Indoor unit power-ON sequence
<Automatic
address judgment>
Gr construction check
<Initial communication>
Outdoor model distinction (10 seconds) (Indoor unit)
Twin header/follower distinction (Indoor unit)
Gr construction, louver information (Remote controller)
Remote controller operation is available.
<Usual regular
communication>
Regular communication between indoor units (Every 30 seconds) (Header / Follower)
Regular communication of the identical piping system (Every 30 seconds)
(Twin header / follower) (When the above status changes, immediately communicates.)
• In a group operation, if the indoor unit which was fed power after judgment of automatic address cannot
receive regular communication from the header unit and regular communication on identical pipe within
120 seconds after power was turned on, it reboots (system reset).
→ The operation starts from judgment of automatic address (Gr construction check) again.
(If the address of the header unit was determined in the previous time, the power fed to the header unit
and reboot works, the header unit may change though the indoor unit line address is not changed.)

N t o n r o m
Normal
∗ Gr normal
1) There is no duplicated indoor unit address.
2) There is no invalid indoor unit address.
3) Individual unit and header / follower units
are not intermingled.
4) Only a unit for individual.
Header indoor unit and 1 or more
5)
follower units for Gr.
System start
(Approx. 50 seconds after power-ON)
• The unit without power feed waits entirely
→ Waiting status is released by system start
• Reboot when power is fed on the way
l a
Automatic address starts.
<Cautions at test run>
• Power supply/Indoor/Outdoor serial and Gr wiring: OK
• Powers of all indoor units are turned on within 3 minutes.
• Reception time for remote controller operation
(After power supply was turned on)
1) When address is OK : Approx. 50 seconds
2) In AUTO address
