every inch of the room.
Double Twin Multi operation
4 indoor units can be run simultaneously
with a single outdoor unit.
Improved comfort level and space-saving
for outdoor unit installation
Required about 40% less installation space
for outdoor unit
4 indoor units distribute comfortable airflow
throughout the room.
Simultaneous operation of four indoor units
can be controlled from a single remote controller.
Requires a single refrigerant piping system.
Triple Multi operation Twin Multi operation
Indoor units include ceiling mounted cassette type, ceiling suspended type, and duct connection middle and low static pressure type.
