Central control address
"Central control address" is used to make the central control devices recognize each indoor unit.
Address can be set from the central control devices either automatically or manually, or from wired remote controller devices manually.
In the case of group control in the VRF systems, one central control address is allocated to each indoor unit in a group control.
