Daikin D-BACS - Number of Connectable Units

36 5.1 Number of Connectable Units
Fundamental of DIII-NET
5. Number of Connectable Units
5.1 Number of Connectable Units
Note:
1. When you have a 2 central control system (to control one system from 2 central locations), 2 intelligent Touch
Controllers, 4 central remote controllers and 16 unified ON/OFF controllers can be connected. However, a maximum
of 128 units can only be controlled.
2. When you connect 8 or more central control equipment, it is required to satisfy the following conditions. (The following
conditions are not required to be considered when the number of controller is 7 or less.)
 Central control equipment + Indoor units + Outdoor units + other adaptors ≤ 160 units
 Central Conversion number of central control equipment (*) + Indoor units + Outdoor units + other adaptors ≤
200 units
(Note: (*) is converted one central control equipment except unified ON/OFF controller as 10 units.)
3. When BS unit is installed, BS unit is not counted in the number. However, the indoor units after BS unit should be
counted.
4. The outdoor unit is limited up to a maximum of 10 units, and also the number of function units is also limited up to 5.
However, if the sequential start setting is possible, up to 10 function units can be connected.
5. When the parallel interface is connected, the number of indoor units are limited up to 64 groups (128 units). When you
judge whether the number of the connectable units is possible, refer to the flow chart on the next page.
