System controller
*1 When a power supply unit is not connected to the centralized control transmission cable, move the power jumper from CN41 to CN40 on only one of the outdoor units (except 208–230 V
model). When the System controller is connected to TB7 side and 208–230 V outdoor unit model is used, connect a power supply unit to TB7 side. If a power supply unit cannot be
used, connect the System controller to TB3 side. Up to three System controllers can be connected to TB3 side.
*2 If a system controller is used, set SW5-1 on all of the outdoor units to ON.
*3 When a PAR-31MAA is connected to a group, no other MA remote controllers can be connected to the same group.
