LBA Time
When freezer temperature is not changed over 1.0 (2℉) during set LBA time, it regards
as abnormal compressor and it displays error. When error occur, compressor is
controlled according to the set compressor operation cycle and duty ratio.
Compressor Protection
This function is for preventing compressor from life cycle shortening or malfunction
by overload and frequent ON/OFF of compressor. As compressor protection settings,
when compressor output does not ON, the COMP indicator is flashing.
■ Compressor start up delay and restart delay time
If power turns ON instantly from break-down or power OFF, it delays start-up during
the set time of compressor. To prevent frequent compressor ON/OFF, set compressor
■ Compressor Min. operation time
To prevent frequent compressor ON/OFF, set min. operation time.

01) When starting compressor, if PV is out of hysteresis range, compressor output does not turn ON and the COMP
indicator is flashing during compressor start-up delay time.
02) When PV is out of hysteresis, compressor output does not turn ON and the COMP indicator is flashing during
compressor restart delay time.
03) If PV is below the SV, compressor output maintains ON status during compressor Min. operation time. After
compressor min. operation time, it turns OFF.
Defrost Control
When operating a compressor for a long time, an evaporator and a freezer are freezing
and thermal efficiency of compressor is decreased. For increasing thermal efficiency,
defrost operation helps to remove frost or ice around of evaporator.
Set defrost cycle, time, etc. to operate defrost (heater defrost).
The DEF indicator turns ON during defrost output and it flashes during defrost delay
operation.
■ Defrost cycle/time
Set defrost cycle and time to operate defrost at every set cycle and during the set time.
If defrost cycle is set as '0', only manual defrost is available.
■ Defrost end delay and Evaporator-fan start up delay time
Defrost end delay time and Evaporator-fan start-up delay time operate individually
bye one setting.
• Defrost end delay time: During defrost operation, drops may exist at evaporator. Set
the time to drain remained drops after completing defrost.
• Evaporator-fan start up delay time: If evaporator temperature is increased by defrost
operation, warm air may flow into cooling system by Evaporator-fan operation. Set
Evaporator-fan start-up delay time to prevent warm air inflow, and it may increase
cooling efficiency.
Compressor Operation Cycle, Duty Ratio When Error Occur
If normal temperature control is impossible due to error, it controls compressor
output by the set operation cycle and duty ratio to protect control object. Until error is
cleared, operation cycle and duty ratio are applied repeatedly.

When compressor operation cycle when error occur is set as 10 min and compressor
duty ratio when error occur is set as 50%, compressor output has 10 min cycle and turns
ON for 5 min and turns OFF for 5 min.
