5.2 Flow Chart to Determined the Number of Units to Connected
Note 1:
Condition
(A) means;
 Central control equipment + Indoor units + Outdoor units + other adaptors ≤ 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.
Note:
1. 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.
2. When a BS unit is used, the indoor units used in its downstream are not counted.
3. 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.
