INKNXTOS016O000 – Toshiba TCC-Link to KNX Gateway for 16 Indoor VRF Units

Toshiba VRF TCC-Link to KNX Interface (up to 16 indoor units). 

The INKNXTOS016O000 is a dedicated communication gateway designed for bi-directional integration of Toshiba VRF systems (via the TCC-Link bus) with KNX installations. It enables precise control and monitoring of each connected indoor unit directly from KNX keypads, touch panels, room controllers, or a higher-level BMS. This version supports up to 16 indoor units, making it a strong fit for apartments, offices, retail spaces, and compact commercial buildings where scalable HVAC control is required.

The gateway operates as a plug & play device using the TCC-Link port for direct connection to the Toshiba VRF network. KNX communication is handled through an opto-isolated KNX TP1 port, improving electrical robustness and helping protect both networks. Integrated LED indicators and the KNX programming button make commissioning and troubleshooting faster on site.

With ETS-based setup and a ready product database, INKNXTOS016O000 integrates cleanly into KNX logic: room comfort automation, schedules, energy-saving modes, and occupancy scenarios can be built around HVAC operation. Thanks to broad support of KNX DPT datapoints, the gateway ensures interoperability with KNX devices from different manufacturers, keeping project design flexible and future-proof.
