0010451167 PCB information – function selection（ON is 1, OFF is 0）
The standard condition for PCB in factory
SW1：4 bits are OFF
SW2：4 bits are OFF
SW3：4 bits are ON
SW4：2 bits are ON
SW5：4 bits are ON
SW1-SW2: used for indoor unit to set unit address from 1 to 16’
SW3-SW5: used for indoor unit to select different functions.(every dip switches are corresponding to
J1-J10.
SW2-4——logistic relationship of control function（door card control and remote/ wired control）0
means logistic relationship is “and”, 1 means the later coming is preferential.
J1，SW3-1——function selection-control type: 1 means remote control, 0 means wired control.
J2，SW3-2——function selection-temperature compensation in heating mode: 1means “yes”, 0means
“no”.
J3，SW3-3——function selection-outdoor communication: 1means “yes”, 0means “no”. This PCB
must be 1.
J4，SW3-4——function selection-heat pump unit: 1means “heat pump”, 0means “cooling only”.
1/60——test in short circuit, but in operation short circuit mustn’t be permitted.
CHECK——short spring switch control, it also can be used as switch of convertible type except for
testing.
J5，SW4-1——function selection-elevating function: 1means “yes”, 0means “no”.
J6，SW4-2——function selection –health function: 1means common (indoor fan motor running); 0
means special (indoor, outdoor running).
J7，SW5-1——function selection –swing mode: 1 means common（simultaneous motor）, 0 means
special (swing motor).
J8，SW5-2——function selection – system combination: 1means fixed frequency single unit, 0 means
fixed frequency multi split.
J9，SW5-3——function selection –group control: 1 stands for the master unit (its address in wired
controller is 0), 0 stands for the slave units (the address should be set by the dip switch, their addresses
only can be in the range: 1~15)
J10，SW5-4——function selection –preset: 1 no meaning, 0 no meaning
