Product FAQ
AE-5509-VRF selection questions
Is AE-5509-VRF compatible with every unit from the listed brands?
No. The brand list is a starting point for project matching. Confirm the full indoor-unit model, physical interface, original controller arrangement and matched hardware/firmware. The straight TFT display does not establish protocol compatibility.
Why does the AE-5509-VRF manual cover name AE-6609-VRF?
The existing series clarification states that corresponding 55 and 66 models share functions, electrical specifications and wiring. The 55 series uses a plastic enclosure, while the 66 series uses aluminium alloy. Use the AE-6609-VRF manual within that scope and match the ordered terminal diagram.
Do WiFi, Zigbee and Tuya mean all wireless options are included together?
No. Confirm the required wireless module, app or gateway and supported controls for the ordered AE-5509-VRF. A list of options does not establish simultaneous WiFi and Zigbee or identical functions for every indoor unit.
