nanoe-G check mode
o To enable nanoe-G check mode, during nanoe-G operation ON:
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.
o 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.
o 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.
o nanoe-G breakdown error
Judgment method
Hi-feedback voltage (at microcontroller) supplied to the nanoe-G system when nanoe-G operation is
OFF; nanoe-G breakdown error show immediately.
It is due to indoor PCB or nanoe-G high voltage power supply damage.
Operations except nanoe-G continue. Both Timer indicator and nanoe-G indicator blink.
