(  ) Address

<Wiring Method and Address Settings>

a. Always use shielded wire when making connections between the heat source unit (OC) and the indoor unit (IC), as well for all OC-OC, and IC-IC wiring intervals.

b. Use feed wiring to connect terminals M1 and M2 and the earth terminal on the transmission cable terminal block (TB3) of each heat source unit (OC) to terminals M1,

M2 and terminal S on the transmission cable block of the indoor unit (IC).

c.

Connect terminals 1 (M1) and 2 (M2) on the transmission cable terminal block of the indoor unit (IC) that has the most recent address within the same group to the
terminal block on the remote controller (RC).

d. Connect together terminals M1, M2 and terminal S on the terminal block for central control (TB7) for the heat source unit (OC).

e. On one heat source unit only, change the jumper connector on the control panel from CN41 to CN40.

f.

Connect the terminal S on the terminal block for central control (TB7) for the heat source unit (OC) for the unit into which the jumper connector was inserted into CN40
in Step above to the ground terminal 

 in the electrical component box.

g. Set the address setting switch as follows.
*

To set the outdoor unit address to 100, the outdoor address setting switch must be set to 50.

Unit

Range

Setting Method

IC (Main)

01 to 50

Use the most recent address within the same group of indoor units.

IC (Sub)

01 to 50

Use an address, other than that of the IC (Main) from among the units within the same group of indoor units. This must be

in sequence with the IC (Main)

Heat source Unit

51 to 100

Use the most recent address of all the indoor units plus 50

M-NET R/C (Main)

101 to 150

Set at an IC (Main) address within the same group plus 100

M-NET R/C (Sub)

151 to 200

Set at an IC (Main) address within the same group plus 150

MA R/C
