Fan cut in during defrost
Here you can set whether fan is to operate during defrost.
0: Stopped (Runs during pump down)
1: Running (stopped during "fan delay")
2: Running during pump down and defrost. After that stopped
Defrost sensor
Here you define the defrost sensor.
0: None, defrost is based on time
1: S5
2: S4
Pumpdown delay
Set the time where the evaporator is emptied of refrigerant prior to the defrost.
Defrost on demand – aggregate refrigeration time
Set here is the refrigeration time allowed without defrosts. If the time is passed, a
defrost will be started.
With setting = 0 the function is cut out.
Defrost on demand – S5 temperature
The controller will follow the effectivity of the evaporator, and via internal calcula-
tions and measurements of the S5 temperature it will be able to start a defrost when
the variation of the S5 temperature becomes larger than required.
Here you set how large a slide of the S5 temperature can be allowed. When the value
is passed, a defrost will start.
The function can only be used in 1:1 systems when the evaporating temperature
will become lower to ensure that the air temperature will be maintained. In central
systems the function must be cut out.
With setting = 20 the function is cut out
If you wish to see the temperature at the defrost sensor, push the controller's lower-
most button.
If you wish to start an extra defrost, push the controller's lowermost button for four
seconds.
You can stop an ongoing defrost in the same way
The LED on the controller's front will indicate whether a defrost is going on.
Fan
Fan stopped at cut-out compressor
Here you can select whether the fan is to be stopped when the compressor is cut out
Delay of fan stop when compressor is cut out
If you have chosen to stop the fan when the compressor is cut out, you can delay the
fan stop when the compressor has stopped.
Here you can set the time delay.
Fan stop temperature
The function stops the fans in an error situation, so that they will not provide power
to the appliance. If the defrost sensor registers a higher temperature than the one set
here, the fans will be stopped. There will be re-start at 2 K below the setting.
The function is not active during a defrost or start-up after a defrost.
With setting +50°C the function is interrupted.
The LED on the controller's front will indicate whether a defrost is going on.

Questions and answers
Is there a possibility with the EKC 202D2 to correct the temperature sensor reading offset,
Yes, the Danfoss EKC 202D can correct the temperature sensor reading offset. This is done using the parameters r09 and r10, which allow for the correction of the signal from sensors S4 and S3, respectively. Both parameters have a correction range of -10.0 K to 10.0 K.
