• Simultaneous air conditioning of wide spaces and corners is possible. Indoor units with same horsepowers can even be used in

combination.

• Master unit and slave-units can be set automatically in twin systems. No address setting is necessary.
• Multiple indoor units can be operated simultaneously with a single remote control unit. Note that individual operation is not possi-

ble.

1. Cooling capacities are based on indoor temperature of 27

°C D.B. (80.6°F D.B.), 19.0°C W.B. (66.2°F W.B.) and outdoor air

temperature of 35

°C D.B. (95°F D.B.), 24°C W.B. (75.2°F W.B.)

2. Heating capacities are based on indoor temperature of 20

°C D.B. (68°F D.B.) and outdoor air temperature of 7°C D.B. (44.6°F

D.B.), 6

°C W.B. (42.8°F W.B.)
