Check and Change of Group Address of Indoor Unit
In group control or twin, triple, double twin operation, the group address is allocated to indoor unit by automatic
address setup after the system power supply has been turned on. From these addresses, “Header unit”: “1”
and “Follower unit”: “2” can be recognized. As the central control device (remote controller) communicates with
“Header unit” only, set up the group address from wired remote controller so that the indoor unit attached with
the interface becomes “Header unit”.
