mode, having auto mode enabled on the connected indoor units does not guarantee that the

system will switch modes when an indoor unit switches modes. Therefore, auto mode does not

work as users expect on a multi-zone system, and is not recommended.

Simultaneous Heating and Cooling

For applications that require simultaneous heating and cooling, Mitsubishi Electric Cooling &

Heating offers two options:

1. For smaller applications, multiple one-to-one single-zone systems.

2. For larger applications, CITY MULTI R2-Series systems. R2-Series systems provide

simultaneous heating and cooling for up to 50 indoor units connected to one outdoor

unit.

Due to continuing improvement, above specification may be subject to change without notice.
