Group Number setting for Indoor Units
- Confirm the power of whole system(Indoor Unit, Outdoor Unit) is
OFF, otherwise turn off.
- The communication cables connected to CEN.A and CEN.B terminal
should be connected to central control of Outdoor Unit with care for
their polarity (A-A, B-B ).
- Turn the whole system on.
- Set the group and Indoor Unit number with a wired remote control.
- To control several sets of Indoor Units into a group, set the group ID
from 0 to F for this purpose.

Master IDU in zoning.
!
Setting method of Master indoor unit in zoning
1 Turn dip switch 5,6,10 on at system off.
2 Set the left Ratary switch for HR unit.(Rotary switch No. "0" ‘ HR
unit No. "1")
3 Set the right Ratary switch for IDU unit.(Rotary switch No. "0" ‘ HR
unit branch No. "1")
4 Display the Master IDU No. of the HR unit on 7segment.(Default
display is "00" on 7segment)
5 Press the black button.(The IDU No. increase every 1 second in the
zoning )
6 Set the Master IDU(Press the red button during 1.5seconds stop
twinkling)
Method of checking the pipe detection result
at outdoor unit
1 Wait for 5 minutes, after Pipe detection is completed.
2 Turn on the No.10,14,16 DIP S/W of SUB PCB at master unit
3 Check the data on 7- segment, switching rotary 01,02.
Identification of Manual Valve ID (Address)
Example of checking valve address
(In case that an indoor unit of central control address "11" is connected
to a valve #1 of an HR unit)
