phase heat pump system perfect for light
commercial or large residential applica-
tions. Available in 36,000 or 48,000 Btu/h,
the S-Series can provide cooling or heating
for up to eight individual zones.
The CITY MULTI S-Series for homes and
small offices offers all the features and

features a single-phase outdoor unit with
Variable Refrigerant Flow Zoning (VRFZ) technology and
CITY MULTI Controls Network (CMCN) to cool or heat all zones
with a variety of indoor unit styles. The compact outdoor unit
utilizes R410A refrigerant and an INVERTER-driven compressor to
use energy effectively. A maximum of eight CITY MULTI indoor units
can be connected with up to 130% connected capacity, depending
on diversity. CITY MULTI Controls Network intelligently manages the
CITY MULTI building comfort solution through zone controllers and
system controllers and optionally through a networked PC to
manage individual comfort and to provide the ultimate
building comfort solution.

is easy to install and can
be accessed for service
through both a front and
side panel. The unit’s
compact dimensions and

Blue Fin treatment
The standard anti-corrosion Blue Fin treatment of the heat
exchanger is especially effective in protecting the aluminum
fins from pollution damage,
such as smog and environ-
mental pollens, which
reduce the capacity and
life expectancy of the unit.
All CITY MULTI R410A
outdoor units have been
treated with Blue Fin
prior to leaving the factory.
Additional protection of the frame and other component
materials on all outdoor units is available as an option, as
indicated on the model suffix number with a ‘-BS’.
