If the preferential kWh rate power supply is of the type that power supply is
interrupted, always enable the auto restart function. Continuous indoor unit
control can be guaranteed independent of the preferential kWh rate power supply
status, by connecting the indoor unit to a separate normal kWh rate power supply.

Power saving function
Defines whether the outdoor unit power supply can be interrupted (internally by
indoor unit control) during stand-still conditions (no space heating/cooling nor
domestic hot water demand). The final decision to allow power interruption of the
outdoor unit during standstill depends on the ambient temperature, compressor
conditions and minimum internal timers.
To enable the power saving function setting, [E‑08] needs to be enabled on the
user interface.

Protective functions
The unit is equipped with the following protective functions:
▪ Room antifrost [2-06]
▪ Tank disinfection [2-01]
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.
