Part 5 Field Settings and Test Operation
Mode 2-29:
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.
When operation parameters return to normal range, the capacity priority is switched OFF,
enable to reduce airflow rate depending on night-time low noise operation is still required
(end time for low night noise operation is not reached or external input night-time low
noise operation is still closed).
