Alarm output
Alarm output
# Code Description
[9.D] [C–09] Alarm output : Indicates the logic of alarm
output on digital I/O PCB during high level indoor
unit error malfunctioning. Low level errors
(caution/warning) will NOT be transmitted to
alarm output.
▪ 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.
See also table below (Alarm output logic).

Auto restart
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
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.
