Parameter
Description
EF1
When compressor operates, evaporator-fan also operates. When compressor
operation is finished, evaporator-fan also operation turns OFF.
EF2
When compressor operates, evaporator-fan operates after the set evaporator-
fan start-up delay time. When compressor operation is finished, evaporator-fan
operation turns OFF. (regardless of defroster operation)
EF3
When power turns ON, evaporator-fan operates. When defroster operates,
evaporator-fan stops. (regardless of compressor operation)
EF4
Evaporator-fan operates only when operating compressor or defrost. Evaporator-
fan stops when compressor and defroster stops. (for above zero temperature
control)
EF5
Evaporator-fan operates from power ON to power OFF. (regardless of compressor,
defroster operation)
