Setting to assign an address value to the BS unit for the supervisor remote
controller.
In case supervisor remote controllers are used in the system, it is necessary to
assign an address value to the BS unit.
▪
Assign a different address to different BS units.
▪
Use address values that are NOT used in the system elsewhere (e.g. indoor
units).
▪
Do not use address 00. The supervisor remote controller does not display errors
from BS units with address 00.
This setting only has to be configured on the leftmost main PCB (A1P) of the BS
unit.
