Product FAQ
AE-740-VRF selection questions
Does the linked manual specifically name AE-740-VRF?
The linked PDF cover names AE-740K-VRF / AE-740K-VRF-WIFI. Treat it as a reference until applicability to the ordered AE-740-VRF is confirmed. Request the matching firmware details and wiring diagram before installation.
Does the AE-740K reference prove compatibility with every listed VRF brand?
No. Its wiring illustration labels terminals N/P2 and P/P1; those labels do not establish compatibility with every indoor unit or interface. Send the AC brand, full indoor-unit model and existing controller terminal photos for a model-specific check.
Does every AE-740-VRF configuration include WiFi or Zigbee?
Confirm the wireless version in the quotation. The reference cover identifies a WIFI variant, which does not establish that every AE-740-VRF has WiFi or Zigbee. Also confirm supported modes, fan speeds and app or gateway requirements for the matched indoor unit and firmware.
