Master unit: The master unit receives the indoor unit data (thermo status) of the sub
(Without identical line address & indoor/outdoor serial) and then finally controls the outdoor
compressor matching with its own thermo status.
The master unit sends this command information to the sub unit.
Sub unit: The sub unit receives the indoor unit data from the master (With identical line address &
indoor/outdoor serial) and then performs the thermo operation synchronized with the master
unit.
The sub unit sends own thermo ON/OFF demand to the master unit.
(Example)
No. 1-1 master unit sends/receives signal to/from No. 1-2 and No. 1-3 sub units.
(It is not influenced by the line 2 or 3 address indoor unit.)
