Cooling/heating changeover system with horizontal airflow for
small offices and stores
The CITY MULTI S-Series (for small applications) makes use of a two-pipe refrigerant system, which allows for system
changeover from cooling to heating, ensuring that a constant indoor climate is maintained in all zones. The compact
outdoor unit utilizes R410A refrigerant and an inverter-driven compressor for effective energy use.
With a wide lineup of indoor units connected to a flexible piping system, the CITY MULTI Series can be configured to suit
diverse applications. Thanks to the individual operation of up to 12 units* and a group change function, the CITY MULTI
S-Series can flexibly accommodate layout changes in stores and offices.
