TROUBLE SHOOTING
For 200T1 unit, two mainboards in the electric control
should set the code ENC1 to 8;
For 250T1 unit, a mainboard in the electric control should
set the code ENC1 to 8; the other one should set the code
ENC1 to 9;
For 280T1 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 200T1,
250T1 and 280T1 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.
