[SCS Controller - General information](https://support.aofrio.com/iot-hardware?hsLang=en#scs-controller-general-information) January 15, 2026 # SCS Controller overview ## Find out about AoFrio’s intelligent refrigeration controller series, SCS SCS stands for Smart Cooling Solution. The AoFrio SCS range is a family of intelligent electronic controllers for commercial refrigeration systems. They feature: - Advanced refrigeration control capability - User friendly interfaces - Connection to AoFrio’s revolutionary online fleet management software. The SCS Controller is available in different formats to suit your precise application. It can also be used as an unconnected electronic controller for the replacement of mechanical thermostats. Many OEMs fit the SCS on their production lines using our range of specialized programming cradles and software. The controller has no audible alarm but one of the outputs can be configured to support an external sound alarm if needed. SCS Controllers can be used in any refrigeration equipment, new or retrofit. Customers who are looking to easily connect their existing fleet may benefit from using our sensor – the AoFrio Monitor. Its easy installation method makes it a perfect fit for field deployment and connection to an IoT ecosystem including the SCS controller and other AoFrio technologies. ![SCS Controller](https://support.aofrio.com/hs-fs/hubfs/SCS00111.jpg?width=670&height=447&name=SCS00111.jpg) *(Pictured: SCS 600)*  -
