Pull the connected wires and make sure that they do not
disconnect. Then fix the wires in place in the wire clamps, by first
removing the screws (A), position the cables and then fix the
wire clamp again with the removed screws and the 4 delivered
screws (B). Secure firmly and be sure no tension is applied to
the terminals.

Priority-room setting
The priority-room setting requires initial programming during
installation. Explain the priority-room setting as described below to
the customer, and confirm whether or not the customer wants to use
priority-room setting.
Setting it in the guest and living rooms is convenient.
Priority-room setting function
The indoor unit for which priority-room setting is applied takes priority
in the following cases.
Operation mode priority
The operation mode of the indoor unit which is set for priority-room
takes precedence over operation mode of other indoor units. This
means that in case operation mode of these other indoor units is
different from the operation mode as requested in the room that is set
for priority-room, these indoor units will enter standby mode.
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.
