Note: A system with more than 16 branching requires 2 to 3 BC controllers (main/sub) and 3 pipes between BC controllers.
Note 1: Refer to the graph below for restrictions on refrigerant piping when the total piping length exceeds 300 m.
Note 2: Refer to the graph below for restrictions on refrigerant piping length when the piping length between the BC
controller and the farthest indoor unit exceeds 40 m. (except P250-type indoor units)
Note 3: Use the figures in the parentheses if the capacity of the connected indoor units is P200 type or above.
Note 4: When indoor units of type P200 or above are connected, neither branch joints nor branch headers can be used.
Note 5: When 2 sub BC controllers are connected, include them in the figures in the table above.
Note 6: When 2 sub BC controllers are connected, connect them in parallel.
