Part 5 Field Settings and Test Operation
Capacity priority
When the night-time low noise operation is in use, performance of system might
drop because airflow rate of outdoor unit is reduced.
Default value: 0. Capacity priority cannot be used.
Field setting 1: Capacity priority can temporary cancel the night-time low noise
operation. Capacity priority can be initiated when certain operation parameters
approach the safety setting:
 Raise in high pressure during cooling.
 Drop in low pressure during heating.
 Raise of discharge pipe temperature.
 Raise of inverter current.
 Raise of fin temperature inverter PCB.

Power consumption limitation level (step 1) via the external control adaptor
(DTA104A61/62)
If the system needs to run under power consumption limitation conditions when an
external signal is sent to the unit, this setting defines the level power consumption
limitation that will be applied for step 1. The level is according to the table.
Default value: 3
