The Interra ITR830-0004 integrates Mitsubishi Heavy Industries air conditioners with KNX for complete bidirectional monitoring and control. The gateway connects to the indoor unit wired-remote bus and the KNX line, reporting modes, setpoints, fan speeds, and fault codes to the building network.

Installation is typically inside the indoor unit or in a nearby enclosure. 3 digital inputs accept window contacts, occupancy sensors, or other binary devices for interlocks. Ambient temperature can be taken from the gateway sensor input or a KNX temperature object. 4 logic gates and 8 converters enable energy-saving scenes and temperature limits in ETS.
