*1 For Wireless R/C and Signal receiver unit (SRU), channel 1, 2 and 3 are selectable and should be set to same channel.
*2 System controller should connect to TB7 at Outdoor and use power supply unit together in Multi-Refrigerant-System.
*3 When multiple system controllers are connected in the system, set the controller with more functions than others as a "main"
controller and others as "sub".
Make the setting to only one of the system controllers for "prohibition of operation from local remote controller".
NOTE:
1. Address should be set to Indoor units, LOSSNAY and system controller.
2. M-NET power is supplied by the Outdoor unit at TB3, while Indoor unit and ME remote controller consume the M-NET power for
transmission use. The power balance is needed to consider for long M-NET wiring. Details refer to 2-3 "System configuration restrictions".
3. When a PAR-30MAAC is connected to a group, no other MA remote controllers can be connected to the same group.
