Most system problems can be diagnosed by reading the status code as flashed by the amber status light on the control board.<br />
The codes are flashed by a series of short and long flashes of the status light. The short flashes indicate the first digit in the status code, followed by long flashes indicating the second digit of the error code.<br />
<br />
The short flash is 0.25 seconds ON and the long flash is 1.0 second ON. Time between flashes is 0.25 seconds. Time between short flash and first long flash is 1.0 second. Time between code<br />
repeating is 2.5 seconds with LED OFF.<br />

3 short flashes followed by 2 long flashes indicates a 32 code.<br />

Sequence: Compressor contactor is de---energized and outdoor fan is energized for up to 15 minutes. If demand still exists, control will energize compressor contactor after 15 minute delay. If fault is cleared, unit will resume operation. If fault still exists, fan shuts off, and error code continues to flash. Control will attempt re--- start every 15 minutes. Cycling low voltage defeats the 15 minute delay<br />

Automatic Restart from Alarm Mode<br />
This Chiller is equipped with an automatic restart feature to avoid false alarms. If any alarm condition is detected the chiller will turn off, wait 30 seconds and then turn on.<br />
This is to avoid nuisance trips due to temporary flow obstructions, temperature swings or electrical line noise.<br />
Three restart attempts will be made. If the alarm condition continues to exist then an alarm will sound and the chiller will remain off until the problem is corrected.<br />

The fault content = EEPROM reading error (outdoor unit)<br />
The reason of fault and its solutions = 1. Check whether there are false weld and bad contact etc between the EEPROM chip block and the electronic control board ;<br />
2. Check whether the EEPROM chip pin is broken foot and the direction of installation is in line with the EEPROM block;<br />
3. When the procedure of EEPROM chip and itself have fault it will appear the code PE. At this time there is the need toreplace the EEPROM chip.<br />

Remove the top plate of outdoor unit and the cover of Electrical Component Box.
The Power Lamp and Error Monitor Lamps are located on the P.C.Board of Electrical Component Box. (Fig.1)
Display of the Error Monitor Lamps
If a protective device has activated or there is a sensor failure in the outdoor unit, the 4 error monitor lamps on the
outdoor control circuit board will indicate the nature of the trouble.
