A water energy source system that allows switching
between cooling and heating
The CITY MULTI WY-Series provides all the benefits of the Y-Series using water-cooled heat source units.
Heat source units can be situated indoors for greater design flexibility with no limitations on building size. Depending on
capacity, up to 50 indoor units can be connected to a single heat source unit with individualized and/or centralized
control. The two-pipe system allows all CITY MULTI units to switch between cooling and heating while maintaining a
constant indoor temperature.

Advanced water heat source unit with the benefits of the
R2-Series
The CITY MULTI WR2-Series provides all of the advantages of the R2-Series with the added benefits of a water heat
source system, making it suitable for a wider range of applications in high-rise buildings, cold climates, coastal areas,
etc.
Not only does it recover heat from the indoor units along the same 2-pipe refrigerant circuit, it also recovers heat via the
water circuit between heat source units, making it a very economical system.
