Part 5 Field Settings and Test Operation
shows the status of night-time low noise operation.
 0: unit is currently not operating under low noise restrictions
 1: unit is currently operating under low noise restrictions
Night-time low noise operation reduces the sound generated by the unit compared to
nominal operating conditions.
Night-time low noise operation can be set in mode 2. There are two methods to activate
night-time low noise operation of the outdoor unit system.
The first method is to enable an automatic night-time low noise operation by field
setting. The unit will operate at the selected low noise level during the selected time
frames.
The second method is to enable night-time low noise operation based on an external
input. For this operation an optional accessory is required.
shows the status of power consumption limitation operation.
 0: unit is currently not operating under power consumption limitations
 1: unit is currently operating under power consumption 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.
