P.C. Board Exchange Procedures

Indoor unit

7-1. Replacement of indoor P.C. boards

Points to note when replacing indoor P.C. board assembly

The electrically erasable programmable read-only memory (hereinafter EEPROM, IC10) mounted on an indoor
P.C. board holds important setting data, including the type and capacity codes intrinsic to the model (set at the
factory), as well as the line / indoor / group addresses, high ceiling adjustment setting and the like (during
installation, either automatically or manually). Proceed with the replacement of an indoor P.C. board assembly in
accordance with the procedure described below.
After completion of the work, check the settings again, including the indoor unit No. and group header / follower
designation, and confirm the integrity of the refrigerating cycle by conducting a test operation, etc.

<Replacement procedure>

Method 1

If it is possible to turn on the indoor unit and read the setting data from the P.C. board to be replaced via a wired
remote controller -

Reading EEPROM data:

Procedure 1

Replacing P.C. board and turning on power:

Procedure 2

Writing EEPROM data in new EEPROM:

Procedure 3

Resetting power supply (applicable to all indoor units connected to remote controller in case of group operation)
