The header unit sends this command information to the follower unit.

indoor/outdoor serial) and then performs the thermo operation synchronized with the header
unit.  The follower unit sends own thermo ON/OFF demand to the header unit.

No. 1-1 header unit sends/receives signal to/from No. 1-2 and No. 1-3 follower units.
(It is not influenced by the line 2 or 3 address indoor unit.)
