2 When BS unit is installed, BS unit is not counted in the number. However, the indoor units after BS unit should be counted.
3 The outdoor unit is limited up to 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.
4 When the parallel interface is connected, the number of indoor units is 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.
