enabled, the controller provides automated configuration and network integration. The S3C Case Control peer to peer system is capable of standalone or BAS coordinated control of up to 8 refrigerated cases per lineup. This family of controls simplifies and shortens the time required to set up new equipment or retrofit an existing system for more precise control.
