BACNet / LonWorks Interfaces

Integrated control systems that help you take advantage of the advanced functionality of an open control system

Daikin’s Open Protocol Interface devices give you the freedom to integrate your Daikin air conditioning system with the two leading Building Management Systems (BMS), BACNet and LonWorks. This means you can integrate new Daikin hardware into your existing infrastructure and take advantage of the advanced functionality and reporting available through these dedicated BMS platforms.
