TROUBLE SHOOTING (Control Part)
1. Error Display 1) The Meaning of the First Alphabet
E P U A
Error concluded by self-diagnosis
E101~E700Detailed item refers to error code
Pre Error Code
P701~P800 Items that need more than 2 times detection to result in error
The address of Outdoor Unit in which error occurred U200 : Main UnitU201 : Sub1 UnitU202 : Sub2 UnitU203 : Sub3 Unit
The address of Indoor Unit in which error occurred A047 : Error Occurred At Indoor Unit Whose address 47
2) Error Display sequence
Error Type Error Display Sequence Examples
Error Occurred in the Indoor UnitError Number →Address of Indoor unit → Error Number(display repeatly)
E471→A002→E471→A002
Error Occurred in the Outdoor Unit or Other Error
Error Number →Address of Outdoor unit → Error Number(display repeatly)
E471→U200→E471→U200
In case several errors occurred at the same time, seven segment on the outdoor PBA displays only one error whose priority is higher. ( Refer to the errorr code table about priority order )
When the same error occurred in several indoor units, seven segment displays one main address of indoor unit whose address number is lowest.

TROUBLE SHOOTING (Control Part)
2. Initial tracking(communicaton check) – E201 indicated if abnormal
1) When the power is on, the micom of outdoor unit check the indoor units, and transmitters Installed in the same system, which is called as tracking.
2) The left 2 sides of displays shows the address of indoor unit which the outdoor unit is trying to communicate.(0,1,2,~,47)
3) The right 2 sides of displays shows the address of indoor unit which the outdoor unit succeed in communicating.
4) Using outdoor 2 rotary switches to check the numbers of indoor unit connected with outdoor unit
5) If the total numbers of indoor unit don't match with the outdoor switches setting, the 4 segments display E201..
Main unit displays indoor unit main address in sequence from 0 to 47 Sub unit displays only outdoor unit address connected to each other like C9,CA,CB,CC,CD,CE,DF

3. Compressor preheating – Ch displays
( DISCHARGE ≤ COND_Out + 2 ) and ( out air temp) ≤ 30 , for 2 minutes -> CCH ON for 2 and half hours only at first.
( DISCHARGE > COND_Out + 5 ) and ( out air temp) ≥ 32 , for 2 minutes -> CCH OFF
TROUBLE SHOOTING (Control Part)
E201: E201 Communication error in tracking indoor
Judgement Method Check by comparing set values of installed numbers of indoor units on outdoor unitPCB with actual installed numbers.
Possible Cause Communication error between indoor unit and outdoor unit, and switch setting error for installed numbers.
E202: E202 Communication error after completion of tracking
Judgement Method In case that the communication is not achieved for 2 minutes during operation between indoor and outdoor unit.
Possible Cause Communication error between indoor unit and outdoor unit, and switch setting error for installed numbers.
E203: E203 -> 200~203 Communication error between outdoors
Judgement Method In case that the communication is not achieved for 2 minutes during operation between indoor and outdoor unit.
Possible Cause - communication wire short or open-disorder of communication chip, fail of pcb power pcb
TROUBLE SHOOTING (Control Part)
E425: E425 Reverse phase detection of 3 phase power
Judgement Method - check the 3phase detection part power of outdoor unit PCB- check the color of red, white and black of the cabel for 3 phase detection part connectors.- The error is automatically reset when the phase voltage is restored in order.
Possible Cause One of the 2 phase voltages or all of them are not comingIncorrect connection of 3 phase power
E452: E452 Momentary power failure
Judgement Method In case that the communication is not achieved for 2 minutes during operation between indoor and outdoor unit.
Possible Cause Protection control of compressor, not defect
E162: E425 EEPROM error
Judgement Method - micom of indoor unit fail in communicating with the eeprom
Possible Cause Eeprom is in defect

SENSOR OPEN/SHORT ERROR
TROUBLE SHOOTING (Control Part)
Judgement Method 1. Is the connector of temperature sensor departed from PCB?2. Separate the connector from PCB and measure the resistance across both terminals.3. Is the resistance greatly out of that of the each table, 103AT, 204CTB?4. Replace sensor or PCB, measure again, and operate again.
Possible Cause Wire open or current leak of related sensor
