Indoor Units Sizes ? 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 ? 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
    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. This is a four zone mini split system designed to give you individual control over the temperature in multiple rooms. An efficient MXZ-5C42NA2 outdoor condenser, built with advanced technology, is combined with quiet wall-mounted MSZ-GL indoor units and four wireless remote controllers for the perfect marriage of convenience and comfort. With multiple operating modes, multiple fan speeds, and multiple airflow directions, this is a system that fits the needs of nearly any home.
  • Precision Temperature Control Technology
  • The MXZ-5C42NA2 outdoor condenser is equipped with inverter technology and an electronic linear expansion valve. These components improve temperature accuracy and system efficiency through precise adjustments of both compressor speed and refrigerant flow.
  • Advanced Filtration System
  • MSZ-GL model indoor units combine a hybrid catechin deodorizing filter with an enzyme-based filter for managing allergens. The anti-allergy filter not only captures the offending particles, it also breaks them down, cleaning the air as it is conditioned.
  • Hot-Start
  • In heating mode, Mitsubishi's hot start technology prevents cold drafts by stalling fan operation while the heat exchanger is warming 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. The Smart Set function can be activated using the included wireless remote controller.
  • Econo Cool Mode
  • By slowly adjusting the cooling set point and swinging the horizontal vanes, the MSZ-GL mini split indoor units 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 your comfort and reduces both mold growth and the chance of property damage in the conditioned space.
  • Vane Control
  • Optimal air flow is easy to achieve with Mitsubishi's MSZ-GL mini split indoor units thanks to the vane control option. This function provides access to five different horizontal vane positions, an auto mode, and a swing mode.
  • Recommended line set sizes for indoor unit connectivity:
  • MSZ-GL06NA-U1: 1/4" x 3/8" Line Set
  • MSZ-GL09NA-U1: 1/4" x 3/8" Line Set (Qty 2)
  • MSZ-GL18NA-U1: 1/4" x 1/2" Line Set
  • Product Includes
    • (1) Mitsubishi - 42k BTU - M-Series Outdoor Condenser - For 2-5 Zones (MXZ-5C42NA2)
    • (1) Mitsubishi GL-Series 18k BTU Wall Mounted Unit - For Multi or Single-Zone (MSZ-GL18NA-U1)
    • (2) Mitsubishi GL-Series 9k BTU Wall Mounted Unit - For Multi or Single-Zone (MSZ-GL09NA-U1)
    • (1) Mitsubishi GL-Series 6k BTU Wall Mounted Unit - For Multi-Zone (MSZ-GL06NA-U1)
    Product Note
    This product requires the following accessories for installation:

    • 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.
    • 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.
    Adding these accessories to your order will provide a complete, ready-to-install mini split system.

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.
