Siemens has expanded its environmental product portfolio with two OpenAir air volume controllers that have been developed by the Building Technologies Division of Siemens. Using a bus protocol plug-n-play PL-Link and KNX standard, the controllers have communication capability which allow them to support advance functions.
The GLB181.E/KN and the GDB181.1E/KN are two networkable controllers which have been added to the range of OpenAir controllers, both available in both LTE mode and S mode.
Designed to support Siemens’ KNX standard as well as PL-Link, the advanced communication capabilities in the compact controllers enable the devices to support energy-efficient tasks including demand-based control required for the central air handling. The KNX LTE and PL-Link facilitate commissioning and configuration whereas the KNX S mode aids in easy integration into 3rd party systems as well as custom device programming. The devices feature a very stable and highly accurate differential pressure sensor that allows the two controllers to achieve unparalleled control performance.
Siemens will introduce two non-networkable controllers along with a modular air volume controller devoid of an actuator. The existing GLB181.1E/3 and GDB181.1E/3 non-networkable compact controllers have been completely redesigned and equipped with precise mechanics and differential pressure sensor.
The simplified commissioning and configuration of the networkable OpenAir devices allows building operators to lower costs. The newly developed air volume controllers can be easily calibrated for the VAV box since parameters of just three OEM-specific devices need to be provided. Additional flexibility is also provided by the networkable compact controllers due to adaptive mode for rotation. IP54-compliant, the air volume controllers offer extended stability without temperature drift or aging.
