Please adjust the code ENC1 to the suitable position (both
system A and B should be adjusted for 450 and 560 indoor
unit).
● For 450 unit, two mainboards in the electric control
should set the code ENC1 to 8;
● For 560 unit, two mainboards in the electric control
should set the code to 9.
For the same indoor unit, every mainboard must be differ-
ent indoor unit addresses and network addresses.
When using central controller to control the indoor unit,
please pay attention to the address setting, as the 450
and 560 units have two or more mainboards. We
suggest setting the neighbor address for the mainboards
in the same indoor unit. When using a central controller for
controlling, mainboards in the same unit must be opened
and closed at the same time, for avoiding the unexpected
incident.
