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. (If the user interface home pages are off, the unit will not
operate automatically.)
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 36 h
they will be automatically enabled.
▪ Afterwards: An installer can manually disable the protective functions by setting
[4‑0E]=1. After his work is done, he can enable the protective functions by setting
[4‑0E]=0.
Especially for UK:
It is a requirement that the boiler is installed and commissioned to the
manufacturer’s instructions and the data fields on the commissioning checklist
completed in full.
To instigate the boiler guarantee the boiler needs to be registered with the
manufacturer within one month of the installation.
To maintain the boiler guarantee it is essential that the boiler is serviced annually
by a Gas Safe registered engineer who has been trained on the boiler installed. The
service details should be recorded on Service Interval Record and left with the
householder.
