Length of transmission wiring
Flow chart to determine the number of units to be connected
Notes
1 Condition
(A) means:
• Central control equipment + Indoor units + Outdoor units + other adapters £ 160 units
• Conversion number of central control equipment + Indoor units + Outdoor units + other adaptors £ 200 units
(B) means:
In case of connecting to DIII-NET
• Outdoor units must be counted to one system even in case of including 3 units. (Master + Master + Master = One system)
• The outdoor units connected by terminal Ex. Q1, Q2 (excepting terminal F1, F2) are regarded as one system.
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.
