Siemens controllers for VAV systems

Siemens, VAV, air conditioning, BMS, BEMS, building management systems

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.
