Wiring layout of centralized controller should be done according to installaiton manual of centralized controller
Operation control
Solution of group control
One set of remote controller can control a group of 16 indoor unit at the most.
Refer to electrical wiring layout items for wiring layout between indoor unit.
Arrange wires between remote controller and indoor unit according to the following sequence:
(1)Set number setting switch SW01 on PC board of each indoor unit with number 1 as ì1î,
number 2 as ì2î ÖÖ (the machine directly connecting remote controller must be set as number
1î). Number 1 is the host while others are subsidiaries.
(2)Connect terminals A, B, C of the remote controller with that of number 1 indoor unit respectively
(according to same numbers).
(3)Connect terminals B, C of number 1 indoor unit with that of number 2 respectively
(according to same numbers).
(4)Connect terminals B, C of number 2 indoor unit with that of number 3 respectively
(according to same numbers).
(5)By analogy of the above, stop until connecting to terminals B, C of number 16 (at the maximum).
(6)Disassemble short connection wire to CN12 terminal on control base board of number 2-16 indoor
subassemblies to prevent wrong connection that may cause defects.
Wires of remote controller between indoor unit should be power
cord more than 1mm≤ with length less than 500 m (total length from
remote controller to number 16 machine).
Setting of group number of indoor subassemblies
Code switch AW02 on base board of indoor unit has
the function of setting centralized control address (group number).
Group number can be set by changing ìON/OFFî status in ì1-6î code positions.
Code switch SW02 and its dialing codes are shown as following diagram:
ON

6
Relation between combination of
ìON/OFFî status in ì1-6î
code positions and group
number are shown as in right table.
When ì7î position of SW02 is in ìOFFî
status, group number can be set either by
dialing codes on SW02 or with circuit
controller. While ì7î position of SW02
is in ìONî status, group number can only
be set either by dialing codes on SW02.
