INSTALLATION
This function is used when operating several receivers or indoor units side by side, to prevent a malfunction
because of receiving incorrect signals from the wireless remote 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 designated “A” can only receive signals from the wireless controller designated
as “A”. It cannot receive signals from a wireless controller set as B, C or D.
