017 HiW Multi-Split Branch Box
MXZ branch box systems require indoor units to be numerically addressed during
installation for the branch box to map the ports to an M-Net address.
One or two branch boxes may be connected to an outdoor unit at a time and come
in 3 and 5 port configurations. The maximum number of ports supported by the
outdoor unit is identified in the product nomenclature (MXZ-4C36NAHZ2,
MXZ-5C42NAHZ2, MXZ-8C48NAHZ2). Additional ports on the branch box will remain
inactive.
M-Net control via 2-core AWG 16 shielded wire is used between the outdoor unit
and branch box. Branch boxes use A-Control communication from the branch box
to indoor units.
M-Net system addressing is performed by setting of rotary switches at the
outdoor and branch box unit(s) and SW1 in branch box. Outdoor units use rotary
switches SWU2 and SWU1; SWU2 represents the 10’s digits and SWU1 the single
digits. Branch boxes use rotary switches SW12 and SW11; SW12 represents 10
digits and SW11 are single digits. Setting dip switches SW1 on the branch box
to ‘ON’ ena bles connectivity o f indoor units to branch box(es).
- The port A of branch box (A) has an address of ‘001’
- Rotate SW12 to ‘0’ and SW11 to ‘1’ for address ‘001’ for branch box (A)
- Three ports are enabled by SW1 , therefore turn dip switches SW1-1, SW1-2, and SW1-3 to ON position
- The first port of branch box (B) is addressed to ‘004’ because addresses ‘001’ to ‘003’ are assigned on branch box (A)
- Rotate SW12 to ‘0’ and SW11 to ‘4’ for address ‘004’ for branch box (B)
- Two ports are required on branch box (B) therefore turn switches SW1-1 and SW1-2 ON
- As branch box (A) is addressed ‘001’ add 50 to determine outdoor address ‘051’
- Outdoor unit: Rotate SWU2 to ‘5’ and SWU1 to ‘1’ for address ‘051’ for first outdoor unit
