3) Press “ON” button to confirm the selection IDU or ODU, then icon “RM” or “OAT” will light from blinking.
 If “OAT” is confirmed,
press “+” or “-” button to select object ODU.”0x01” means master ODU,”0x02” means slave 1 ODU,”0x03”
means slave 2 ODU,”0x04” means slave 3 ODU. Then “0x01”- “0x02”-“0x03”-“0x04” will be blinking
instead of SPT.
then press “ON” to confirmed the selected ODU, LWCS should read master/slave ODU temperature (OAT)
from its RAM and display it in the place of SPT.
 If “RM” is confirmed,
press “+” or “-” button to select object IDU by its physical address,
then press “ON” to confirmed the selected IDU, LWCS receives RAT message from local bus and save it,
and display it in the place of SPT.
4) Press “OFF” button during the step 1-4 will exit to last operation level.
5) Press “FAN” button again will exit temperature check function.
(4) Diagnose the malfunction of every indoor unit /outdoor unit
 Up to 80 IDU current/history faults can be browsed.
 Up to 5 history faults and 10 current faults for master ODU can be browsed.
1) Press “LOUVER” button one time, icon is blinking, it means current fault diagnose.
Press “LOUVER” button two times, icon is light, it means history fault diagnose.
Press “LOUVER” button three times, exit diagnose function.
2) Press “+” or “-” button to scroll Group-ODU, “RM” means IDU, “OAT” means master ODU,
3) Press “ON” button to confirm the select object.
 If “OAT” is confirmed,”0x01” will be blinking in the place of SPT. then press “+” or “-” button to scroll
master ODU or slave 1 ODU or slave 2 ODU or slave 3 ODU. Then “0x01”- “0x02”-“0x03”-“0x04” will be
blinking instead of SPT. Press “ON” button to confirm the object ODU. LWCS shows the latest
current/history fault code of selected ODU in the place of SPT, then press “+” or “-” button to browse other
fault code.
 If “RM” is confirmed, the min physical address will displayed in the place of SPT, then press “+” or “-”
button to scroll physical address of the group. Press “ON” button to confirm the object indoor unit. LWCS
send requirement message to the selected IDU, selected IDU will send all of current/history fault code (up to 5)
to LWCS. LWCS waits for no more than 1s even though the fault code number is less than 5, LWCS save them
in its RAM and shows the latest one in the place of SPT. Press “+” or “-” button to browse all the fault
codes.
4) Press “OFF” button during the step 1-4 will exit to last operation level.
(5) Diagnose the malfunction of LWCS itself
1) Long press “LOUVER” button more than 5s to enter this function, icon is light, LED is blinking.
2) Press “+” or “-” button to browse fault code of LWCS which shows in the place of SPT.
3) Long press “LOUVER” button more than 5s again, icon is OFF, LED is light if no any fault occur of the
system.
(6) If enter Easy Check function from INIT state
Only diagnose the malfunction of LWCS itself is valid.
