Parameter setting
The remaining parameters are located in seven folders. [CP][Def][FAn][AL][diS][CnF][FPr]
Press and hold the SET key for minimum 5 seconds during operation. Lighting up of the first
parameter [CP] shows that you are in the system menu. Now, if you press SET again, you
will proceed to the folder and the first parameter [diF] will be displayed. With the keys UP
and DOWN you can navigate through the folder and view the remaining parameters. If you
want to view or alter any parameter, press the SET key, when the parameter is visible in the
display. You can now change the value by the arrow key. Quit the parameter setting mode
with the FNC key. The folders are now displayed again. By pressing the FNC key again, you
will exit the menu and the measured temperature value will be displayed.
Navigate in the system menu by the UP and DOWN keys to view another folder.
Proceed as described above to view, change or quit the parameter setting mode.
Defrost manual activation
To activate the defrosting cycle manually, press and hold the UP key for 5 seconds. If no
conditions for defrosting are provided (e.g. the sensor temperature exceeds the defrosting
end temperature [dSt]), the display will flash thrice and the process will be aborted.
Setting password
1. To set the password, navigate to the parameter [PA1] in the folder [diS].
2. Press the SET key and set your password using navigation keys.
Password query
1. Now, if you try accessing the main menu, the lettering [PAI] will light up.
2. Press the SET key, enter your password and proceed to settings.
Take good care of your password, as there is no possibility of resetting. Neither
viewing nor changing parameters is possible if the password is lost.
