12-2. 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

= Single (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 air direction adjustment of louver)

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)

Master unit (Representative unit) (Master Twin)

:This unit communicates with the indoor unit (follower) which serial-communicates with the outdoor units and sends/receives signal (Command from compressor) to/from the outdoor units as the representative of the cycle control in the indoor units of the identical line address within the minimum unit which configures one of the refrigerating cycles of Twin.

Follower unit (Subordinate unit) (Follower Twin)

:Indoor units excluding the master unit in Twin

This unit communicates with (Master) indoor unit in the identical line address and performs control synchronized with (Master) indoor unit.

This unit does not perform the signal send/receive operation with the outdoor units. : No judgment for serial signal error.
