Units are available
in single-zone and
multi-zone versions
With single-zone equipment, one outdoor unit
connects to one indoor unit (see pages 18-25 for
indoor units available). This option is ideal if you only
need cooling and heating in a single space.
With multi-zone equipment, one outdoor unit can
connect up to eight indoor units. This option is perfect
if you need cooling and heating in multiple spaces
with different functions, such as a nursery versus a
kitchen or an office versus a conference room.
Each zone is served by its own indoor unit. Indoor
units come in a variety of forms including wall-
mounted units, floor-mounted units, ceiling cassettes
and air handlers.
Wall-mounted units tend to be the most popular, but a
floor-mounted unit could be an attractive option for a
sun room that has windows, but no wall space. A high-
performance air handler could replace an older system,
such as a central system or boiler that previously
cooled or heated an open space.
