Requirement at exchange of P.C. board assembly for indoor service

Before exchange, in the fixed memory (hereinafter EEPROM, IC10) installed on the indoor P.C. board, the type exclusive to the model and the capacity code are stored at shipment from the factory. The important setup data such as line/indoor/group address which are set up (Auto/Manual) or high ceiling exchange setup at installation time, respectively.

Proceed with exchange of P.C. board assembly for indoor service in the following procedure.

After exchange work, check again the setup for indoor unit No. or group header/follower units to confirm whether the setup contents are correct or not, and then check also the refrigerant circuit system by a test operation, etc.

<Exchange procedure>

Method 1

Before exchange, it is possible to turn on power of the indoor unit and read out the setup contents from the wired remote controller.

Readout of EEPROM data: Procedure 1

ò

Exchange of P.C. board for service & power ON: Procedure 2

ò

Writing-in of the readout EEPROM data: Procedure 3

ò

Power supply reset (All the indoor units connected to the remote controller in case of group operation control)
