4. Capacity Code Setting (DSW3)
No setting is required because of factory settings. This switch is utilized for setting the capacity code
that corresponds to the capacity of the indoor unit.
3. Unit No. Setting (RSW1 and DSW6)
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
positions. It is recommended that you assign a
number to each indoor unit beginning with “1”.
A maximum of 64 indoor units per refrigerant
system can be connected to an H-LINK ll
System. Though the available numbers range
from zero to 63, the applicable number for the
64
th
indoor unit in theory replaces the number
"zero".
For the centralized control, this setting is
required.
