Description
The Siemens DDC 540-100-R Refurbished Terminal Box Controller manages terminal box operation by processing input signals and regulating connected control components. Internal processing circuits receive sensor data, evaluate programmed parameters, and transmit commands to adjust airflow or terminal equipment responses. Connected to sensors, actuators, communication networks, and building automation components in HVAC systems, it communicates with control systems to coordinate system operation. Programmed control sequences maintain proper equipment response, balanced airflow adjustment, and coordinated operation between connected components during operations.
