VRF System Adressing

A system address needs to be assigned to almost all devices on a VRF City Multi system, to allow the correct syncronisation and communication. The devices which must be assigned an address are:

  • Outdoor units
  • Indoor Units
  • BC box and Sub BC boxes (on R2 systems)
  • M-Net type controllers
  • Lossnay Fresh Air systems
  • Additional Ancillary equipment (Pump down panels, Dido Controllers (YG63/YG60),
  • PAC-LV boxes (when connecting M-Series Indoor)

Addressing Rules

Indoor unit (IC) = 1 to 50 Lossnay Unit (LC) = 1 to 50 after last IC of system Main outdoor unit (OC) = First (IC) + 50 Sub outdoor unit (OS) = (OC) + 1 Single or main BC box = (OC) or (OS) + 1 Sub BC box = First (IC) on sub box + 50 Remote controller (RC) = (IC) + 100 Sub remote = (RC) + 50 = (IC) + 150 System controller (SC) = 000 Additional system controller = First (IC) + 200
