Regular communication on the identical pipe (every 30 seconds) (Twin Master/Follower)<br />

(Repetition)<br />
• In a group operation, if the indoor unit which was fed power after judgment of automatic address cannot<br />
receive regular communication from the master unit and regular communication on identical pipe within<br />
120 seconds after power was turned on, it reboots (system reset).<br />
→ The operation starts from judgment of automatic address (Gr construction check) again.<br />
(If the address of the master unit was determined in the previous time, the power fed to the master unit and<br />
reboot works, the master unit may change though the indoor unit line address is not changed.)<br />
