2. Installing ACP
Note: Physical and Logical group
At the ACP, the connected air conditioners can be grouped by using the concept "Physical group"
and "Logical group."
The physical group is the outdoor unit physically connecting the indoor unit. The example of the
physical group is setting the address to the indoor unit at the installation step. However, the logical
group is used for the convenient control regardless to the physical connection.

For describing the difference between the physical group and the logical group by the example of
the school, as shown at the above figure, the logical group can be said the set of the air
conditioners connected to the same outdoor unit. However, the logical group can be configured
even when the air conditioners at the 1st grade classrooms are connected to the different outdoor
units regardless to the physical connection.
