* Fan control.
The ALFA(NET) 55 RTDF has several parameters for fan control. Normally the fan is always active,
accept for one of the following parameters is set to 1, the fan can be stopped:
Parameter 20 = 1 Fan switch differential active:
The fan is only active when the defrost temperature is “parameter 21" lower than the measured
product temperature.
Fan on : Tdefr.<(Tcontrol-Tfandiff.(P21)) As there are no further
conditions to switch the fan off.
Parameter 25,26 Fan on-delay after defrost:
The fan is switched off during defrost and to prevent blowing in hot air in the cabin after defrost and
the dripping-off time (parameter 27), there are two conditions which can be set;
a: The fan is blocked until the defrost sensor measures a temperature lower than the temperature
setting of parameter 25.
b: The fan is blocked until the defrost-delay-time of parameter 26 has stopped. Unless the defrost
sensor has reached the temperature setting of parameter 25.
Parameter 22 = 1 Compressor off than Fan off:
The fan deactivates as the compressor deactivates, with a delay of "parameter 23" minutes.
Provided that there are no other conditions to deactivates the fan.
