NOTICE
Make sure that both the domestic hot water tank and the space heating circuit are
filled before turning on the power of the unit.
If not filled before turning on power, and in case Emergency is active, the backup
heater thermal fuse may blow. To avoid breakdown of the backup heater, fill the unit
before turning on power.
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 36 h
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.
