13-2. Address Setup & Group Control<br />
<br />
Indoor unit No. : N - n = Outdoor unit line address N (Max. 30) - Indoor unit address n (Max. 64)<br />
Group address : 0 = Single (Not group control)<br />
1 = Master unit in group control<br />
2 = Sub unit in group control<br />
Master unit (= 1) : The representative of multiple indoor units in group operation sends/receives signals to/from<br />
the remote controllers and sub indoor units.<br />
(* It has no relation with an indoor unit which communicates serially with the outdoor units.)<br />
The operation mode and setup temperature range are displayed on the remote controller LCD.<br />
(Except air direction adjustment of louver)<br />
Sub unit (= 2) : Indoor units other than master unit in group operation<br />
Basically, sub units do not send/receive signals to/from the remote controllers.<br />
(Except errors and response to demand of service data)<br />
Header unit (Representative unit) (Master Twin)<br />
: This unit communicates with the indoor unit (follower) which serial-communicates with the<br />
outdoor units and sends/receives signal (Command from compressor) to/from the outdoor<br />
units as the representative of the cycle control in the indoor units of the identical line address<br />
within the minimum unit which configures one of the refrigerating cycles of Twin.<br />
Follower unit (Subordinate unit) (Sub Twin)<br />
: Indoor units excluding the header unit in Twin<br />
This unit communicates with (Header) indoor unit in the identical line address and performs<br />
control synchronized with (Header) indoor unit.<br />
This unit does not perform the signal send/receive operation with the outdoor units. :<br />
No judgment for serial signal error.<br />
