  • Description

    Panasonic 4-Zone Mini Split now has heating capabilities down to -5°F, making it a great option for much of the US.

    Panasonic's 4 Zone Mini Split System offers you the advantage of a single system that is connectable for up to 4 indoor units. That is from 2 up to 4 individual temperature controlled rooms without duct work! Panasonic's innovative technology enables high energy saving performance with SEER ratings of 22 and an HSPF rating of 9.5 - for more efficient operation than ever before. Because each room operates independently, you can customize your BTUs for each space. Panasonic offers Indoor units ranging from 5500 BTUs for smaller rooms, up to 18,000 BTUs for larger rooms. When the CU-4E24RBU-5 is installed with non-ducted indoor units, it is an Energy Star Qualified system!

    With the Panasonic System 4 Multi-Zone, long piping length flexibility is also featured. The maximum total length is 230 feet with a maximum length of 82 feet for a single indoor unit The maximum height difference is 49 feet. With the flexibility of long piping lengths, this system can be installed in virtually any building design.

    Of course the system also includes Panasonic's inverter technology - providing superb comfort, precise control and extremely efficient operation by constantly adjusting the power supply frequency. The result is speedy, flexible operation that uses less electricity. The inverter constantly adjusts the compressor rotation speed to provide optimum performance at all times. Once the set temperature is achieved, the inverter air conditioner continues to operate with minimum power. Switching from the cooling mode to the heating mode is done easily with the simple push of a button on the remote!

    And talk about reliability, with its low ambient heating capability, you will never be cold - heating is possible even if the temperature outside falls as low as -5°F.

    The CU-4E24RBU-5 Quad-Zone is rated for 24,000 BTU Cooling Capacity and must be connected to at least two / maximum four indoor units. The combined BTU ratings of the units chosen can total up to a maximum connected BTU rating of 30,600 BTUs.
