DIP Switches Settings

(1) Turn OFF the power supply to both indoor and outdoor units before adjusting DIP switch settings.
Otherwise, the setting will be invalidated and not take effect.
(2) Positions of DIP switches are shown below.
(3) Unit No. Setting
Setting is not required.
Indoor unit numbers are set by the auto-address
function. If an indoor unit number setting is
required, set the unit number of all indoor units
respectively and sequentially by following setting
position. It is recommended that you assign a
number to each indoor unit from "1". A maximum
of 64 indoor units per refrigerant cycle can be
connected to an H-LINK ll System. Though the
available numbers range from zero to 63, the
applicable number for the 64
theory supplants the number "zero".
For the centralized control, this setting is
required.
(4) Capacity Code Setting (DSW3)
No setting is required, due to setting before shipment. This switch is utilized for setting the capacity
code which corresponds to the capacity of the indoor unit.
