INSTALLATION AND OPERATION MANUAL
13.3.4.SYSTEM INSTALLATION DIP SWITCH SETTING
 Dip Switch Setting of Indoor PCB and Outdoor PCB for H-LINK II
It is required to set dip switches of every indoor unit and outdoor unit and match of the transmission circuit impedance.
− Dip Switch Setting Example:
Unit Name of Dip Switch Mark Setting Before Shipment Function
Outdoor
Unit
Refrigerant Cycle
DSW4
RSW1
For setting refrigerant cycle address of Outdoor Unit. Set the DSW4 and
RSW1 not to overlap the setting of other Outdoor units in the same H-
LINK system
Terminating Resistance DSW5
For matching impedance of transmission circuit, set the DSW5 according
to the quantity of outdoor units in the H-LINK system.
Indoor
Unit
Refrigerant Cycle
DSW5
RSW2
For setting refrigerant cycle address of indoor units. Set the DSW5
and RSW2 corresponding to the address of outdoor unit in the same
refrigerant cycle.
Indoor Unit Address
DSW6
RSW1
For setting indoor unit address. Set the DSW6 and RSW1 not to overlap
the setting of other indoor units in the same refrigerant cycle. (If not set,
the automatic address function is performed).
