2. Address should be set to Indoor units, LOSSNAY and system controller.
3. 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".
NOTE:
1. Outdoor units OC and OS in one refrigerant circuit system are automatically detected.
OC and OS are ranked in descending order of capacity. If units are the same capacity, they are ranked in ascending order
of their address.
*2 System controller should connect to TB7 at Outdoor and use power supply unit together in Multi-Refrigerant-System.
For AG-150A, 24VDC should be used with the PAC-SC51KUA.
For AE-200E, AE-50E, and EW-50E the power supply unit PAC-SC51KUA is unused.
*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".
AE-200E, AE-50E, EW-50E, BAC-HD150, and LM-AP are for exclusive use as a "main" system controller and cannot be used as a “sub”
system controller.
Make the setting to only one of the system controllers for "prohibition of operation from local remote controller".
*1 For Wireless R/C and Signal receiver unit (SRU), channel 1, 2 and 3 are selectable and should be set to same channel.
*4 The power supply unit is not necessary for AE-200E, AE-50E, EW-50E, BAC-HD150, and LM-AP.
4. Indoor units should be set with a branch number.
5. Assign an address to each of the sub BC controllers which equals the sum of the smallest address of the indoor units that are
connected to each sub BC controller and 50.
6. When a PAR-31MAA(E) is connected to a group, no other MA remote controllers can be connected to the same group.
