Note: 1. Branch box address
When setting the address, use a number within the range 1–50.
E.g. The set address is (47) and there are 5 indoor units (A, B, C, D, and E).
If A: (47), B: (48), C: (49), D: (50), and E: (51), E is incorrect because it exceeds 50.
E.g. 1. Outdoor + Branch <1> (M, S, P series Indoor A, B, C, D, E) + Branch <2> (M, S, P series Indoor A, B, C) + Branch <3> (M, S, P series Indoor A, B, C)
