Indoor unit central control address and SW1/SW2 setting
• SW1/SW2
Set the number of indoor units to be connected.
Set the maximum of the indoor unit central control address according to the table below.
The factory setting is “3F” (64 units connected).
(*) Set the indoor unit central control address from 1 to 64 consecutively.
This means that the maximum of the central control address equals the number of connected
indoor units.
However, if an address is omitted, the maximum of the central control address differs from the
number of connected indoor units. In this case, set the maximum of the central control address
according to the table below.
Note:
The system works normally when the set value is larger than the maximum.
However, it will result in communication loss.
