A system with one or more outdoor units installed, will need to follow this
method: Outdoor units should be placed from large capacity to small
capacity. The largest should be installed nearest to the first branch joint. You
need to set the largest capacity as the master unit.

2) Place the unit from the large capacity to the small (See the detail
placement illustration)
3) Set 16HP as the main unit, while the 12HP and the 10HP as the slave
