DIP SWITCH SETTING 5
ENGLISH
4. DIP SWITCH SETTING
1) Dip Switch setting should be performed
with the power of room air-conditioner
OFF. The setting contents are invalid if it
is performed with the power ON.
2) Installation position of Dip Switch is as
below.
CAUTION:
Do not turn ON various pins of DSW1
and DSW2.
3) Refrigerant cycle No. is set by RSW1 and
DSW1.
Refrigerant Cycle No. Setting
4) Unit No. is set by RSW2 and DSW2.
Unit No. Setting
5) Sub Setting
In case of setting various RAC adapters in
the same refrigerant cycle, set the RAC
adapter with smallest Unit No. as a main.
In case of only one RAC adapter in a
refrigerant system, this adapter should be
a main. Set by changing DSW3.
− Main Setting
− Setting before
shipping (Sub setting)
CAUTION:
Do not set various main adapters in the
same refrigerant cycle.
6) In case of wrongly applying high voltage to
H-LINK wiring, fuse installed in a
transmission circuit on PCB is cut. In this
case, after wiring correctly, turn ON No.2
pin of DSW4 on PCB and then
transmission circuit is recovered. (If you
make this error again, the transmission
circuit is not recovered.)
