MULTIPLE SYSTEMS CONNECTED TO ONE PORT OF DEVICE (DAISY CHAIN

VRF Heat Recovery And VRF Heat Pump Systems

1. Provide every outdoor unit with a network address (ENC 4) starting from 0 up to 7. Maximum number of outdoor units per device is 96. See illustration on Page 15. NOTE – for Double and Triple Module Units – Sub units must NOT have the same network address (ENC 4) as the main unit it serves. ENC 4 must be unique for each refrigerant system on one XY port. Main/sub relationships are defined using ENC 1. See illustration on next page.
2. All Indoor units connected to a VPB outdoor unit are automatically addressed by default (256 total units per device). Use the outdoor unit LCD service console to automatically assign addresses to the indoor units.
3. XY shall connect from the main outdoor unit addressed as 0 (ENC 4), to all other main outdoor units connected to the LVM hardware. XY terminals must be connected to each main outdoor unit via daisy chain connection.
   NOTE – For Double and Triple Module Units – H1H2 terminals needs to be connected from the main outdoor unit to each sub unit should sub units need to be seen from the LVM.
