INKNXHAI064C000 – Haier VRF to KNX Gateway 64 Indoor Units

INKNXHAI064C000 – Haier VRF to KNX Gateway 64 Indoor Units. 

The INKNXHAI064C000 interface from Intesis is an industrial-grade gateway that brings full, bidirectional integration between Haier VRF and commercial line air-conditioning systems and the KNX building-automation world. Supporting up to 64 indoor units per gateway, it is ideal for large-scale projects such as hotels, office towers, hospitals, campuses, or multi-tenant residential complexes where energy efficiency, comfort and centralized control are crucial success factors.

Connected directly to the Haier indoor unit communication bus, the module allows building-management platforms to read and write every essential HVAC parameter: operating mode, temperature set-point, fan speed, swing position and more. In the opposite direction, the gateway securely forwards fault codes, alarms and maintenance counters back to KNX, giving facility managers instant diagnostics and the ability to launch preventive maintenance before comfort is compromised.

Commissioning is straightforward with ETS: simply import the product database, drag-and-drop the channel templates and assign the desired KNX datapoint types (DPT-1.x, 5.x, 9.x, 20.x, 24.x etc.). Because the gateway is KNX-certified, you can trust seamless interoperability with any third-party KNX thermostat, touchscreen or logic controller on the market. Thanks to intuitive parameterisation, integrators can finish a 64-unit mapping in minutes rather than hours, dramatically reducing on-site costs.

Key advantages at a glance:

• 64 indoor units per gateway – scale up without adding extra hardware.
• 4 potential-free binary inputs that accept window contacts, occupancy sensors or dry-contact switches to trigger open-window, presence or timeout energy-saving logics.
• Simultaneous IR/RCU and KNX control – end-users keep their familiar remote while the BMS remains master.
• Scene memory (5 presets): store and recall “Night”, “Eco”, “Cleaning”, or “Meeting” scenarios instantly from any KNX pushbutton.
• Compact enclosure 70 × 70 × 28 mm – slips inside ceiling-mounted cassettes or fan-coil housings.
• 2-level galvanic isolation between KNX TP1 and Haier electronics ensures long-term reliability.
• Firmware upgradeable via USB, protecting your investment against future protocol changes.

Technical specifications:

• KNX port: 1 × KNX TP1 (opto-isolated), plug-in screw terminal.
