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 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
NOTICE
Power saving function. The power saving function is only applicable for V3 models. If
you want to use the power saving function, on the outdoor unit PCB make sure to
connect X804A to X806A. For more information, see
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.
Alarm output: Indicates the logic of the alarm
output on the digital I/O PCB during
malfunctioning.
▪ 0 Abnormal: The alarm output will be
powered when an alarm occurs. By setting this
value, a distinction is made between the
detection of an alarm, and the detection of a
power failure.
▪ 1 Normal: The alarm output will NOT be
powered when an alarm occurs.
