2 When one system is to be controlled from two locations, up to two intelligent Touch Controller (In case of combining the intelligent
Touch Controller and Central Remote Controller, it is restricted to combine two Controllers in total), four Central Remote Controller
and 16 unified ON/OFF Controller can be connected. However, the maximum number of units that can be controlled is 128.
3 When a BS unit is used, the indoor units used in its downstream are not counted.
4 One port of one Interface for use in BACnet can have up to 64 groups (64 master indoor units with address). In case of adopting group
controlling, the circuit covered by the data station can have up to 128 indoor units including main and sub units.
