The indoor unit uses refrigerant to cool or heat air and quietly pushes the chilled air where you need it in your living space. Refrigerant and electrical lines connect the outdoor unit to the indoor unit through a 3" opening in the exterior wall.
The outdoor unit’s state-of-the-art heat pump cools or warms refrigerant and sends it back inside to the air handler, which continuously monitors the room for changes in temperature and sends conditioned air to the areas of the room that need it.
If you're using ductless as a whole home solution, up to 8 indoor units can be installed using the same outdoor unit. The multi-zone cooling and heating requires one compressor which is connected to two or more indoor units. The number of indoor units depends on the number of zones or rooms that you have targeted for cooling and heating. Typically, one compressor unit can be connected to up to eight air handlers or indoor units.
Thanks to Mitsubishi Electric’s Advanced INVERTER-Driven Compressor Technology, you can achieve consistent temperatures throughout your space while saving energy during both the summer and winter months. The compressor speed is controlled to maximize efficiency, changing speeds according to the cooling or heating needs of your room(s).
Like a car’s cruise control, the system varies the compressor speed, which reduces power consumption for energy savings. This is different from conventional systems, which start and stop repetitively, wasting energy.
Multiple Ways to Control
When it comes to monitoring or adjusting the temperature in your home, you have plenty of options.Each indoor unit comes with it’s own remote control. Also, Mitsubishi Electric offers a variety of thermostat options; even the option to control your heating and air conditioning from virtually anywhere with a smartphone.
One outdoor compressor can power up to eight indoor units, each separately controlled by a wireless remote, offering you flexible options for configuring your comfort solutions. You can even choose to add units to your compressor in the future after you’ve installed just two indoor units (depending on the maximum number of connectable units), allowing for more streamlined expansion or renovation of your home as time and budget allow.
