Troubleshooting Guide
130 Indoor Unit
[In case only one Indoor Unit or only few Indoor Units display 'ch05' error ]
1) Re-operate the Auto-Addressing function and then confirm the Auto-Addressing in all Indoor Units.
Auto-Addressing can be confirmed at the Wired Remote Controller.
In case of the Indoor Units not having the Wired Remote Controller, check the blinking counts of the Indoor
Unit panel (Auto-Addressing must be operated after minimum 1 minute of power On ) › Check the Indoor Unit
not having Auto-Addressing and replace the concerned unit PCB if required.
2) Make sure to separate the communication wire and the power line (AC220/380V ) by a distance of minimum
30 cm.
CAUTION
• In case you replace the communication wire by power 220V line, then the connected PCB gets damaged
or burnt.
To carry out Auto-Addressing
function, press red button until
you see '88 'displayed on 88
