ALWAYS operate the unit with thermistors and/or pressure
sensors/switches. If NOT, burning of the compressor might
be the result.

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

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