Auto restart
When power returns after a power supply failure, the auto restart function
reapplies the user interface settings at the time of the power failure. Therefore, it
is recommended to always enable the function.
If the preferential kWh rate power supply is of the type that power supply is
interrupted, always enable the auto restart function. Continuous hydro module
control can be guaranteed independent of the preferential kWh rate power supply
status, by connecting the hydro module to a separate normal kWh rate power
supply.

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.

Power saving function
Defines whether the power supply to the compressor module can be interrupted
(internally by hydro module control) during stand-still conditions (no space
heating/cooling). The final decision to allow power interruption of the compressor
module during standstill depends on the ambient temperature, compressor
conditions and minimum internal timers.
