Connecting to LG VRF system
- CoolMasterNet has to be connected to the dedicated "Centralized Control Line" on Outdoor unit. It is not possible to connect to Indoor units. Centralized Control Line connectors on Outdoor unit are marked as CEN.A and CEN.B. If lines L3, L4, L5 or L6 are used in CoolMasterNet, make sure to connect CEN.A to A and CEN.B to B on CoolMasterNet side.
- Only two Control devices can be connected to the same Centralized Control Line. One of them must be Master and another - Slave. Thus, if any other control device, except CoolMasterNet, is connected to the same line make sure to separate them as Master/Slave. On CoolMasterNet Master/Slave settings can be done with below commands (assuming L7 is connected):
Master setting:
| >line master L7 1 OK |
Slave setting:
| >line master L7 0 OK |
