The general commissioning checklist is complementary to the instructions in this

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]: Disable protections=Yes. After his work is done, he can enable the
protective functions by setting [9.G]: Disable protections=No.
