The Interra ITR830-0013 is a Midea VRF AC KNX gateway for bidirectional monitoring and control of Midea indoor units over the KNX bus. It connects to the indoor unit communication port on one side and the KNX line on the other, enabling mode, setpoint, fan speed, and fault feedback in hotel GRMS and commercial BMS projects.

Compatible models are listed in Interra’s VRF compatibility list (see Downloads). The gateway mounts inside the indoor unit or remotely. It can run standalone or alongside a Midea wired remote with master/slave role selection in ETS. On-board 4 logic gates (AND/OR/XOR, up to 4 inputs each) and 8 converters (four math operations) support energy routines, scenes, and temperature limits without extra bus devices.
