Siemens DDC 540-378 AutoZero Module 323080-701 this valve provides the preciseThe Siemens DDC 540 378 AutoZero Module is a high precision calibration component engineered for Siemens building automation systems. This module serves as the primary solution for mitigating sensor signal drift within analog input loops, ensuring that pressure and airflow transducers maintain a stable baseline. By automating the zero point adjustment, the 540 378 eliminates the need for frequent manual recalibration in VAV systems and air handling
