What is the BTL Working Group?
The working group was formed by BACnet International to oversee the establishment of the BACnet® conformance certification and listing program. The working group is comprised of members of BACnet® International and BIG-EU whose goals are to promote and maintain the BACnet® and BTL® trademark.
The BACnet Testing Laboratories Working Group provides oversight and guidance to the BACnet Testing Laboratories (BTL). The BTL Working Group is responsible for the technical aspects of BACnet International’s testing and listing activities, the central goal of which is to improve BACnet interoperability between building automation products.
The devices listed were tested by a recognized BACnet® Testing Laboratory. All tests required to obtain a BTL Mark are posted in detail next to the listed device. Devices that implement all of the required capabilities for a particular profile are listed under that profile or a profile of lower capability depending on the designed use for the device. Devices may provide additional capabilities for the listed profile. The actual capabilities shall be listed in the PICS for the device. When looking for a particular type of device, check the functionality of a variety of profiles. Different vendors may implement them under different profiles. For example, a VAV controller may be listed under a B-ASC or B-AAC profile. A communicating thermostat device may be listed under a B-ASC or a B-SS device. Currently, the BTL Product Listings contains 660 active products from 112 distinct manufacturers.
