Make sure the position of SW1 and SW20-1 on wired controller
Old type wired controller is SW20-1; new type wired controller is SW1.
Note: 1. D1, D2 are the diode, if the two terminals are disconnected, the state is "1"; if the two terminals
are connected with a jumper, the state is "0".
2. Only when two controllers control one indoor unit, one of wired controllers can be set as slave controller,
and set SW20-[1] as ON, the others keep the state when out of factory, set SW20-[1] as OFF.
3. The old type: there are resistors of J03 and J06 beside the dip switch.

The third, fourth bit: control range, 00: 1~64, 01: 65~128, 10: 129~192, 11: 193~256. Every central
controller only can control 64 units, and every unit can include ma . 16 indoors, but the central controller
only displays the master indoor state.
