Features
- Precision Temperature Control Technology
- The MUZ-FH12NA-1 outdoor condenser includes inverter technology and an electronic linear expansion valve. By adjusting compressor speed and refrigerant flow, output can be matched to the zone for precise temperature control and improved efficiency.
- i-see Sensor 3D
- The MSZ-FH12NA's i-see Sensor 3D monitors its zone for fluctuations in temperature. If it detects an underserved area, the MSZ-FH12NA will temporarily direct airflow to that zone. It also enters energy saving mode if no human heat signatures are detected.
- H2i Technology
- Low or negative ambient temperatures don't bother the MUZ-FH12NA-1. 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.
- Advanced Filtration System
- With three unique filters inside the MSZ-FH12NA, the air in your zone is not only being conditioned, but it is also actively being cleaned. These filters remove odors, nanoparticles, and bacteria from re-entering your home.
- Hot-Start
- Mitsubishi's hot start technology prevents cold drafts by delaying fan operation until the heat exchanger has warmed up.
- Smart Set
- Mitsubishi's Smart Set function allows you to save a cooling and heating profile, each consisting of temperature, fan speed, and airflow direction. These are easily activated with the Smart Set button on the remote controller.
- Powerful Mode
- The powerful setting on the MSZ-FH12NA makes it easy to get your zone to the perfect temperature quickly. When activated, the 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, the MSZ-FH12NA can improve the efficiency of cooling operations without compromising the comfort provided.
- Dehumidification
- When the 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-FH12NA with 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.

- (1) Mitsubishi FH-Series 12k BTU Wall Mounted Unit - For Multi or Single-Zone (MSZ-FH12NA)
- Line Set - This double insulated tubing transfers refrigerant efficiently between your outdoor condenser and indoor unit.
- Drain Tubing - Drain tubing facilitates the reliable and effective removal of condensate from your system. It connects your indoor unit 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 unit from your outdoor condenser.
- Base Pan Heater - The base pan heater prevents ice from building up on the outdoor unit. Excessive ice build will lead to performance issues and could damage your unit.
- 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.
For over 50 years, Mitsubishi has remained at the forefront of the mini split industry thanks to their dedication to providing efficient, user-friendly comfort solutions. Part of Mitsubishi's hyper-heating product line, the MZ-FH12NA is a packaged single zone heat pump mini split system designed to bring high-efficiency zoned comfort to homes in frigid climates. The wall mounted indoor unit, MSZ-FH12NA, boasts a functional design, and operates at volumes as low as 21 dB. Thanks to the included mounting plate, it is easy to install on nearly any wall. The outdoor condenser uses some of the most advanced technology available to modulate temperature without the energy-wasting overshoots and short-cycling associated with simpler systems. With an included wireless remote controller, this system is the perfect combination of convenience and comfort for any application in a sub-freezing environment.
