Priority during "Powerful" operation
If the indoor unit which is set for priority-room is operating at
"Powerful" operation, distribution of capacity to other indoor units will
be reduced. This means that the room of which the indoor unit is set
for priority-room will be cooled or heated much quicker than other
rooms.
Indoor or outdoor unit quiet operation priority
Pressing the "Quiet operation button" on the remote controller of the
indoor unit set for priority-room, will make the outdoor unit run quietly.
You do not have to set all operated indoor units to outdoor unit quiet
operation in this case. Running units in outdoor unit quiet operation
however, reduces the cooling/heating capacity.
Setting procedure
Slide the switch to the ON side for the switch that corresponds to the
piping connected to the indoor unit to be set. (In the figure below, it is
room A.)
Once the settings are complete, reset the power.

MODE
SETTING
The night quiet mode setting requires initial programming during
installation. Explain night quiet mode, as described below, to the
customer, and confirm whether or not the customer wants to use
night quiet mode.
Night quiet mode function
The night quiet mode function reduces operating noise of the outdoor
unit at nighttime. This function is useful if the customer is worried
about the effects of the operating noise on the neighbours.
Running units in night quiet mode however, reduces the cooling/
heating capacity.
Setting procedure
Remove the SW5 jumper switch.
Once the settings are complete, reset the power.
