Within ( ): Address

a.Be sure to use shielded cable for wiring between the outdoor units (OC and OS) and indoor units (IC), between OC and OC and between IC and IC.

b. Terminals M1 and M2 and the ground terminal of the transmission line terminal block (TB3) of each variable capacity unit (OC), terminals M1, M2 and S of the transmission line terminal block (TB3) of the constant capacity unit (OS) and terminals M1, M2 and S of the transmission line terminal block (TB5) of each indoor unit (IC) should be cross wired.

 

c. Connect the M1 and M2 terminals of the transmission line terminal block (TB5) of the indoor unit IC (Main) with the smallest address within

 

 

the same group to the remote control (RC) terminal block (TB6).

method

d. Connect terminals M1, M2 and S of the centralized control terminal block (TB7) of the variable capacity unit (OC) and the terminals M1, M2

 

and S of the centralized control terminal block (TB7) of the variable capacity unit (OC) of the other cooling systems.

 

 

 

e. The power supply connector on the main board can be changed from CN41 to CN40 for only one variable capacity unit (OC).

setting

f. Connect the S terminal of the centralized control terminal block (TB7) of the variable capacity unit (OC) which had its power supply connec-

 

tor connected to CN40 in e to the ground terminal

in the electrical equipment panel.

 

 

 

g. Group settings between multiple cooling systems should be performed after the power is turned on using the remote control (RC) units. For

address

 

the setting method, refer to the installation manual for the remote control unit.

Note:

1.If the address of the variable capacity unit or the constant capacity unit is set at 100, set the address setting switch at either 01 or 50.

2.It is not necessary to set the 100’s position on the remote control unit.

3.If the addresses overlap with the variable capacity unit of other cooling systems, select a different unused address.
