2.3 Confirm the wired controller wires connection of each indoor unit

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.

controller only can control 64 units, and every unit can include max. 16 indoors, but the central controller

only displays the master indoor state.
