PLEASE NOTE
1)
Motor is the abbreviation of Mitsubishi Electric. When Mitsubishi Electric has multiple external unit systems, connect the centralized control line to
TB7 “M1, M2” and insert the jumper cap of the centralized control switch CN41 on the outdoor unit PCB board to CN40.
2)
Haier air conditioning system has two baud rates. In the above table, the Haier baud rate is 9600 and the Haier-E baud rate is 2400.
3)
If the port polarity is marked as “None,” the wiring between the gateway wiring port and the air conditioning wiring port can be free; if the port
polarity displays “Yes,” the wiring between the gateway wiring port and the air conditioning wiring port must be in accordance with the manual. The
order marked below the ports corresponds to the order of the ports below the air conditioner port. For example: For Midea, the polarity of the gateway
wiring port is marked as “Yes,” so you need to connect the air conditioner X wiring port to the gateway X wiring port and the air conditioner Y wiring
port to the gateway Y wiring port.

when it displays “press and hold SET
for 5 seconds to reset,” press the “SET”
key for about 5 seconds, and the LCD
screen will display “reset successful” to
