limitation.
Power consumption limitation reduces the power
consumption of the unit compared to nominal operating
conditions.
Power consumption limitation can be set in mode 2. There
are two methods to activate power consumption limitation of
the outdoor unit system.
▪ The first method is to enable a forced power consumption
limitation by field setting. The unit will always operate at
the selected power consumption limitation.
▪ The second method is to enable power consumption
limitation based on an external input. For this operation
an optional accessory is required.
