Mitsubishi Electric's multi-zone systems consist of an outdoor unit and up to eight indoor units, which can be wall-mounted, ceiling-mounted, or floor-mounted, depending on the needs of the building. Each indoor unit is connected to the outdoor unit through refrigerant lines and requires its own thermostat to control the temperature in that specific zone. 

Mitsubishi Electric's multi-zone systems offer a variety of features, including:

1. Hyper-Heating technology, which allows for heating in colder temperatures

2. Inverter-driven compressors, which provide energy efficiency and quiet operation

3. Multiple filtration options, including advanced filters that can remove allergens and pollutants from the air

4. Wireless remote control and smartphone app control options for convenience and ease of use

Overall, Mitsubishi Electric's multi-zone systems offer flexibility and customization for heating and cooling in buildings with varying needs. They are designed to provide efficient and reliable performance for years to come.
