When using central controller to control the indoor unit,
please pay attention to the address setting, as the 220,
250 and 280 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.
CAUTION
●
Please adjust the code ENC1 to the suitable position (both
system A and B should be adjusted for 200, 250 and 280
indoor unit).
Then expose the pipe (cover it with tapes after bending).
