The Siemens thermal drive actuator designed for controlling electro-thermal actuators in heating or cooling systems. It is a reliable and efficient solution for building automation, offering noiseless control of AC 24 V or AC 230 V actuators. The maintenance-free terminals allow for easy connection and looping through various types of conductors. The actuator features built-in device for installation in an automation module box AP 118 or room automation module box AP 641, providing flexibility in system integration. With configuration options in the ETS, it offers priority control of security and override functions, automatic or demand-based valve flushing, and extensive room temperature and ventilation control capabilities. It also supports interaction with primary systems for heating or cooling demand and demand-based pump control.
