Power failure
o
During nanoe-G individual operation, if power failure occurs, after power resumes, nanoe-G individual
operation resumes immediately.
o
During combination operation, if power failure occurs, after power resumes, combination operation resume
immediately.
o
nanoe-G operation status is not memorized after OFF the unit. After OFF the unit, when the operation is ON
again, air conditioner operates with nanoe-G operation.

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.
