Start here to confirm the indoor-unit model, CN14 control-board interface and suitable ACMELEC thermostat panel before opening a model detail page.
No separate power supply or gateway is required for the illustrated connection. Verify the indoor-unit model first.
This brand selection page explains the Fujitsu General and O General compatibility route. AE-669 is the primary verified CN14 model, while other panel options require project-specific wiring and firmware confirmation.
For Fujitsu General and O General projects, first confirm the complete indoor-unit model and the CN14 connector. Then compare the available panel style, smart-control configuration and OEM requirements. For the exact AE-669 specifications, installation diagram and manual, continue to the dedicated AE-669 model page.
