*1 System controller should connect to TB7 at the outdoor and use a power supply unit together in multi-refrigerant-system.
For AG-150A, 24VDC should be used with the PAC-SC51KUA.
*2 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".
AG-150A and GB-50ADA 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".
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.
(Only a single outdoor unit can be connected to a HYBRID CITY MULTI system.)
2. M-NET power is supplied by the outdoor unit at TB3, while indoor unit and ME RC consume the M-NET power for transmission.
Consider power requirements with respect to the number of connected units for long M-NET wiring.
For details refer to 2-3 "System configuration restrictions".
3. Indoor units should be set with a branch number.
