The Interra ITR830-0012 connects Gree split air conditioners to KNX for bidirectional monitoring and control of operating parameters. It suits residential and light commercial projects where Gree indoor units must join a KNX BMS or hotel GRMS backbone.

Mount inside the indoor unit or remotely; one port to the Gree communication bus, one to KNX. 4 logic gates and 8 converters implement occupancy-based shutdown, temperature limits, and scenes. With no wired remote, the gateway acts as master; with a Gree wired remote, master/slave roles are set in ETS.

Key Features — Gree Split on KNX

• Compatibility: Gree split models per Interra compatibility list.
• Logic and converters: On-board energy and scene automation.
• Fault reporting: Exception errors forwarded on KNX.
• Compact module: 88 × 62 × 27 mm; KNX bus-powered (~5 mA).

Applications and KNX Integration

• Residential multi-split: One gateway per addressed indoor unit (per ETS design).
• VRF projects: Use ITR830-0013 Midea or ITR830-0006 LG instead of split SKU.
• Room control: iX2 / iX3 thermostat pages.

Choosing Interra AC Gateways

ITR830-0012 is for Gree split systems only. Verify models in the compatibility PDF; ambient temperature from KNX bus is restricted when the gateway shares the bus as slave with a Gree wired remote (see product manual).
