Advent AAC Non-Ducted Ceiling Assembly | AACNDC | Mechanical Controls

The ceiling unit for a single-room Advent install. The ASA Electronics AACNDC Non-Ducted Ceiling Assembly mounts under the rooftop unit and blows conditioned air directly into the room through its own louvers, with mechanical knobs and a built-in thermostat — no wall control needed.
