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.

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. 2-60 ACP
