What is a multi room system?

While a standard heat pump system consists of an indoor and outdoor unit, a multi room system allows you to connect multiple indoor units to a single outdoor unit. The World Health Organisation recommends a minimum indoor temperature of 18-20°C for living areas and 16°C overnight for bedrooms. With a multi room heat pump system you have the freedom to choose the ideal unit for each area to keep you comfortable, without cluttering the exterior of your home. Plus, you get the benefit of the superior efficiency and energy savings of Mitsubishi Electric heat pump technology.

Why choose a multi room system?

We know that every home is as individual as its owner. Mitsubishi Electric multi room heat pump systems allow you to choose the perfect model for each room without the need to install multiple outdoor units.

Multiple Rooms with Individual Control From a Single System

With a multi-room system, you can enjoy your ideal level of comfort in the most important rooms in your home. each room (zone) operates independently. People in difference rooms – the kitchen, master bedroom or living room – can enjoy temperature settings that make each of them most comfortable.

If you’re looking for a complete comfort solution for several different rooms, the MXZ multi-room system is the right choice. The system is flexible enough to conform to your particular cooling and heating needs, with over 40 different indoor unit combinations, up to four indoor units connected to one outdoor unit. And now, with a SEZ horizontal ducted unit, you can enjoy an even greater range of zoning options provided by an MXZ system.

An MXZ multi-room system is an excellent choice for supplementing capacity to your current system or to condition newly finished spaces or new additions. you can also benefit from lower energy costs year-round while staying comfortable, thanks to Mitsubishi’s energy-efficient technologies.

    Multiple rooms with individual control from a single system

    Enjoy ideal levels of comfort in the rooms you use most with our multi–room system. Each room (zone) operates independently. People in different rooms – the kitchen, master bedroom, or living room – can enjoy temperature settings that make each of them most comfortable.

    If you’re looking for a complete comfort solution for several different rooms, the MXZ multi-room system is the right choice. The system is flexible enough to conform to a particular cooling and heating need and offers numerous different indoor unit combinations. In addition up to eight indoor units can be connected to one outdoor unit. Now with a SEZ horizontal ducted unit and a MFZ floorstanding unit homeowners can enjoy an even greater range of zoning options provided by an MXZ system.

    An MXZ multi-room system is an excellent choice for supplementing capacity to a current system, conditioning newly furnished spaces, or new additions and replacing a system within a home. Homeowners can also benefit from lower energy costs year-round while staying comfortable thanks to Mitsubishi Electric’s energy-efficient technologies that are a part of every system that we make.

    To add to the level of energy efficiency, the MXZ-2B20NA and MXZ-3B24NA systems qualify for both ENERGY STAR® and the federal tax credit (See details on page 21 for applicable indoor unit combinations).


    Mitsubishi MXZ-8B48NA: The ultimate zoning solution

    Introducing the Mitsubishi Electric MXZ-8B48NA eight-zone unit. As a member of the expanding MXZ-B Series of multi-zone systems, the MXZ-8B outdoor unit incorporates branch boxes to connect up to eight indoor units.

    The INVERTER-driven compressor at the heart of the MXZ 8B outdoor unit provides variable capacity control for the compressor, allowing the system to adjust to the specific demands of the interior space as needed, not the hard start and stop of a traditional system that is installed in most U.S. homes.

    Unlike the other models of MXZ-B Series outdoor units, the MXZ-8B48NA has only one port on the outdoor unit for two insulated refrigerant lines, which run into the home or business to connect to a branch box or boxes. From there, branch box(es), gas, and liquid refrigerant piping run to each of the indoor units. The LEV in the branch box(es) is used to control the refrigerant flow as the load of each zone changes.

    Through the branch box(es) (the PAC-AKA31BC three-port and/or the PAC-AKA51BC five-port), the system can connect from as few as two indoor units up to eight indoor units, depending on application requirements.

    The flexibility of the system doesn’t stop there. The MXZ-8B48NA has rated capacities of 48,000 Btu/h for cooling and 54,000 Btu/h for heating. System operation, however, can range from a minimum 12,000 Btu/h to a maximum 54,000 Btu/h in cooling and a maximum of 60,000 Btu/h in heating. This type of performance supports a large variety of applications.

    The MXZ-8B48NA allows for further flexibility because it supports a connected indoor unit capacity from 22% to 130% or 12,000 Btu/h to a maximum 70,200 Btu/h, depending on diversity.

    Diamond Comfort Mitsubishi MXZ-8B48NA

    Innovative Compressor Technology

    INVERTER-driven compressor systems in the outdoor unit detect subtle changes in temperature and, like a car’s cruise control, automatically adjust compressor speed – unlike conventional units, which start and stop repetitively. Special components within the compressor increase the magnetic flux and reduce its weight, allowing the compressor to generate higher energy efficiencies with better performance than ever before – at low levels of sound during start-up and running

    Efficient. Quiet. Secure.

    That's right. Reliable Mitsubishi MS-A09WA Mr. Slim units deliver all of these. First its small design, smart functionality, and lack of ductwork plus INVERTER (Models MS-A090WA nad MS-A12WA are the only non-inverter type Mitsubishi systems ) technology make it energy-efficient. Second, the unit's fan is designed to deliver air quietly and continuously with only a gentle whoosh for constant circulation and filtration. (That's why Mr. Slim systems were the first choice for thousands of churches, schools, and libraries across the U.S. Shhh!) Third, because each systems installs with only a three-inch opening for connecting the indoor and outdoor units, you don't have to worry about thieves gaining access through an easy-to-remove window unit. With Mr. Slim systems you can sleep in quiet comfort with a sense of security.

    The Solution is Clear

    • Cool only the areas you want and not the areas where you are not
    • Individual zoning at the push of a button, putting you in total comfort control
    • Less then 5% cooling loss occurs in insulated refrigerant lines versus up to 40% through ducts
    • Requiring just a 3 to 4" diameter hole in the outside wall means less mess, better home aesthetics, and improved security, unlike a window unit
    • Mr. Slim models mount high on the wall so they don't disturb your view
    • Mitsubishi units add value to your home and are more efficient than old window units, saving you money

    Mitsubishi MXZ-8B48NA's Quiet Operation

    Do you hear that? No? You barely hear our systems because Mitsubishi indoor units operate with barely a whisper.

    For example:

    • Police siren 118 decibels
    • Circular saw 107 decibels
    • Vacuum cleaner 74 decibels
    • Library reading room 33 decibels
    • Whisper-tone voice 35 decibels
    • Our Indoor Units 19 - 34 decibels (at low speed)

    Did you hear that? We hope you did.

    System Control in the Palm of Your Hand

    Mitsubishi Electric offers a comprehensive remote controller that controls temperature, fan speed and more. Choose from four modes: COOL, HEAT, AUTO and DRY. The controller also has a 12-hour ON/OFF timer for one-button control of your personal comfort.

    Warm Air, No Drafts

    Our hot-start heat pump technology provides warmth from the beginning. The fan increases in speed as the coil is warmed, reducing drafts so when you want warm air, you’ll get it.

    The Mitsubishi MXZ-8B48NA is Easy to Maintain

    With easily accessible filters, little or no ductwork to clean, and uncomplicated wiring connection points between the indoor and outdoor units, Mitsubishi systems rely on minimal maintenance, providing another level of comfort.
