8. Types of operational parameters
8.1 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).
