Outdoor Unit BTU/h
Indoor Units Sizes Learn More Mini split systems can have one or more indoor units connected to a single outdoor unit. Indoor Unit Size(s) specifies what indoor unit sizes are used in a system. For example (9k + 12k) means the system includes a 9k BTU unit and a 12k BTU unit.
Hyper-Heating Learn More Certain mini split systems have the ability to produce heat at lower outdoor temperatures than standard systems. Mini split systems with hyper-heating technology are also able to heat with 100% capacity at lower outdoor temperatures compared to standard systems.

Features
    Mitsubishi's dedication to new technology means that multi-zone mini split systems are now a year-round comfort solution for homes in freezing climates. This low ambient system uses a hyper-heating H2i MXZ-4C36NAHZ outdoor condenser to provide efficient cooling and subzero heating through three advanced MSZ-FH wall mounted indoor units. These indoor units feature Mitsubishi's i-See sensor, which automatically detects where heating or cooling is needed. Three wireless remote controllers guarantee convenient comfort by allowing you to control the temperature in individual rooms. With multiple operating modes, multiple fan speeds, and multiple airflow directions, this is a system that fits the needs of nearly any home.
  • H2i Technology
  • Low and negative ambient temperatures don't bother the MXZ-4C36NAHZ. It is rated for 100% heating capacity at 5 degrees F and continues to provide heating in outdoor conditions as low as -13 degrees F.
  • Integrated Base Pan Heater
  • MXZ-C outdoor condensers have a factory-installed base pan heater in the drain pan. This prevents condensate from freezing and damaging the unit in frigid climates.
  • Precision Temperature Control Technology
  • This outdoor condenser is equipped with inverter technology and an electronic linear expansion valve. By adjusting compressor speed and refrigerant flow, these components provide precise temperature control and incredible efficiency.
  • i-see Sensor
  • Each MSZ-FH has an i-see Sensor 3D that monitors its zone for changes in temperature. If an underserved area is detected, an MSZ-FH will temporarily direct airflow to that zone. It also enters energy saving mode if no human heat signatures are detected.
  • Hot-Start
  • Mitsubishi's hot start technology prevents cold drafts by delaying indoor unit fan operation until the heat exchanger has warmed up.
  • Advanced Filtration System
  • With three unique filters inside the MSZ-FH indoor units, the air in your zones is not only being conditioned, but it is also actively being cleaned. These filters remove odors, nanoparticles, and bacteria from re-entering your home.
  • Smart Set
  • Mitsubishi's Smart Set function allows you to save a cooling and heating profile consisting of a temperature, a fan speed, and an airflow direction for each indoor unit. These are easily activated with the Smart Set button on the remote controller.
  • Powerful Mode
  • The powerful setting on the MSZ-FH indoor units makes it easy to get your zones to the perfect temperature quickly. When activated, a unit temporarily increases refrigerant flow and fan speed to provide quick comfort through rapid heating or cooling.
  • Econo Cool Mode
  • By slowly adjusting the cooling set point and swinging the horizontal vanes, an MSZ-FH mini split indoor unit can improve the efficiency of cooling operations without compromising the comfort provided.
  • Dehumidification
  • When an indoor unit runs in dry mode, the coil's temperature stays just below the dew point of the return air, removing unwanted moisture. This improves comfort and reduces the chance of mold growth and other property damage in the conditioned space.
  • Vane Control
  • Optimal air flow can be achieved with the MSZ-FH units thanks to independent vane control and two vane control options, standard and wide. Auto mode selects the best vane position based on operating mode while swing mode cycles through each vane position.
  • Recommended line set sizes for indoor unit connectivity:
  • MSZ-FH12NA: 1/4" x 3/8" Line Set
  • MSZ-FH15NA: 1/4" x 1/2" Line Set (Qty 2)
  • A branch box with a 3/8" x 5/8" line set connection is also required. Additional branch boxes and line sets may be required based on your configuration.
  • Product Includes
    • (1) Mitsubishi - 36k BTU - M-Series H2i Outdoor Condenser - For 2-4 Zones (MXZ-4C36NAHZ)
    • (2) Mitsubishi FH-Series 15k BTU Wall Mounted Unit - For Multi or Single-Zone (MSZ-FH15NA)
    • (1) Mitsubishi FH-Series 12k BTU Wall Mounted Unit - For Multi or Single-Zone (MSZ-FH12NA)
    Product Note
    This product requires the following accessories for installation:

    • Branch Box - A Mitsubishi PAC-MKA30BC or PAC-MKA50BC branch box is required to connect the refrigerant and power lines from the outdoor condenser to the indoor units.
    • Line Set - This double insulated tubing transfers refrigerant efficiently between your outdoor condenser and indoor units.
    • Drain Tubing - Drain tubing facilitates the reliable and effective removal of condensate from your system. It connects your indoor units to drain locations of your choosing.
    • Disconnect Box & Electrical Whip Kit - The Disconnect Box & Whip Kit provides a safe and simple way to connect your outdoor condenser to your fuse box.
    • Connecting Wire - This durable, insulated wire provides power to your indoor units from your outdoor condenser.
    • Outdoor Condenser Plastic Pad or Wall Bracket - We recommend outdoor condensers should not be placed directly on the ground. An outdoor condenser pad or wall bracket will provide a stable way to mount your condenser free from obstructions and debris.
    Adding these accessories to your order will provide a complete, ready-to-install mini split system. All Mini Split Systems require one Primary Mini Split Installation Kit. You may also require one or more Secondary Installation Kits if you have a Multi-Zone system. You will need a Secondary Installation Kit for each additional indoor unit.

Can these systems can be controlled by the Nest learning thermostat?
Jeff 
from New York 
February 15, 2017
Answer
Mitsubishi mini splits can be controlled with a Nest or any other standard thermostat, but you will need one thermostat for each indoor unit you wish to control. You will also need a thermostat interface, PAC-US444CN-1, and a transformer, 90-T40M3, for each indoor unit.

Do I need a branch box with this system?
Eric 
from Connecticut 
August 23, 2016
Answer
Yes, this system will require a branch box. We recommend the Mitsubishi PAC-MKA30BC for the 3-zone application.

When the room units are hung is it necessary to have holes through to the exterior of the house?
Kevin B. 
from New York 
August 07, 2016
Answer
For each indoor unit, both line sets and connecting wire must run back to the outdoor unit, so a hole to the exterior is necessary. You can make a penetration for each indoor unit, or you can make a single larger penetration centrally (near the outdoor unit) to fit all the required pipes and cables. You can seal the hole(s) afterwards.

What is hyper heating?
Dan P. 
from Texas 
August 05, 2016
Answer
Hyper-Heating (also called H2i) is Mitsubishi's low-ambient temperature (outdoor temperature) heating technology. H2i units are capable of delivering nearly 100% of their rated heating capacity down to 0° F, and are capable of running in temperatures as low as -13° F.
+
Can this unit be used for a business?
Joe 
from New York 
December 30, 2015
Answer
Yes, there is no reason the Mitsubishi M-series units can't be used in an office or store front. However if you are using the unit to cool equipment, such as a server, that requires cooling 24 hours a day 365, I would suggest using a Mitsubishi P-Series unit. These are more robust and will perform better under these conditions than the M-Series units.
+
Does this unit only provide heating? Or does it do both heating and cooling?
Anna 
from Illinois 
December 25, 2015
Answer
While the Mitsubishi Hyper-Heating units are designed to provide exceptional low temperature heating performance, like all heat pumps, they are capable of both heating and cooling.
