INKNXSAM064O000 – Samsung NASA VRF to KNX Gateway for up to 64 Indoor Units

INKNXSAM064O000 – Samsung NASA VRF to KNX Gateway for up to 64 Indoor Units. 

The newer version of this device is IN770AIR00MO000.

The INKNXSAM064O000 gateway has been specially designed to provide seamless and fully bidirectional integration between Samsung NASA VRF systems and KNX TP networks. Developed by Intesis, this robust gateway supports up to 64 indoor units, allowing centralized HVAC control and monitoring directly from a KNX installation.

It connects directly to the communication bus of the Samsung outdoor units and enables interaction with all connected indoor units. This allows complete access to core AC functions (on/off, setpoint, mode, fan speed, swing) as well as to internal parameters like alarms, statuses, and system diagnostics – significantly enhancing building management system (BMS) visibility.

Configuration is done via the intuitive Intesis MAPS software, which simplifies integration and setup through features like automatic scan of connected units, graphical mapping of KNX objects, and built-in diagnostics. The gateway can be up and running within minutes, significantly reducing engineering time. Additionally, the gateway supports firmware upgrades and status monitoring via Ethernet and serial console.
