Siemens controllers for VAV systems
Published: 05 May, 2016
Siemens Building Technologies has added four controllers for VAV (variable air volume) systems to its OpenAir range, along with a robust handheld operating unit. The new products are aimed firmly at the VAV market and support all major communications protocols — including KNX, BACnet and Modbus. They therefore integrate seamlessly into any application and system, including those from third-party vendors.
A bus connection eliminates the need for point-to-point wiring in large installations. Number- and colour-coded cables and marked connection nozzles for pressure tubes further simplify installation.
The AS20 handheld operating unit for all Siemens VAV controllers has a user-friendly display and intuitive menu guidance to make commissioning and operation easier.For more information on this story, click here: May 2016, 84
