About this part

The SIEMENS 550-405 ATEC VAV 24V 50/60Hz is a versatile control designed for HVAC systems. With a voltage of 24V and a frequency of 50/60Hz, this product is suitable for various industrial and commercial applications. The VAV control technology allows for efficient and precise regulation of heating and cooling systems, while the Siemens brand ensures reliability and quality. Perfect for managing temperature and ventilation in a range of environments, this model is a valuable addition to any HVAC setup.

The Siemens 550-405 is an ATEC VAV controller for HVAC systems, running on 24 V at 50/60 Hz. A VAV controller positions the damper in a variable air volume box to hold the airflow and temperature a zone needs. It is replaced when it stops responding, loses communication, or no longer drives the damper.

Before you order: confirm 550-405 against your current controller, check that your box has a 24 V supply, and expect to set up or program the controller for your building system.
