( ) Address
*1: When the power supply unit is not connected to the transmission line for centralized control, disconnect the male power supply
connector (CN41) from ONE heat source unit in the system and connect it to CN40.
*2: If a system controller is used, set SW5-1 on all of the heat source units to ON.

• ( ) Address
• Daisy-chain terminals (TB3) on heat source units in the same refrigerant system together.
• Leave the power jumper connector on CN41 as it is. When connecting a system controller
to the transmission line (TB7) for centralized control, refer to [Fig. 11.3.1], [Fig. 11.3.2], or
DATA BOOK.
