    4-1. Setting M-NET address for various devices The same address cannot be used more than once within the same M-NET system of GB-50ADA. (K-control units and K-control remote control addresses are excluded.) M-NET Address setting method address Assign the lowest address to the main indoor unit in the group, and assign sequential Indoor unit 1 ~ 50 addresses to the rest of the indoor units in the same group.
  • Page 11 * Main and Sub system controllers (M-NET) GB-50ADA can be used only as the Main controller, not as a Sub controller. Main system controller (Main SC) Main SC refers to a controller that controls all other system controllers including the units they control. If a given system has only one system controller, that controller becomes a Main controller.
