15.4 DIP SWITCH SETTING
1
Turn OFF all the power supply to the indoor and the outdoor
units before dip switch setting. If not, the setting is invalid.

DSW5 (Refrigerant cycle number setting)
RSW2 (Refrigerant cycle number setting)

RSW1 (Indoor unit number setting)
DSW6 (Indoor unit number setting)
DSW9 (Optional function setting)

The indoor unit number of all indoor units are not required.
The indoor unit number are set by the auto-address function.
If the indoor unit number setting is required, set the unit
number of all indoor units respectively and serially by
following setting position. It is recommended to assign a
number to each indoor unit from “1.” Though max 64 indoor
units per refrigerant cycle can be connected to H-LINK ll
System, available numbers range from 0 to 63. Therefore,
the applicable number for the 64th indoor unit shall be “0.”
For the centralized control, this setting is required.

• For units supporting H-LINK II: the unit numbers can be set for
maximum 64 indoor units (No.0-63).
• For units supporting H-LINK: the units numbers can be set for
maximum 16 indoor units (No.0-15).
Example: set at number 16 unit

Capacity code setting (DSW3). No setting is required, due to
setting before shipment. This switch is used for setting the

Fuse recover (DSW7). In the case of applying high voltage
to the terminal 1 and 2 of TB2, the fuse (0.5A) on the PCB
is cut, firstly reconnect the wirings correctly to TB2, and then
turn on Number 1 pin.

• When the unit number and the refrigerant cycle are set, record
the unit number and refrigerant cycle to facilitate maintenance
and servicing activities thereafter.
