A. Example of the use of the shielded cable in a single coolant system (Setting of addresses is necessary)

Example of control line wiring

Wiring method, address setting

Standard

a. Run the wire to terminals M1 and M2 the variable capacity unit (OC)

transmission line terminal block (TB3) and to terminals M1 and M2 on

the constant capacity unit (OS) transmission line terminal block (TB3)

as well as to the terminals M1 and M2 of the transmission line terminal

block (TB5) of each indoor unit (IC). (Two-wire, no polarity)

Also, run the shielded ground wire to the ground terminal of the

variable capacity unit, the S terminal of the constant capacity unit (TB3),
