0010451167 PCB information- control type
Control type selection between remote and wired: select by dip switch J1, SW3-1˄1 means remote control˗
0means wired control˅.
For remote control type, please use remote controller, and a remote receiver is equipped with indoor unit.
Door card control: controls ON/OFF, the start up setting will comply with last time request memorized
according to condition memorize function. Its difference with emergency switch of convertible type unit lies:

The function combination between door card and remote/wired control type: select by dip switch: SW2-4˄0
means “and”, 1 means later coming is preferential.˅
Dip switch position in central control type: the addresses ˄SW1:1~4˗SW2:1~4˅of indoor units connected
with central controller can not repeat. In principle, they should be in the order from small to big.
Wiring request in central control type: port A-B is connected with indoor port CN16˄A-B˅through 2-core
shield wire. Requirements:
1. Port A connects with port CN16˄A˅of all indoor units.
2. Port B connects with port CN16˄B˅of all indoor units.
LED in indoor PCB:
1. LED1˖is the state lamp for remote receiver as well as failure lamp. If indoor unit is normal, LED1 is on,
or if failure occurs, LED1 flashes regularly, and you can adjust failure type according to the flash times.
2. LED2˖is used for multi split units as communication lamp. If communication between indoor and
outdoor is normal, LED2 will be on.
3. LED3˖is used for single split units as communication lamp. If communication between indoor and
outdoor is normal, LED3 will be on.
4. LED4ǃLED5˖is the lamp that shows the data receiving or sending between wired controller and PCB,
If LED4ǃLED5 be on in turn, communication between wired controller and PCB is normal.
