Defrost Start Timer Type
Select the type of timer to start a defrost cycle:
rEL: Real Time = The defrost start time will continuously count regardless of whether the compressor is On or Off
and the defrost will start when the timer value exceeds the value of dF3 (if enabled).
aCC: Accumulated Time = The defrost start timer will count only when the compressor is On and stops counting
(not resetting) when the compressor is Off. In other words, the timer resumes counting every time the compressor
is On, resulting in counting the accumulated durations during which the compressor has been On. The defrost
will start when the timer value exceeds the value of dF3 (if enabled).
Cnt: Continuous Timer = The defrost start timer will count only when the compressor is On and resets to zero
whenever the compressor is Off. The defrost will start when the timer value exceeds the value of dF3 (if enabled).
Threshold For Enabling Defrost Function
The regulation temperature that the defrost function is enabled. Regardless of any other parameters, if the
regulation temperature is above this temperature, the JEA will never enter defrost mode, unless it’s a forced
defrost (see Cd5).
Defrost Start Interval
The duration between the nish of a defrost cycle and the start of the next one, if not started due to temperature.
Defrost End Interval
The duration of a defrost cycle if not ended due to temperature.
Defrost Start Temperature
The temperature at which a defrost cycle will be initiated. This will only be respected if the evaporator probe is
not faulty.
Defrost End Temperature
The temperature at which the defrost cycle will terminate. This will only be respected if the evaporator probe is
not faulty.
Minimum Defrost Duration
The minimum allowable time for a defrost cycle. The Defrost cycle will not end until this time has elapsed
regardless of if Defrost Start Interval (df4) or Defrost Start Temperature (df6) have been met.
