„Indoor unit power-ON sequence

Power ON

•The unit without power feed waits entirely → Waiting status is released by system start

•Reboot when power is fed on the way

<Automatic address judgment>

<By indoor unit

which receives power feed from outdoor unit>

Not normal

NO

Gr construction check

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.

5)Header indoor unit and 1 or more follower units for Gr.

3 minutes elapse

YES

: Approx. 4 to 5 minutes

 

 

Remote controller operation is available.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

(Approx. 50 seconds after power-ON)

 

 

 

 

 

<Usual regular communication>

Regular communication between indoor units (Every 30 seconds) (Header / Follower)

 

(Repetition)

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.)
