1167E 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
SW3-SW5: used for indoor unit to select different functions.(every dip switches are corresponding to J1-J10.
SW2-4üülogistic relationship of control function˄door card control and remote/ wired control˅0 means
logistic relationship is “and”, 1 means the later coming is preferential.
J1ˈSW3-1üüfunction selection-control type: 1 means remote control, 0 means wired control.
J2ˈSW3-2üüfunction selection-temperature compensation in heating mode: 1means “yes”, 0means “no”.
J3ˈSW3-3üüfunction selection-outdoor communication: 1means “yes”, 0means “no”. This PCB must be 1.
J4ˈSW3-4üüfunction selection-heat pump unit: 1means “heat pump”, 0means “cooling only”.
1/60üütest in short circuit, but in operation short circuit mustn’t be permitted.
CHECKüüshort spring switch control, it also can be used as switch of convertible type except for testing.
J5ˈSW4-1üüfunction selection-elevating function: 1means “yes”, 0 means “no”.
J6ˈSW4-2üüfunction selection –health function: 1means common (indoor fan motor running); 0 means
special (indoor, outdoor running).
J7ˈSW5-1üüfunction selection –swing mode: 1 means common˄simultaneous motor˅, 0 means special
(swing motor).
J8ˈSW5-2üüfunction selection – system combination: 1means fixed frequency single unit, 0 means fixed
frequency multi split.
J9ˈSW5-3üüfunction 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)

1167E PCB information- control type
Control type selection between remote and wired: select by dip switch J1, SW3-1˄1 means remote control˗
0 means wired control.)
For remote control type, please use remote controller YR-H71, and a remote receiver is equipped with
indoor unit. For wired control type, wired controller YR-E12 will be used, 3-core shied wire is equipped with
SW1-SW2: used for indoor unit to set unit address from 1 to 128’
