• 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.
