5.2.8 Identifying Indoor Units Installed Side by Side
This function is used when operating several receivers or indoor units side by side, to prevent malfunction
from incorrect signals received from the wireless controllers used in other areas.
Only the communication between the paired setting is possible, and four pairs (A, B, C, D) are available.
For example, the receiver set as “A” can only receive signals from the wireless controller set as “A”.

Refer to the “Installation and Maintenance Manual” or the “Operation Manual” for each receiver kit or indoor
