Power failure

During nanoe-G individual operation, if power failure occurs, after power resumes, nanoe-G individual

operation resumes immediately.
During combination operation, if power failure occurs, after power resumes, combination operation resume
o
immediately.
nanoe-G operation status is not memorized after OFF the unit. After OFF the unit, when the operation is ON
o
again, air conditioner operates without nanoe-G operation.

nanoe-G check mode

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:
nanoe-G connector at main PCB open
o
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
Abnormal discharge error
o
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.
