Unlock Keys
To prevent un-authorized persons from editing parameter values, there
is a locking function which allows only the most important parameters
to be changed at any time. All other parameters must be unlocked
beforehand. This means that at parameter P48 a certain value is to be
set (see parameter listing) :
Press key "P" ............. parameter number appears
Use "
ñ
/
ò
" ................. select code parameter (P48)
Press "P" again ......... parameter value appears
Use "
ñ
" ..................... set value to 88 or 70 (see parameters)
Press "P" again ......... value is stored, back to parameter no.
If no key is hit for about four minutes, the access code is cancelled and
the editing function is locked automatically.
The display switches back to parameter P01 (P03 if pressostat is
selected).
After entering access code '70' to change parameters of the
basic configuration, the unit initiates a fast backrun.
The control functions start again, if the access code will be
changed manually (e. g. to '88', to change other parameters)
or automatically after 4 minutes.

Press and hold "P" longer than > 3 seconds
One of this 3 values occur on the display:
106 = Mode for compressor compounds
206 = Mode for condenser fans
300 = Mode for brine chillers
