8.2 Network address settings
1) The network address is set based on communication
between the indoor and outdoor units. The address is the same
as the indoor address, and there is no need to set them
separately.
2) The central control of indoor units can be done on an
outdoor unit. There is no need to control indoor unit separately.
3) For previous control of the indoor units, the network can be
set by connecting (X, Y, E) terminals. There is no need to set
the network address. The network can also be set by outer
network module and main board (CN20).
The system has a total of 64 units (0-63). Each has only one
system address code. If an address is duplicated, an error
will occur.
Switch off the power before configuring the settings, or an
error will occur.
