this pressure reducing station combines a high-flow regulator with a 5-micron particulate filter and a mechanical automatic drain valve

Standard 115V or higher amperage 20A units will require different specifications

allowing contractors to maintain tight system tolerances

Using a lower voltage motor on a 277V line will result in immediate winding failure

Factory-Programmed Logic: Ensures precise HVAC blower motor torque and speed ramping for optimized system performance

Siemens DDC 540-110N Controller 328140-751 this pressure reducing station combinesThe Siemens DDC 540 110N Controller is a high performance Terminal Equipment Controller (TEC) engineered for precise management of HVAC zone control applications. As the direct 540 110 cross reference, this digital module is purpose built for fan coil unit control, heat pumps, and unit ventilators within a Siemens APOGEE FLN network. Operating on a 24 VAC power supply, it utilizes advanced PID algorithms to stabilize temperature loops and minimize
