Refrigerant: R-410A

No Branch Boxes Required: While the 8 Zone AOU48RLXFZ requires branch boxes and separation tubes, the AOU18, 24 and AOU36RLXFZ do not.

Connectable Capacity: Increases combinations and flexibility. See chart below. All indoor units can operate at once, how ever if all the evaporators are calling for cooling or heating at the same time it will decrease the capacity of each evaporator not to exceed the condenser’s capacity. As zones meet desired set point the system’s other evaporators increase output up to the evaporator’s rated capacity.

Inverter Compressor: Variable speed compressor provides a range of capacity.

Moderate Low Ambient Operation: This additional feature allows the systems to operate indoors, even when outdoor ambient temperatures are 14°F (AOU18,24RLXFZ), 32°F (AOU36RLXFZ) in cooling mode and 5°F, (AOU18,24RLXFZ), 14°F (AOU36RLXFZ) in heating mode, without any additional accessory.
