• A smart manager has two TCC-LINK communication lines: line 1 and line 2. Each line can contain up to 64
groups and 64 zones, and 128 groups and 128 zones can be set in total.
• A zone is a control unit consisting of a combination of any indoor units. You can make up to 64 zones pairing any
of up to 64 groups. For setting zones, see "8.Zone Setting".
