[1] Setting data read out from EEPROM<br />
The setting data modified on the site, other than factory-set value, stored in the EEPROM shall be read out.<br />
Step 1 Push SET , CL and TEST button on the remote controller simultaneously for more than 4 seconds.<br />
∗ When the group operation control is performed, the unit No. displayed for the first time is the header unit No.<br />
At this time, the CODE No. (DN) shows “10 ”. Also, the fan of the indoor unit selected starts its operation<br />
and the swing operation also starts if it has the louvers.<br />
Step 2 Every time when the UNIT LOUVER button is pushed, the indoor unit No. under the group control is displayed in<br />
order. Specify the indoor unit No. to be replaced.<br />
1. Change the CODE No. (DN) to 10 → 01 by pushing / buttons for the temperature<br />
setting. (this is the setting for the filter sign lighting time.)<br />
At this time, be sure to write down the setting data displayed.<br />
2. Change the CODE No. (DN) by pushing / buttons for the temperature setting.<br />
Similarly, be sure to write down the setting data displayed.<br />
3. Repeat the step 2-2 to set the other settings in the same way and write down the setting data as shown<br />
in the table 1 (example).<br />
∗ The CODE No. (DN) are ranged from “01 ” to “FF ”. The CODE No. (DN) may skip.<br />
Step 3 After writing down all setting data, push TEST button to return to the normal stop status.<br />
(It takes approx. 1 min until the remote controller operation is available again.)<br />
CODE No. required at least<br />

12 System address<br />
13 Indoor unit address<br />
14 Group address<br />
1. The CODE No. for the Indoor unit type and Indoor unit capacity are<br />
required to set the rotation number setting of the fan.<br />
2. If the system/indoor/group addresses are different from those before<br />
replacement, the auto-address setting mode starts and the manual<br />
resetting may be required again.<br />
(when the multiple units group operation including twin system.)<br />
[2] P.C. Board for indoor unit servicing replacement procedures<br />
Step 1<br />
Step 2<br />
Replace the P.C. board to the P.C. board for indoor unit servicing.<br />
At this time, perform the same setting of the jumper wire (J01) setting (cut), switch SW501, (short-circuit)<br />
connector CN34 as the setting of the P.C. board before replacement.<br />
According to the system configuration, turn on the indoor unit following to the either methods shown below.<br />
a) Single operation (Indoor unit is used as standalone.)<br />
Turn on the indoor unit.<br />
1. After completion of the auto-address setting mode (required time: approx. 5 min.), proceed to [3].<br />
(System address = 1, Indoor unit address = 1, Group address = 0 (standalone) are automatically set.)<br />
2. Push SET , CL and TEST buttons simultaneously for more than 4 seconds to interrupt the auto-address<br />
setting mode, and proceed to [3]. (The unit No. “ ” is displayed.)<br />
b) Group operation (including twin system)<br />
Turn on the indoor unit(s) with its P.C. board replaced to the P.C. board for indoor unit servicing, according<br />
to either methods 1 or 2 shown below.<br />
1. Turn on only the indoor unit with its P.C. board replaced. (Be sure to confirm the remote controller is<br />
surely connected. If not, the operation [3] cannot be performed.)<br />
Perform either methods 1 or 2 described in item a) above.<br />
2. Turn on the multiple indoor units including the indoor unit with its P.C. board replaced.<br />
• Twin 1 system only<br />
• All group connections<br />
After completion of the auto-address setting mode (required time: approx. 5 min.), proceed to [3].<br />
∗ The header unit of the group may be changed by performing the auto-address setting.<br />
Also, the system address/Indoor unit address of the indoor unit with its P.C. board replaced may be<br />
assigned to the addresses (not used) other than those of the indoor units without its P.C. board replaced.<br />
It is recommended to keep the information in advance, which cooling system the indoor unit belongs to<br />
or whether the indoor unit works as the header unit or the follower unit in the group control operation.<br />
