SET
Transmit ECO demo code
and after 2 seconds return to normal
mode.
Press continously for 15s
SET
Transmit check code
and after 2 seconds return to normal

o
If there is abnormal discharge, nanoe-G indicator blinks immediately.
•
Error detection control
When nanoe-G indicator blinks, it indicates error listed below:
o
Nanoe-G connector at main PCB open
Judgment
method
•
During nanoe-G operation, nanoe-G connector at main PCB is opened.
Troubleshooting
method
•
Connect the connector or stop operation to cancel the blinking.
o
Abnormal discharge error
Judgment
method
•
During nanoe-G operation, the nanoe-G system has abnormal discharge due to short-circuit caused
by water or dust adhesion and so forth, with Lo-feedback voltage (at microcontroller).
•
When abnormal discharge occurred, every 30 minutes the unit supplies power to the nanoe-G
system.
•
When abnormal discharge occurs for 24 times continuously, nanoe-G indicator blinks.
Troubleshooting
method
•
Press nanoe-G button or OFF/ON button to stop the operation and check the nanoe-G connector at
PCB.
•
After that, press nanoe-G button again to confirm the nanoe-G indicator do not blinks.
•
The 24 timer counter will be clear after 10 minutes of normal operation or when operation stops.
Error reset method
•
Press “OFF/ON” button to OFF the operation.
•
Press AUTO OFF/ON button at indoor unit to OFF the operation.
•
OFF Timer activates.
•
Power supply reset.
