Parameter list

Attention!
The following parameters are important for the operation of the refrigeration unit. They may only be changed by
specialists. It is therefore recommended that the password for the access to the parameters be kept secret.
If the parameters are changed, the new ones should be entered in the column „Changed Values".
Parameter for mode of operating (enabling by codeword P01 = 22)
The following parameters are as parameter for mode of operating for cooler resp. freezer prepared.
They can be adjust. If neccessary they can restore through P 50 and P 51 to the factory setting (see 7.5.2.3).
Parameter
P28 Signal Display from DCF Antenna
P29 Door contact switch (0=without/1=with)
Defrosting
x0=according to set cycle times
x1 = according to set cycle times, but dependent on running time
of compressor
P30
x2=dependent on set switch-on times (only with DCF Antenna)
x3=defrosting as required
0y="Defrost Start", door contact switched off
1y="Defrost Start", door contact switched on
P31 Max allowable room temperature
P32 Min allowable room temperature
P33 Room temperature differential
P34 Minimum stop time, compressor
P35 Initiation delay, evaporation fan

of icing
P38 Temperature difference to allow switch-on of defrosting
P39 Defrost temperature limit
P40 Drainage time, evaporator
P41 Start temperature, evaporator fan
P42 Delay time, temperature alarm
P43 Upper temperature alarm (Setting + P43)
P44 Lower temperature alarm (Setting – P44)
P45 Delay time, door contact alarm
P46 Temperature setting , condenser for rotation speed regulator
P47 Rotation speed, condenser fan in %
P48 Min rotation speed, condenser fan in %
P49 Conductivity, rotation speed regulator, condenser fan
P50 Unit type, 1=normal refrigeration, 2=Deepfreezer
P51 Revert to plant settings (P=78)
