INFORMATION

Protective  functions  –  "Installer-on-site  mode"

.  The  software  is  equipped  with

protective  functions,  such  as  room  antifrost.  The  unit  automatically  runs  these
functions when necessary.

During  installation  or  service  this  behaviour  is  undesired.  Therefore,  the  protective
functions can be disabled:

▪

At  first  power-on:

  The  protective  functions  are  disabled  by  default.  After  12

hours they will be automatically enabled.

▪

Afterwards:

 An installer can manually disable the protective functions by setting

[9.G]:
