INKNXSAM016O000 – KNX interface for Samsung NASA VRF systems, up to 16 indoor units

INKNXSAM016O000 – KNX interface for Samsung NASA VRF systems, up to 16 indoor units. 

The newer version of this device is IN770AIR00SO000.

The INKNXSAM016O000 IntesisBox Gateway has been specifically developed to enable reliable and efficient bidirectional integration of Samsung NASA VRF air conditioning systems with KNX automation networks. It is the ideal solution for projects requiring control of up to 16 indoor units via KNX, offering advanced functionality and simplified configuration.

The gateway is connected directly to the communication bus of the outdoor units and provides full access to monitor and control all connected indoor units. In addition to managing standard HVAC functions (on/off, setpoint, mode, fan speed), it allows reading of internal system variables such as error codes, external temperature, and operating status of the units.

All configuration is carried out using the Intesis MAPS software, which ensures intuitive setup and commissioning. With its automatic scan function, the tool detects all connected units and generates the KNX datapoints required. The embedded diagnostic features also help system integrators identify installation issues or communication faults.
