Does it work without an HVAC system?

It is built to connect to ductwork and push scent through the air handling system. Without ducts it can still mist from the outlet, but it won't cover a large space the way a ducted install does.

How is it controlled?

Controls are on the touch panel below the display, and the smart features allow scheduling and remote adjustment. Setup is done through the app.

What kind of fragrance does it use?

It uses liquid fragrance oil made for HVAC or commercial diffusers, not candles or wax melts. Use oils meant for cold mist diffusion.

Where should it be mounted?

Mount it on a wall near the duct connection, with the mist outlet feeding into the airflow. Keep it out of reach of children and away from direct moisture.

How does it compare with a plug-in diffuser?

A plug-in covers one room and needs refilling often. This unit scents a whole ducted space on a schedule, but costs more and needs installation.
