The Siemens switching and monitoring device designed for efficient control and monitoring of heating, ventilation, and refrigeration systems. With its various switching and monitoring functions, it offers extensive configuration options and can be used for lead/lag control of pumps, fans, motors, and refrigeration machines. The device features 3 universal controllers with limiting function and offers data acquisition options such as pulse count and operating hours counting. It is modular extendable with extension modules for additional inputs and outputs. The device also supports menu-driven operation with a separate operator unit and KNX bus connection for operation and process information.
