INKNXSAM008O000 – KNX interface for Samsung NASA VRF systems, up to 8 indoor units

INKNXSAM008O000 – KNX interface for Samsung NASA VRF systems, up to 8 indoor units. 

The newer version of this device is IN770AIR00SO000.

The INKNXSAM008O000 Intesis gateway is a reliable and industrial-grade communication interface designed to enable seamless integration of Samsung NASA VRF air conditioning systems into KNX building automation environments. Supporting up to 8 indoor units, this solution offers full bidirectional communication to control and monitor key HVAC parameters.

Directly connected to the outdoor unit communication bus, the gateway enables centralized control of all indoor units through the KNX system. This includes main functions like On/Off, temperature setpoints, fan speed, operating mode, as well as access to extended data points such as error codes or internal operating values of outdoor units. It is particularly suited for projects that demand integration with home or building management systems.

Configuration is carried out via the intuitive Intesis MAPS software. This tool allows you to define all communication parameters, scan and detect available indoor units automatically, and diagnose errors in real-time using powerful diagnostic features. These advanced tools reduce commissioning time and help ensure long-term system reliability.
