The multiple piping of Multi F systems can support two, three or four indoor units that are typically mounted in separate rooms. Compact
refrigerant pipes work in tandem with wiring to link the outdoor unit with all indoor units directly. Most indoor units include its own remote
control, allowing the user to set the temperature individually in different rooms. The indoor units are available in a variety of capacities and
styles, including Art Cool™ Mirror and Gallery Wall Mounts, Standard Wall Mount, Four-Way Ceiling Cassette, Horizontal Ceiling Concealed
Duct, and Vertical-Horizontal Air Handling models.
