13. ADDRESS SETUP

13-1. Address Setup

<Address setup procedure>

When an outdoor unit and an indoor unit are connected, or when an outdoor unit is connected to each indoor unit respectively in the group operation even if multiple refrigerant lines are provided, the automatic address setup completes with power-ON of the outdoor unit. The operation of the remote controller is not accepted while automatic address works. (Approx. 4 to 5 minutes)

Setup of line address of outdoor unit, indoor unit address, and group address

Completion of cabling work

Do you arbitrarily set the indoor unit address?

YES

(MANUAL)

Connect one remote controller with one indoor unit (1 : 1) tentatively with communication cable.

NO

NO

Is refrigerant line 1 line?

YES

NO

Is group control performed?

YES (To AUTO address mode)

Do you change setting after automatic setting at the first time?

YES

Turn on power of outdoor unit.

Set to all indoor units one by one.

Turn on power of outdoor unit.

Turn on power of outdoor unit.

After completion of address setup, change is to arbitral address/group manually.

address finishes within

4 to 5 minutes.

13-2. Address Setup & Group Control

<Terminology>

Indoor unit No.

: N - n = Outdoor unit line address N (Max. 30) - Indoor unit address n (Max. 64)

Group address : 0 = Individual (Not group control)

1 = Master unit in group control

2 = Sub unit in group control

Master unit (= 1) : The representative of multiple indoor units in group operation sends/receives signals to/from the remote controllers and sub indoor units. (* It has no relation with an indoor unit which communicates serially with the outdoor units.)

The operation mode and setup temperature range are displayed on the remote controller

LCD. (Except sir direction adjustment of flap)

Sub unit (= 2) : Indoor units other than master unit in group operation

Basically, sub units do not send/receive signals to/from the remote controllers.

(Except errors and response to demand of service data)
