Model selection questions
AE-669K Mitsubishi Electric configuration questions
Does the AE-669K operating manual confirm every Mitsubishi Electric indoor unit?
No. The operating manual describes panel controls and settings. Confirm the exact Mitsubishi Electric indoor-unit model, connector, controller wiring and firmware before ordering.
Does every AE-669K version include Smart Life WiFi control?
The AE-669K-VRF-WIFI version on this page supports Smart Life app control. Confirm that exact wireless version in the quotation; the model family name alone does not establish that every supplied version includes WiFi.
Can I select the Fujitsu CN14 configuration using the AE-669K name?
No. This page concerns the Mitsubishi Electric AE-669K-VRF / AE-669K-VRF-WIFI route. The separate AE-669 Fujitsu General CN14 page describes a different selection route. Confirm the complete model, indoor-unit interface and matched firmware rather than choosing by the 669 name or panel appearance.
