Zone-specific airflow routing is the ability of a multi-head system to direct air specifically where it is most needed within a room. This is perfected in our Ceiling Cassette Multi-Zone units, which feature four-way directional louvers. For large bedrooms, the Bravo Milano 18,000 BTU Universal Floor/Ceiling allows for vertical and horizontal swing adjustments. In a Tri-Zone configuration, each user can set their own preferred airflow pattern without affecting others. To maintain the efficiency of this routing, ensure the line sets are properly insulated using materials from our Installation Kits. This level of control prevents uncomfortable drafts and ensures even temperature distribution throughout the space. It is a key factor in the high comfort ratings of the Multi-Zone series.
