NOTICE
Water pipe freeze prevention. Even if you turn OFF space heating/cooling operation
([C.2]: Operation > Space heating/cooling), water pipe freeze prevention –if
enabled– will remain active.
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.
